Model W1781 21˚ Framing Nailer
Safety Nose Mechanism
A safety mechanism on the nose of
the nailer protects against accidental
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.
To check the safety nose mechanism,
do these steps:
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
nose mechanism move up and down
without sticking.
4. Connect the nailer to the air supply.
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 do
this, immediately disconnect the
nailer from the air supply and call
Technical Support.
— If you find that the safety
nose mechanism is not working
properly, check the lubrication of
its sliding components.
— If the nailer fires when the trigger
is pulled, without the safety nose
mechanism being depressed, then
the nailer is not working properly.
Do not attempt to modify or bypass
the safety nose mechanism to make
the nailer fire without pushing the
nose down.
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.
Operating this nailer can propel
objects into the air, causing immediate
eye damage. To protect yourself,
always wear ANSI approved safety
glasses or goggles when operating this
equipment.
