Tips for maintaining maximum battery life
1. Charge the battery cartridge before completely
discharged.
Always stop machine operation and charge the
battery cartridge when you notice less machine
power.
2. Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life.
3. Charge the battery cartridge with room tempera-
ture at 10°C – 40°C (50°F – 104°F).
Let a hot battery cartridge cool down before
charging it.
Installing or removing depressed center
wheel (Fig. 3 & 4)
Important:
Always be sure that the machine is switched off and
the battery cartridge is removed before installing or
removing the wheel.
Fit the wheel and outer flange onto the spindle and
temporarily secure with the screw.
To tighten the screw, press the shaft lock firmly so that
the spindle cannot revolve, then use the hex wrench
to securely tighten the screw clockwise.
To remove the wheel, follow the installation procedure
in reverse.
Hex wrench storage (Fig. 5)
When not in use, the hex wrench can be conveniently
stored.
Switch action (Fig. 6)
To start the machine, simply press the switch button.
Release the switch button to stop. For continuous
operation, press the switch button fully, then release
it. To stop the machine from the locked position, press
the switch button fully again, then release it.
CAUTION:
Before inserting the battery cartridge into the
machine, be sure the switch button actuates properly.
Sharpening with depressed center wheel
(Fig. 7)
Hold the machine firmly. Turn the machine on and
then apply the wheel to the workpiece so that the
wheel and blade angle are parallel. Move the wheel
constantly in the direction shown in Fig. 7, so that
grinding action will be even.
WARNING:
• It should never be necessary to force the machine.
Forcing and excessive pressure could cause dan-
gerous wheel breakage.
• Continued use of a worn-out wheel may result in
wheel explosion and serious personal injury.
Depressed center wheel should not be used after it
has been worn down to 75 mm in diameter. Use of
the wheel after this point is unsafe and it should be
removed from service and rendered unusable by
intentional destruction.
MAINTENANCE
CAUTION:
Always be sure that the machine is switched off and
the battery cartridge is removed before carrying out
any work on the machine.
To maintain product safety and reliability, repairs,
maintenance or adjustment should be carried out by a
Makita Authorized Service Center.
