SAFETY INSTRUCTIONS

EYE PROTECTION which conforms to ANSI specifications and provides protection

against flying particles both from the FRONT and SIDE should ALWAYS be worn

by the operator and others in the work area when loading, operating or servicing

this tool. Eye protection is required to guard against flying fasteners and debris,

which could cause severe eye injury.

The employer and/or user must ensure that proper eye protection is worn. Eye

protection equipment must conform to the requirements of the American National

Standards Institute, ANSI Z87.1-1989 and provide both frontal and side protection.

NOTE: Non-side shielded spectacles and face shields alone do not provide ade-

quate protection.

CAUTION: ADDITIONAL SAFETY PROTECTION will be required in some environ-

ments. For example, the working area may include exposure to noise level which

can lead to hearing damage. The employer and user must ensure that any necessary

hearing protection is provided and used by the operator and others in the work area.

Some environments will require the use of head protection equipment. When

required, the employer and user must ensure that head protection conforming to

ANSI Z89.1 1986 is used.

AIR SUPPLY AND CONNECTIONS

Do not use oxygen, combustible gases, or bottled gases as a power source for this

tool as tool may explode, possibly causing injury.

Do not use supply sources which can potentially exceed 200 P.S.I.G. as tool may

burst, possibly causing injury.

The connector on the tool must not hold pressure when air supply is disconnect-

ed. If a wrong fitting is used, the tool can remain charged with air after discon-

necting and thus will be able to drive a fastener even after the air line is discon-

nected possibly causing injury.

Do not pull trigger or depress contact arm while connected to the air supply as the

tool may cycle, possibly causing injury.

Always disconnect air supply: 1.) Before making adjustments; 2.) When servicing

the tool; 3.) When clearing a jam; 4.) When tool is not in use; 5.) When moving to a

different work area, as accidental actuation may occur, possibly causing injury.

LOADING TOOL

When loading tool: 1.) Never place a hand or any part of body in fastener dis-

charge area of tool; 2.) Never point tool at anyone; 3.) Do not pull the trigger or

depress the trip as accidental actuation may occur, possibly causing injury.

OPERATION

Always handle the tool with care: 1.) Never engage in horseplay; 2.) Never pull

the trigger unless nose is directed toward the work; 3.) Keep others a safe dis-

tance from the tool while tool is in operation as accidental actuation may occur,

possibly causing injury.

The operator must not hold the trigger pulled on contact arm tools except dur-

ing fastening operation as serious injury could result if the trip accidentally con-

tacted someone or something, causing the tool to cycle.

Keep hands and body away from the discharge area of the tool. A contact arm tool

may bounce from the recoil of driving a fastener and an unwanted second fasten-

er may be driven possibly causing injury.

Check operation of the contact arm mechanism frequently. Do not use the tool if

the arm is not working correctly as accidental driving of a fastener may result. Do

not interfere with the proper operation of the contact arm mechanism.

Do not drive fasteners on top of other fasteners or with the tool at an overly steep

angle as this may cause deflection of fasteners which could cause injury.

Do not drive fasteners close to the edge of the work piece as the wood may split,

allowing the fastener to be deflected possibly causing injury.

MAINTAINING THE TOOL

When working on air tools note the warnings in this manual and use extra care

when evaluating problem tools.

N95RHN TOOL SPECIFICATIONS

All screws and nuts are metric.

FASTENER SPECIFICATIONS:

This tool uses a wide range of nail sizes in lengths of 2” to 3-1/2” (50 - 90mm) and shank

diameters of .113” to .148” (2.8 - 3.3mm)

TOOL AIR FITTING:

This tool uses a 1/4” N.P.T. male plug. The inside diameter should be .275” (7mm) or

larger. The fitting must be capable of discharging tool air pressure when disconnected from

the air supply. The connector socket on the air hose should be .275” (7mm) inside diameter

or larger.

OPERATING PRESSURE:

70 to 100 p.s.i.g. (4.9 to 7.0 kg/cm2). Select the operating pressure within this range for

best fastener performance.

DO NOT EXCEED THIS RECOMMENDED OPERATING PRESSURE.

