General Power Tool Safety Warnings

Read all safety warnings, instructions, illustrations and speciﬁcations pro-

vided with this power tool. Failure to follow all instructions listed below may

result in electric shock, re and/or serious injury.

SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE

The term “power tool” in the warnings refers to your mains-operated (corded) power tool or

battery-operated (cordless) power tool.

1. Work area safety

a. Keep work area clean and well lit. Clut-

tered or dark areas invite accidents.

b. Do not operate power tools in explosive

atmospheres, such as in the presence of

ammable liquids, gases or dust. Power

tools create sparks which may ignite the

dust or fumes.

c. Keep children and bystanders away while

operating a power tool. Distractions can

cause you to lose control.

2. Electrical safety

a. Power tool plugs must match the outlet.

Never modify the plug in any way. Do

not use any adapter plugs with earthed

(grounded) power tools. Unmodied plugs

and matching outlets will reduce risk of

electric shock.

b. Avoid body contact with earthed or

grounded surfaces, such as pipes, radia-

tors, ranges and refrigerators. There is an

increased risk of electric shock if your body

is earthed or grounded.

c. Do not expose power tools to rain or wet

conditions. Water entering a power tool

will increase the risk of electric shock.

d. Do not abuse the cord. Never use the cord

for carrying, pulling or unplugging the

power tool. Keep cord away from heat,

oil, sharp edges or moving parts. Dam-

aged or entangled cords increase the risk of

electric shock.

e. When operating a power tool outdoors,

use an extension cord suitable for outdoor

use. Use of a cord suitable for outdoor use

reduces the risk of electric shock.

f. If operating a power tool in a damp loca-

tion is unavoidable, use a Ground Fault

Circuit Interrupter (GFCI) protected

supply. Use of a GFCI reduces the risk of

electric shock.

3. Personal safety

a. Stay alert, watch what you are doing and

use common sense when operating a

power tool. Do not use a power tool while

you are tired or under the inuence of

drugs, alcohol or medication. A moment

of inattention while operating power tools

may result in serious personal injury.

b. Use personal protective equipment.

Always wear eye protection. Protective

equipment such as a dust mask, non-skid

safety shoes, hard hati or hearing protec-

tion used for appropriate conditions will

reduce personal injuries.

c. Prevent unintentional starting. Ensure the

switch is in the off-position before con-

necting to power source and/or BATTERY

pack, picking up or carrying the tool. Car-

rying power tools with your nger on the

switch or energizing power tools that have

the switch on invites accidents.

d. Remove any adjusting key or wrench be-

fore turning the power tool on. A wrench

or a key left attached to a rotating part

of the power tool may result in personal

injury.

e. Do not overreach. Keep proper footing and

balance at all times. This enables better

control of the power tool in unexpected

situations.

f. Dress properly. Do not wear loose cloth-

ing or jewelry. Keep your hair and clothing

away from moving parts. Loose clothes,

jewelry or long hair can be caught in mov-

ing parts.

g. If devices are provided for the connec-

tion of dust extraction and collection

facilities, ensure these are connected and

properly used. Use of dust collection can

reduce dust-related hazards.

h. Do not let familiarity gained from fre-

quent use of tools allow you to become

complacent and ignore tool safety prin-

ciples. A careless action can cause severe

injury within a fraction of a second.

4. Power tool use and care

a. Do not force the power tool. Use the cor-

rect power tool for your application. The

correct power tool will do the job bet-

ter and safer at the rate for which it was

designed.

b. Do not use the power tool if the switch

does not turn it on and off. Any power tool

that cannot be controlled with the switch is

dangerous and must be repaired.

c. Disconnect the plug from the power

source and/or remove the BATTERY pack,

if detachable, from the power tool before

making any adjustments, changing ac-

cessories, or storing power tools. Such

preventive safety measures reduce the risk

of starting the power tool accidentally.

d. Store idle power tools out of the reach

of children and do not allow persons

unfamiliar with the power tool or these

instructions to operate the power tool.

Power tools are dangerous in the hands of

untrained users.

e. Maintain power tools and accessories.

Check for misalignment or binding of

moving parts, breakage of parts and any

other condition that may affect the power

tool's operation. If damaged, have the

power tool repaired before use. Many

accidents are caused by poorly maintained

power tools.

f. Keep cutting tools sharp and clean. Prop-

erly maintained cutting tools with sharp

cutting edges are less likely to bind and are

easier to control.

g. Use the power tool, accessories and tool

bits etc. in accordance with these instruc-

tions, taking into account the working

conditions and the work to be performed.

