Safety Yoke
A safety yoke mechanism (bump fire) on
the nose of the stapler acts as a safety
device. When the trigger is pulled, the
stapler will not fire until the safety yoke
mechanism is depressed.
Before you use your stapler for the first
time, check the safety yoke mechanism to
ensure proper function. To do this:
1. DISCONNECT STAPLER FROM THE
AIR SUPPLY!
2. Make sure the magazine is empty and
contains no staples.
3. Make sure the trigger and the safety
yoke mechanism move up and down
without sticking.
4. Connect the stapler to the air supply.
5. Without pulling the trigger, depress
the safety yoke mechanism against a
scrap piece of wood that is clean and
free of any knots, nails, or other foreign
objects.
— If the stapler does not fire, then the
safety yoke mechanism is working
correctly.
— If the stapler does fire when you
do this, immediately disconnect the
stapler from the air supply and call
Grizzly Technical Support at (570)
546-9663 for help.
— If the stapler fires when the trig-
ger is pulled, without the safety
yoke mechanism being depressed,
disconnect the stapler from the air
supply and call Grizzly Technical
Support at (570) 546-9663 for help.
— If the stapler is not working properly,
check the lubrication of the sliding
mechanisms of the safety yoke, and
immediately discontinue using the
stapler.
The safety yoke is a mechanical
device that can fail. Never rely on the
safety yoke mechanism as an excuse
to point the stapler at yourself or any
bystanders. Serious injury may occur.
