Maintenance - Makita JR180D Betriebsanleitung

Trickle charge (Maintenance charge)
If you leave the battery cartridge in the charger to prevent spontaneous discharging after full charge, the charger will
switch into its "trickle charge (maintenance charge)" mode and keep the battery cartridge fresh and fully charged.
Tips for maintaining maximum battery life
1. Charge the battery cartridge before completely discharged.
Always stop tool operation and charge the battery cartridge when you notice less tool power.
2. Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life.
3. Charge the battery cartridge with room temperature at 10°C – 40°C (50°F – 104°F).
Let a hot battery cartridge cool down before charging it.
4. Charge the Nickel Metal Hydride battery cartridge when you do not use it for more than six months.
Installing or removing 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 to make the
sleeve fixed at the released position.
Adjusting the shoe (Fig. 8)
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 and slide the shoe forward or back to the
desired position. Then tighten the lever to firmly secure
the shoe.
Switch action (Fig. 9)
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.
To prevent the trigger from being accidentally pulled, a
lock-off button is provided. To start the tool, press in the
lock-off button and pull the trigger. The lock-off button
can be pressed in from either left or right side of the tool.
Tool speed is increased by increasing pressure on the
trigger. Release the trigger to stop.

Operation (Fig. 10)
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.
CAUTION:
• Always use a suitable coolant (cutting oil) when cutting
metal. Failure to do so will cause premature blade
wear.
• Always wear gloves to protect your hands from hot fly-
ing chips when cutting metal.
• 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.

MAINTENANCE

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.
Replacement of carbon brushes (Fig. 11 & 12)
Replace carbon brushes when they are worn down to the
limit mark. Both identical carbon brushes should be
replaced at the same time.
To maintain product safety and reliability, repairs, mainte-
nance or adjustment should be carried out by a Makita
Authorized Service Center.