Use of the power tool for operations differ-

ent from those intended could result in a

hazardous situation.

h. Keep handles and grasping surfaces dry,

clean and free from oil and grease. Slip-

pery handles and grasping surfaces do not

allow for safe handling and control of the

tool in unexpected situations.

5. Battery tool use and care (cord-

less only)

a. Recharge only with the charger speciﬁed

by the manufacturer. A charger that is

suitable for one type of BATTERY pack may

create a risk of re when used with another

BATTERY pack.

b. Use power tools only with speciﬁcally

designated BATTERY packs. Use of any

other BATTERY packs may create a risk of

injury and re.

c. When BATTERY pack is not in use, keep it

away from other metal objects, like paper

clips, coins, keys, nails, screws or other

small metal objects, that can make a

connection from one terminal to another.

Shorting the BATTERY terminals together

may cause burns or a re.

d. Under abusive conditions, liquid may be

ejected from the BATTERY; avoid contact.

If contact accidentally occurs, ush with

water. If liquid contacts eyes, additionally

seek medical help. Liquid ejected from the

BATTERY may cause irritation or burns.

e. Do not use a BATTERY pack or tool that is

damaged or modiﬁed. Damaged or modi-

ed batteries may exhibit unpredictable

behavior resulting in re, EXPLOSION or

risk of injury.

f. Do not expose a BATTERY pack or tool to

ﬁre or excessive temperature. Exposure to

re or temperature above 265 °F / 130 °C

may cause explosion.

g. Follow all charging instructions and do

not charge the BATTERY pack or tool

outside the temperature range speciﬁed

in the instructions. Charging improperly or

at temperatures outside the specied range

may damage the BATTERY and increase the

risk of re.

General Power Tool Safety Warnings

SAVE THESE INSTRUCTIONS

1. Safety warnings common for

grinding or cutting-off operations

a. This power tool is intended to function as

a cut-off tool. Read all safety warnings, in-

structions, illustrations and speciﬁcations

provided with this power tool. Failure to

follow all instructions listed below may

result in electric shock, re and/or serious

injury.

b. Operations such as grinding, sanding, wire

brushing, polishing or hole cutting are not

to be performed with this power tool. Op-

erations for which the power tool was not

designed may create a hazard and cause

personal injury.

c. Do not convert this power tool to operate

in a way which is not speciﬁcally designed

and speciﬁed by the tool manufacturer.

Such a conversion may result in a loss of

control and cause serious personal injury.

d. Do not use accessories which are not

speciﬁcally designed and speciﬁed by the

tool manufacturer. Just because the acces-

sory can be attached to your power tool, it

does not assure safe operation.

e. The rated speed of the accessory must

be at least equal to the maximum speed

marked on the power tool. Accessories

running faster than their rated speed can

break and y apart.

f. The outside diameter and the thickness of

your accessory must be within the capac-

ity rating of your power tool. Incorrectly

sized accessories cannot be adequately

guarded or controlled.

g. The dimensions of the accessory mounting

must ﬁt the dimensions of the mounting

hardware of the power tool. Accessories

that do not match the mounting hardware

of the power tool will run out of balance,

vibrate excessively and may cause loss of

control.

h. Do not use a damaged accessory. Before

each use inspect the accessory such as

abrasive wheels for chips and cracks,

backing pad for cracks, tear or excess

wear, wire brush for loose or cracked

wires. If power tool or accessory is

dropped, inspect for damage or install

an undamaged accessory. After inspect-

ing and installing an accessory, position

yourself and bystanders away from the

plane of the rotating accessory and run

the power tool at maximum no-load speed

for one minute. Damaged accessories will

normally break apart during this test time.

i. Wear personal protective equipment.

Depending on application, use face shield,

safety goggles or safety glasses. As ap-

propriate, wear dust mask, hearing protec-

tors, gloves and workshop apron capable

of stopping small abrasive or workpiece

fragments. The eye protection must be

capable of stopping ying debris generated

by various applications. The dust mask or

respirator must be capable of ltrating par-

ticles generated by the particular applica-

tion. Prolonged exposure to high intensity

noise may cause hearing loss.

j. Keep bystanders a safe distance away

from work area. Anyone entering the

work area must wear personal protective

equipment. Fragments of workpiece or of

a broken accessory may y away and cause

injury beyond immediate area of operation.

k. Hold the power tool by insulated grip-

ping surfaces only, when performing an

operation where the cutting accessory

6. Service

a. Have your power tool serviced by a quali-

ﬁed repair person using only identical

replacement parts. This will ensure that

the safety of the power tool is maintained.

b. Never service damaged BATTERY packs.

