TOOL OPERATION (CONTINUED)
3. 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.
Converting this tool to conventional CONTACT TRIP requires DISABLING the SMART
TRIGGER and its ANTI-DOUBLE FIRE REDUCTION FEATURE. You MUST advise ANY
USER of this tool that SMART TRIGGER has been disabled.
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.
Never use smart trigger or contact trigger (black trigger) with metal connector attachment.
Only use sequential trigger (gray trigger) with metal connector attachment. Refer to trigger
conversion instruction included in the kit.
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.
