Operation; Maintenance - Makita BJR181 Betriebsanleitung

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 but-
ton 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.
Lighting up the front lamp (Fig. 5)
CAUTION:
• Do not look in the light or see the source of light
directly.
Pull the switch trigger to light up the lamp. The lamp
keeps on lighting while the switch trigger is being pulled.
The light automatically goes out 10 - 15 seconds after the
switch trigger is released.
NOTE:
• Use a dry cloth to wipe the dirt off the lens of lamp. Be
careful not to scratch the lens of lamp, or it may lower
the illumination.
Hook (Fig. 6)
CAUTION:
• Depress the lock-off button from A side to lock the
switch trigger in the OFF position. (See the section
titled "switch action".)
• Never hook the tool at high location or on potentially
unstable surface.
The hook is convenient for hanging the tool temporarily.
To use the hook, simply lift up hook until it snaps into the
open position.
When not in use, always lower hook until it snaps into the
closed position.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and the bat-
tery 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 lever is in released position
cover before inserting the saw blade. If the blade clamp
lever is in fixed position, rotate the blade clamp lever in
the direction of the arrow so that it can be locked at the
released position . (Fig. 7)
Insert the saw blade into the blade clamp as far as it will
go. The blade clamp lever 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. 8)
NOTE:
• If you do not insert the saw blade deep enough, the
saw blade may be ejected unexpectedly during opera-
tion. This can be extremely dangerous.
To remove the saw blade, rotate the blade clamp lever in
the direction of the arrow fully. The saw blade is removed
and the blade clamp lever is fixed at the released position
. (Fig. 9)
NOTE:
• If you remove the saw blade without rotating the blade
clamp lever fully, the lever may not be locked in the
released position
clamp lever fully again, then make sure that the blade
clamp lever locked at the released position

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 fly-
ing 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.
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
aster speed to continue cutting. (Fig. 10)

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and the bat-
tery cartridge is removed before attempting to perform
inspection or maintenance.
Replacing carbon brushes
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. (Fig. 11)
