SAFETY INSTRUCTIONS

1) Read and understand tool labels and the manual. Failure to follow warnings, dangers, and precautions could result in death or serious injury.

2) Keep work area clean.

Cluttered areas invite injuries.

3) Don’t allow children at the work area. Do not let them handle the tool.

4) Do not operate the tool if under the influence of alcohol or drugs. Read warning labels on prescriptions to determine if your judgment or reflexes are impaired while taking drugs. If there is any doubt, do not attempt to operate.

5) Use safety glasses. Safety glasses should conform to ANSI

Z87.1 specifications. Before operating, wear safety glasses against flying debris from the front and side. Safety glasses should be worn when loading, operating, unloading, or servicing this tool.

6) Use ear protection. The working area may be exposed to high noise levels that can lead to hearing damaged.

7) Never use oxygen combustible gases, bottled gases or high pressure compressed gas as a power source for this tool. The tool may explode and cause serious injury.

8) Dress safely. Protective gloves and nonskid footwear or safety shoes are recommended when working with and operating this tool. Don’t wear loose clothing or jewelry. They can get caught in moving parts. Also, wear a protective hair covering to prevent long hair from getting caught in the tool.

9) Do not fire to hard materials.

Do not attempt to shoot toward hard or brittle material such as concrete, steel, or tile.

10) When operating tool, keep the proper footing and balance to avoid damage resulting from losing balance.

11) Check damaged parts before using the tool.

12) Replace parts and accessories. Only allow approved replacement parts.

13) Keep alert. Watch what you are doing. Use common sense.

Do not operate any tool when you are tired.

14) Store the tool. When not in use, tool should be cleaned, fully assembled and then, stored in a dry location to reduce rust. For safety, keep out of reach of children.

16) Pay attention to the air hose and their connections. Don’t trip over hoses. Make sure all connections are tight.

17) After loading the fasteners, never point the tool at yourself or any bystanders.

18) Use the correct air connector.

The connector on the tool must not hold pressure when the air supply is disconnected. If the wrong fitting is used, the tool can be charged with air after being disconnected and still be able to drive a fastener.

19) When connecting the air, the tool can possibly fire the fasteners. Therefore, remove all the fasteners before connecting to the air.

20) Do not depress the safe bracket and the trigger when loading.

21) If the fasteners are jammed, disconnect the tool from the air and remove the jammed fasteners.

22) This tool is equipped with the safe bracket that can adjust the depth of the driver. When adjusting the depth of the driver, first disconnect the tool from the air and rotate nut by thumb to satisfactory position.

WARNING The warnings, cautions, and instructions explained in this instruction manual cannot cover all possible conditions and situations that may occur. It must be understood by the operator that common sense and caution are factors which cannot be built into this product, but must be supplied by the operator.

SETTING

Your air tool is fully assembled when you receive it. Before using it, attach the air line and desired air system accessories.

See figure below for the recommended accessories and connection order. Be sure the air hose is depressurized when installing or removing adapters to the air line.

CONNECTING THE TOOL TO

AN AIR SUPPLY

1) Determine if the tool needs oil and, if necessary, place two drops of oil in the air plug. If you are using an automatic in-line oiler, check and add oil if necessary.

2) Turn the compressor on and set the regulator to the proper pressure for the size and type of fasteners being used.

3) Connect the tool to the air supply.

LOADING THE FASTENERS

1) Depress the lock to release the movable magazine and pull the magazine out fully as shown below.

2) Place a full clip of the specified type and size fasteners on the fixed magazine, up to 100 fasteners may be loaded in the magazine.

3) Push the movable magazine assembly forward until it was locked.

OPERATING THE TOOL

Test the driving depth in a sample piece of wood before using. If the fasteners are being driven too far or not far enough, adjust the regulator to provide less air pressure or more air pressure.

1) Connect the tool to the air supply. Make sure the air pressure is in correct range.

2) Load the fastener as above the direction given in the LOAD

THE FASTENERS section.

3) Hold the body and press the drive guide to the work surface.

Be sure the tool is straight and then gently depress the trigger to drive the fastener.

4) Lift the tool off the work surface.

5) The tool has two driving modes.

§ Put the nose on the work surface, lightly push the tool towards the working surface until the safe bracket is depressed.

Depress the trigger to drive the fastener.

§ Depress the trigger, then repeatedly impact the safe bracket. The tool can repeatedly drive the fasteners. The tool will drive one fastener when the safe bracket is impacted one time.

REGULAR MAINTENANCE

1) Frequent, but not excessive, lubrication is required for best performance. Oil added through the airline connection will lubricate internal 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. Too much oil will collect inside the tool and be blown out during the exhaust cycle. ONLY USE PNEUMATIC

TOOL OIL. Do not use detergent oil or additives as these lubricants will cause accelerated wear to the seal in the tool.

2) Use a small amount of oil on all moving parts and pivots.

3) Dirt and water in the air supply are major causes of pneumatic tool wear. Use a filter/oiler for better performance and longer life. The filter must have adequate flow capacity for the specific application. Consult the manufacturer’s instructions for proper maintenance of your filter.

4) Keep tools clean for better and safer performance. Use nonflammable cleaning solutions (CAUTION: Such solutions may damage O-Ring and other tool parts) only if necessary. DO NOT SOAK.
