filings or wood chips.
Personal safety
g.
h.
Always wear eye protec-
tion. Wear ANSI-ap-
proved safety goggles with
side shields during use.
a. Stay alert. Watch what you are do-
ing and use common sense when
operating the tool. Do not use the
tool while tired or under the influ-
ence of drugs, alcohol, or medica-
tion. A moment of inattention while
operating the tool increases the risk
of injury to persons.
Always wear hearing
protection when using
the tool. Prolonged expo-
sure to high intensity noise
is able to cause hearing loss.
b. Dress properly. Do not wear loose
clothing or jewelry. Contain long
hair. Keep hair, clothing, and
gloves away from moving parts.
Loose clothes, jewelry, or long hair
increases the risk of injury to persons
as a result of being caught in moving
parts.
Tool use and care
a.
Avoid unintentional
misfires. Be sure Trigger
(59) is in the OFF posi-
tion when not in use and
before plugging in. Do
not carry any tool with your finger on
the Trigger, whether it is attached to
an air source or not. Do not point tool
towards yourself or anyone whether it
contains nails or not.
c. Avoid unintentional starting. Be
sure the switch is off before con-
necting to the air supply. Do not
carry the tool with your finger on the
switch or connect the tool to the air
supply with the switch on.
b. Do not load nails with Trigger or
safety depressed. Unintentional fir-
ing may occur. Always assume Nailer
contains fasteners.
d. Remove adjusting keys and
wrenches before turning the tool
on. A wrench or a key that is left at-
tached to a rotating part of the tool
increases the risk of personal injury.
c. Do not load fasteners when Nailer
is connected to air hose. Always
assume tool contains fasteners. Unin-
tentional firing may occur.
e. Do not overreach. Keep proper
footing and balance at all times.
Proper footing and balance enables
better control of the tool in unexpect-
ed situations.
d. Properly adjust Nailer angle to
match corresponding fasteners
before inserting nail strip. Failure
to do so can cause Nailer to jam and
lead to personal and/or property dam-
age.
f.
Use safety equipment. A
dust mask, non-skid safety
shoes and a hard hat must
be used for the applicable
conditions. Wear heavy-duty work
e. Fire nails into an appropriate work
surface only. Do not attempt to fire

cleat nails or staples into surfaces
too hard to penetrate. Do not drive
cleat nails or staples on top of other
cleat nails or staples, or at too steep
an angle. Cleat nails and staples can
ricochet, causing personal injury.
Never fire this tool into the air or point
it toward yourself or another person.
m. Maintain the tool with care. Keep
tool clean. A properly maintained tool,
reduces the risk of binding and is
easier to control.
n. Check for misalignment or bind-
ing of moving parts, breakage of
parts, and any other condition that
affects the tool’s operation. If dam-
aged, have the tool serviced before
using. Many accidents are caused
by poorly maintained tools. There is a
risk of bursting if the tool is damaged.
f.
Hold tool away from head and
body during use. Tool may kick
back, causing injury.
g. Do not fire fasteners too close to
edge of workpiece. They may split
the workpiece and fly free, causing
personal injury.
o. Use only accessories that are
identified by the manufacturer for
the specific tool model. Use of an
accessory not intended for use with
the specific tool model, increases the
risk of injury to persons.
h. Carry tool safely. Carry tool by
handle.
i.
Use clamps or another practical
way to secure and support the
workpiece to a stable platform.
Holding the work by hand or against
the body is unstable and is able to
lead to loss of control.
Service
a. Tool service must be performed
only by qualified repair personnel.
b. When servicing a tool, use only
identical replacement parts. Use
only authorized parts.
j.
Do not force the tool. Use correct
tool for application. The correct tool
will do the job better and safer at the
rate for which the tool is designed.
c. Use only the lubricants supplied
with the tool or specified by the
manufacturer.
k. Disconnect the tool from the air
source before making any adjust-
ments, changing accessories, or
storing the tool. Such preventive
safety measures reduce the risk
of starting the tool unintentionally.
Turn off and detach the air supply
and safely discharge any residual
air pressure before leaving the work
area.
Air source
a.
Never connect to an air
source that is capable of
exceeding 120 PSI. Over
pressurizing the tool may
cause bursting, abnormal operation,
breakage of the tool or serious injury
to persons. Use only clean, dry,
regulated compressed air at the rated
pressure or within the rated pressure
range as marked on the tool (70 to
120 PSI). Always verify prior to using
l.
Store the tool when it is idle out of
reach of children and other un-
trained persons. A tool is dangerous
in the hands of untrained users.

standards, and warrants to the original purchaser that this product is free from defects in materials
and workmanship for the period of 90 days from the date of purchase. This warranty does not apply to
damage due directly or indirectly, to misuse, abuse, negligence or accidents, repairs or alterations outside
our facilities, criminal activity, improper installation, normal wear and tear, or to lack of maintenance. We
shall in no event be liable for death, injuries to persons or property, or for incidental, contingent, special
or consequential damages arising from the use of our product. Some states do not allow the exclusion
or limitation of incidental or consequential damages, so the above limitation of exclusion may not apply

To take advantage of this warranty, the product or part must be returned to us with transportation charges

If our inspection verifies the defect, we will either repair or replace the product at our election or we may
elect to refund the purchase price if we cannot readily and quickly provide you with a replacement. We will
return repaired products at our expense, but if we determine there is no defect, or that the defect resulted
from causes not within the scope of our warranty, then you must bear the cost of returning the product.
This warranty gives you specific legal rights and you may also have other rights which vary from state to
state.
