For Your Own Safety Read Instruction Manual
Before Operating This Equipment
The purpose of safety symbols is to attract your attention to possible hazard-
ous conditions. This manual uses a series of symbols and signal words which
are intended to convey the level of importance of the safety messages. The
progression of symbols is described below. Remember that safety messages by
themselves do not eliminate danger and are not a substitute for proper accident
prevention measures.
Indicates an imminent hazardous situation which, if
not avoided, WILL result in death or serious injury.
Indicates a potentially hazardous situation which, if
not avoided, COULD result in death or serious injury.
Indicates a potentially hazardous situation which, if
not avoided, MAY result in minor or moderate injury.
It may also be used to alert against unsafe practices.
This symbol is used to alert the user to useful infor-
mation about proper operation of the equipment.

this filter/lubricator/regulator unit will
protect your tool from damaging water
build-up, allow you to adjust and maintain
constant air pressure to your tool, and
save you the inconvenience of having to
manually lubricate your tool every time
you use it.
compressed air
system
the Model t26416 is designed to be oper-
ated at 70-120 psi using clean, dry, regu-
lated, compressed air. do not exceed
the 120 psi maximum operating pres-
sure for your model.
Check the current grizzly catalog for avail-
ability of this unit. if you plan on install-
ing a filter/lubricator/regulator unit in your
compressed air system, always follow the
connection instructions that come with
the unit.
Before using your new stapler, regulate the
air pressure on your air compressor to the
minimum psi for your model.
an in-line filter/lubricator/regulator unit,
depicted in figure 5, can be installed and
should be located as close to the stapler
as possible.

test run
6. inspect scrap piece to ensure staple
was driven correctly.
prior to using the stapler for regular opera-
tions, perform this test run procedure on
a scrap workpiece at least 11⁄2" thick to
ensure it functions properly.
7. as a one time test of the safety mecha-
nism, pull the stapler back from the
scrap piece until the safety probe is no
longer depressed. angle the stapler so
the ricochet trajectory is away from you
and others, then pull the trigger.
to test run stapler:
1. insert staples into stapler, following
directions in loading staples section.
— if the stapler did not fire then the
safety mechanism is working cor-
rectly.
2. Firmly holding stapler with nose point-
ing away from you and others, connect
stapler to air supply.
— if the stapler did fire, the safety
mechanism is not working correctly.
Carefully disconnect the air supply
and contact tech support to resolve
the problem before using the stapler
any further.
3. Clamp the scrap workpiece to a work-
station.
4. press the stapler against the scrap
workpiece and fully depress the safety
probe (see figure 6).

the purpose of this overview is to pro-
vide the novice tool operator with a basic
understanding of how the tool is used.
to perform a typical operation:
1. disConnECt staplEr FroM air
supply!
2. Check to ensure there are enough
staples in the magazine and reconnect
to air supply.

Wear safety glasses when using
this tool.
3. drive a staple into a scrap piece of the
same material, and inspect the depth of
the driven staple.

Wear protective
equipment when
using this tool.
if the staple was not driven in the cor-
rect depth, use the depth adjustment
wheel to properly set the staple depth
(see figure 7). rotating the wheel
clockwise (from the backside) increas-
es the depth, while rotating counter-
clockwise decreases the depth.

4. align workpieces to be stapled.
5. place safety probe 1⁄8" above the staple
insertion target, and push down the sta-
pler until it is butted up against and per-
pendicular with the bottom workpiece.
6. Before pulling the trigger, make sure
your free hand and other body parts
are out of staple trajectory or deflection
paths.
deflection due to material irregulari-
ties can cause puncture injuries to
improperly placed hands or body
parts. always position hands and
body away from staple trajectory
and deflection paths.

section 6: maintenance
cleaning
lubricating
disconnect the stapler from the air supply
before cleaning. use a good solvent to
clean the nose assembly of the stapler.
always be sure that the stapler is dry
before using it again.
place two to six drops of pneumatic tool oil
in the nailer air inlet (as shown in figure
11) every 2 hours of continuous use. Wipe
off any excess oil near the nailer exhaust
to avoid dust build-up.
do not allow dust, chips, sand, etc. into the
air connectors or into the body of the sta-
pler; this may result in leaks and damage
to the stapler and the air couplings.
figure 11. lubricating stapler via air inlet.
another option to manual oiling would be
to simply install a lubricator in your air
compressor line. if your air compressor
line already has a lubricator, then regular
lubrication of your nailer will not be neces-
sary. Just make sure there is always oil in
the lubricator.
never use gasoline or other flamma-
ble liquids to clean this tool. vapors
in the tool may ignite, causing the
tool to explode. ignoring this warning
may lead to serious personal injury
or even death!

section 7: service
6. Being careful not to scratch the sides of
the driver guide, insert a slim and stur-
dy piece of metal through the hole at
the top of the magazine compartment
(see figure 12), and push the piston
assembly out the back of the cylinder.

replacing o-rings &
piston assemblies
7. place a thin film of the stapler lubri-
cating oil on the o-ring of the piston
assembly.
if you use your stapler frequently,
replacement piston assemblies (part
pt26416112a) and o-ring kits (part
pt26416428) are cheap insurance against
wasted down time and lost profits, in
the event that the piston assembly or an
o-ring becomes worn out.
8. insert the new piston assembly into
the cylinder. Make sure that the end
of the driver on the piston assembly
lines up with the slit at the bottom of
the cylinder. the new piston assembly
should easily slide into the cylinder.
do not force the piston assembly
into the cylinder! if it is not easily
inserted, double-check the alignment of
the driver end with the slit.
to replace piston assembly:
1. disConnECt staplEr FroM air
supply!
9. after the piston assembly is inserted
correctly, close the magazine pusher.
replace the cylinder cap assembly and
tighten the 4 cap screws.
2. remove all staples from the magazine
cartridge.
3. remove the four cap screws on the
cylinder cap of the stapler, near the
exhaust port.
10. For more assistance, or to install a
complete o-ring set, refer to the appro-
priate breakdown diagram in the back
of this manual for component locations.
4. remove the cap.
5. pull back the pusher revealing the
magazine compartment.
