Installation - Makita AT450H Bedienungsanleitung

Service
Perform cleaning and maintenance right after
•
finishing the job. Keep the tool in tip-top condition.
Lubricate moving parts to prevent rusting and
minimize friction-related wear. Wipe off all dust
from the parts.
Ask Makita authorized service center for periodical
•
inspection of the tool.
To maintain product SAFETY and RELIABILITY,
•
maintenance and repairs should be performed by
Makita Authorized Service Centers, always using
Makita replacement parts.
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.
Before use
WARNING:
Never use the tool when the contact element does
•
not work in order.
The tool works only when the contact element is placed
against the workpiece and the trigger is pulled with the
contact element being depressed. Before use, make
sure that the contact element work in order by checking
according to the following procedure.
1. Before checking, make sure that the tool is not
loaded with staples.
2. Connect the air hose to the tool.
3. First pull the trigger only. And then release the
trigger and place the contact element against the
workpiece.

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
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
1.77 MPa (17.7 bar), a compressor with an air output
over 40 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
Fig.3
Use a high pressure resistant air hose.
Use an air hose as large and as short as possible to
assure continuous, efficient stapling operation.
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
Before and after use, oil the tool with pneumatic tool oil
by placing two or three drops into the air fitting. For
proper lubrication, the tool must be fired a couple of
times after pneumatic tool oil is introduced.
