Bostitch offers two types of operating modes which function differently: Sequential Trip and Contact Trip. Each
ode 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 “How to Change Operating
odes” 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:
he 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.
o drive a second nail, the operator must lift the tool from the work surface, release the trigger and then
repeat the above sequence.
. 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
he operator is holding the tools with the trigger pulled.
2. 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.
TOOL OPERATION (CONTINUED)
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.
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.
Never use utility hook to hang tool from body, clothing or belt.