Service of BATTERY packs should only be

performed by the manufacturer or autho-

rized service providers. (cordless only)

may contact hidden wiring or its own

cord. Cutting accessory contacting a ″live″

wire may make exposed metal parts of the

power tool ″live″ and could give the opera-

tor an electric shock. (corded only)

l. Hold the power tool by insulated grip-

ping surfaces only, when performing an

operation where the cutting accessory

may contact hidden wiring. Contact with a

"live" wire will also make exposed metal

parts of the power tool "live" and could

give the operator an electric shock. (cord-

less only)

m. Position the cord clear of the spinning

accessory. If you lose control, the cord may

be cut or snagged and your hand or arm

may be pulled into the spinning accessory.

n. Never lay the power tool down until the

accessory has come to a complete stop.

The spinning accessory may grab the

surface and pull the power tool out of your

control.

o. Do not run the power tool while carrying

it at your side. Accidental contact with the

spinning accessory could snag your cloth-

ing, pulling the accessory into your body.

p. Regularly clean the power tool’s air vents.

The motor’s fan will draw the dust inside

the housing and excessive accumulation

of powdered metal may cause electrical

hazards.

q. Do not operate the power tool near am-

mable materials. Sparks could ignite these

materials.

r. Do not use accessories that require liquid

coolants. Using water or other liquid cool-

ants may result in electrocution or shock.

2. Kickback and related warnings

Kickback is a sudden reaction to a pinched or

snagged rotating wheel, backing pad, brush

or any other accessory. Pinching or snagging

causes rapid stalling of the rotating accessory

which in turn causes the uncontrolled power

tool to be forced in the direction opposite of

the accessory’s rotation at the point of the

binding.

For example, if an abrasive wheel is snagged

or pinched by the workpiece, the edge of the

wheel that is entering into the pinch point can

dig into the surface of the material causing the

wheel to climb out or kick out. The wheel may

either jump toward or away from the operator,

depending on direction of the wheel’s move-

ment at the point of pinching. Abrasive wheels

may also break under these conditions.

Kickback is the result of power tool misuse

and/or incorrect operating procedures or con-

ditions and can be avoided by taking proper

precautions as given below.

a. Maintain a ﬁrm grip with both hands on

the power tool and position your body

and arms to allow you to resist kickback

forces. Always use auxiliary handle, if pro-

vided, for maximum control over kickback

or torque reaction during start-up. The

operator can control torque reactions or

kickback forces, if proper precautions are

taken.

b. Never place your hand near the rotating

accessory. Accessory may kickback over

your hand.

c. Do not position your body in the area

where power tool will move if kickback

occurs. Kickback will propel the tool in di-

rection opposite to the wheel’s movement

at the point of snagging.

d. Use special care when working corners,

sharp edges, etc. Avoid bouncing and

snagging the accessory. Corners, sharp

edges or bouncing have a tendency to snag

the rotating accessory and cause loss of

control or kickback.

e. Do not attach a saw chain woodcarving

blade, segmented diamond wheel with

a peripheral gap greater than 10 mm

(13/32”) or toothed saw blade. Such

blades create frequent kickback and loss of

control.

3. Safety warnings speciﬁc for

grinding and cutting-off opera-

tions

a. Use only wheel types that are speciﬁed

for your power tool and the speciﬁc guard

designed for the selected wheel. Wheels

for which the power tool was not designed

TG503 Tuck Point Grinder Guard OSI Final 20230606.indd 6TG503 Tuck Point Grinder Guard OSI Final 20230606.indd 6 6/6/2023 1:42:57 PM6/6/2023 1:42:57 PM

SAVE THESE INSTRUCTIONS

Cut-Off Machine Safety Warnings

cannot be adequately guarded and are

unsafe.

b. The grinding surface of center depressed

wheels must be mounted below the plane

of the guard lip. An improperly mounted

wheel that projects through the plane of

the guard lip cannot be adequately pro-

tected.

c. The guard must be securely attached to

the power tool and positioned for maxi-

mum safety, so the least amount of wheel

is exposed towards the operator. The

guard helps to protect the operator from

broken wheel fragments, accidental contact

with wheel and sparks that could ignite

clothing.

d. Wheels must be used only for speciﬁed

applications. For example: do not grind

with the side of cut-off wheel. Abrasive

cut-off wheels are intended for peripheral

grinding, side forces applied to these

wheels may cause them to shatter.

e. Always use undamaged wheel anges

that are of correct size and shape for your

selected wheel. Proper wheel anges sup-

port the wheel thus reducing the possibil-

ity of wheel breakage. Flanges for cut-off

wheels may be different from grinding

wheel anges.

f. Do not use worn down wheels from larger

power tools. A wheel intended for larger

power tool is not suitable for the higher

speed of a smaller tool and may burst.

g. When using dual purpose wheels always

use the correct guard for the application

being performed. Failure to use the correct

guard may not provide the desired level

of guarding, which could lead to serious

injury.

