Functional Description - Makita AN450H Bedienungsanleitung

Thus, for example, if nailing takes place at a rate of
approximately 50 times per minute at a compression of
1.76 MPa (17.6 bar), a compressor with an air output
over 90 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.1
Use a high pressure resistant air hose.
Use an air hose as large and as short as possible to
assure continuous, efficient nailing operation.
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
Fig.2
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.

FUNCTIONAL DESCRIPTION

CAUTION:
Always disconnect the air hose before adjusting or
•
checking function on the tool.
Adjusting depth of nailing
Fig.4
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 shallower 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. Generally 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 disconnect the hose before adjusting the
•
depth of nailing.
Hook
Fig.5
CAUTION:
Always 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.
Adjusting the shingle guide
Fig.6
Fig.7
The shingle guide is designed for consistent shingle
exposure. Place shingle in desired position.
Turn the lever clockwise to release the adjusting plate.
Reset the tool on the exposed shingle with the
projections of the contact element depressing the
bottom of the previous row of the shingle. Slide the
adjusting plate up against the bottom of the exposed
shingle and turn the lever counterclockwise to lock the
adjusting plate.
ASSEMBLY
CAUTION:
Always disconnect the air hose before carrying out
•
any work on the tool.
Loading nailer
Fig.8
Select nails suitable for your work. Depress the latch
lever and open the magazine cap.
Lift and turn the coil support plate so that the arrow with
nail size indicated on the coil support plate will point to
the corresponding graduation increment marked on the
magazine. If the tool is operated with the coil support
plate set to the wrong step, poor nail feed or malfunction
of the tool may result.
Fig.9
Place the nail coil over the coil support plate. Uncoil
enough nails to reach the feed claw. Place the first nail in
the driver channel and the second nail in the feed claw.
Place other uncoiled nails on feeder body. Close the
magazine cap after checking to see that the nail coil is
set properly in the magazine.
Fig.10
Connecting air hose
Fig.11
Slip the air socket of the air hose onto the air fitting on
the nailer. Be sure that the air socket locks firmly into
position when installed onto the air fitting. A hose
coupling must be installed on or near the tool in such a
way that the pressure reservoir will discharge at the time
the air supply coupling is disconnected.
