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.
Service
1. 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.
2. Ask Makita authorized service center for peri-
odical 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.
SAVE THESE INSTRUCTIONS.
WARNING:
DO NOT let comfort or familiarity
with product (gained from repeated use) replace
strict adherence to safety rules for the subject
product. MISUSE or failure to follow the safety
rules stated in this instruction manual may cause
serious personal injury.

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, applica-
ble pressure and compressor air output.
Thus, for example, if nailing takes place at a rate of
approximately 40 times per minute at a compression
of 0.66 MPa (6.6 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, 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 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 filter) 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
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.
