Three-in-One Air Brad Nailer
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 m anual carefully beforehand to familiarise yourse lf with this product and after
reading, please store this instructional manual for future reference. Failure to follow the proper protocols list ed 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 ar ea clean.
•
Do not allow children to e nter 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 glass es. Safety glasses should conform to ANSI Z87.1 specifications. Safety glasses should be
worn when loading, operating, unloading or servic ing 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 t he tool, carefully check if there are damag ed parts.
•
Replace parts and accessories. Only allow the use of the same replacem ent parts while servicing. Approved
accessories and replacement parts are available.
•
Be alert. Watc h what you are doing. Use common sense. Do not operate any tools while you are tired.
•
Store the nailer when not i n use. The nailer should be cleaned, fully assembled and then stored in a dry
location to reduce r ust. For safety, keep out of reach of children.
•
Pay atte ntion to the air hose and their connections. D on’t trip over hoses. Make sure that all connections are
tight.
•
After loading the fas teners, 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.

Three-in-One Air Brad Nailer
•
When connecting the air, the nail gun may possibly fire the fast eners as soon as you pl ug it into the air hose.
Remove all the fasteners before connection.
•
Do not press the saf ety brack et and the tr igger when loading.
•
If the fasteners are jammed, disc onnect the nail gun and remove the jammed fasteners.
•
Disconnect t he nail g un from the air supply hose before doing mainte nance, 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 c ontains fasteners. Do not aim the tool at yourself or others.
•
Do not load fast eners with the trigger or safety is pressed to prevent unintentional firing of a fastener.
•
Remove your finger f rom 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 trigg e r is pressed.
•
Grip the nail gun firm ly to maintain control, while allowi ng it to recoil away from the work surface as the
fastener is driv en. If the safety bracket is allowed to connect with the work surface again before the tr igger is
released, an unwanted f astener may be fired.
•
Do not drive fasteners on top of other fasteners, or with the tool at a st eep 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 , allo w ing 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. Commo n sense and ca ution 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 maxim um and m inimum pressure. Pressure that is too high or low will c ause 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 t o the tool as possible (see Fig. 1) .
•
Keep the air filter clean. A dirty filter will reduce air pr essure, 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 connect ions in the air supply system are sealed to pr event 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 t he tool from the air supply. Grasp the nailer firmly with one hand.
Press the latch with your t hum b 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 s ure that the air pressure is in the correct range denoted in the
technical data.
4. Test the driving dept h 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 t he nail g un unless the safety nose is in contact with the work piece. Do not operate t he 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 awa y f rom your holding hand.
3. Squeeze the trigger.
4. For continuous naili ng, squeeze the trigger repeatedl y.
Clearing a Jammed Fastener
1. Disconnect the tool from the air suppl y.
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 throug h the airline
connection will l ubricate the inside parts. An automatic airline oiler is recommended but oil may be added
manually before every operation or after about 1 hour of c ontinuous use. Only a few drops of oil at a time are
necessary.
•
Use only pneumatic t ool 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-o ut. Use a filter/oiler for better
performance and longer lif e. The filter must have enough flow capacity for the specific applicat ion.
•
Keep tools clean for bet ter and safer performance. Use non-flammable cleaning solutions (Caution: such
solutions m ay dam age the O-r ing and other tool parts do not soak unless neces sary).
•
Check if there are worn and dam aged parts.
•
Inspect trigger and safety mechanism to assure the system is complete and functional; no loose or missing
parts, no binding or sticking parts.
