Risk of head injury.
WHAT COULD HAPPEN
Metal fragments, fasteners, or other
material could be projected against
head or into eyes resulting in serious
injury or property damage. Contin-
ued exposure to an operating tool
can result in permanent hearing dam-
age.
HOW TO PREVENT IT
Always wear ANSI approved Z87
safety glasses, Z89.1 head protec-
tion and S3.19 hearing protection.
HAZARD TO LOOK FOR
Injury to eyes, head and hearing
Risk of puncture injury.
WHAT COULD HAPPEN
A fastener could accidentally be
driven if the contact trip safety
mechanism is not working resulting
in serious injury or property damage.
If the contact trip bumps something
or someone while holding the tool
with the trigger depressed, serious
injury or property damage could oc-
cur.
Improper handling can result in dam-
age to the contact trip safety mecha-
nism resulting in unsafe operation.
Accidental discharge of a fastener
can occur, resulting in serious injury
or property damage.
HOW TO PREVENT IT
Do not remove, modify or bypass
contact safety device.
Do not use the tool if any shields or
guards are removed or altered.
Always check contact trip safety
mechanism of the tool before each
use.
Never carry the tool by the hose or
pull the hose to move the tool or a
compressor. Keep hoses away from
heat, oil and sharp edges. Replace
any damaged, weak or worn hoses.
Hold tool by the handle and keep
trigger and contact trip safety mecha-
nism from contacting objects or parts
of the body when connecting or dis-
connecting air supply.
Disconnect air hose before loading
fasteners, removing a jammed fas-
teners.
HAZARD TO LOOK FOR
Injury to eyes, head and hearing

PAGE 6
Risk from flying objects.
WHAT COULD HAPPEN
Fasteners could ricochet or be
propelled causing serious injury or
property damage.
When working along edges or next
to voids in work surface, the con-
tact trip safety mechanism could
be depressed and allow the tool
to discharge a fastener into the air
or through thin work materials re-
sulting in serious injury or property
damage.
HAZARD TO LOOK FOR
Injury to self or others in the work area.
HOW TO PREVENT IT
Pay attention to others in the work
area to assure that they are pro-
tected from possible accidental
discharge of fastener, or projected
fragments of work material, fas-
teners, etc.
Provide ANSI approved Z87 safety
glasses, Z89.1 head protection,
and S3.19 hearing protection to
self and others in the work area.
Never point discharge of tool at
self or others.
Do not pull trigger unless tool con-
tact safety device is against work
surface.
Never attempt to drive fasteners
into hard surfaces such as steel,
concrete, or tile.
Take care to avoid driving a fas-
tener on top of another fastener.
Before operating tool, be certain
that work surfaces are strong
enough and thick enough to con-
tain entire fastener.
Position tool carefully so that fas-
teners will be delivered to the
proper location.

PAGE 7
Do not store the tool in cold weather. Frost
or ice can form on the operating valves or
mechanisms and the tool may not operate
correctly.
In cold weather operation (near or below
freezing), DO NOT USE a permanent
antifreeze such as ethylene glycol for a
cold weather lubricant. This type of
anitfreeze will damage o-rings and seals
of the tool.
NOTE
Proper lubrication is the owner's re-
sponsibility. Failure to lubricate the tool
properly will dramatically shorten the life
of the tool and void your warranty.
1. Disconnect the air supply from the tool
before manually lubricating.
Your tool requires lubrication before
you use it for the first time and before
and after each additional use. If an Oiler
is used, manual lubrication through the air
inlet is not required on a daily basis.
Lubrication prevents wear and prevents
rust from forming.
LUBRICATION AND MAINTENANCE
2. Turn the tool so the air inlet is facing up
and put one drop of DeVilbiss AC230 Air
Tool Oil, high speed spindle oil, such as
Unocal RX22, or 3-in-1 oil into the air
inlet. DO NOT USE detergent oil or addi-
tives. Operate the tool briefly after add-
ing oil. (See Figure 1)
DO NOT OVER LUBRICATE AIR TOOL.
3. Wipe off excessive oil at the exhaust.
NOTE
Many air tool users find it convenient to use
an Oiler to help provide oil circulation
through tool. An Oiler also increases the
efficiency and useful life of the tool. An oiler
is recommended for tools that receive heavy
or constant use. Check oil level in the oiler
daily. (See Figure 2)
Many air tool users find it convenient to use
a Filter to remove liquid and solid impuri-
ties which can rust or "gum up" internal
parts of the tool. A Filter also increases the
efficiency and useful life of the tool. Drain
water from the filter periodically. (See
Figure 3)

PAGE 8
Always connect the Female Quick Cou-
pler to the air hose. Never connect the
Female Quick Coupler to the tool.
Never carry the tool by the hose or pull
the hose to move the tool or a com-
pressor. Keep hoses away from heat,
oil, and sharp edges. Replace any
damaged, weak or worn hoses.
Do not use any type of flammable gases
or oxygen as a power source for the tool.
Use filtered, lubricated, regulated com-
pressed air only. Use of compressed gas
instead of compressed air may cause
the tool to explode and cause death or
serious personal injury.
NOTE
For better performance, install a 3/8"
Quick Connector (1/4" NPT threads)
with an inside diameter of .315 (8 mm) on
your Tool and a 3/8" Quick Coupler on
the air hose. A minimum of 3/8" I.D. air
hose with a rated working pressure of
150 PSI or above should be used.
NOTE
Excessive oil will damage o-rings and
seal of tool. If in-line oiler is used,
manual lubrication through the air
inlet is not required on a daily basis.
Regulator
Oiler
Air Flow
Figure 3
The air compressor must be able to maintain
a minimum of 65 PSI when the tool is being
used. An inadequate air supply can cause a
loss of power or inconsistent operation.
Do not use a check valve or any other
fittings which will allow air to remain in
the tool. Serious personal injury or prop-
erty damage could occur.
Use a Pressure Regulator on your
compressor with an operating pressure
of 0-125 PSI. A Pressure Regulator is
required to control the operating pres-
sure of your tool. Refer to the label on
your nailer/stapler for the maximum
P.S.I.

Never keep the trigger pulled on contact
trip tools when carrying or holding the
tool. Death or a serious puncture wound
could occur if the contact trip bumps
something or someone.
Do not hold the tool against the work
surface with extra force. Allow the tool
to drive the fastener.
Do not use the contact trip mechanism
as a means of discharging a fastener
because:
1. It could result in personal injury
2. It could result in an accidential
release of a fastener.
3. It may cause damage to the
mechanism.
4. It could result in improper place-
ment of fastener in work piece.
Keep your hands and body away from
the fastener discharge area of the tool.
Serious personal injury or property dam-
age could occur.
CONTACT TRIP SAFETY
MECHANISM
Your Nailer/Stapler is a contact trip oper-
ated tool. When the operator depresses
the contact trip safety mechanism against
the work surface and then pulls the trigger,
a fastener will be driven.
