Makita replacement parts.
• Use only pneumatic tool oil specified in this man-
ual.
• Never connect tool to compressed air line where
the maximum allowable pressure of tool cannot be
exceeded by 10 %. Make sure that the pressure
supplied by the compressed air system does not
exceed the maximum allowable pressure of the fas-
tener driving tool. Set the air pressure initially to
the lower value of the recommended allowable
pressure.
• Do not attempt to keep the trigger 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.

INSTALLATION
Selecting compressor (Fig. 1)
• Select a compressor that has ample pressure and air
output to assure cost-efficient 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 approxi-
mately 40 times per minute at a compression of
0.59 MPa (5.9 bar), a compressor with an air output
over 3 CFM (ft
3
/minute) is required. Pressure regula-
tors must be used to limit air pressure to the rated pres-
sure 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
internal diameter of over 8.5 mm (5/16”) and a length of
less than 20 m (6.6 ft.) is recommended when the inter-
val 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. 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 lock the trigger and disconnect the hose before
adjusting or checking function on the tool.
Nose adapter (Accessory) (Fig.5)
CAUTION:
• Always lock the trigger and disconnect the hose before
installing or removing the nose adapter.
When nailing workpieces with easily-marred surfaces, use
the nose adapter.
Attach the nose adapter to the contact arm.
Adjusting depth of nailing (Fig. 6)
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 shal-
lower 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. Gener-
ally 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 lock the trigger and disconnect the hose before
adjusting the depth of nailing.
Hook (Fig. 7)
CAUTION:
• Always lock the trigger and disconnect the hose from
the tool.
• Never hook the tool at high location or on potentially
unstable surface.
The hook is convenient for hanging the tool temporarily.
To use the hook, simply lift up hook until it snaps into the
open position.
When not in use, always lower hook until it snaps into the
closed position.
ASSEMBLY
CAUTION:
• Always lock the trigger and disconnect the hose before
carrying out any work on the tool.
Loading nailer
Select nails suitable for your work. Insert strip of nails into
the magazine.
(Fig. 8)
Pull the pusher lever to the rear to engage the pusher to
the last nail.
(Fig. 9)
Unloading nailer
Pull the pusher lever to the rear. Return the pusher lever
back while keeping the pusher depressed to disengage it
from the strip of nails.
