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
actuation by actuation mode selectors or is a
contact actuation
contact tool and has been marked with the
symbol above. Its intended uses are for
production applications
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
1. 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.
2. Ask Makita authorized
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.

PARTS DESCRIPTION (Fig. 1)
INSTALLATION
Selecting compressor (Fig. 2 & 3)
Select a compressor that has ample pressure and air
output to assure cost-efficient operation. The graph
shows the relation
applicable pressure and compressor air output.
Thus, for example, if stapling takes place at a rate of
approximately 60 times per minute at a compression of
0.68 MPa (6.8 bar), a compressor with an air output over
90 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. 4)
Use an air hose as large and as short as possible to
assure continuous, efficient stapling 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 (66 ft.) is recommended when the interval
between each stapling is 0.5 seconds. Air supply hoses
shall have a minimum working pressure rating of
1.0 MPa (10 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 stapling frequency
may cause a decrease in the driving capability of the
tool.
Lubrication (Fig. 5)
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
50 staples.
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.

FUNCTIONAL DESCRIPTION

CAUTION:
for
• Always disconnect the hose before adjusting or
checking function on the tool.
Adjusting depth of stapling
To adjust the depth of stapling, loosen the bolt by using
the hex wrench provided with the tool and then slide the
depth adjusting plate up or down. (Fig. 6)
If staples cannot be driven deep enough, slide the
adjusting plate in the direction of arrow as shown in the
figure. (Fig. 7)
