• Due to our continuing programme of research and development, the specifications herein are subject to change without notice.
• Note: Specifications may differ from country to country. IMPORTANT SAFETY INSTRUCTIONS (3) Do not actuate the tool unless the tool is placed firmly against the workpiece. (4) Respect the tool as a working implement. USB086-1 (5) No horseplay.

WARNING: WHEN USING THIS TOOL,

BASIC SAFETY PRECAUTIONS SHOULD

ALWAYS BE FOLLOWED TO REDUCE

THE RISK OF PERSONAL INJURY, INCLUDING THE FOLLOWING: (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. 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 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. 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.

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.

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. 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.

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. 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.

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

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

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/cm2G (200 PSIG).

26. 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.

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.

27. 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.

14. Always check the tool for its overall condition

and loose screws before operation. Tighten as required.

28. Stop nailing operations immediately if you

notice something wrong or out of the ordinary with the tool.

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.

29. 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.

16. Make sure that the trigger is locked when the

change lever is set to the LOCK position. (4) Before moving the tool to a new location.

17. 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.

30. 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.

18. Use only nails specified in this manual. The use

of any other nails may cause malfunction of the tool.

31. When not operating the tool, always lock the trigger by turning the change lever to the LOCK

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

32. Do not modify tool without authorization from

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

21. 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.

34. Always check contact element as instructed in

this manual. Nails may be driven accidentally if the safety mechanism is not working correctly.

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

22. 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.

36. 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

23. 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.

WARNING:

MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury.

24. 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.

SYMBOLS Selecting air hose

USD501-1 The followings show the symbols used for tool. ....................Read and understand tool labels and manual. ....................Operators and others in work area must wear safety glasses with side shields. ....................Keep fingers away from trigger when not driving fasteners to avoid accidental firing. 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/cm2G (70 PSIG), an air hose with an internal diameter of over 8.5 mm (5/16”) 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/cm2G (150 PSIG) or 150 percent of the maximum pressure produced in the system whichever is

higher. INSTALLATION Selecting compressor 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.

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.

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.

Nailing frequency (times/min) Thus, for example, if nailing takes place at a rate of approximately 40 times per minute at a compression of

6.0 kgf/cm2G (85 PSIG), a compressor with an air output

over 3 ft3/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.

FUNCTIONAL DESCRIPTION ASSEMBLY CAUTION: Always lock the trigger and disconnect the hose before adjusting or checking function on the tool.

CAUTION: Always lock the trigger and disconnect the hose before carrying out any work on the tool.

Nose adapter Loading nailer When nailing workpieces with easily-marred surfaces, use the nose adapter. It is factory installed at the rear of the tool.

1. Nose piece storing portion

Select nails suitable for your work. Depress the latch lever and open the door and magazine cap. Lift and turn the coil support plate to set it to the correct step. When loading 90 (3-1/2”) mm long nails, use the bottom step. When loading 65 (2-1/2”) or 75 (3”) mm long nails, use the middle step. When loading 45 (1-3/4”) or 50 (2”) or 57 (2-1/4”) mm long nails, use the top step. If the tool is operated with the coil support plate set to the wrong step, poor nail feed or malfunction of the tool may result. Attach the nose adapter to the contact arm. When not in use, store the nose adapter at the rear of the tool to keep it from being lost.

Adjusting depth of nailing

1. Adjuster

Place the nail coil over the coil support plate. Uncoil enough nails to reach the feed claw. Place the first nail in the driver channel and the second nail in the feed claw. The nail heads must be in the slot in the feeder body. Place other uncoiled nails on feeder body. Close the magazine cap and door after checking to see that the nail coil is set properly in the magazine.

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 (1/32”) increments per graduation. If nails cannot be driven deep enough even when the arrow points to the number 1, increase the air pressure. If nails are driven too deep even when the arrow points to the number 9, 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 number.

Connecting air hose could occur, if contact element is allowed to re-contact against the workpiece or the other surface under the influence of recoil. In order to avoid this unexpected nailing, perform as follows; A. Do not place the contact element against the workpiece with excessive force. B. Pull the trigger fully and hold it on for 1-2 seconds after nailing.

• For No. 1 method, set the change lever to the “Intermittent Nailing” position. For No. 2 method, set the change lever to the “Continuous Nailing” position. After using the change lever to change the nailing method, always make sure that the change lever is properly set to the position for the desired nailing method.

1. Air fitting

2. Air socket

Lock the trigger. Slip the air socket of the air hose onto the air fitting on the nailer. Be sure that the air socket locks firmly into position when installed onto the air fitting. A hose coupling must be installed on or near the tool in such a way that the pressure reservoir will discharge at the time the air supply coupling is disconnected.

CAUTION: Make sure all safety systems are in working order before operation. To drive a nail, you may place the contact element against the workpiece and pull the trigger, or

CAUTION: Operating the tool without nails shortens the life of the tool and should be avoided. Air exhaust

1. Exhaust cover

Pull the trigger first and then place the contact element against the workpiece.

Air exhaust direction can be changed easily by rotating the exhaust cover. Change it when necessary. 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, do as follows: Open the door and magazine cap and remove the nail coil. Insert a small rod or the like into the ejection port and tap it with a hammer to drive out the nail jamming from the ejection port. Reset the nail coil and close the magazine cap and door.

No. 1 method is for intermittent nailing, when you wish to drive a nail carefully and very accurately. No. 2 method is for continuous nailing. CAUTION: However when the tool is set to the “Intermittent Nailing” mode, WITH THE TRIGGER HELD IN A HALF-PULLED POSITION, an unexpected nailing

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. Avoid storing nails in a very humid or hot place or place exposed to direct sunlight.

CAUTION: Always disconnect the air hose from the tool before attempting to perform inspection or maintenance. Maintenance of nailer The hook is convenient for hanging the tool temporarily. This hook can be installed on either side of the tool.

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

CAUTION: Always lock the trigger and disconnect the hose when hanging the tool using the hook. Always tighten the hook securing bolt firmly. Loose bolt may cause air leakage from the tool. Never hang the tool on a waist belt or like. Dangerous accidental firing may result.

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.

Make sure that the trigger is locked when the change lever is set to the LOCK position.

Keep the air hose away from heat (over 60°C, over 140°F), 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.

Maintenance of compressor, air set and air hose To maintain product SAFETY and RELIABILITY, repairs, any other maintenance or adjustment should be performed by Makita Authorized or Factory Service Centers, always using Makita replacement parts. 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.
