Safety Yoke
A safety yoke mechanism on the nose of
the nailer/stapler acts as a safety device.
When the trigger is pressed, the nailer/
stapler will not fire until the safety yoke
mechanism is depressed.
Before you use your nailer/stapler for the
first time, check the safety yoke mecha-
nism to ensure proper function. To do
this:
1. DISCONNECT NAILER/STAPLER
FROM THE AIR SUPPLY!
2. Make sure the magazine is empty and
contains no nails/staples.
3. Make sure the trigger and the safety
yoke mechanism move up and down
without sticking.
4. Connect the nailer/stapler to the air
supply.
5. Without pressing 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 nailer/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.
The safety yoke is a mechanical
device that can fail. Never rely on the
safety yoke mechanism as an excuse
to point the nailer/stapler at yourself
or any bystanders. Serious injury may
occur.
