Preface
Thanks for buying the Nailer, another high-quality machine from our company.
To get the most out of your purchase, please read the manual before using the Nailer.
We ask you to please read this manual carefully beforehand to familiarise yourself with this product and after
reading, please store this instructional manual for future reference. Failure to follow the proper protocols listed in
the manual may cause personal injury to the operator or damage to equipment.
Safety Information
WARNING! ENSURE THAT NO PART OF ANY HUMAN, ANIMAL OR CLOTHING IS PLACED IN/NEAR THE
AREA WHERE NAILS ARE FIRED OUT OF THE GUN, REGARDLESS OF WHETHER YOU THINK THE GUN IS
EMPTY OR LOADED WITH NAILS.
•Keep your working area clean.
•Do not allow children to enter areas where the nailer is stored or in use, or handle the nailer even if the nailer
is unpowered.
•Do not operate the nailer under the influence of alcohol or drugs.
•Use safety glasses. Safety glasses should conform to ANSI Z87.1 specifications. Safety glasses should be
worn when loading, operating, unloading or servicing the nailer.
•Use ear protection. Exposure to high noise levels can lead to hearing damage.
•Never use oxygen combustible gases, bottled gases or high pressure compressed gas as a power source
for this tool as it may explode and cause serious injury.
•Dress safely. Protective gloves and non-skid footwear or safety shoes are recommended when working with
and operating the nailer. Do not wear loose clothing or jewellery as they can get caught in moving parts.
Also, wear a protective hair covering to prevent your hair from getting caught in the nailer.
•When operating the tool, keep proper footing and balance to avoid damage resulting from losing balance.
•Before using the tool, carefully check if there are damaged parts.
•Replace parts and accessories. Only allow the use of the same replacement parts while servicing. Approved
accessories and replacement parts are available.
•Be alert. Watch what you are doing. Use common sense. Do not operate any tools while you are tired.
•Store the nailer when not in use. The nailer should be cleaned, fully assembled and then stored in a dry
location to reduce rust. For safety, keep out of reach of children.
•Pay attention to the air hose and their connections. Don’t trip over hoses. Make sure that all connections are
tight.
•After loading the fasteners, never point the nail gun at yourself or others.
•Use the correct air connector. The connector on the nail gun must not hold pressure when the air supply is
disconnected. If the wrong fitting is used, the nail gun can be charged with air after being disconnected and
still be able to drive a fastener.

•When connecting the air, the nail gun may possibly fire the fasteners as soon as you plug it into the air hose.
Remove all the fasteners before connection.
•Do not press the safety bracket and the trigger when loading.
•If the fasteners are jammed, disconnect the nail gun and remove the jammed fasteners.
•Disconnect the nail gun from the air supply hose before doing maintenance, clearing a jammed fastener,
leaving the work area, moving the nail gun to another location, or handing it to another person.
•Always assume the tool contains fasteners. Do not aim the tool at yourself or others.
•Do not load fasteners with the trigger or safety is pressed to prevent unintentional firing of a fastener.
•Remove your finger from the trigger when not driving fasteners. Never carry a tool with your finger on the
trigger; the gun will fire a fastener if the safety is bumped while the trigger is pressed.
•Grip the nail gun firmly to maintain control, while allowing it to recoil away from the work surface as the
fastener is driven. If the safety bracket is allowed to connect with the work surface again before the trigger is
released, an unwanted fastener may be fired.
•Do not drive fasteners on top of other fasteners, or with the tool at a steep angle; the fastener can ricochet,
causing personal injury.
•Do not drive fasteners close to the edge of the work piece. The work piece is likely to split, allowing the
fastener to fly free or ricochet, causing personal injury.
The warnings and instructions explained in this instruction manual cannot cover all possible conditions and
situation that may occur. Common sense and caution are factors which cannot be built into this product and
must be supplied by the operator.

Assembly
Air System
•Use clean, dry and regulated compressed air at 4-7 bar (60-100psi).
•Never exceed maximum and minimum pressure. Pressure that is too high or low will cause noise, excess
wear and tear or misfiring.
•When connecting the air supply, always keep hands and body away from the discharge area of the tool.
•A filter-regulator lubrication is required and should be located as close to the tool as possible (see Fig. 1).
•Keep the air filter clean. A dirty filter will reduce air pressure, causing a reduction in power and efficiency.
•For better performance, install a quick connector in your tool and quick coupler on the hose.
•Be sure that all connections in the air supply system are sealed to prevent air loss.
Figure 1
Loading Fasteners
Always disconnect the tool from the compressed air before loading.
When loading the tool, always point the tool away from yourself or others.
Make sure that you are not holding the tool with trigger depressed while loading the
tool.
1. Disconnect the tool from the air supply. Grasp the nailer firmly with one hand.
Press the latch with your thumb and pull the magazine back. Insert the fasteners into the magazine keeping
the point down.
2. Release the latch and pusher. Slide the pusher against the nails until it contacts the nails and locks into
place.
3. Connect the tool to the air supply. Make sure that the air pressure is in the correct range denoted in the
technical data.
4. Test the driving depth in a sample piece of wood before use. If the fastener is being driven too far or not far
enough, adjust the regulator to provide more or less air pressure.
Never operate the nail gun unless the safety nose is in contact with the work piece. Do not operate the nail gun
without fasteners, this will cause damage to the nailer.
Never fire fasteners into the air because this may cause injury to the operator or others.

Operating Instructions
Using the Nailer
1. Press the safety bracket against the intended project.
2. Hold your intended project down but make sure that the nailer is still far away from your holding hand.
3. Squeeze the trigger.
4. For continuous nailing, squeeze the trigger repeatedly.
Clearing a Jammed Fastener
1. Disconnect the tool from the air supply.
2. Open the latch, check for bent or misfired nails and remove those nails from the lower housing.
3. Use a slender, soft steel rod to push the drive blade to the uppermost position.
4. Use needle nose pliers to remove the jammed fastener.
Regular Maintenance
•Frequent, but not excessive lubrication is required for best performance. Oil added through the airline
connection will lubricate the inside parts. An automatic airline oiler is recommended but oil may be added
manually before every operation or after about 1 hour of continuous use. Only a few drops of oil at a time are
necessary.
•Use only pneumatic tool oil. Do not use detergent oil or additives as these lubricants will cause accelerated
wear-out of the seal.
•Use a small amount of oil on all moving surfaces and pivots.
•Dirt and water in the air supply are major causes of pneumatic tool wear-out. Use a filter/oiler for better
performance and longer life. The filter must have enough flow capacity for the specific application.
•Keep tools clean for better and safer performance. Use non-flammable cleaning solutions (Caution: such
solutions may damage the O-ring and other tool parts do not soak unless necessary).
•Check if there are worn and damaged parts.
•Inspect trigger and safety mechanism to assure the system is complete and functional; no loose or missing
parts, no binding or sticking parts.
