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 200

PSIG (13.6 bar).

13. Never use the tool with other than compressed

air. If bottled gas (carbon dioxide, oxygen, nitro-

gen, 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 oper-

ate if only the trigger is pulled or if only the con-

tact 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 opera-

tions 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 compres-

sor 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 ejec-

tion port area.

25. When the air hose is connected, do not carry the

tool with your finger on the trigger or hand it bar)

to someone in this condition. Accidental firing

can be extremely dangerous.

26. Handle the tool carefully, as there is high pres-

sure 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 condi-

tion. 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 ele-

ment depressed with tape or wire. Death or seri-

ous 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 peri-

odical 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.

SAVE THESE INSTRUCTIONS.

WARNING:

MISUSE or failure to follow the safety rules stated in

this instruction manual may cause serious personal

injury.

TRIGGERING DEVICES

This fastener driving tool is operated by actuating the

trigger using finger pressure.

Some fastener driving tools are fitted with an additional

safety yoke which enables the driving operation to be

carried out only after the muzzle of the tool is pressed

against a workpiece. These tools are marked with an

inverted triangle (V) and may not be used unless fitted

with an effective safety yoke.

ACTUATING SYSTEMS

Depending on their purpose, fastener driving tools may

be fitted with different actuating systems. See the respec-

tive technical data sheet for details of the actuating sys-

tem of the tools.

Single sequential actuation (preferred version):

actuating system in which the safety yoke and the trigger

have to be activated in such a way that one single driving

operation is actuated via the trigger after the muzzle of the

tool has been applied to the driving location. Thereafter

any further driving operations can only be actuated after

the trigger has been returned to the starting position.

Full sequential actuation: This is an actuating system

in which the safety yoke and the trigger have to be acti-

vated in such a way that one single driving operation is

actuated via the trigger after the muzzle of the tool has

been applied to the driving location. Thereafter any fur-

ther driving operations can only be actuated only after

the trigger and the safety yoke have been returned to the

starting position.
