pressor 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 y o󰀨, presenting a grave danger. Repetitive motions hazards

1. When using a tool for long periods, the oper-

ator 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 o󰀨-bal- anced postures.

3. If the operator experiences symptoms such

as persistent or recurring discomfort, pain, throbbing, aching, tingling, numbness, burn- ing sensation, or sti󰀨ness, do not ignore these warning signs. The operator should consult a qualied health professional regarding overall activities.

4. The continuous use of the tool may cause

repetitive strain 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 repeti-

tive motion hazards. It should focus on mus- cular-skeletal disorders and be preferentially based on the assumption that decreasing fatigue during work is e󰀨ective 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 work- piece 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 work-

place injury. Be aware of slippery surfaces caused by use of the tool and also of trip haz- ards 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 dam- aged 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.8 ENGLISH

2. Direct the exhaust so as to minimize distur-

bance of dust in a dust lled 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, buzz- ing, whistling or humming in the ears).

2. Conduct a risk assessment regarding noise

hazards in the work area and implement appro- priate 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 recom-

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

6. Take noise reduction measures, for exam-

ple 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 assess- ment regarding vibration hazards and imple- ment 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.

If you experience numbness, tingling, pain or whitening of the skin in your ngers or hands, seek medical advice from a qualied occupational health professional regarding overall activities.

5. Operate and maintain the tool as recom-

mended 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 o󰀨 air supply, and disconnect tool

from air supply when not in use.

3. Always disconnect the tool from the com-

pressed air supply before changing acces- sories, making adjustments and/or repairs, when moving away from an operating area to a di󰀨erent area.

4. Keep ngers 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 ttings.

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 oper-

ating pneumatic tools creates a re and explo- sion hazard.

12. Be careful when using pneumatic tools as the

tool could become cold, a󰀨ecting grip and control. Additional warnings for tools with contact actuation capability

1. Do not rest your nger on the trigger when

picking up the tool, moving between operating areas and positions or walking, as resting nger on trigger can lead to inadvertent opera- tion. 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 con-

tact 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 applica- tions 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 tting 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 oper- ate 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 acci- dentally if the safety mechanism is not working correctly.9 ENGLISH Service

MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury. PARTS DESCRIPTION ► Fig.1: 1. Trigger 2. Contact element 3. Actuation mode selector 4. Magazine 5. Hook INSTALLATION Selecting compressor

1. Nailing frequency (times/min) 2. Compressor air

output per minute (L/min) 3. 0.83 MPa (8.3 bar) 4. 0.66 MPa (6.6 bar) 5. 0.49 MPa (4.9 bar) 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-e󰀩cient operation. The graph shows the relation between nailing frequency, applica- ble pressure and compressor air output. Thus, for example, if nailing takes place at a rate of approximately 60 times per minute at a compression of 0.83 MPa (8.3 bar), a compressor with an air output over 110 liters/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 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. ► Fig.2 Use an air hose as large and as short as possible to assure continuous, e󰀩cient nailing operation. With an air pressure of 0.49 MPa (4.9 bar), an air hose with an internal 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 minimum working pres- sure rating of 1.03 MPa (10.3 bar) or 150 percent of the maximum pressure produced in the system whichever is higher. Lubrication ► Fig.3 To insure maximum performance, install an air set (oiler, regulator, air lter) 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 tting. This should be done before and after use. For proper lubrication, the tool must be red a couple of times after pneumatic tool oil is introduced. ► Fig.4: 1. Pneumatic tool oil10 ENGLISH FUNCTIONAL DESCRIPTION CAUTION: Before adjusting or checking func- tion on the tool, always release the trigger and disconnect the air hose from the tool. Adjusting depth of nailing CAUTION: Always release the trigger and disconnect the hose before adjusting the depth of nailing. ► Fig.5: 1. Adjuster 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 gure. 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 deeper depth of nail driving. Hook CAUTION: Always release the trigger and disconnect the hose before changing the hook position. CAUTION: Never hook the tool at high loca- tion or on potentially unstable surface. CAUTION: Do not hang the hook from the waist belt. If the nailer accidentally drops, it may result in misring and personal injuries. ► Fig.6 ► Fig.7: 1. Hook 2. Hex socket bolt 3. Hole The hook is convenient for hanging the tool temporarily. To change the hook position, remove the hex socket bolt and switch the hook direction. The hook has two holes. Choose the hole depending on your preferable hook width. Adjusting the shingle guide ► Fig.8: 1. Contact element 2. Shingle guide

