Safety Yoke
A safety yoke mechanism on the nose
of the nailer acts as a secondary safety
device. When the trigger is pressed, the
nailer will not fire until the safety yoke
mechanism is depressed.
Before you use your nailer for the first
time, check the safety yoke mechanism to
ensure proper function. To do this:
1. DISCONNECT NAILER FROM THE
AIR SUPPLY!
2. Make sure the magazine is empty and
contains no nails.
3. Make sure the trigger and the safety
yoke mechanism move up and down
without sticking.
4. Connect the nailer 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 does not fire, then the
safety yoke mechanism is working
correctly.
— If the nailer does fire when you
do this, immediately disconnect the
nailer from the air supply and call
Grizzly Technical Support at (570)
546-9663 for help.
— If the nailer fires when the trigger
is pulled without the safety yoke
mechanism being depressed, then
the nailer is not working properly.
— If either of these conditions develop
after you have used your nailer for a
period of time, check the lubrication
of these mechanisms.
The safety yoke is a mechanical
device that can fail. Never rely on the
safety yoke mechanism as an excuse
to point the nailer at yourself or any
bystanders. Serious injury may occur.
