IMPORTANT – READ CAREFULLY
You and others working around
you can be seriously injured by fastener driving tools if you do not
follow the instructions provided on the tool and in the operations
manual. Used properly, these tools provide easy, safe, and efficient
methods for driving nails and staples and closing rings and clips.

Bostitch offers two types of
triggers for pneumatic tools: Contact Trip (black trigger) and
Sequential Trip (silver-gray trigger). However, some of our fastening
tools come with a Trigger Only or an Auto Fire feature. Each trigger
has specific advantages. For example, the Contact Trip is best suited
for high volume rapid nailing or stapling where exact placement of the
fastener is not important. The Sequential Trip is best suited for
applications where rapid nailing is not required or where the exact
placement of the fasteners is important. The Trigger only operation can
be used where the work piece contact is not practical because of the
specific operation performed by the fastener driving tool. The Auto
Fire trigger can be used in applications where multiple fasteners need
to be placed as quickly as possible. Your application should be
evaluated to determine which trigger is best.
A Bostitch tool with
the Contact Trip (black trigger) installed will drive a nail whenever
both the trip and the trigger are depressed at the same time.
The tool can be used to
rapidly drive nails by holding the trigger pulled and repeatedly bumping
the trip against the work to be nailed (Bump Nailing). A nail is driven
each time the trip is bumped against the work.
The Contact Trip (black
trigger) will not prevent a nail from being accidentally driven if the
trigger is held, pulled and the trip is bumped against any object or
person. Never hold or carry the tool with your finger on the trigger
unless driving fasteners.
The Contact Trip (black
trigger) can also be operated by holding the tool against the work with
the trip depressed and then pulling the trigger (Place Nailing).
When using a 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 nail will be driven. The operator 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 Sequential Trip
(silver-gray trigger) offers a positive safety advantage since it will
not accidentally drive a nail if the tool is bumped against any surface
or anybody while the operator is holding the tool with the trigger
It also allows Place Nailing
without the possibility of driving a second nail on recoil as described
under “Contact Trip”.
The Sequential Trip
(silver-gray trigger) gets its name from the “sequence” required to
operate the tool. To drive a nail, the operator must first depress the
trip against the work and then pull the trigger. To drive a second
nail, the operator must lift the tool from the work, release the
trigger, and then repeat the above sequence.
TRIGGER OPERATED TRIP
Trigger operated tools are
operated by trigger alone and are intended for use only where a
sequential or contract trip cannot be used. Tool operation by Trigger
Only is used on some tools which can drive only small fasteners.
Trigger Only operation is also available on some larger models for use
where the contact arm – “work piece contact” – is not practical because
of the specific operations performed by the fastener driving tool.
Some small staplers come with
an Auto Fire feature. Some applications such as attaching fabric to
wood require multiple staples to be applied quickly as possible, the
operator makes contact with the work piece, depresses the trigger and
moves the tool across the piece. The tool will fire staples as long as
the trigger is depressed. Care must be taken to only activate the
trigger when tool nose is in contact with the work piece.
