Important SAFETY Instructions for Pneumatic Tools
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.
DEFINITIONS - SAFETY GUIDELINES
The definitions below describe the level of severity for each
signal word. Please read the manual and pay attention to
these symbols.
Indicates an imminently hazardous
situation which, if 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.
Used without the safety alert symbol
indicates a situation which, if not avoided, may result in
property damage.
• Actuating tool may result in flying debris,
collation material, or dust which could harm
operator’s eyes. Operator and others in work
area MUST wear safety glasses with side
shields. These safety glasses must conform to
ANSI Z87.1 requirements (approved glases have
“Z87” printed or stamped on them). 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)
• 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. Conden­sation
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 an 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, whichever 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 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 an unintentional fastener
discharge during connection. The tool driving
mechanism may cycle when the tool is connected
to the air supply. Do not load fasteners with the
trigger or the contact trip depressed to prevent
unintentional driving.
• 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 parts should be repaired or replaced
before use. Refer to Repairs. (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.
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 bump action mode
(contact actuation mode) If contact trip is allowed
to recontact work surface before trigger is
released an unwanted fastener will be driven.
Choice of triggering method is important.
Check the manual for triggering options.
Bump or contact actuation trigger
• When using the bump action trigger,
be careful of unin­
tentional double fires
resulting from tool recoil. Unwanted
fasteners may be driven if the contact trip
is allowed to accidentally re-contact the
work surface. (Fig. T)
To Avoid Double Fires:
• Do not engage the tool against the work
surface with a strong force.
• Allow the tool to recoil fully after each
actuation.
• Use sequential action trigger.
• When bump actuating the nailer, always
keep tool in control. Inaccurate placement
of tool can result in misdirected discharge
of a fastener.
Sequential action trigger
• When using the sequential action trigger,
do not actuate the tool unless the tool is
placed firmly against the workpiece.
depth adjustment: To reduce risk of
serious injury from accidental actuation when
attempting to adjust depth, ALWAYS:
• Disconnect air supply.
• Avoid contact with trigger during
adjustments.
Do not drive nails blindly into walls, floors
or other work areas. Fasteners driven into
live electrical wires, plumbing, or other types of
obstructions can result in injury. (Fig. U)
Stay alert, watch what you are doing and
use common sense when operating a power
tool. Do not use tool while tired or under the
influence of drugs or alcohol. A moment of
inattention while operating power tools may
result in serious personal injury.

Actuating Tool
To reduce the risk of injury, Always wear proper eye [ANSI Z87.1 (CAN/
CSA Z94.3)] and hearing protection [ANSI S12.6 (S3.19)] when operating this tool.
The tool can be actuated using one of two modes: single sequential action trigger mode and
bump action trigger mode.
Sequential action trigger Red trigger (Fig. 1)
The sequential action triger’s intended use is for intermittent fastening where very careful and
accurate placement is desired.
To operate the nailer in sequential action mode:
1. Depress the contact trip firmly against the work surface.
2. Pull the trigger.
A fastener will be driven each time the trigger is pulled as long as the contact
trip remains depressed which could result in accidental driving.
Black trigger (Fig. 1)
Bump action trigger The bump action trigger’s intended use is for rapid fastening on flat, stationary surfaces.
Using the bump action trigger, two methods are available: place actuation and bump
actuation.
To operate the tool using the place actuation method:
1. Pull the contact trip against the work surface.
2. Pull the trigger.
To operate the tool using the bump actuation method:
1. Pull the trigger.
2. Push the contact trip against the work surface. As long as the trigger is pulled, the tool
will drive a fastener every time the contact trip is depressed. This allows the user to
drive multiple fasteners in sequence.
Do not keep trigger pulled when tool is not in use.
Adjusting Depth (Fig. 4)
To reduce risk of serious injury from accidental actuation when
attempting to adjust depth, ALWAYS:
• Disconnect the tool from the air supply.
• Avoid contact with trigger during adjustments.
The depth that the fastener is driven can be adjusted using the depth adjustment next to the
trigger of the tool.
1. To drive the fastener shallower, rotate the depth setting wheel (J) to the right.
2. To drive a fastener deeper, rotate the depth setting wheel (J) to the left.
Clearing a Jammed Fastener
