SAVE THESE INSTRUCTIONS. OPERATING INSTRUCTIONS

Installing or removing battery cartridge (Fig .1)

• Always switch off the tool before insertion or removal of
the battery cartridge.
• To remove the battery cartridge, withdraw it from the
tool while pressing the buttons on both sides of the car-
tridge.
• To insert the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Always insert it all the way until it locks in
place with a little click. If not, it may accidentally fall out
of the tool, causing injury to you or someone around
you.
• Do not use force when inserting the batter y cartridge. If
the cartridge does not slide in easily, it is not being
inserted correctly.

Switch action (Fig. 2)

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 start the tool, simply pull the trigger. tool speed is
increased by increasing pressure on the trigger. Release
the trigger to stop.

Reversing switch action (Fig. 3)

CAUTION:
• Always check the direction of rotation before operation.
• Use the reversing switch only after the tool comes to a
complete stop. Changing the direction of rotation
before the tool stops may damage the tool.
• When not operating the tool, always set the reversing
switch lever to the neutral position.
This tool has a reversing switch to change the direction of
rotation. Depress the reversing switch lever from the A
side for clockwise rotation or from the B side for counter-
clockwise rotation. When the switch lever is in the neutral
position, the switch trigger cannot be pulled.

Speed change (Fig. 4)

To change the speed, first switch off the tool and then
slide the speed change lever to the “ II ” side for high
speed or “ I” side 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.
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 between the “ I” side an d “ II ”
side, the tool may be damaged.
• Do not use the speed change lever while the tool is run-
ning. The tool may be damaged.
