SAFETY INSTRUCTIONS FOR POWER TOOLS

When using power tools, always observe the safety regulations applicable
in your country to reduce the risk of fire, electric shock and personal injury.
Read the following safety instructions before attempting to operate this
product. Keep these instructions in a safe place.

GENERAL POWER TOOL SAFETY WARNINGS

WARNING! Read all safety warnings and all instructions Failure to
follow the warnings and instructions may result in electric shock,
fire and/or serious injury.

power source for this tool. Danger of explosion and/or
serious personal injury may result. (Fig. E)

• Use couplings that relieve all pressure from the
tool when it is disconnected from the power supply.

Use hose connectors that shut off air supply from
compressor when the tool is disconnected. (Fig. F)

• Disconnect tool from air supply when not in use.
Always disconnect tool from air supply and remove
fasteners from magazine before leaving the area
or passing the tool to another operator. Do not
carry tool to another work area in which changing
location involves the use of scaffoldings, stairs,
ladders, and the like, with air supply connected. Do
not make adjustments, remove magazine, perform
maintenance or clear jammed fasteners while
connected to the air supply. If the contact trip is

adjusted when the tool is connected to the air supply
and nails are loaded, accidental discharge may occur.
(Fig. G)

• Connect tool to air supply before loading fasteners,
to prevent a fastener from being fired during
connection. The tool driving mechanism may cycle

when tool is connected to the air supply. Do not load
fasteners with trigger or contact trip depressed, to
prevent unintentional firing of a fastener.

• Do not remove, tamper with, or otherwise cause the
tool, trigger, or contact trip to become inoperable.

Do not tape or tie trigger or contact trip in the on
position. Do not remove spring from contact trip. Make
daily inspections for free movement of trigger and
contact trip. Uncontrolled discharge could result.

• Inspect tool before use. Do not operate a tool if
any portion of the tool, trigger, or contact trip is
inoperable, disconnected, altered, or not working
properly. Leaking air, damaged parts or missing par ts

should be repaired or replaced before use. (Fig. H)

• Do not alter or modify the tool in any way. (Fig. I)

• Always assume that the tool contains
fasteners.

• Do not point the tool at co-workers or yourself at any
time. No horseplay! Work safe! Respect the tool as a

working implement. (Fig. J)

• Keep bystanders, children, and visitors away while
operating a power tool. Distractions can cause you

to lose control. When tool is not in use, it should be
locked in a safe place, out of the reach of children.

• Remove finger from trigger when not driving
fasteners. Never carry tool with finger on trigger.

Accidental discharge could result. Using the trigger
lock-off will prevent accidental discharge.

• Do not overreach. Maintain proper footing and
balance at all times. Loss of balance may cause
personal injury. (Fig. K)

• Make sure hose is free of obstructions or snags.

Entangled or snarled hoses can cause loss of balance
or footing.

• Use the tool only for its intended use. Do not

discharge fasteners into open air, concrete, stone,
extremely hard woods, knots or any material too
hard for the fastener to penetrate. Do not use the
body of the tool or top cap as a hammer. Discharged

fasteners may follow unexpected path and cause
injury. (Fig. L)

• Always keep fingers clear of contact trip to prevent
injury from inadvertent release of nails. (Fig. M)

• Refer to the Maintenance and Repairs sections for
detailed information on the proper maintenance of
the tool.

• Always operate the tool in a clean, lighted area. Be

sure the work surface is clear of any debris and be
careful not to lose footing when working in elevated
environments such as rooftops.

• Do not drive fasteners near edge of material. The
workpiece may split causing the fastener to ricochet,
injuring you or a co-worker. Be aware that the nail
may follow the grain of the wood (shiner), causing it
to protrude unexpectedly from the side of the work
material. Drive the nail perpendicular to the grain to
reduce risk of injury. (Fig. N)

• Do not drive nails onto the heads of other
fasteners or with the tool at too steep an angle.

Personal injury from strong recoil, jammed fasteners,
or ricocheted nails may result. (Fig. O)

• Be aware of material thickness when using the
nailer. A protruding nail may cause injury.

• Be aware that when the tool is being utilized at
pressures on the high end of its operating range,
nails can be driven completely through thin or very
soft work material. Make sure the pressure in the

compressor is set so that nails are set into the material
and not pushed completely through. (Fig. P)

• Keep hands and body parts clear of immediate work
area. Hold workpiece with clamps when necessary to

keep hands and body out of potential harm. Be sure
the workpiece is properly secured before pressing the
nailer against the material. The contact trip may cause
the work material to shift unexpectedly. (Fig. Q)

• Do not use tool in the presence of flammable dust,
gases or fumes. The tool may produce a spark that

could ignite gases causing a fire. Driving a nail into
another nail may also cause a spark. (Fig. R)

• Keep face and body parts away from back of the
tool cap when working in restricted areas. Sudden

recoil can result in impact to the body, especially when
nailing into hard or dense material. (Fig. S)

• Grip tool firmly to maintain control while allowing
tool to recoil away from work surface as fastener is
driven. In “Contact Actuation Mode” if contact trip is

Important Safety Instructions for Pneumatic
Tools

WARNING: When using any pneumatic tool, all safety
precautions, as outlined below, should be followed to avoid
the risk of death or serious injury. Read and understand all
instructions before operating the tool.

• Actuating tool may result in flying debris, collation

material, or dust which could harm operator’s eyes.

The operator and all those persons in the general area
should wear safety glasses with permanently attached
side shields. Approved safety glasses are imprinted
with the characters “Z87.1”. It is the employer’s
responsibility to enforce the use of eye protection
equipment by the tool operator and other people in the
work area. (Fig. A)

• Minimize flying dust and debris by rotating 360˚

exhaust to appropriate setting.

• Always wear appropriate personal hearing and other

protection during use. Under some conditions and

duration of use, noise from this product may contribute
to hearing loss. (Fig. A)

• Use only clean, dry, regulated air. Conden sation from

an air compressor can rust and damage the internal
workings of the tool. (Fig. B)

• Regulate air pressure. Use air pressure compatible

with ratings on the nameplate of the tool. (Not to

exceed 120 psi, 8.3 bar) Do not connect the tool to a
compressor rated at over 175 psi. The tool operating
pressure must never exceed 175 PSI even in the event
of regulator failure. (Fig. C)

• Only use air hose that is rated for a maximum

working pressure of at least 150 PSI (10.3 BAR) or
150% of the maximum system pressure, which ever
is greater. (Fig. D)

• Do not use bottled gases to power this tool. Bottled

compressed gases such as oxygen,
carbon dioxide, nitrogen, hydrogen, propane, acetylene
or air are not for use with pneumatic tools. Never use
combustible gases or any other reactive gas as a
