SAFETY INSTRUCTIONS

Warning

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 connecting to air supply, 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 is used.

AIR SUPPLY AND CONNECTIONS

Warning

• 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

Warning

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

Warning

• 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.
• This nailer produces SPARKS during operation. NEVER use the nailer near flammable substances, gases or vapors including lacquer, paint, benzine, thinner, gasoline, adhesives, mastics, glues or any other material that is — or the vapors, fumes or byproducts of which are –flammable, combustible or explosive. Using the nailer in any such environment could cause an EXPLOSION resulting in personal injury or death to user and bystanders.

TOOL AIR FITTING

This tool uses a free-flow connector plug, 1/4” N.P.T. The inside diameter should be .200” (5mm) or larger. The fitting must be capable of discharging tool air pressure when disconnected from the air supply.

OPERATING PRESSURE

70 to 100 p.s.i.g. (4.8 to 6.9 bar). Select the operating pressure within this range for best fastener performance.
DO NOT EXCEED THE RECOMMENDED OPERATING PRESSURE.

AIR CONSUMPTION

The 216 requires 1.71 cubic feet per minute (.048 cubic meters) and the 216-LN models require 1.84 cubic feet per minute (.052 cubic meters) of free air to operate at the rate of 100 nails per minute, at 80 p.s.i. (5.5 bar). 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 tool’s c.f.m. which is required to operate the tool at 100 nails per minute.

AIR SUPPLY AND CONNECTIONS

Warning

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. (10.34 bar) 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 – 8.6 bar) is required to control the operating pressure for safe operation of this tool. Do not connect this tool to air pressure which can potentially exceed 200 p.s.i. (13.8 bar) 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.

LOADING THE 216

TOOL OPERATION

BEFORE HANDLING OR OPERATING THIS TOOL:

1. READ AND UNDERSTAND THE WARNINGS CONTAINED IN THIS MANUAL.
2. REFER TO “TOOL SPECIFICATIONS” IN THIS MANUAL TO IDENTIFY THE OPERATING SYSTEM ON YOUR TOOL.

BOSTITCH offers two types of Operation for the 216 series tools.

MODEL IDENTIFICATION

Refer to Tool Operation Check on page 9 before proceeding to use this tool.

Trigger Operated

The Trigger Operated model is cycled by actuation of the trigger.
The Trigger Operated tool will cycle each time the trigger is actuated.

Automatic

The automatic model is cycled by actuation of the trigger. When the trigger is pulled lightly with a short motion the tool will drive one fastener. When the trigger is pulled as far as possible the tool will continuously drive fasteners automatically until the trigger is released. The rate at which fasteners are driven in the automatic mode is adjustable. The speed adjustment screw is located on the left side of the tool in the trigger valve area. Turning the screw in a counter clockwise direction increases speed and in a clockwise direction decreases speed. This model also includes a trigger free play adjustment to adjust the amount of trigger stroke between single and automatic operation. Turning the adjustment knob to the left increases the trigger travel from single actuation to automatic.

POWER ADJUSTMENT VALVE

For Maximum Power: Rotate valve counterclockwise as far as possible.
To Reduce Power: Rotate valve clockwise for up to 30% reduction.

TOOL OPERATION CHECK

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

MAINTAINING THE PNEUMATIC TOOL

Warning

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

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

Assembly 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 MAGNALUBE before assembling. Use a small amount of oil on all moving surfaces and pivots.

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.

Trigger Valve Removal:

• Automatic
  • 1. Remove trigger pivot pin.
  • 2. Remove trigger.
  • 3. To remove trigger free play adjustment housing pull in direction of arrow until it is clear of valve.
  • 4. Remove two trigger valve pins and remove trigger valve.
• Standard Valve
  Remove two trigger valve pins (item 4) and remove trigger valve.
