Testing Safety Nose
Mechanism
A safety mechanism (bump fire) on the
nose of the nailer protects against acci-
dental firing. This mechanism is activated
when nails are loaded into the magazine.
The nailer will not fire when the trigger
is pulled until the safety nose is fully
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
trigger is pulled, without the safety
nose mechanism being depressed,
immediately disconnect the nailer
from the air supply and 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. Insert a coil of nails in the magazine
(see Page 8 for instructions).
3. Make sure the trigger and the safety
nose mechanism move up and down
without sticking.
4. Connect the nailer to the air supply.
Point the nailer away from you and
others when connecting the air supply.
The nailer can cycle and discharge a
nail when the air supply is connected.
Ignoring this warning may result in
serious personal injury.
