Installation - Makita AT638A Instruction Manual

17. Never attempt to drive fasteners from both the
inside and outside at the same time. Fasteners
may rip through and/or fly off, presenting a grave
danger.
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.

1. Stapling frequency (times/min) 2. Compressor air
output per minute (L/min) 3. 0.83 MPa (8.3 bar) 4. 0.66
MPa (6.6 bar) 5. 0.49 MPa (4.9 bar)
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 stapling frequency, applica-
ble 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 0.83 MPa (8.3 bar), a compressor with an air output
over 50 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 stapling frequency may cause a decrease in
the driving capability of the tool.
