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.

1. For personal safety and proper operation and maintenance of the tool, read this instruction manual carefully before using the tool.

2. Always wear safety glasses to protect your eyes from dust or nail injury. The safety glasses should conform with the requirements of ANSI Z87.1. WARNING: It is an employer's responsibility to enforce the use of safety eye protection equipment by the tool operators and by other persons in the immediate working area.

3. 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.

4. 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.

5. 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.

Net weight 2.4 kg (5.2 lbs)

USB087-1

(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) Do not operate the tool with any power

source other than that specified in the tool operating/safety instructions.

6. An improperly functioning tool must not be used.

7. 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.

8. 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.

9. Only those involved in the work should be in the vicinity. Children especially must be kept away at all times.

10.

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.

11.

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.

12.

Operate the tool within the specified air pressure on the tool label for safety and longer tool life. Do not exceed the recommended max. operating pressure. The tool should not be connected to a source whose pressure potentially exceeds 14.0 kgf/cm

G (200 PSIG).

13.

Never use the tool with other than compressed air. If bottled gas (carbon dioxide, oxygen, 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.

14. Always check the tool for its overall condition and loose screws before operation. Tighten as required.

15. 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 the contact element in fully pulled position.

16.

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.

17. Use only nails specified in this manual. The use of any other nails may cause malfunction of the tool.

18. Do not permit those uninstructed to use the tool.

19. 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.

20. 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.

21. 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.

22. 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.

23. 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.

24. Do not point the ejection port at anyone in the

vicinity. Keep hands and feet away from the ejection port area.

25. 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.

26. 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.

27. Stop nailing operations immediately if you notice something wrong or out of the ordinary with the tool.

28. Always disconnect the air hose and remove all of the nails:

(9) When unattended. (10) Before performing any maintenance or

repair.

(11) Before cleaning a jam. (12) Before moving the tool to a new location.

29. 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.

30. Do not modify tool without authorization from Makita.

31. Do not attempt to keep the trigger or contact element depressed with tape or wire. Death or serious injury may occur.

32. Always check contact element as instructed in this manual. Nails may be driven accidentally if the safety mechanism is not working correctly.

33. Ask Makita's Authorized service centers for periodical inspection of the tool.

34. To maintain product SAFETY and RELIABILITY, maintenance and repairs should be performed by Makita Authorized or Factory Service Centers, always using Makita replacement parts.

The air compressor must comply with the requirements of ANSI B19.3. 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 37 times per minute at a compression of

7.0 kgf/cm output over 2 ft

G (100 PSIG), a compressor with an air

/minute is required. Pressure regulators must be used to limit air pressure to the rated pressure of the tool where air supply pressure exceeds the tool's rated pressure. Failure to do so may result in serious injury to tool operator or persons in the vicinity.

Selecting air hose

004294

Use an air hose as large and as short as possible to assure continuous, efficient nailing operation. With an air pressure of 5.0 kgf/cm

G (70 PSIG), an air hose with an internal diameter of over 6.5 mm (1/4") and a length of less than 20 m (6.6 ft.) is recommended when the interval between each nailing is 0.5 seconds. Air supply hoses shall have a minimum working pressure rating of

10.7 kgf/cm

G (150 PSIG) or 150 percent of the maximum pressure produced in the system whichever is higher.

CAUTION:

• Low air output of the compressor, or a long or

smaller diameter air hose in relation to the nailing frequency may cause a decrease in the driving capability of the tool.

Lubrication

004295

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. For proper lubrication, the tool must be fired a couple of times after pneumatic tool oil is introduced.

To adjust the depth of nailing, turn the adjuster. The depth of nailing is the deepest when the adjuster is turned fully in the A direction shown in the figure. It will become shallower as the adjuster is turned in the B direction. If nails cannot be driven deep enough even when the adjuster is turned fully in the A direction, increase the air pressure. If nails are driven too deep even when the adjuster is turned fully in the B direction, decrease the air pressure. Generally speaking, the tool service life will be longer when the tool is used with lower air pressure and the adjuster set to a lower depth of nail driving.

CAUTION:

• Always disconnect the hose before adjusting the

depth of nailing.

MAINTENANCE

CAUTION:

• Always disconnect the air hose from the tool before

attempting to perform inspection or maintenance.

Cleaning and removal of tat and dirt

Adhesion of tar and dirt to areas around the contact element will prevent smooth movement of the contact element (safety mechanism), causing accidental discharge. Periodically clean the areas around the contact element. Use a solvent such as kerosene, #2 fuel oil or diesel fuel. Immerse only the contact element and the areas around the ejection port in solvent and remove tar and dirt with brush. Always wear waterproof gloves to protect your hands. Never immerse the housing, magazine, etc. in solvent. Malfunction of the tool may result. Always dispose of the solvent used in a safe and prudent manner and in compliance with all local and national code requirement.

1. Brush

2. Ejection port

008401

Dry off the tool before use. Any oil film left after cleanup will accelerate the tar buildup, and the tool will require more frequent recleaning. After drying off the tool, oil the moving parts to prevent rusting and to assure good lubrication and operation or moving parts.

WARNING:

• Never use gasoline or other similar highly volatile

liquids for cleaning. Vapors of such liquids may

enter the tool and could be ignited by sparks

produced during nailing and cause an explosion.

Maintenance of nailer

Always check the tool for its overall condition and loose screws before operation. Tighten as required.

008403

008404

Maintenance of compressor, air set and air hose

1. Drain cock

008402

With tool disconnected, make daily inspection to assure free movement of the contact element and trigger. Do not use tool if the contact element or trigger sticks or binds.

008409

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 humid or hot environment.

004317

004318

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 to wear quickly.
