Safety Yoke Mechanism
The safety yoke is a mechanical
device that can fail. Never rely on the
safety yoke mechanism as an excuse
to point the stapler at yourself or any
bystanders. Serious injury may occur.
Exceeding the maximum permissible
operating pressure may cause the sta-
pler to explode, blowing metal frag-
ments in all directions. To protect
yourself from serious personal injury,
DO NOT allow your air compressor to
exceed the recommended pressure
when connected to this stapler!
The Model H2909 is designed to be oper-
ated at 60-100 psi.
Do not exceed the
maximum operating pressure for your
model.
Before you use your new stapler, install the
3
⁄
8
" quick connect fitting that comes with the
stapler. Install a female
3
⁄
8
" fitting on the air
hose. Regulate the air pressure on your air
compressor to barely over the minimum psi
for your model.
Many pneumatic tools benefit from an in-
line filter/lubricator/regulator unit. This
attachment is connected by hoses
between the air compressor and the sta-
pler. Using this unit protects your tool from
damaging water build-up, allows you to
adjust and maintain constant air pressure
to your tool, and saves you the inconve-
nience of having to manually lubricate your
tool every time you use it. Check the cur-
rent Grizzly catalog for availability of this
unit. If you plan on installing a filter/lubrica-
tor/regulator unit in your compressed air
system, always follow the connection
instructions that come with the unit.
A safety yoke mechanism (bump fire) on
the nose of the stapler acts as a secondary
safety device. When the trigger is pressed,
the stapler will not fire until the safety yoke
mechanism is depressed.
Before you use your stapler for the first
time, check the safety yoke mechanism to
ensure proper function. To do this:
1.
Make sure the stapler is discon-
nected from the air supply!
2.
Make sure the magazine is empty and
contains no staples.
3.
Make sure the trigger and the safety
yoke mechanism move up and down
without sticking.
4.
Connect the 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, staples,
or other foreign objects. If the 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 our cus-
tomer service for help.
Similarly if the stapler fires when the trigger
is pulled,
without the safety yoke mech-
anism being depressed
, then the stapler
is not working properly.
If either of these two conditions develop
after you have used your stapler for a peri-
od of time, check the lubrication of these
mechanisms.