► Fig.9: 1. Adjusting plate 2. Lever The shingle guide is designed for consistent shingle exposure. Place shingle in desired position. Turn the lever to release the adjusting plate. Set the nailer so that the contact element will depress both the exposed shingle and previous row of the shingle. Slide the adjusting plate up against the bottom of the exposed shingle and return the lever to lock the adjusting plate. ASSEMBLY CAUTION: Before carrying out any work on the tool, always release the trigger and discon- nect the air hose from the tool. CAUTION: Load the same type, size and uniform length of nails when loading nails in the magazine. Loading nailer NOTICE: Select nails suitable for your work. NOTICE: Set the coil support plate according to the nail size to be used. 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.

cap. ► Fig.10: 1. Magazine cap 2. Latch lever

2. 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. ► Fig.11: 1. Coil support plate 2. Graduation 3. Arrow

3. Place the nail coil over the coil support plate.

Uncoil enough nails to reach the feed claw. Place the rst 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.12: 1. Feed Claw Connecting air hose CAUTION: Do not rest your nger on the trigger when connecting the air hose. ► Fig.13: 1. Air tting 2. Air socket Slip the air socket of the air hose onto the air tting on the tool. Be sure that the air socket locks rmly into position when installed onto the air tting. 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. OPERATION CAUTION: Make sure all safety systems are in working order before operation.11 ENGLISH Checking proper action before operation Before operation, always check following points. — Make sure that the tool does not operate only by connecting 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 placing 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 rst and then placing the contact element against the workpiece. Selecting the operation mode CAUTION: Always make sure that the actua- tion mode selector is properly set to the position for the desired nailing mode before nailing. ► Fig.14: 1. Actuation mode selector Single sequential actuation mode: You can drive one nail by one sequential operation. Select this mode when driving a nail carefully and accurately. To choose this mode, set the actuation mode selector to the position. Contact actuation mode: You can drive nails repetitively by placing the contact element with the trigger held. To choose this mode, set the actuation mode selector to the position. Single sequential actuation 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. Place the contact element against the workpiece and pull the trigger fully. After nailing, release the contact element, and then release the trigger. ► Fig.15 Contact actuation Pull the trigger rst and then place the contact element against the workpiece. ► Fig.16 Removing jammed nails CAUTION: Always release the trigger and dis- connect the hose before removing jammed nails. CAUTION: Do not use deformed nails or nail strip. Failure to do so causes poor nail feeding. ► Fig.17: 1. Hammer 2. Small rod 3. Ejection port 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. MAINTENANCE CAUTION: Before attempting to perform inspection or maintenance, always release the trigger and disconnect the air hose from the tool. NOTICE: Never use gasoline, benzine, thinner, alcohol or the like unless otherwise instructed in this manual. Discoloration, deformation or cracks may result. Nails Handle nail coils and their box carefully. If the nail coils have been handled roughly, they may be out of shape, causing poor nail feed. Avoid storing nails in a very humid or hot place or place exposed to direct sunlight. Cleaning and removal of tar and dirt CAUTION: Always wear waterproof gloves to protect your hands. Adhesion of tar and dirt to areas around the contact element will prevent smooth movement of the contact element (safety mechanism), causing accidental dis- charge. 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. ► Fig.18 NOTICE: Never immerse the housing, magazine, etc. in solvent. Malfunction of the tool may result. NOTE: Always dispose of the solvent used in a safe and prudent manner and in compliance with all local and national code requirement.12 ENGLISH Maintenance of nailer Always check the tool for its overall condition and loose screws before operation. Tighten as required. 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. 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 Maintenance of compressor, air set and air hose After operation, always drain the compressor tank and the air lter. If moisture is allowed to enter the tool, it may result in poor performance and possible tool failure. ► Fig.20: 1. Drain cock ► Fig.21: 1. Air lter Check regularly to see if there is su󰀩cient pneumatic tool oil in the oiler of the air set. Failure to maintain su󰀩- cient lubrication will cause O-rings to wear quickly. ► Fig.22: 1. Oiler 2. Pneumatic tool oil 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. 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.
