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 before using the tool. Use the tool only with the Makita genuine fuel cell. Never use the tool in enclosed or poorly ventilated spaces. Always wear safety glasses to protect your eyes from dust or nail injury.

Itis an employer responsibility to enforce the use of safety eye protection equipment by the tool operators and by other persons in the immediate working area. For Australia and New Zealand only Always wear safety glasses and face shield to protect your eyes from dust or naïl injury. The safety glasses and the face shield should conform with the requirements of AS/ NZS 1336.

Itis an employer responsibility to enforce the use of safety eye protection equipment by the tool operators . and by other persons in the immediate working area (Fig. 1) Wear hearing protection to protect your ears against exhaust noise and head protection. Also wear light but not loose clothing. Sleeves should be buttoned or rolled up. No necktie should be worn. Rushing the job or forcing the tool is dangerous. Handle the tool carefully. Do not operate when under the influence of alcohol, drugs or the like. 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. Do not activate the tool unless the tool is placed firmly against the workpiece: Respect the tool as a working implement. No horseplay. Do not hold or carry the tool with a finger on the tigger. Do not load the tool with fasteners when any one . ofthe operating controls is activated. Do not operate the tool with any power source other than that specified in the tool operating safety instructions. An improperly functioning tool must not be used. Sparks sometimes fly when the tool is used. Do not use the tool near volatile, flammable materials such as gasoline, thinner, paint, gas, adhesives, etc. they will ignite and explode, causing serious injury. The area should be sufficiently illuminated to assure safe operations. The area should be clear and litter- free. Be especially careful to maintain good footing and balance 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. 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. Do not operate a tool if any portion of the tool operating controls is inoperable, disconnected, altered, or not working properly. 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 arm is pressed against the wood. It must work only when both actions are performed. Test for possible faulty operation with nails unloaded and the pusher in fully pulled position. 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. Never use fastener driving tools marked with the symbol “Do not use on scaffoldings, ladders” for specific application for example: when changing one driving location to another involves the use of scaffoldings, stairs, ladders, or ladder alike constructions, e.g. roof laths: closing boxes or crates; fitling transportation safety systems e.g. on vehicles and wagons. 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. Make sure there is no one below when working in high locations to prevent danger if there is sudden jerking or catching. 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 nalling 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 too)l itself can react dangerousiy. Place the nails with care: Do not point the ejection port at anyone in the vicinity. Keep hands and feet away from the ejection port area. Never 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 naïling operations immediately if you notice something wrong or out of the ordinary with the tool Always remove the fuel cell, the battery cartridge and all of the nait: (9) When unattended. (10) Before performing any maintenance or repair. (11) Before cleaning a jam. (12) 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. Wipe off all dust from the parts. Do not modify tool without authorization from Makita. Ask Makita's Authorized service centers for periodical inspection of the tool. To maintain product SAFETY and RELIABILITY, maintenance and repairs should be performed by Makita Authorized Service Centers, always using Makita replacement parts.
