Conditioning charge
Conditioning charge can extend the life of battery by automatically searching the optimum charging condition for the
batteries in every situation.
The battery employed in the following conditions repeatedly, will be worn out shortly, and yellow warning light may
flash.
1. Recharge of battery with its high temperature
2. Recharge of battery with its low temperature
3. Recharge of full charged battery
4. Over-discharge of battery (continue to discharge battery in spite of down of power.)
The charging time of such battery is longer than usual.
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.
Adjusting 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 counter-clockwise and slide the shoe for-
ward 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.
To prevent the switch trigger from being accidentally
pulled, a lock-off button is provided.
To start the tool, press in the lock-off button and pull the
switch 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 switch trigger. Release the
switch trigger to stop.
Speed change (Fig. 5)
CAUTION:
• Always set the speed change lever fully to the correct
position. If you operate the tool with the speed change
lever positioned half-way, the tool may be damaged.
• Do not use the speed change lever while the tool is
running. The tool may be damaged.
To change the speed, first switch off the tool and then
slide the speed change lever to the A side (2) for high
speed or B side (1) for low speed. Be sure that the speed
change lever is set to the correct position before opera-
tion. Use the right speed for your job.

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 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. 6)
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. 7)
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. 8)
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.
