WARNING:
MISUSE or failure to follow the safety rules stated in
this instruction manual may cause serious personal
injury.
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, pull out the set plate
on the tool and grasp both sides of the cartridge while
withdrawing it from the tool.
• To insert the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Snap the set plate back into place. Be sure
to close the set plate fully before using the tool.
• Do not use force when inserting the battery cartridge. If
the cartridge does not slide in easily, it is not being
inserted correctly.
Installing or removing driver bit or drill bit (Fig. 2)
Important:
Always be sure that the tool is switched off and the bat-
tery cartridge is removed before installing or removing
the bit.
Hold the ring and turn the sleeve counterclockwise to
open the chuck jaws. Place the bit in the chuck as far as
it will go. Hold the ring firmly and turn the sleeve clock-
wise to tighten the chuck.
To remove the bit, hold the ring and turn the sleeve coun-
terclockwise.
Switch action (Fig. 3)
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.
Move the reversing switch lever to the A position for
clockwise rotation or the B position for counterclockwise
rotation. When the reversing switch lever is in the neutral
position, the tool will not start even if you pull the trigger.
Speed change (Fig. 4)
To change the speed, first switch off the tool and then
slide the speed change lever to the "ΙΙ" side for high
speed or "Ι" 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 "Ι" side and
"ΙΙ" side, the tool may be damaged.
• Do not use the speed change lever while the tool is run-
ning. The tool may be damaged.
Adjusting the fastening torque (Fig. 5)
The fastening torque can be adjusted in 17 steps by turn-
ing the adjusting ring so that its graduations are aligned
with the pointer on the tool body. The fastening torque is
minimum when the number 1 is aligned with the pointer,
A
and maximum when the
pointer.
The clutch will slip at various torque levels when set at
the number 1 to 16. The clutch is designed not to slip at
A
the
marking.
Before actual operation, drive a trial screw into your
material or a piece of duplicate material to determine
which torque level is required for a particular application.
NOTE:
• The adjusting ring does not lock when the pointer is
positioned only half-way between the graduations.
• Do not operate the tool with the adjusting ring set
between the number 16 and the
may be damaged.
Screwdriving operation (Fig. 6)
Place the point of the driver bit in the screw head and
apply pressure to the tool. Start the tool slowly and then
increase the speed gradually. Release the trigger as
soon as the clutch cuts in.
NOTE:
• Make sure that the driver bit is inserted straight in the
screw head, or the screw and/or bit may be damaged.
• When driving wood screws, predrill pilot holes to make
driving easier and to prevent splitting of the workpiece.

15 minutes before proceeding with a fresh battery.
Drilling operation
First, turn the adjusting ring so that the pointer on the tool

body points to the
marking. Then proceed as follows.
• Drilling in wood
When drilling in wood, best results are obtained with
wood drills equipped with a guide screw. The guide
screw makes drilling easier by pulling the bit into the
