Makita DJR143 Manuel D'instructions page 7

To prevent the switch lever/trigger from accidentally
pulled, the lock-off lever/button are provided.
To start the tool, pull either switch lever or trigger.
• For the switch lever, pull the lock-off lever and then pull
the switch lever to start the tool.
• For the switch trigger, depress the lock-off button and
then pull the switch trigger to start to the tool. The lock-
off button can be pressed from either right or left.
The tool speed is increased by increasing pressure on the
switch lever/trigger. Release the switch lever/trigger to
stop.
NOTICE:
Do not pull the switch lever/trigger hard without pulling the
lock-off lever/button. This can cause switch breakage.
Lighting up the front lamp (Fig. 4)
CAUTION:
• Do not look in the light or see the source of light
directly.
Pull the switch lever/trigger to light up the lamp. The lamp
keeps on lighting while the switch lever/trigger is being
pulled.
The lamp automatically turns off 10-15 seconds after
releasing the switch lever/trigger.
Adjusting the shoe (Fig. 5)
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 bolt with hex wrench.
Slide the shoe to the desired position and then tighten the
bolt firmly.
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.
For Model DJR143, DJR183 (Fig. 6)
Insert the recipro saw blade into the blade clamp as far as
it will go. The blade clamp sleeve rotates and fixes the
saw blade. Make sure that the saw blade cannot be
extracted even though you try to pull it out.
CAUTION:
• If you do not insert the saw blade deep enough, the
saw blade may be ejected unexpectedly during
operation. This can be extremely dangerous.
NOTE:
• You can not use the jig saw blade with DJR143 or
DJR183. (Fig. 7)
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.
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.
For Model DJR145, DJR185 (Fig. 8 & 9)
To install the saw blade, loosen the bolt by hex wrench.
When installing a recipro saw blade, press the bolt with
the hex wrench to open the slot during inserting the blade.
(Fig. 10 & 11)
You can use both jig saw blades (B type) and recipro saw
blades according to your work. Insert the saw blade
straight into the blade clamp and tighten it by hex wrench.
Pull the saw blade lightly to make sure that the saw blade
does not fall off during operation.
To remove the saw blade, follow the installation
procedure in reverse.
Hex wrench storage (Fig. 12)
When not in use, store the hex wrench as shown in the
figure to keep it from being lost.
OPERATION
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. (Fig. 13)
Press the shoe firmly against the workpiece. Do not allow
the tool to bounce. Bring the saw blade into light contact
with the workpiece. First, make a pilot groove using a
slower speed. Then use a faster speed to continue
cutting. (Fig. 14 & 15)
• You can use the switch lever or trigger according to
your work.
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.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized Service Centers, always
using Makita replacement parts.
