9. 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.

On rooftops and other high locations, drive faste ners as you move forward. It is easy to lose your footing if you drive fasteners while inching backward. When driving fasteners against perpendicular surface, work from the top to the bottom. You can perform driving operations with less fatigue by doing so.

11. A fastener will be bent or the tool can become

jammed if you mistakenly drive fastener on top of another fastener or strike a knot in the wood. The fastener may be thrown and hit someone, or the tool itself can react dangerously. Place the fasteners with care.

12. 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.

13. Never attempt to drive fasteners from both the

inside and outside at the same time. Fasteners may rip through and/or fly off, presenting a grave danger. Repetitive motions hazards

1. When using a tool for long periods, the operator

may experience discomfort in the hands, arms, shoulders, neck, or other parts of the body.

2. While using a tool, the operator should adopt a

suitable but ergonomic posture. Maintain secure footing and avoid awkward or off-balanced postures.

3. If the operator experiences symptoms such as

persistent or recurring discomfort, pain, throbbing, aching, tingling, numbness, burning sensation, or stiffness, do not ignore these warning signs. The operator should consult a qualified health professional regarding overall activities.12

4. The continuous use of the tool may cause

repetitive stain injury due to recoil produced by the tool.

5. To avoid repetitive strain injury, the operator

should not overreach or use excessive force. Additionally, the operator should take a rest when feeling fatigue.

6. Conduct a risk assessment regarding repetitive

motion hazards. It should focus on muscular- skeletal disorders and be preferentially based on the assumption that decreasing fatigue during work is effective in reducing disorders. Accessory and consumable hazards

1. Disconnect the energy supply to the tool, such

as air or gas or battery as applicable, before changing/replacing accessories such as workpiece contact, or making any adjustments.

2. Use only the sizes and types of accessories that

are provided by the manufacturer.

3. Use only lubricants recommended in this

manual. Workplace hazards

1. Slips, trips and falls are major causes of

workplace injury. Be aware of slippery surfaces caused by use of the tool and also of trip hazards caused by the air line hose.

2. Proceed with additional care in unfamiliar

surroundings. Hidden hazards may exist, such as electricity or other utility lines.

3. This tool is not intended for use in potentially

explosive atmospheres and is not insulated from coming into contact with electric power.

4. Make sure there are no electrical cables, gas

pipes etc. that could cause a hazard if damaged by use of the tool.

5. Keep work area clean and well lit. Cluttered or

dark areas invite accidents.

6. 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. Dust and exhaust hazards

1. Always check your surroundings. The air

exhausted from the tool may blow dust or objects and hit operator and/or bystanders.

2. Direct the exhaust so as to minimize disturbance

of dust in a dust filled environment.

3. If dust or objects are emitted in the work area,

reduce the emission as much as possible to reduce the health hazards and risk of injury. Noise hazards

1. Unprotected exposure to high noise levels can

cause permanent, disabling, hearing loss and other problems such as tinnitus (ringing, buzzing, whistling or humming in the ears).

2. Conduct a risk assessment regarding noise

hazards in the work area and implement appropriate controls for these hazards.

3. Appropriate controls to reduce the risk may

include actions such as damping materials to prevent workpieces from “ringing”.

4. Use appropriate hearing protection.

5. Operate and maintain the tool as recommended

in these instructions, to prevent an unnecessary increase in noise levels.

6. Take noise reduction measures, for example

placing workpieces on sound damping supports. Vibration hazards

1. The vibration emission during operation

depends on the gripping force, the contact pressure force, the working direction, the adjustment of energy supply, the workpiece, the workpiece support. Conduct a risk assessment regarding vibration hazards and implement appropriate controls for these hazards.

2. Exposure to vibration can cause disabling

damage to the nerves and blood supply of the hands and arms.

3. Wear warm clothing when working in cold

conditions, keep your hands warm and dry.

4. If you experience numbness, tingling, pain or

whitening of the skin in your fingers or hands,

ek medical advice from a qualified occupational health professional regarding overall activities.

5. Operate and maintain the tool as recommended

in these instructions, to prevent an unnecessary increase in vibration levels.

6. Hold the tool with a light, but safe, grip because

the risk from vibration is generally greater when the grip force is higher. Additional warnings for pneumatic tools

2. Always shut off air supply, and disconnect tool

from air supply when not in use.

3. Always disconnect the tool from the

compressed air supply before changing accessories, making adjustments and/or repairs, when moving away from an operating area to a different area.

4. Keep fingers away from trigger when not

operating the tool and when moving from one operating position to another.

5. Never direct compressed air at yourself or

6. Whipping hoses can cause severe injury. Always

check for damaged or loose hoses or fittings.

7. Never carry a pneumatic tool by its hose.

8. Never drag a pneumatic tool by its hose.

9. When using pneumatic tools, do not exceed the

maximum operating pressure ps max.

10. Pneumatic tools should only be powered by

compressed air at the lowest pressure required for the work process to reduce noise and vibration, and minimize wear.

11. Using oxygen or combustible gases for

operating pneumatic tools creates a fire and explosion hazard.

12. Be careful when using pneumatic tools as the

tool could become cold, affecting grip and control.13 Additional warnings for tools with contact actuation capability

1. Do not rest your finger on the trigger when

picking up the tool, moving between operating areas and positions or walking, as resting finger on trigger can lead to inadvertent operation. For tools with selective actuation, always check the tool before use to ascertain the correct mode is selected.

2. This tool has either selective actuation for

contact actuation or continuous contact actuation by actuation mode selectors or is a contact actuation or continuous actuation contact tool and has been marked with the symbol above. Its intended uses are for production applications such as pallets, furniture, manufactured housing, upholstery and sheathing.

