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 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 (R1998) 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
There are two available systems on BOSTITCH N88 pneumatic tools. They are:
1. CONTACT TRIP OPERATION 2. SEQUENTIAL TRIP OPERATION
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.
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, as is
typical with normal tool recoil, the sequence described above must be repeated to drive another fastener.
