IMPORTANT SAFETY INSTRUCTIONS
a) Keep work area clean and well lit. Cluttered and dark areas invite accidents.
b) Avoid dangerous environments. Do not operate power tools in explosive
atmospheres, such as in the presence of flammable liquids, gases or dust.
Power tools create sparks which may ignite the dust or fumes.
c) Keep children and bystanders away while operating a power tool. Distractions
can cause you to lose control.
d) Keep the tool pointed away from yourself and others at all times and keep hands,
any body parts away from work area to guard against possible injury.
e) Use safety equipment. Always wear eye protection and ear protection. Safety
equipment such as dust mask, non-skid safety shoes, hard hat, or hearing
protection should be used for appropriate conditions.
f) Power tool plugs must match the outlet. Never modify the plug in any way.
Do not use any adapter plugs with grounded power tools. Unmodified
plugs and matching outlets will reduce risk of electric shock.
g) Do not keep the trigger or safety depressed during the loading of fasteners as the
unintentional firing of a fastener could cause personal injury.
h) Disconnect the tool from the power source before making any adjustments,
changing accessories, or storing power tools. Such preventive safety measures
reduce the risk of starting the power tool accidentally.
i) Do not fire if the nails/staples are jammed. This will cause damage to the driver
blade and could invite accidents.
j) DO NOT use on hard surface such as rock, concrete, masonry, bricks or steel.
Personal injury or damage to the power tool could result.
k) Do not drive fasteners close to the edge of the work piece.
l) Do not drive fasteners on top of nailed fastener.
m) Only use parts and accessories recommended by manufacturer.
WARNING When using electric tools, machines or equipment, basic safety
precautions should always be followed to reduce the risk of e, electric shock,
and personal injury.
READ
ALL
INSTRUCTIONS BEFORE USING THIS TOOL
3
Always assume that the tool contains nails. Careless handling of the nailer can result in
unexpected firing of nails and personal injury.
Do not point the tool towards yourself or anyone nearby. Unexpected triggering will
discharge the nail causing an injury.
Do not actuate the tool unless the tool is placed firmly against the workpiece. If the
tool is not in contact with the workpiece, the nail may be deflected away from your target.
Disconnect the tool from the power source when the fastener jams in the tool. While
removing a jammed fastener, the nailer may be accidentally activated if it is plugged in or
battery is inserted.
Use caution while removing a jammed nail. The mechanism may be under compression
and the nail may be forcefully discharged while attempting to free a jammed condition.
Do not use this nailer for fastening electrical cables. It is not designed for electric cable
installation and may damage the insulation of electric cables thereby causing electric shock
or fire hazards.
Hold power tool by insulated gripping surfaces, when performing an operation where
the nail may contact hidden wiring. Nails contacting a “live” wire may make exposed metal
parts of the power tool “live” and could give the operator an electric shock.
Know your power tool. Read operator’s manual carefully. Learn its applications and
limitations, as well as the specific potential hazards related to this power tool. Following this
rule will reduce the risk of electric shock, fire, or serious injury.
Always wear eye protection with side shields marked to comply with ANSI Z87.1.
Everyday glasses have only impact resistant lenses. They are not safety glasses. Following
this rule will reduce the risk of serious personal injury.
Eye protection which conforms to ANSI specifications and provides protection against
flying particles both from the FRONT and SIDE should ALWAYS be worn by the
operator and others in the work area when loading, operating or servicing this tool. Eye
protection is required to guard against flying fasteners and debris, which could cause severe
eye injury. The employer and/or user must ensure that proper eye protection is worn. We
recommend. Wide Vision Safety Mask for use over eyeglasses or standard safety glasses
that provide protection against flying particles both from the front and side. Always use eye
protection which is marked to comply with ANSI Z87.1.
Additional safety protection will be required in some environments. For example, the
working area may include exposure to noise levels which can lead to hearing damage. The
employer and user must ensure that any necessary hearing protection is provided and used
by the operator and others in the work area. Some environments will require the use of head
protection equipment. When required, the employer and user must ensure that head
protection conforming to ANSI Z89.1-1997 is used.
Keep fingers away from trigger when not driving fasteners to avoid accidental firing.
Use safety equipment. Always wear eye protection. Dust mask, nonskid safety shoes,
hard hat, or hearing protection must be used for appropriate conditions.
Protect your lungs. Wear a face or dust mask if the operation is dusty. Following this
rule will reduce the risk of serious personal injury.
Protect your hearing. Wear hearing protection during extended periods of operation.
Following this rule will reduce the risk of serious personal injury.
Battery tools do not have to be plugged into an electrical outlet; therefore, they are
always in operating condition. Be aware of possible hazards when not using your battery
tool or when changing accessories. Following this rule will reduce the risk of electric shock,
fire, or serious personal injury.
Do not place battery tools or their batteries near fire or heat. This will reduce the risk of
explosion and possible injury.
Use the tool only for its intended use. Do not discharge fasteners into open air.
Use the tool only for the purpose for which it was designed.
Use only the nails recommended for this tool. Use of the wrong nails could result in poor
nail feeding, jammed nails, and nails leaving the tool at erratic angles. If nails are not feeding
smoothly and properly, discontinue their use immediately. Jammed and improperly feeding
nails could result in serious personal injury.

Depth Adjustment Wheel(FIG. 8)
Depth adjustment helps protect work surface and allows proper setting of
nail heads.
For more depth, turn the depth adjustment wheel towards .
For less depth, turn the wheel to .
Removing a jammed nail or staple(FIG. 9)
Note: You must remove any jammed nail/staple before using the tool .
Otherwise, it could cause damage to the mechanism.
Remove the battery pack from the tool.
Open the magazine, remove the staples or nails in channel.
If the fasteners remain jammed after following the above instructions,
open the nosepiece by pulling upwards, then remove the jammed fastener
pieces(Fig9).
Remove the jammed nail with pliers if necessary. After the jammed nail has
been successfully removed , re-tighten the nose piece securely.
With the magazine open, re-insert the battery and shoot 2-3 times, if all is
clear, reload the nails/staples.
The impact force can be adjusted according to the material by using the
impact force knob.The setting range is between stages 1-6. Stage 1 refers
to the lowest impact force, stage 6 to the highest(Fig.10).
If the impact force is set too high, there is a risk that the material to be
attached will be pierced.
If the impact force is set too low, the staples cannot penetrate the material
deeply enough and will not be attached properly.
The required impact force depends on the material and can be determined
by way of field-testing.