AIR CONSUMPTION:

The N95RHN requires 7.8 cubic feet per minute of free air to operate at the rate of

100 nails per minute, at 80 p.s.i.g. (5.6 kg/cm2). Take the actual rate at which the tool will

be run to determine the amount of air required. For instance, if your nail usage averages 50

nails per minute, you need 50% of the 7.8 c.f.m. which is required to operate the tool at 100

nails per minute.

BOSTITCH OFFERS TWO TYPES OF OPERATION

CONTACT TRIP

The common operating procedure on “Contact Trip” tools is for the operator to contact the

work to actuate the trip mechanism while keeping the trigger pulled, thus driving a fastener

each time the work is contacted. This will allow rapid fastener placement on many jobs,

such as sheathing, decking and pallet assembly.

All pneumatic tools are subject to recoil when driving fasteners. The tool may bounce,

releasing the trip, and if unintentionally allowed to recontact the work surface with the

trigger still actuated (finger still holding trigger pulled) an unwanted second fastener will be

driven.

SEQUENTIAL TRIP

The Sequential Trip requires the operator to hold the tool against the work before pulling

the trigger. This makes accurate fastener placement easier, for instance on framing, toe

nailing and crating applications.

The Sequential Trip allows exact fastener location without the possibility of driving a second

fastener on recoil, as described under “Contact Trip”.

The Sequential Trip Tool has a positive safety advantage because it will not accidentally

drive a fastener if the tool is contacted against the work – or anything else – while the

operator is holding the trigger pulled.

MODEL IDENTIFICATION:

Refer to Operation Instructions on page 7 before proceeding to use this tool.

AIR SUPPLY AND CONNECTIONS

Do not use oxygen, combustible gases, or bottled gases as a power

source for this tool as tool may explode, possibly causing injury.

FITTINGS:

Install a male plug on the tool which is free flowing and which will release air pressure

from the tool when disconnected from the supply source.

HOSES:

Air hoses should have a minimum of 150 p.s.i. (10.6 kg/cm2) working pressure rating or

150 percent of the maximum pressure that could be produced in the air system. The

supply hose should contain a fitting that will provide “quick disconnecting” from the male

plug on the tool.

SUPPLY SOURCE:

Use only clean regulated compressed air as a power source for this tool. NEVER USE

OXYGEN, COMBUSTIBLE GASES, OR BOTTLED GASES, AS A POWER SOURCE FOR

THIS TOOL AS TOOL MAY EXPLODE.

REGULATOR:

A pressure regulator with an operating pressure of 0 - 125 p.s.i. (0 - 8.79 KG/CM2) is

required to control the operatiing pressure for safe operation of this tool. Do not connect this

tool to air pressure which can potentially exceed 200 p.s.i. (14 KG/CM2)as tool may fracture or

burst, possibly causing injury.

OPERATING PRESSURE:

Do not exceed recommended maximum operating pressure as tool wear will be greatly

increased. The air supply must be capable of maintaining the operating pressure at the tool.

Pressure drops in the air supply can reduce the tool’s driving power. Refer to “TOOL SPECI-

FICATIONS” for setting the correct operating pressure for the tool.

FILTER:

Dirt and water in the air supply are major causes of wear in pneumatic tools. A filter will

help to get the best performance and minimum wear from the tool. The filter must have ade-

quate flow capacity for the specific installation. The filter has to be kept clean to be effective in

providing clean compressed air to the tool. Consult the manufacturer’s instructions on proper

maintenance of your filter. A dirty and clogged filter will cause a pressure drop which will

reduce the tool’s performance.

LUBRICATION

Frequent, but not excessive, lubrication is required for best performance. Oil added through the

air line connection will lubricate the internal parts. Use BOSTITCH Air Tool Lubricant, Mobil Velocite

#10, or equivalent. Do not use detergent oil or additives as these lubricants will cause accelerated

wear to the seals and bumpers in the tool, resulting in poor tool performance and frequent tool mainte-

nance.

If no airline lubricator is used, add oil during use into the air fitting on the tool once or twice a day.

Only a few drops of oil at a time is necessary. Too much oil will only collect inside the tool and will be

noticeable in the exhaust cycle.