3. If using this tool in selective actuation mode,

always ensure it is in the correct actuation setting.

4. Do not use this tool in contact actuation for

applications such as closing boxes or crates and fitting transportation safety systems on trailers and lorries.

5. Be careful when changing from one driving

location to another. Safety devices

1. 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 fasteners unloaded and the pusher in fully pulled position.

2. Securing the trigger in the ON position is very

dangerous. Never attempt to fasten the trigger.

3. Do not attempt to keep the contact element

depressed with tape or wire. Death or serious injury may occur.

4. Always check contact element as instructed in

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

finishing the job. Keep the tool in tip-top condition. Lubricate moving parts to prevent rusting and minimize frictionrelated wear. Wipe off all dust from the parts.

2. Ask Makita authorized service center for

periodical inspection of the tool.

3. To maintain product SAFETY and RELIABILITY,

maintenance and repairs should be performed by Makita Authorized Service Centers, always using Makita replacement parts.

4. Follow local regulations when disposing of the

tool. SAVE THESE INSTRUCTIONS.

WARNING: DO NOT let comfort or familiarity with

product (gained from repeated use) replace strict adherence to safety rules for the subject product. MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury. PARTS DESCRIPTION (Fig. 1) INSTALLATION Selecting compressor The air compressor must comply with the requirements of EN60335-2-34. 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 30 times per minute at a compression of

0.69 MPa (6.9 bar), a compressor with an air output over

80 L/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 (Fig. 2) Use an air hose as large and as short as possible to assure continuous, efficient nailing operation. With an air pressure of 0.49 MPa (4.9 bar), an air hose with an inter- nal diameter of over 6.5 mm and a length of less than 20 m is recommended when the interval between each nailing is 0.5 seconds. Air supply hoses shall have a min- imum working pressure rating of 1.03 MPa (10.3 bar) 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 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. (Fig. 3) 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 fit- ting. 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. (Fig. 4) FUNCTIONAL DESCRIPTION CAUTION:

• Always disconnect the air hose before adjusting or checking function on the tool. Adjusting depth of nailing (Fig. 5) 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. Use the nose adapter (Fig. 6) CAUTION:

• Always disconnect the hose before installing or remov- ing the nose adapter. If you like to protect the surface of workpiece, attach the nose adapter of contact element. When nailing workpieces with easily-marred surfaces, use the nose adapter. To attach the nose adapter to the contact element, press it onto the contact element until the protrusion in three places inside the nose adapter fit in three holes in the contact element. ASSEMBLY CAUTION:

• Always disconnect the air hose before carrying out any work on the tool. Loading nailer Select nails suitable for your work. Depress the latch lever and open the door. And then open the magazine cap. (Fig. 7) Lift and turn the coil support plate so that the arrow with nail size indicated on the coil support plate will point to the corresponding graduation increment marked on the magazine. 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. (Fig. 8) 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. Place other uncoiled nails on feeder body. Close the magazine cap after checking to see that the nail coil is set properly in the magazine. (Fig. 9) Connecting air hose (Fig. 10) 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 cou- pling 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. OPERATION CAUTION:

• Make sure all safety systems are in working order before operation. Selecting the operation mode CAUTION:

• Always make sure that the change lever is properly set to the position for the desired nailing mode before nail- ing. This tool is equipped with the change lever. You can select either the single sequential actuation mode or the contact actuation mode with it. (Fig. 11) Single sequential actuation mode: You can drive one nail by one sequential operation. Select this mode when driving a nail carefully and accu- rately. To choose this mode, set the change lever to the position. Contact actuation mode: You can drive nails repetitively by placing the contact ele- ment with the trigger held. To choose this mode, set the change lever to the position. Checking proper action before operation Before operation, always check following points. – Make sure that the tool does not operate only by con- necting the air hose. – Make sure that the tool does not operate only by pulling the trigger. – Make sure that the tool does not operate only by plac- ing the contact element against the workpiece without pulling the trigger. – In single sequential actuation mode, make sure that the tool does not operate when pulling the trigger first and then placing the contact element against the work- piece. Single sequential actuation Place the contact element against the workpiece and pull the trigger fully. After nailing, release the contact element, and then release the trigger. (Fig. 12) CAUTION:

• Do not place the contact element against the workpiece with excessive force. Also, pull the trigger fully and hold it on for 1-2 seconds after nailing. Even in the “Single sequential actuation” mode, half-pulled trigger causes an unexpected nailing, when the contact element re- contacts the workpiece.15 Contact actuation Pull the trigger first and then place the contact element against the workpiece. (Fig. 13) Jammed nailer (Fig. 14) CAUTION:

• Always disconnect the air hose and remove the nails from the magazine before cleaning a jam. When the nailer becomes jammed, do as follows: Open the 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. Nails 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. (Fig. 15) Avoid storing nails in a very humid or hot place or place exposed to direct sunlight. (Fig. 16) MAINTENANCE CAUTION:

• Always disconnect the air hose from the tool before attempting to perform inspection or maintenance.

• Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result. Maintenance of nailer Always check the tool for its overall condition and loose screws before operation. Tighten as required. (Fig. 17) 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. (Fig. 18) 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. (Fig. 19 & 20) 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. (Fig. 21 & 22) 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. (Fig. 23) 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. (Fig. 24) To maintain product SAFETY and RELIABILITY, repairs, any other maintenance or adjustment should be per- formed by Makita Authorized Service Centers, always using Makita replacement parts.
