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 Instructions for Nailers/
Staplers
HAND INJURIES: Do not place your
hands near the nail/staple point of entry.
A nail/staple can deflect and tear through
the surface of the workpiece, puncturing
your hand or fingers.
COMBUSTIBLE GASES: Never connect
the nailer/stapler to pressurized oxygen
or other combustible gases as an air
source. Only use filtered, lubricated, and
regulated compressed air.
SAFE HANDLING: Never point the nailer/
stapler at others! Do not keep the trigger
pulled when loading fasteners, carrying,
or holding tool. Carry the tool only by the
handle, never by any other part. Do not
carry the tool by the air hose. Disconnect
the nailer/stapler from the air hose when
going up and down ladders.
MODIFICATIONS: DO NOT modify this
tool or bypass the safety nose mecha-
nism.
COMPRESSED AIR RATING: Do not
connect the nailer/stapler to compressed
air that exceeds 120 PSI.
HOSE USAGE: Make sure your air hose
is designed for the tool in use, is in good
condition, and is long enough to reach
your work 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 the intended operation,
stop using the nailer/stapler. Seek formal
training.
CLEANING: Never use gasoline or
other flammable liquids to clean the
nailer; vapors in the nailer/stapler will
ignite by a spark and cause it to explode.
MAINTENANCE: Always disconnect air
from the nailer/stapler when servicing or
installing nails. During maintenance, a
nailer/stapler connected to air may fire
accidentally, causing serious personal
injury.
CHECK VALVE: Do not use a check
valve or any other fitting that allows air to
remain in the tool after it is disconnected
from the air source.

Operating this nailer can propel
objects into the air, causing imme-
diate eye damage. To protect your-
self, always wear American National
Standards Institute (ANSI) approved
safety glasses or goggles when oper-
ating this equipment. In addition, this
nailer discharges at up to 85-90 deci-
bels. To protect your hearing, always
wear ANSI approved ear protection
when operating this nailer.
Never point this nailer at yourself or
another person! Always pay attention
to the direction this nailer is pointed.
Use this tool with respect and caution
to lessen the possibility of operator or
bystander injury. Ignoring this warning
may result in serious personal injury.
Nailer/stapler accidents routinely hap-
pen while moving the gun to another
location, such as up ladders, to anoth-
er room, or even another job site.
Always disconnect the gun immedi-
ately after use and never transport the
gun while connected to the air—even
if the air compressor is disconnected
from its power source!
No list of safety guidelines can be
complete. Every shop environment is
different. Always consider safety first,
as it applies to your individual 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.
Read the manual before operation.
Become familiar with this nailer, its
safety instructions, and its operation
before beginning any work. Serious
personal injury may result if safety or
operational information is not under-
stood or followed.

The Model H5527 is designed to be oper-
ated at 70-110 PSI using clean, dry, regu-
lated, compressed air. DO NOT exceed
the 120 PSI maximum operating pres-
sure for your model.
Before using your new nailer, 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 2, can be installed and
should be located as close to the nailer as
possible.
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.

ing a filter/lubricator/regulator unit in your
compressed air system, always follow the
connection instructions that come with
the unit.
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!

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:
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.
Safety Nose
Mechanism
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
Grizzly Technical Support at (570)
546-9663 for help.
— If the nailer fires when the trigger
is pulled, without the safety nose
mechanism being depressed, then
the nailer is not working properly.
— If you find that the safety nose
mechanism is not working properly,
check the lubrication of its sliding
components.
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.