4. Additional safety warnings spe-

ciﬁc for cutting-off operations

a. Do not “jam” the cut-off wheel or apply

excessive pressure. Do not attempt to

make an excessive depth of cut. Over-

stressing the wheel increases the loading

and susceptibility to twisting or binding of

the wheel in the cut and the possibility of

kickback or wheel breakage.

b. Do not position your body in line with

and behind the rotating wheel. When the

wheel, at the point of operation, is moving

away from your body, the possible kickback

may propel the spinning wheel and the

power tool directly at you.

c. When the wheel is binding or when inter-

rupting a cut for any reason, switch off

the power tool and hold it motionless

until the wheel comes to a complete stop.

Never attempt to remove the cutoff wheel

from the cut while the wheel is in motion

otherwise kickback may occur. Investigate

and take corrective action to eliminate the

cause of wheel binding.

d. Do not restart the cutting operation in the

workpiece. Let the wheel reach full speed

and carefully re-enter the cut. The wheel

may bind, walk up or kickback if the power

tool is restarted in the workpiece.

e. Support panels or any oversized work-

piece to minimize the risk of wheel pinch-

ing and kickback. Large workpieces tend

to sag under their own weight. Supports

must be placed under the workpiece near

the line of cut and near the edge of the

workpiece on both sides of the wheel.

f. Use extra caution when making a “pocket

cut” into existing walls or other blind

areas. The protruding wheel may cut gas

or water pipes, electrical wiring or objects

that can cause kickback.

g. Do not attempt to do curved cutting. Over-

stressing the wheel increases the loading

and susceptibility to twisting or binding of

the wheel in the cut and the possibility of

kickback or wheel breakage, which can lead

to serious injury.

SAVE THESE INSTRUCTIONS

Intended Use

This tuckpointing guard and respective small

angle grinder is intended for use in cutting mor-

tar or masonry type materials.

The guard includes a dust port which allows it

to be connected to a vacuum hose which can

be connected to an appropriate dust extractor

vacuum. (See OSHA Silica Regulation concern-

ing vacuum, CFM and lter requirements for

tuckpointing applications / mortar removal.)

The TG503 tuckpointing guard is designed for

use with two types of Bosch small angle grind-

ers, the type having threaded spindle (model

GWS) and the X-LOCK (model GWX). This guard

is intended for use with Type 1A/41 diamond

wheels, or specially designed sandwiched dia-

mond wheels, available with X-LOCK or 7/8”

arbor, for mounting on the two types of Bosch

angle grinders.

Use this tuckpointing guard with a Bosch 4-1/2 inch, 5 inch, or 6 inch small

angle grinder only as intended. Unintended use may result in personal injury

and property damage.

GFCI and personal protection devices like elec-

trician’s rubber gloves and footwear will further

enhance your personal safety.

Do not use AC only rated tools with a DC pow-

er supply. While the tool may appear to work,

the electrical components of the AC rated tool

are likely to fail and create a hazard to the op-

erator.

Keep handles dry, clean and free from oil and

grease. Slippery hands cannot safely control

the power tool.

Develop a periodic maintenance schedule for

your tool. When cleaning a tool be careful not

to disassemble any portion of the tool since

internal wires may be misplaced or pinched

or safety guard return springs may be improp-

erly mounted. Certain cleaning agents such as

gasoline, carbon tetrachloride, ammonia, etc.

may damage plastic parts.

Wear hearing protection. Prolonged exposure

to high intensity noise can cause hearing loss.

Use thick cushioned gloves and limit the ex-

posure time by taking frequent rest periods.

Vibration caused by the use of power tools may

be harmful to your hands and arms.

This tool must be used with Respiratory Pro-

tection sufﬁcient to block dusts including

silica from concrete cutting. N-95 rated masks

minimum or full respirator protection for the

operator and others in the work area.

Dust collection is required with a vacuum or

other suitable dust collection system for con-

crete/masonry applications.

Do not use vacuum or other dust collection

system when cutting metal. Sparks from metal

cutting can cause re in the collector.

Some dust created by pow-

er sanding, sawing, grind-

ing, drilling, and other construction activities

contains chemicals known to cause cancer,

birth defects or other reproductive harm.

Some examples of these chemicals are:

• Lead from lead-based paints,

• Crystalline silica from bricks and cement

and other masonry products, and

• Arsenic and chromium from chemically-

treated lumber.

Your risk from these exposures varies, depend-

ing on how often you do this type of work. To

reduce your exposure to these chemicals: work

in a well ventilated area, and work with ap-

proved safety equipment, such as those dust

masks that are specially designed to lter out

microscopic particles.
