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 and provide both frontal and side protection. NOTE: Non-side shielded spectacles and face shields alone do not provide adequate protection.

CAUTION:

ADDITIONAL SAFETY PROTECTION will be required in some environments. 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 disconnected. If a wrong fitting is used, the tool can remain charged with air after disconnecting and thus will be able to drive a fastener even after the air line is disconnected 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 discharge 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 distance 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 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 arm tool may bounce from the recoil of driving a fastener and an unwanted second fastener 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.

Do not use the contact trip (black trigger) when installing metal connectors. Do not use the tool to install metal connectors without the Metal Connector Attachment installed.

MAINTAINING THE TOOL

When working on air tools note the warnings in this manual and use extra care when evaluating problem tools.

N88RH-2MCN TOOL SPECIFICATIONS

All screws and nuts are metric.

FASTENER SPECIFICATIONS:

N88RH-2MCN (with standard framing contact arm installed)

Uses a 21° plastic collated full round head stick nails, in lengths of 2” to 3-1/2” (50-90mm) and shank diameters of .113” to .162” (2.8 - 4.1mm)

N88RH-2MCN (with metal connector attachment installed)

Uses a 21° plastic collated full round head metal connector nails, in lengths of 1 1/2” and 2-1/2” (38 - 64mm) and shank diameters of .131”, .148” and .162”.

Use only one stick of metal connector nails at a time.

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.

OPERATING PRESSURE:

70 to 120 p.s.i.g. (4.9 to 8.4 kg/cm2). Select the operating pressure within this range for best fastener performance. DO NOT EXCEED THIS RECOMMENDED OPERATING PRESSURE.

AIR CONSUMPTION:

The N88RH-2MCN requires 7.5 cubic feet per minute (212 liters per minute) of free air to operate at the rate of 100 nails per minute, at 80 p.s.i. (5.6 kg/cm

). Take the actual rate at which the tool will be run to determine the amount of air required. For instance, if your fastener usage averages 50 nails per minute, you need 50% of the 7.5 c.f.m. (212 liters per minute) which is required to operate the tool at 100 nails per minute.

OPERATION

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.

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.

SUPPL

Y 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 SPECIFICATIONS” 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 adequate 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 maintenance.

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 WEA

THER OPERATION:

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

Used properly, the tool provides an easy, safe, and efficient method for driving nails for all kinds of construction projects. NOTE: Refer to your Operation Manual or Parts List if any of the terms used below are unfamiliar to you.

SEQUENTIAL TRIP

Your new Bostitch tool with the Sequential Trip (gray trigger):

1. Offers a positive safety advantage since it will not accidentally drive a nail if the tool is bumped against any surface or anybody while the operator is holding the tool with the trigger pulled.

2. Allows Place Nailinq without the possibility of driving a second nail on recoil. The Sequential Trip (gray trigger) gets its name from the "sequence" required to operate the tool. To drive a nail, the operator must first depress the trip against the work and then pull the trigger. To drive a second nail, the operator must lift the tool from the work, release the trigger, and then repeat the above sequence.

TO AVOID SERIOUS INJURY FROM FASTENERS AND FLYING DEBRIS WHEN INSTALLING METAL CONNECTORS WITH THE N88RH-2MCN:

• Always use the Metal Connector Attachment. (see installation instructions).

• Only use sequential trip(gray trigger).

• Use only genuine Bostitch metal connector nails.

• Use only one stick of metal connector nails at a time.

• Metal connector nails are not designed to penetrate metal. When installing metal connectors, always place the Metal Connector Attachment Guide in the metal connector’s preformed hole before attempting to drive a fastener

TOOL OPERATION

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.

OPERATION

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 THETRIGGER. 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, as is typical with normal tool recoil, the sequence described above must be repeated to drive another fastener.

TOOL OPERATION CHECK:

CAUTION: Remove all fasteners from tool before performing tool operation check.

SEQUENTIAL TRIP OPERATION: ( N88RH-2MCN)

A. Press the contact trip against the work surface, without touching the trigger.

THE TOOL MUST NOT CYCLE.

B. Hold the tool off the work surface and pull the trigger.

THE TOOL MUST NOT CYCLE.

Release the trigger. The trigger must return to the trigger stop on the frame.

C. Pull the trigger and press the contact trip against the work surface.

THE TOOL MUST NOT CYCLE.

D. With finger off the trigger, press the contact trip against the work surface. Pull

the trigger.

THE TOOL MUST CYCLE.

IN ADDITION TO THE OTHER WARNINGS CONTAINED IN THIS MANUAL OBSERVE THE

FOLLOWING FOR SAFE OPERATION

• Use the BOSTITCH pneumatic tool only for the purpose for which it was designed.

• Never use this tool in a manner that could cause a fastener to be directed toward the user or

others in the work area.

• Do not use the tool as a hammer.

• Always carry the tool by the handle. Never carry the tool by the air hose.

• Do not alter or modify this tool from the original design or function without approval from

BOSTITCH, INC.

• Always be aware that misuse and improper handling of this tool can cause injury to yourself and

others.

• Never clamp or tape the trigger or contact trip in an actuated position.

• Never leave a tool unattended with the air hose attached.

• Do not operate this tool if it does not contain a legible WARNING LABEL.

• Do not continue to use a tool that leaks air or does not function properly. Notify your nearest

Bostitch representative if your tool continues to experience functional problems.

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 P

ARTS:

BOSTITCH replacement parts are recommended. Do not use modified parts or parts which will not give equivalent performance to the original equipment.

ASSEMBL Y PROCEDURE FOR SEALS:

When repairing a tool, make sure the internal parts are clean and lubricated. Use MagnaLube or equivalent on all “O”-rings. Coat each “O”-ring with lubricant 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.
