exercise to restore normal blood circulation. If any of
the symptoms appear, seek medical advice immediately.
7) Clothing must be sturdy and snug fitting, but allow
complete freedom of movement. Never wear loose fitting
jackets, scarves, neckties, jewelry, flared or cuffed
pants or anything that could become caught on controls
or moving parts. Wear long pants to protect your legs.
Protect your hands with heavy duty, non-slip gloves to
improve your grip. Good footing is most important when
operating the SURFACE GRINDER.
Wear sturdy boots with non-slip soles. Steel-toed safety
shoes are highly recommended. Never wear tennis
shoes or other, similar type shoes which afford little or
no protection. Wear an approved safety hard hat to
protect the operator’(s’) head(s) where there is a danger
of head injuries. Noise, generated by the SURFACE
GRINDER and the actual process itself, can damage
your hearing.Wear approved sound barriers (ear plugs
or ear mufflers) to protect your hearing. Continuous and
regular operators should have their hearing checked
regularly.
8) Visually inspect the SURFACE GRINDER, components,
tools and accessories for damaged or worn parts.
BEFORE each use:
a) Disconnect the power source cable.
b) Clean and remove all accumulated foreign matter
from the wheels and determine that each rotates
freely.
c) Clean and remove all accumulated foreign matter
from inside the mainframe area.
d) Inspect the V-belt drive for proper tension, wear and
general condition. Replace each component as
necessary.
e) Inspect the multi-accessory disc and gimbal head
assembly for excessive wear and structural
integrity. Replace each component as necessary.
The multi-accessory disc rotating at high speed
during the specific process can be subject to high
wear rates if the installed attachment is not properly
maintained and/or replaced at regular service
intervals.
f) Determine that operator controls work freely, all
safety devices are operative and information decals
are readable.
g) Check to see that the SURFACE GRINDER and all
related accessories are in good, mechanical
condition BEFORE utilization.
h) Reconnect the power source cable as applicable.
9) Contact appropriate representatives to determine if/
where electrical cables, gas lines and other hazardous
items are buried under the work surface BEFORE
utilization. The SURFACE GRINDER and related
accessories are not insulated. Contact with buried
electrical cables, gas lines and other hazardous items
can result in electrocution and/or an explosion.
10) Know how the controls operate. Know how to stop the
electric motor quickly in an emergency. Always start
the electric motor according to the instructions as
outlined in this manual to minimize the possibility of
unexpected contact with the work surface. Unexpected
contact with the work surface can cause loss of
machine control, and the possibility of property damage
and/or personal injury.
11) Ground the electrically powered SURFACE GRINDER
motor securely. Determine that any “grounding” wire and/
or device is, in fact, properly grounding the motor. Failure
to properly ground the motor may cause an electrical
shock and/or electrocution, resulting in property
damage and personal, injury including death. Electrical
wiring and all connections should be performed by a
qualified electrician. The electric motor is designed to
operate from a 115 AC power source.
12) When operating the SURFACE GRINDERs on a surface
containing water or other electrically conducting liquid,
special precautions must be taken to minimize the
possibility of operator electrocution. Once such
precaution is to wire and operate the electric motor from
a clean, 20 Ampere, 115 Volt AC power source in
conjunction with a ground fault circuit interrupter (GFCI).
A GFCI is a safety device that disconnects power from
a circuit to a load when a potentially dangerous condition
occurs. The GFCI opens the circuit when the fault
current flow from a power line to a ground exceeds the
safe limit for humans.
The GFCI protects against harmful electrical shock to
a person caused by contact with a defective electrical
product. A GFCI differs from a fuse or circuit breaker. A
fuse or circuit breaker opens the circuit when the total
current flow in the power line exceeds the safe limit of
the power line. They are designed to protect against
fire caused by overheating of the power line. Use of a
GFCI gives on the job protection from electrical shock
hazards caused by ground faults in commercial,
industrial and residential applications.They are simple
and easy to use: plug a portable GFCI into any suitable,
grounded extension cord and plug the SURFACE
GRINDER into the GFCI for automatic protection
against ground faults.
For specific information, consult current National
Electrical Code® publications and OSHA publications
210-22D (or current revision) for construction sites and
555-3 (or current revision) for use around any area
containing water.
13) Never exceed the recommended capacities of the
SURFACE GRINDER. Refer to the Specifications
