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.
NOTICE

Model T27338 (Mfd. Since 01/15)-2-
USE PROPER AIR HOSE for the tool.
Make sure your air hose is in good condi-
tion and is long enough to reach your work
area without stretching.
WEAR PROPER APPAREL. Do not wear
loose clothing, gloves, neckties, rings,
bracelets, or other jewelry which may get
caught in moving parts. Non-slip footwear
is recommended. Wear a protective hair
covering to contain long hair.
ALWAYS USE SAFETY GLASSES. Also
use a face or dust mask if operation is
dusty. Everyday eyeglasses only have
impact resistant lenses, they are NOT
safety glasses.
WEAR APPROVED HEARING
PROTECTION. Air escaping from pneu-
matic tools can exceed safe exposure
limits and may cause hearing damage
with prolonged exposure.
AWKWARD POSITIONS. Keep proper
footing and balance at all times when
operating tool. Do not overreach! Avoid
awkward hand positions that make work-
piece control difficult or increase the risk
of accidental injury.
REDUCE THE RISK OF
UNINTENTIONAL FIRING. Do not carry
tool with hand on trigger and always dis-
connect from air when not in use.
CHECK FOR DAMAGED PARTS.
Regularly inspect tool for any con-
dition that may affect safe operation.
Immediately repair or replace damaged or
mis-adjusted parts before operating tool.
DISCONNECT TOOLS before servic-
ing, changing accessories, or moving to
another location.
USE RECOMMENDED ACCESSORIES.
Consult this owner’s manual or the manu-
facturer for recommended accessories.
Using improper accessories will increase
the risk of serious injury.
NEVER LEAVE UNATTENDED TOOL
CONNECTED TO AIR. Disconnect the
air hose and do not leave tool until it is
relieved of any built up pressure.
NEVER ALLOW UNTRAINED
USERS TO USE THIS TOOL WHILE
UNSUPERVISED.
IF YOU ARE UNSURE OF THE
INTENDED OPERATION, STOP USING
TOOL. Seek formal training or research
books or magazines that specialize in
pneumatic tools.
BE AWARE OF HOSE LOCATION WHEN
USING PNEUMATIC TOOLS. Hoses can
easily become a tripping hazard when laid
across the floor or spread out in a disorga-
nized fashion.
SECURE WORK. When required, use
clamps or vises to secure workpiece. A
secured workpiece protects hands and
frees both of them to operate the tool.
MAINTAIN TOOLS WITH CARE. Keep
tools lubricated and clean for best and
safest performance. Follow instructions
for lubricating and changing accessories.

Additional Safety for Flooring Nailers
HAND AND FOOT INJURIES. Do not
place your hands or feet near or under
the nail point of entry. A nail/staple can
deflect and tear through the surface of the
workpiece, puncturing your hand or foot.
COMPRESSED AIR RATING. Do not
connect the nailer to compressed air that
exceeds 115 PSI.
ACTUATING MECHANISM. Be careful
not to bump actuating mechanism when
carrying or holding tool while connected
to air. If bumped, the tool may accidentally
shoot in dangerous direction.
SAFE HANDLING. Never point nailer at
others! Carry nailer only by handle, never
by any other part. Do not carry nailer by
air hose.
HOSE USAGE. Make sure your air hose
is designed for tool in use, is in good con-
dition, and is long enough to reach your
work area without stretching. However, an
overly long air hose in the work area may
be a tripping hazard.
OPERATING QUESTIONS. If you are not
sure about intended operation, stop using
nailer. Seek formal training, or research
books or magazines that specialize in
pneumatic tools.
NAILING. Avoid driving one nail/staple on
top of another. The nail/staple may deflect
and cause injury.
AIR SOURCE. Disconnect air source
before installing nails/staples, clearing
jam, moving to another work area, per-
forming maintenance, or when tool is
not in use. A nailer connected to air may
fire accidentally, causing serious personal
injury. DO NOT use check valve or any
other fitting that allows air to remain in
the tool.
COMBUSTIBLE GASES. Never connect
nailer to pressurized oxygen or other com-
bustible gases as a power source. Only
use regulated compressed air.
CLEANING. Never use gasoline or other
flammable liquids to clean nailer; vapors
in nailer will ignite by a spark and cause
it to explode.
TOOL SERVICE. If nailer is leaking air,
damaged, or not working correctly, DO
NOT use before repairing.
HAMMER SAFETY. DO NOT use hammer
with damaged handle or loose head. Make
sure nobody is standing close enough to
be hit when you swing hammer.
No list of safety guidelines can be
complete. Every shop environment
is different. Always consider safe-
ty first, as it applies to your indi-
vidual working conditions. Use this
and other tools with caution and
respect. Failure to do so could result
in serious personal injury, damage to
equipment, or poor work results.

Compressed Air
System
The Model T27338 is designed to be oper-
ated at 70-115 PSI using clean, dry, regu-
lated, compressed air. DO NOT exceed
the 115 PSI maximum operating pres-
sure for your model. Before using, regu-
late the air pressure on your air compres-
sor to 70 psi.
An in-line filter/lubricator/regulator unit,
depicted in Figure 3, can be installed and
should be located as close to the nailer as
possible.
The 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.
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.

SECTION 6: MAINTENANCE
Disconnect the nailer from the air source
before cleaning. Use compressed air to
clean the magazine and discharge area.
Do not allow dust, chips, sand, etc. into
the air connectors or into the body of the
nailer; this may result in leaks and damage
to the nailer and the air couplings.
Never use gasoline or other flamma-
ble liquids to clean this tool. Vapors
in tool may ignite, causing tool to
explode. Ignoring this warning may
lead to serious personal injury or
even death!
Place two to three drops of pneumatic
tool oil in the nailer air inlet (as shown in
Figure 25) before every use and after
every 2 hours of continuous use. Wipe off
any excess oil near the nailer exhaust to

An alternative to manual oiling would be
to simply install a lubricator in your air
compressor line. Refer to Page 7 for addi-
tional information. 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.

ton repair assemblies (part PT27338026)
and O-ring kits (part PT27338061) are
cheap insurance against wasted down
