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 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 BOSTITCH pneumatic tools. They are:
1. SEQUENTIAL TRIP OPERATION 2. CONTACT TRIP OPERATION
OPERATION
BOSTITCH offers two types of triggers which can operate in one of two ways for pneumatic tools: Sequential
Trip (gray trigger) and Contact Trip (black trigger). Each trigger has specific advantages. You should evaluate
your particular construction project to determine which trigger is best.
Your tool was shipped from the factory in the Sequential Trip (gray trigger) configuration. It can easily be
converted to the Contact Trip (black trigger) mode of operation.
1. SEQUENTIAL TRIP OPERATION (GRAY TRIGGER):
The Sequential Trip (gray trigger) 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.
1. The Sequential Trip (gray trigger):
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.
2. The Sequential Trip (gray trigger):
allows “place nailing” without the possibility of driving a second,
unwanted fastener on recoil as described below under “Contact Trip”.
2. CONTACT TRIP (CONVENTIONAL) OPERATION (BLACK TRIGGER):
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 (black) 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.
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.
