H5570 18 Gauge Finish Angle Nailer
-5-
Compressed Air System 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 nailer at yourself or any
bystanders. Serious injury may occur.
Exceeding the maximum permissible
operating pressure may cause the
nailer 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 nailer!
The Model H5570 is designed to be oper-
ated at 70-100 psi. DO NOT exceed the
maximum operating pressure for your
model.
Before using your new nailer, install the
included
1
⁄4" NPT male quick connect fitting
on the nailer and a
1
⁄4" NPT female 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. 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 inconvenience of having
to manually lubricate your tool every time
you use it. Check the current Grizzly cata-
log for availability of this unit. If you plan on
installing a filter/lubricator/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 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. Make sure the nailer is disconnect-
ed 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 our cus-
tomer service for help.
Similarly if the nailer fires when the trigger
is pulled, without the safety yoke mecha-
nism being depressed, then the nailer is
not working properly.
If either of these two conditions develop
after you have used your nailer for a peri-
od of time, check the lubrication of these
mechanisms.
