Operation; Maintenance - Makita DJR141 Instruction Manual

Adjusting the shoe
Fig.3
When the blade loses its cutting efficiency in one place
along its cutting edge, reposition the shoe to utilize a
sharp, unused portion of its cutting edge. This will help to
lengthen the life of the blade. To reposition the shoe,
loosen the lever counterclockwise and slide the shoe
forward or back to the desired position. Then tighten the
lever clockwise to firmly secure the shoe.
Switch action
Fig.4
CAUTION:
Before inserting the battery cartridge into the tool,
•
always check to see that the switch trigger
actuates properly and returns to the "OFF" position
when released.
When not operating the tool, depress the lock-off
•
button from A side to lock the switch trigger in the
OFF position.
To prevent the switch trigger from accidentally pulled,
the lock-off button is provided.
To start the tool, depress the lock-off button from B side
and pull the switch trigger.
Tool speed is increased by increasing pressure on the
switch trigger. Release the switch trigger to stop. After
use, always press in the lock-off button from A side.
ASSEMBLY
CAUTION:
Always be sure that the tool is switched off and the
•
battery cartridge is removed before carrying out
any work on the tool.
Installing or removing the saw blade
CAUTION:
Always clean out all chips or foreign matter
•
adhering to the blade, blade clamp and/or slider.
Failure to do so may cause insufficient tightening
of the blade, resulting in a serious injury.
To install the saw blade, always make sure that the
blade clamp sleeve is in released position before
inserting the saw blade. If the blade clamp sleeve is in
fixed position, rotate the sleeve to the released position.
Fig.5
Insert the saw blade into the blade clamp as far as it will
go. The blade clamp sleeve rotates and the saw blade is
fixed. Make sure that the saw blade cannot be extracted
even though you try to pull it out.
Fig.6
NOTE:
If you do not insert the saw blade deep enough, the
•
saw blade may be ejected unexpectedly during
operation. This can be extremely dangerous.
To remove the saw blade, rotate the blade clamp sleeve
in the direction of the arrow fully. The saw blade is
removed and the blade clamp sleeve is fixed at the
released position.
Fig.7
NOTE:
If you remove the saw blade without rotating the
•
blade clamp sleeve fully, the sleeve may not be
fixed. In this case, rotate the blade clamp sleeve
fully, then make the sleeve fixed at the released
position.

OPERATION

Fig.8
CAUTION:
Always press the shoe firmly against the workpiece
•
during operation. If the shoe is held away from the
workpiece during operation, strong vibration and/or
twisting will be produced, causing the blade to
snap dangerously.
Always wear gloves to protect your hands from hot
•
flying chips when cutting metal.
Be sure to always wear suitable eye protection
•
which conforms with current national standards.
Always use a suitable coolant (cutting oil) when
•
cutting metal. Failure to do so will cause premature
blade wear.
If the tool is operated continuously until the battery
•
cartridge has discharged, allow the tool to rest for
15 minutes before proceeding with a fresh battery.
Press the shoe firmly against the workpiece. Do not allow
the tool to bounce. Bring the blade into light contact with
the workpiece. First, make a pilot groove using a slower
speed. Then use a faster speed to continue cutting.
NOTE:
If the tool is operated continuously until the battery
•
cartridge has discharged, allow the tool to rest for
15 minutes before proceeding with a fresh battery.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and the
•
battery cartridge is removed before attempting to
perform inspection or maintenance.
Never use gasoline, benzine, thinner, alcohol or
•
the like. Discoloration, deformation or cracks may
result.
Replacing carbon brushes
Fig.9
Remove and check the carbon brushes regularly.
Replace when they wear down to the limit mark. Keep
the carbon brushes clean and free to slip in the holders.
Both carbon brushes should be replaced at the same
time. Use only identical carbon brushes.
