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.
-
For personal safety and proper operation and maintenance of the tool, read this instruction manual before using the tool.
-
Always wear safety glasses to protect your eyes from dust or nail injury.
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.
-
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:
- Always assume that the tool contains fasteners.
- 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 trigger.
- Do not load the tool with fasteners when any one of the 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.
-
Operate the tool within the specified air pressure of 0.49 – 0.83 MPa (4.9 – 8.3 bar) for safety and longer tool life. Do not exceed the recommended max. operating pressure of 0.83 MPa (8.3 bar). The tool should not be connected to a source whose pressure potentially exceeds 1.37 MPa (13.7 bar).
-
Make sure that the pressure supplied by the compressed air system does not exceed the maximum allowable pressure of the fastener driving tool. Set the air pressure initially to the lower value of the recommended allowable pressure (see SPECIFICATIONS).
-
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.
-
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;
– fitting 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, and secure the air hose 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 nailing 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 tool itself can react dangerously. Place the nails with care.
-
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.
-
Do not point the ejection port at anyone in the vicinity. Keep hands and feet away from the ejection port area.
-
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.
-
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 nailing operations immediately if you notice something wrong or out of the ordinary with the tool.
-
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.
4. 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 frictionrelated 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.
-
Use only pneumatic tool oil specified in this manual.
-
Never connect the tool to compressed air line where the air pressure can exceed the suitable air pressure range of the tool, specified in the “SPECIFICATIONS” table, by 10%.
-
Fastener driving tools operated by compressed air should only be operated at the lowest pressure required for the work process at hand, in order to prevent unnecessarily high noise levels, increased wear and resulting failures.
-
Do not attempt to keep the trigger or contact element depressed with tape or wire. Death or serious injury may occur.
-
Always check contact element as instructed in this manual. Nails may be driven accidentally if the safety mechanism is not working correctly.
SAVE THESE INSTRUCTIONS.
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. 1)
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 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 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. 2)
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. (Fig. 3)
FUNCTIONAL DESCRIPTION
CAUTION:
• Always disconnect the air hose before adjusting or checking function on the
tool.
Adjusting depth of nailing (Fig. 4)
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. 5)
CAUTION:
• Always disconnect the hose before installing or removing 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. 6)
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. 7)
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. 8)
Connecting air hose (Fig. 9)
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.
OPERATION
CAUTION:
• Make sure all safety systems are in working order before operation.
For continuous nailing mode
Rotate the lever to the position while pressing the button on the other side
of the lever. (Fig. 10 & 11)
- To drive a nail, you may place the contact element against the workpiece and pull the trigger.
- Pull the trigger first and then place the contact element against the workpiece.
• 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:
• Operating the tool without nails shortens the life of the tool and should be
avoided.
For sequential mode (intermittent nailing mode) (Fig. 12)
Rotate the lever to the position while pressing the button on the other
side of the lever.
To drive a nail, you may place the contact element against the workpiece and
pull the trigger.
CAUTION:
• WITH THE TRIGGER HELD IN A HALF-PULLED POSITION, an unexpected nailing could
occur, if contact element is allowed to re-contact against the workpiece or
the other sueface 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.
• Operating the tool without nails shortens the life of the tool and should be
avoided.
Jammed nailer (Fig. 13)
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. 14) Avoid storing nails in a very humid or hot place or place
exposed to direct sunlight. (Fig. 15)
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. 16) 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.
17)
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. 18 &
19)
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. 20 & 21)
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. 22)
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. 23)
To maintain product SAFETY and RELIABILITY, repairs, any other maintenance or adjustment should be performed by Makita Authorized Service Centers, always using Makita replacement parts.
