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 Z87.1/CAN/CSA Z94.3 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.
There are two available operation modes on these BOSTITCH pneumatic tools. They are:
1. SEQUENTIAL TRIP OPERATION
2. CONTACT TRIP OPERATION
BOSTITCH offers two types of operating modes which function differently: Sequential Trip and Contact Trip.
Each mode has specific advantages. You should evaluate your particular construction project to determine
which mode is best.
Your tool was shipped from the factory in the Sequential Trip configuration. It can easily be converted to the
Contact Trip mode of operation using this Contact Trip conversion kit. Refer to “To Change Operating Modes”
to change between Sequential Trip and Contact Trip modes.
Always verify and be aware of tool operating mode by inspecting the trigger before
connecting to an air supply and/or using the tool.
1. SEQUENTIAL TRIP OPERATION:
The Sequential Trip (Mode) gets its name from the “sequence” required to drive a fastener. To drive a fastener,
the operator must first depress the “trip” FULLY against the work surface and then pull the trigger. To drive a
second nail, the operator must lift the tool from the work surface, release the trigger and then repeat the above
sequence.
A. The Sequential Trip (Mode): offers a positive safety advantage since it will not
accidentally drive a fastener if the tool is bumped against any surface or anybody
while the operator is holding the tools with the trigger pulled.
B. The Sequential Trip (Mode): allows “place nailing” without the possibility of driving
a second, unwanted fastener on recoil as described below under “Contact Trip”.
2. CONTACT TRIP OPERATION:
Be aware that once the mode locking pin is removed, the trigger is converted to a
selectable trigger, enabling both contact trip and sequential trip operating modes.
Your new BOSTITCH tool can be configured for use in Contact Trip “Conventional trip” mode. To drive a nail, the
“trip” and the trigger must both be depressed. In conventional Contact Trip tools, the trigger may be depressed
and held, and each “contact” between the trip and the work surface will drive a nail.
A. SINGLE FASTENER PLACEMENT (Place Nailing) – First position the “trip”
FULLY on the work surface, WITHOUT PULLING THE TRIGGER. Depress the “trip”
FULLY until the nose of the tool touches the work surface and then pull the trigger
to drive a nail. Do not press the tool against the work surface with extra force.
Instead, allow the tool to recoil off the work surface to avoid a second unwanted
fastener. Note: remove your finger from the trigger after each operation.
B. RAPID FIRE OPERATION (“Bump” Nailing) – First, hold the tool with the “trip” pointing towards but not
touching the work surface. Pull the trigger and then tap or “bump” the trip against the work surface using
a bouncing motion. Each depression of the “trip” will cause a nail to be driven.
The Contact Trip will not prevent a nail from being accidentally driven if the trigger is
depressed and the “trip” is bumped against any object or person. Never hold or carry
the tool with your finger on the trigger. Only depress and hold trigger when you intend to
rapidly drive multiple nails and the tool is pointed at the work surface.
When using conventional Contact Trip for Place Nailing, the tool may bounce due to
recoil, and if the tool is allowed to re-contact the work surface while you are holding the
trigger pulled, a second unwanted nail will be driven. You should allow the tool to recoil
far enough to release the trip and avoid a second cycle. Don’t push the tool down extra
hard; let the tool do the work.
