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. Wear light but not loose clothing. Sleeves should be buttoned or rolled up. No necktie should be worn. .Always wear safety glasses to protect your eyes from dust or nail injury.
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.Never depress the operating control unless the nosepiece of the tool is directed toward the workpiece. 4. Respect the tool as a working implement. 5. No horseplay. U 6. Do not transport the tool with the operating control depressed. 7. Do not load the tool with fasteners with the work-contacting element or operating control depressed.
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. Do not tamper with the tool or attempt to use it for other than nailing. 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 attempt to fasten the trigger.
*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. The tool must not operate if only the trigger is pulled or if only the contact element is pressed against the wood. It must work only when both actions are performed. Test for possible faulty operation with nails unloaded and with the pusher locked at fully pulled position. (See page 11 for the method of locking the pusher.
Use only nails specified in this manual. The use of any other nails may cause malfunction of the tool. Do not permit those uninstructed to use the tool. I ... . .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 and/or fly off, presenting a grave danger. Watch your footing and maintain your balance with the tool.
On rooftops and other high locations, nail as you move forward. It is easy to lose your footing if you nail while inching backward. When nailing against perpendicular surface, nail from the top to the bottom. You can perform nailing operations with less fatigue by doing so. A nail will be bent or the tool can become jammed if you mistakenly nail on top of another nail or strike a knot in the wood. The nail may be thrown and hit someone, or the tool itself can react dangerously. Place the nails with care.
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. Handle the tool carefully as there is high pressure inside the tool that can be dangerous if a crack is caused by rough handling (dropping or striking). Do not attempt to carve or engrave on the tool. Stop nailing operations immediately if you notice something wrong or out of the ordinary with the tool.
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. Wipe off all dust from the parts. Ask Makita’s Factory or Authorized service center for periodical inspection of the tool. SAVE THESE INSTRUCTIONS.
TOOL INSTALLATION INSTRUCTIONS AND USE Lubrication To insure maximum performance, install an air set (oiler, regulator, air filter) as close as possible to the tool. Adjust the oiler so that one drop of oil will be provided for every 30 nails. When an air set is not used, oil the tool with pneumatic tool oil by placing 2 (two) or 3 (three) drops into the air fitting. This should be done before and after use.
Unloading nailer CAUTION: Always disconnect the air hose before unloading the nailer. Pull the pusher fully to the rear and depress the lock button. While keeping the lock button depressed, release your finger from the pusher to lock the pusher with the lock button. Point the rear of the magazine downward to remove the strip of nails from the magazine.
Selecting compressor The air compressor must comply with the requirements of ANSI B19.3 - 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 a t a rate of approximately 3 0 times per minute at a compression of 5 kgf/cm2G (70 PSIG), a compressor with an air output over 3 0 liters/minute is required.
Operation 1 ) To drive a nail, you may place the contact element against the workpiece and pull the trigger, or 2 ) Pull the trigger first and then place the contact element against the workpiece. N o . 1 method is for intermittent nailing, when you wish to drive a nail carefully and very accurately. No. 2 method is for continuous nailing. For the No. 1 method (intermittent nailing), set the change lever to the position where its pin fits into the RIGHT hole in the trigger. For the No.
Jammed nailer CAUTION: Always disconnect the air hose before clearing a jam. The door of this tool is designed to open automatically when a jam occurs. If it does not open automatically, open it by hand. To do so, first disconnect the air hose. Then pull the door toward the tool body and open it. If the door cannot be opened by hand, use a slotted screwdriver. Insert the screwdriver between the door and the driver guide. Twist the screwdriver to pry open the door.
Nails Handle nail strips and their box carefully. If the nail strips have been handled roughly, they may be out of shape or their connector breaks, causing poor nail feed. Avoid storing nails in a very humid or hot place or place exposed to direct sunlight.
MAINTENANCE CAUTION: Always be sure that the air hose is disconnected from the tool before attempting to perform inspection or maintenance. Maintenance of nailer 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. The tool must not operate if only the trigger is pulled or if only the contact element is pressed against the wood. It must work only when both actions are performed.
Maintenance of compressor, air set and air hose After operation, always drain the compressor tank and the air filter. If moisture is allowed to enter the tool, it may result in poor performance and possible tool failure. l----7 Drain cock I Check regularly t o 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.
