IMPORTANT SAFETY INSTRUCTIONS WARNING: WHEN USING THIS TOOL, BASIC SAFETY PRECAUTIONS SHOULD ALWAYS BE FOLLOWED TO REDUCE THE RISK OF PERSONAL INJURY, INCLUDING THE FOLLOWING: READ ALL INSTRUCTIONS. For personal safety and proper operation and maintenance of the tool, read this instruction manual carefully before using the tool. Always wear safety glasses to protect your eyes from dust or nail injury. The safety glasses should conform with the requirements of ANSI 287. 1 - 1979.
General Tool Handling Guidelines: 1. Always assume that the tool contains fasteners. 2. Do not point the tool toward yourself or anyone whether it contains fasteners or not. 3. Do not actuate the tool unless the tool is placed firmly against the workpiece. 4. Respect the tool as a working implement. 5. No horseplay. 6. Do not hold or carry the tool with a finger on the trigger. 7. Do not load the tool with fasteners when any one of the operating controls is activated. 8.
Only those involved in the work should be in the vicinity. Children especially must be kept away at all times. There may be local regulations concerning noise which must be complied with by keeping noise levels within prescribed limits. In certain cases, shutters should be used to contain noise. I Shutter *Do not play with the contact element: it prevents accidental discharge, so it must be kept on and not removed. Securing the trigger in the ON position is also very dangerous.
*Never use the tool with other than compressed air. If bottled gas (carbon dioxide, oxgen, nitrogen, hydrogen, air, etc.) or combustible gas (hydrogen, propane, acetylene, etc.) is used as a power source for this tool, the tool will explode and cause serious injury. COMPRESSED AIR Always check the tool for its overall condition and loose screws before operation. Tighten as required. Make sure all safety systems are in working order before operation.
Make sure that the trigger is locked when the change lever is set to the LOCK position. Change lever Trigger lock Check walls, ceilings, floors, roofing and the like carefully to avoid possible electrical shock, gas leakage, explosions, etc. caused by striking live wires, conduits or gas pipes. Use only nails specified in this manual. The use of any other nails may cause malfunction of the tool.
Make sure no one is nearby before nailing. Never attempt to nail from both the inside and outside at the same time. Nails may rip through andlor fly off, presenting a grave danger. *Watch your footing and maintain your balance with the tool. Make sure there is no one below when working in high locations, and secure the air hose to prevent danger if there is sudden jerking or catching. L On rooftops and other high locations, nail as you move forward.
Do not leave the loaded tool or the air compressor under pressure for a long time out in the sun. Be sure that dust, sand, chips and foreign matter will not enter the tool in the place where you leave It setting. Do not point the ejection port at anyone in the vicinity. Keep hands and feet away from the ejection port area. *When the air hose is connected, do not carry the tool with your finger on the trigger or hand it to someone In this condition. Accidental firing can be extremely dangerous.
Stop nailing operations immediately if you notice something wrong or out of the ordinary with the tool. * I I Always disconnect the air hose and remove all of the nails: 1. When unattended. 2. Before performing any maintenance or repair. 3. Before cleaning a jam. 4. Before moving the tool to a new location. Perform cleaning and maintenance right after finishing the job. Keep the tool in tip-top condition. Lubricate moving parts to prevent rusting and minimize friction related wear.
Do not operate this tool if it does not contain a legible WARNING LABEL. I I Do not modify tool without authorization from Makita. Ask Makita’s Factory or Authorized service center for periodical inspection of the tool. To maintain product SAFETY and RELIABILITY, maintenance and repairs should be performed by Makita Authorized or Factory Service Centers, always using Makita replacement parts. SAVE THESE INSTRUCTIONS.
TOOL INSTALLATION INSTRUCTIONS AND US€ Selecting compressor The air compressor must comply with the requirements of ANSI 819.3 - 1981. Select a compressor that has ample pressure and air output to assure cost-efficient operation. The graph shows the relation between nailing frequency, applicable pressure and compressor air output. Thus, for example, if nailing takes place at a rate of approximately 40 times per minute at a compression of 0.49 MPa (70 PSIG).
Selecting wirelplastic collated coil According to the type of collated coil, set the change lever. lever Wire collated I - . Plastic 111 collated coil Loading nailer CAUTION: *Always lock the trigger and disconnect the hose before loading the nailer. Make sure that nails are collated firmly and are not bent. Select nails suitable for your work. Pull the lever of the magazine cap and open the magazine cap.
Adjusting depth of nailing CAUTION: Always lock the trigger and disconnect the hose before adjusting the depth of nailing. To adjust the depth of nailing, turn the adjuster so that the arrow above the adjuster will point to the number indicated on the adjuster. The depth of nailing is the deepest when the arrow points to the number 1. It will become shallower as the arrow points to higher number. The depth can be changed in approx. 1.0 mm (1132”) increments per graduation.
Continuous nailing and trigger locking method For continuous nailing, set the change lever to the ”Continuous Nailing” position. For locking the trigger, set the change lever to the ”Lock” position. Always make sure that the change lever is properly set to the position. CAUTION: I Operating the tool without nails shortens the life of the tool and should be avoided. Air exhaust Air exhaust direction can be changed easily by rotating the exhaust cover. Change it when necessary. . I . . . .
*Never hang the tool on a waist belt or the like. Dangerous accidental firing may result. Nails Handle nail coils and their box carefully. If the nail coils have been handled roughly, they may be out of shape or their connector breaks, causing poor nail feed.
MAINTENANCE CAUTION: Always be sure that the trigger is locked and the air hose is disconnected from the tool before attempting to perform inspection or maintenance. Maintenance of nailer Alwavs check the tool for its overall condition and loess screws before operation. Tighten as required. Make sure all safety systems are in working order before operation. The tool must not operate ifonly the trigger is pulled or if only the contact element is pressed against the wood.
When not in use, lock the trigger and disconnet the hose. Then cap the air fitting with the cap. When the tool is not to be used for an extended period of time, lubricate the tool using pneumatic tool oil and store the tool in a safe place. Avoid exposure to direct sunlight and/or a humid or hot environment. Iron dust that adhere to the magnet can be blown off by using an air duster. - Maintenance of compressor, air set and air hose After operation, always drain the compressor tank and the air filter.
Check regularly to see if there is sufficient pneumatic oil in the oiler of the air set. Failure to maintain sufficient lubrication will cause O-rings to wear quickly. Keep the air hose away from heat (over 6OoC, over 14OOF), away from chemicals (thinner, strong acids or alkalis). Also, route the hose away from obstacles which it may become dangerously caught on during operation. Hoses must also be directed away from sharp edges and areas which may lead to damage or abrasion to the hose.