COLD WEATHER OPERATION:

For cold weather operation, near and below freezing, the moisture in the air line may freeze and pre-

vent tool operation. We recommend the use of BOSTITCH WINTER FORMULA air tool lubricant or

permanent antifreeze (ethylene glycol) as a cold weather lubricant.

CAUTION: Do not store tools in a cold weather environment to prevent frost or ice formation

on the tools operating valves and mechanisms that could cause tool failure.

NOTE: Some commercial air line drying liquids are harmful to “O”-rings and seals – do not use

these low temperature air dryers without checking compatibility.

EYE PROTECTION which conforms to ANSI specifications and provides protec-

tion against flying particles both from the FRONT and SIDE should ALWAYS be

worn by the operator and others in the work area when loading, operating or ser-

vicing this tool. Eye protection is required to guard against flying fasteners and

debris, which could cause severe eye injury.

The employer and/or user must ensure that proper eye protection is worn. Eye

protection equipment must conform to the requirements of the American National

Standards Institute, ANSI Z87.1-1989 and provide both frontal and side protection.

NOTE: Non-side shielded spectacles and face shields alone do not provide ade-

quate protection.

TO PREVENT ACCIDENTAL INJURIES:

• Never place a hand or any other part of the body in nail discharge area of tool

while the air supply is connected.

• Never point the tool at anyone else.

• Never engage in horseplay.

• Never pull the trigger unless nose is directed at the work.

• Always handle the tool with care.

• Do not pull the trigger or depress the trip mechanism while loading the tool.

LOADING THE N95RHN

1.Open the magazine:

Pull pusher back to

engage latch.

2. Load Nails:

Hold nailer down with maga-

zine tilted downward. Insert

sticks of nails

3. Close Magazine:

Release latch by pulling latch tab

and pusher together slightly to

disengage, slide pusher against

nails.

NOTE: Use only All-Specs™ nails rec-

ommended for use in Bostitch N95RHN

series nailers or nails which meet the

Bostitch specifications.

FASTENER DEPTH CONTROL ADJUSTMENT

The Fastener Depth Control Adjustment feature provides control of the nail

drive depth from flush with or just above the work surface to shallow or deep

countersink.

TO ADJUST THE FASTENER DEPTH

CONTROL:

DISCONNECT TOOL FROM AIR SUPPLY BEFORE ATTEMPTING ANY

PARTS DISASSEMBLY AND BEFORE CHANGING THE WORK CON-

TACTING ELEMENT ADJUSTMENT.

1. With air pressure set, drive a few

fasteners into a representative

material sample to determine if

adjustment is necessary.

2. If adjustment is required, disconnect

air supply.

3. If adjustment to the drive depth is

required, measure the difference in

depth between the nail as driven in

the sample material and the desired

drive. The depth control should be

changed by the same amount. To

reduce the drive depth, the work

contacting element should be lengthened. To obtain a deeper drive, the

work contacting element should be shortened.

4.Note the level at which the depth control is assembled. Decide what

adjustment is required to achieve the length change determined in (2)

above. The dashes on the front of the depth control are evenly spaced

.08” (2mm). Zero would have the deepest countersink and 12 may leave

the nail head above the work. The tool is shipped from the factory on

setting “0”.

5.To make the adjustment, use a 10mm wrench or nut driver to loosen the

(2) elastic stop nuts on the depth control approximately 2 full revolutions.

It is not necessary to remove these nuts. Move the lower portion of the

depth control to the desired height and tighten the nuts. Do not

overtighten. Check that the work contacting element operates freely

without sticking or binding.

6.Reconnect air supply and drive a few fasteners in a sample of material to

determine if adjustment is correct. If further adjustment is necessary,

disconnect air and repeat above.

TOOL OPERATION

OPERATION

EYE PROTECTION which conforms to ANSI specifications and provides pro-

tection against flying particles both from the FRONT and SIDE should

ALWAYS be worn by the operator and others in the work area when loading,

operating or servicing this tool. Eye protection is required to guard against

flying fasteners and debris, which could cause severe eye injury.

The employer and/or user must ensure that proper eye protection is worn.

