Maintenance - Makita AN454 Betriebsanleitung

Checking proper action before
operation
Before operation, always check following points.
— Make sure that the tool does not operate only by
connecting the air hose.
— Make sure that the tool does not operate only by
pulling the trigger.
— Make sure that the tool does not operate only by
placing the contact element against the workpiece
without pulling the trigger.
— In single sequential actuation mode, make sure
that the tool does not operate when pulling the
trigger first and then placing the contact element
against the workpiece.
Selecting the operation mode
CAUTION:
Always make sure that the actua-
tion mode selector is properly set to the position
for the desired nailing mode before nailing.
► Fig.14: 1. Actuation mode selector
Single sequential actuation mode:
You can drive one nail by one sequential operation.
Select this mode when driving a nail carefully and
accurately.
To choose this mode, set the actuation mode selector to
the position.
Contact actuation mode:
You can drive nails repetitively by placing the contact
element with the trigger held.
To choose this mode, set the actuation mode selector to
the position.
Single sequential actuation
CAUTION:
Do not place the contact element
against the workpiece with excessive force. Also,
pull the trigger fully and hold it on for 1-2 seconds
after nailing.
Even in the "Single sequential actuation" mode, half-
pulled trigger causes an unexpected nailing, when the
contact element re-contacts the workpiece.
Place the contact element against the workpiece and
pull the trigger fully.
After nailing, release the contact element, and then
release the trigger.

Removing jammed nails
CAUTION:
Always release the trigger and dis-
connect the hose before removing jammed nails.
CAUTION:
Do not use deformed nails or nail
strip. Failure to do so causes poor nail feeding.
► Fig.17: 1. Hammer 2. Small rod 3. Ejection port
When the nailer becomes jammed, do as follows: Open
the magazine cap and remove the nail coil. Insert a
small rod or the like into the ejection port and tap it
with a hammer to drive out the nail jamming from the
ejection port. Reset the nail coil and close the magazine
cap.

MAINTENANCE

CAUTION:
Before attempting to perform
inspection or maintenance, always release the
trigger and disconnect the air hose from the tool.
NOTICE:
Never use gasoline, benzine, thinner,
alcohol or the like unless otherwise instructed in
this manual. Discoloration, deformation or cracks
may result.
Nails
Handle nail coils and their box carefully. If the nail coils
have been handled roughly, they may be out of shape,
causing poor nail feed.
Avoid storing nails in a very humid or hot place or place
exposed to direct sunlight.
Cleaning and removal of tar and dirt
CAUTION:
Always wear waterproof gloves to
protect your hands.
Adhesion of tar and dirt to areas around the contact
element will prevent smooth movement of the contact
element (safety mechanism), causing accidental dis-
charge. Periodically clean the areas around the contact
element.
Use a solvent such as kerosene, #2 fuel oil or diesel
fuel. Immerse only the contact element and the areas
around the ejection port in solvent and remove tar and
dirt with brush.
► Fig.18
NOTICE:
Never immerse the housing, magazine,
etc. in solvent. Malfunction of the tool may result.
NOTE: Always dispose of the solvent used in a safe
and prudent manner and in compliance with all local
and national code requirement.
