Testing the Safety
Nose Mechanism
A safety mechanism (bump fire) on the
nose of the nailer protects against acci-
dental firing. When the trigger is pressed,
the nailer will not fire until the safety nose
mechanism is depressed.
Before you use your nailer for the first
time, check the safety nose mechanism
to ensure proper function.
5. Without pressing the trigger, depress
the safety nose 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 nose mechanism is working
correctly.
— If the nailer does fire when you
depress the safety nose, immedi-
ately disconnect the nailer from the
air supply and call Grizzly Technical
Support at (570) 546-9663 for help.
6. Without depressing the safety nose,
point the nailer in a safe direction, and
pull the trigger.
— If the nailer does not fire, then the
safety nose mechanism is working
correctly.
— If the nailer does fire when the trig-
ger is pulled, without the safety nose
mechanism being depressed, then
the nailer has been damaged. For
help, call Grizzly Technical Support
at (570) 546-9663 for help.
The safety mechanism is a mechanical
device that can fail. Never rely on this
mechanism as an excuse to point the
nailer at yourself or any bystanders.
Serious injury may occur.
To verify that the safety nose is working
correctly:
1. DISCONNECT NAILER FROM THE
AIR SUPPLY!
2. Make sure the magazine contains no
nails.
3. Make sure the trigger and the safety
nose mechanism move up and down
without sticking.
4. Connect the nailer to the air supply.