Eye protection equipment must conform to the requirements of the

American National Standards Institute, ANSI Z87.1-1989 and provide both

frontal and side protection. NOTE: Non-side shielded spectacles and face

shields alone do not provide adequate protection.

BEFORE HANDLING OR OPERATING THIS TOOL:

I. READ AND UNDERSTAND THE WARNINGS CONTAINED IN

THIS MANUAL.

II. REFER TO “TOOL SPECIFICATIONS” IN THIS MANUAL TO

IDENTIFY THE OPERATING SYSTEM ON YOUR TOOL.

1. CONTACT TRIP OPERATION

The CONTACT TRIP MODEL tool contains a contact trip that operates in conjunction with

the trigger to drive a fastener. There are two methods of operation to drive fasteners with

a contact trip tool.

A. SINGLE FASTENER PLACEMENT: To operate the tool in this manner, first

position the contact trip on the work surface, WITHOUT PULLING THE TRIGGER.

Depress the contact trip until the nose touches the work surface and then pull the

trigger to drive a fastener. Do not press the tool against the work with extra force.

Instead, allow the tool to recoil off the work surface to avoid a second unwanted

fastener. Remove your finger from the trigger after each operation.

B. RAPID FASTENER OPERATION: To operate the tool in this manner, hold the

tool with the contact trip pointing towards but not touching the work surface. Pull

the trigger and then tap the contact trip against the work surface using a bouncing

motion. Each depression of the contact trip will cause a fastener to be driven.

There are two available systems on BOSTITCH pneumatic tools. They are:

1. CONTACT TRIP OPERATION 2. SEQUENTIAL TRIP OPERATION

The operator must not hold the trigger pulled on contact trip tools

except during fastening operation, as serious injury could result if the

trip accidentally contacted someone or something, causing the tool to

cycle.

Keep hands and body away from the discharge area of the tool. A

contact trip tool may bounce from the recoil of driving a fastener and

an unwanted second fastener may be driven, possibly causing injury.

2. SEQUENTIAL TRIP OPERATION:

The SEQUENTIAL TRIP MODEL contains a contact trip that operates in conjunction

with the trigger to drive a fastener. To operate a sequential trip tool, first position the

contact trip on the work surface WITHOUT PULLING THE TRIGGER. Depress the

contact trip and then pull the trigger to drive a fastener. As long as the contact trip is

contacting the work and is held depressed, the tool will drive a fastener each time the

trigger is depressed. If the contact trip is allowed to leave the work surface, the

sequence described above must be repeated to drive another fastener.

MAINTAINING THE PNEUMATIC TOOL

When working on air tools, note the warnings in this manual and use extra care

evaluating problem tools.

CAUTION: Pusher spring (constant force spring). Caution must be used when working with

the spring assembly. The spring is wrapped around, but not attached to, a roller. If the spring

is extended beyond its length, the end will come off the roller and the spring will roll up with a

snap, with a chance of pinching your hand. Also the edges of the spring are very thin and

could cut. Care must also be taken to insure no permanent kinks are put in the spring as this

will reduce the springs force.

REPLACEMENT PARTS:

BOSTITCH replacement parts are recommended. Do not use modified parts or parts

which will not give equivalent performance to the original equipment.

ASSEMBLYPROCEDURE FOR SEALS:

When repairing a tool, make sure the internal parts are clean and lubricated. Use Parker “O”-LUBE

or equivalent on all “O”-rings. Coat each “O”-ring with “O”-LUBE before assembling. Use a small

amount of oil on all moving surfaces and pivots. After reassembly add a few drops of

BOSTITCH Air Tool Lubricant through the air line fitting before testing.

AIR SUPPLY-PRESSURE AND VOLUME:

Air volume is as important as air pressure. The air volume supplied to the tool may be inadequate

because of undersize fittings and hoses, or from the effects of dirt and water in the system.

Restricted air flow will prevent the tool from receiving an adequate volume of air, even though the

pressure reading is high. The results will be slow operation, misfeeds or reduced driving power.

Before evaluating tool problems for these symptoms, trace the air supply from the tool to the supply

source for restrictive connectors, swivel fittings, low points containing water and anything else that

would prevent full volume flow of air to the tool.
