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 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
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.
LOADINGTOOL

Operating Pressure:
70 to 120 p.s.i.g. (4.9 to 8.43 kg/cm2). Select the operating pressure within in this range for best fastener performance.
DO NOT EXCEED THIS RECOMMENDED OPERATING PRESSURE.
Air Consumption:
The FN1664 requires 3.9 cubic feet per minute or C.F.M. (110.4 liters per minute or LT/MIN) of free air at 80PSI (5.6 kg/cm2) to operate at a rate of 60 fasteners per minute. To determine the appropriately sized air compressor, take the actual rate at which the tool will be run and compare the required C.F.M. (LT/MIN) to the compressors free air delivery (C.F.M./ LT/MIN) at 80 PSI (5.6 kg/cm2).
For example, if your fastener usage averages 30 fasteners per minute, you need 50% of the tools C.F.M. required to operate the tool at the rate of 60 fasteners per minute. In this case, be sure that your air compressor can deliver a minimum of 1.90 C.F.M. (55.2 LT/MIN) at 80 PSI(5.6 kg/cm2) for optimum performance.

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 sourcefor this tool. NEVER USE OXYGEN, COMBUSTIBLE GASES, OR BOTTLED GASES,AS A POWER SOURCE FOR THIS TOOL AS TOOL MAYEXPLODE.
REGULATOR:
A pressure regulator with an operating pressure of 0 - 125 p.s.i. (0 - 8.79 kg/cm2) 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. (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.

TRIP OPERATION MODE
Warning: Always disconnect air supply before making adjustments as accidental actuation may occur, possibly causing injury.
The FN1664 features a selectable trigger system that allows the user to choose between the following modes of operation:
1. Contact TripOperation |
2. Sequential Trip Operation |
1. CONTACTTRIP:
The common operation procedure on “Contact Trip” tools is for the operator to contact the work surface to actuate the trip mechanism while keeping the trigger pulled, thus driving a fastener each time the work surface is contacted. This will allow rapid fastener placement on many jobs. 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 the trigger pulled) an unwanted second fastener will be driven.
2. 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. The Sequential Trip allows exact fastener location without the possibility if driving a second fastener on recoil as described under “Contact Trip”. The Sequential Trip Tool has a positive advantage because it will not accidentally drive a fastener if the tool is contacted against the work surface - or anything else - while the operator is holding the trigger pulled.
SELECTING THE TRIP MODE:
To ensure safety, the user must lock the trigger (as described above) before changing the trigger system. To change the trip mode, rotate the mode switch in the counterclockwise direction. The mode switch will lock automatically when the indicating arrow is pointing down to the 3 nail icon stamped into the tool frame (Contact Trip Mode) or to a single nail icon stamped in the tool frame( Sequential Trip Mode). Unlock the trigger to resume tool operation.

TOOL OPERATION
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 Z87.1and 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 MANUALTO IDENTIFY THE OPERATING SYSTEM ON YOURTOOL.
OPERATION
1. CONTACT TRIP OPERATION:
In CONTACT TRIP MODE the 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.
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. SEQUENTIALTRIP OPERATION:
In SEQUENTIAL TRIP MODE the contact trip operates in conjunction with the trigger to drive a fastener. Tooperate 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.

JAM CLEARING PROCEDURE
Disconnect tool from air supply before making adjustments or before attempting any part assembly or disassembly.
On occasion nails can jam in the nose of a pneumatic nailer. This can be caused by striking a metal plate in the wall, drywall screw, or some other hard object. The FN1664 feature open drive channel architecture for jam clearing. To clear a jam follow this procedure:
1.Disconnect the tool from the air supply.
2.Release the pusher so it is no longer applying force to the nail sticks.
3.Open the jam clearing nose door by pulling down and then up on the latch.
4.Remove the jammed fastener. In certain circumstances, pliers may be required to remove the fastener.
5.Close the jam clearing nose door latch.
6.Pull nail pusher back behind nail sticks.

MAINTAININGTHE PNEUMATICTOOL
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:
Use only genuine BOSTITCH replacement parts. Do not use modified parts.
ASSEMBLY PROCEDURE FOR SEALS:
When repairing a tool, make sure the internal parts are clean and lubricated. Use Parker “O”-LUBE, Magnalube, or equivalent on all “O”-rings. Coat each “O”-ring with lubricant before assembling.
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, low points containing water and anything else that would prevent full volume flow of air to the tool.
