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 activate 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 L Shutter Do not remove, tamper with, or otherwise cause the tool operating controls to become inoperable.
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 the safety mechanism is in working order before operation.
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. .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. When not operating the tool, always lock the trigger by turning the lock knob (lock pin). Ask Makita's Factory or Authorized service center for periodical inspection of the tool.
TOOL INSTALLATION INSTRUCTIONS AND USE 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.
Nose adapter CAUTION: Always lock the trigger and disconnect the hose before installing or removing the nose adapter. To prevent the workpiece from being damaged or scratched, attach the nose adapter to the contact arm so that the protrusion of the nose adapter will fit into the hole in the contact arm. I \ \ Nose adapter When not using the nose adapter, store it in the storage cavity. itorage cavity Loading nailer CAUTION: Always lock the trigger and disconnect the hose before loading the nailer.
Adjusting depth of nailing CAUTION: Always lock the trigger and disconnect the hose before adjusting the depth of nailing. Adjust the depth of nailing by turning the adjuster. The depth of nailing is the deepest when the adjuster is set at the 2.5 graduation. It will become shallower as the adjuster is set to a lower graduation. The depth can be changed in approx. 0.5 mm (1/64") increments per graduation. If nails are driven too deep even when the adjuster is set to 0 graduation, decrease the air pressure.
3. Depress the contact arm against the workpiece. 4. Pull the trigger to drive a nail. To drive another nail, release the trigger and lift the tool from the workpiece. Then repeat this procedure. Nails cannot be driven if you depress the contact arm against the workpiece after pulling the trigger. \ Pull the trigger after depressing the contact arm against the workpiece. Trigger activation 1. Place the contact arm against the workpiece. Turn the activation lever to the "Trigger Activation" position. 2.
Jammed nailer CAUTION: Always lock the trigger, disconnect the hose and remove the nails from the magazine before cleaning a jam. When the nailer becomes jammed, proceed as follows: Remove the hex wrench 3 from the hook. Hook I Hex wrench 3 Remove the two bolts which secure the driver guide. Remove the driver guide. Remove the jammed nail from the ejection slot. \ Bolt Driver guide To reassemble the tool, perform the above operations in reverse sequence.
Nails Handle nail strips and their box carefully. If the nail strips Avoid storing nails in a very humid or hot place or place exposed to direct sunlight.
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 Always check the tool for its overall condition and loose screws before operation. Tighten as required. Make sure the safety mechanism is in working order before operation. First, disconnect the hose from the tool and open the magazine.
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. - 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 t o wear quickly.
