When the reversing switch lever is in the neutral position,
the switch trigger cannot be pulled.
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.
Speed change (Fig. 5)
To change the speed, first switch off the tool and then
slide the speed change lever to the “2” side for high speed
or “1” side for low speed. Be sure that the speed change
lever is set to the correct position before operation. 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 halfway between the “1” side and “2”
side, the tool may be damaged.
• Do not use the speed change lever while the tool is
running. The tool may be damaged.
Adjusting the fastening torque (Fig. 6)
The fastening torque can be adjusted in 17 steps by
turning 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, and maximum when the marking is aligned with
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 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.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before carrying out any
work on the tool.
Installing or removing driver bit or drill bit
(Fig. 7)
Turn the sleeve counterclockwise to open the chuck jaws.
Place the bit in the chuck as far as it will go. Turn the
sleeve clockwise to tighten the chuck.
To remove the bit, turn the sleeve counterclockwise.
Installing bit holder (Optional accessory)
(Fig. 8)
Fit the bit holder into the protrusion at the tool foot on
either right or left side and secure it with a screw.
When not using the driver bit, keep it in the bit holders.
Bits 45 mm long can be kept there.
Hook (Optional accessory) (Fig. 9)
The hook is convenient for temporarily hanging the tool.
This can be installed on either side of the tool.
To install the hook, insert it into a groove in the tool
housing on either side and then secure it with a screw.
To remove, loosen the screw and then take it out.
OPERATION
CAUTION:
• Always insert the battery cartridge all the way until it
locks in place. If you can see the red part on the upper
side of the button, it is not locked completely. Insert it
fully until the red part cannot be seen. If not, it may
accidentally fall out of the tool, causing injury to you or
someone around you.
Hold the tool firmly with one hand on the grip and the
other hand on the bottom of the battery cartridge to
control the twisting action.
Screwdriving operation (Fig. 10)
CAUTION:
• Adjust the adjusting ring to the proper torque level for
your work.
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 switch trigger
as soon as the clutch cuts in.
CAUTION:
• Make sure that the driver bit is inserted straight in the
screw head, or the screw and/or bit may be damaged.
NOTE:
• When driving wood screws, predrill pilot holes to make
driving easier and to prevent splitting of the workpiece.
See the chart.
Drilling operation
First, turn the adjusting ring so that the pointer points to
the marking. Then proceed as follows.
Drilling in wood
When drilling in wood, the best results are obtained with
wood drills equipped with a guide screw. The guide screw
makes drilling easier by pulling the bit into the workpiece.
Drilling in metal
To prevent the bit from slipping when starting a hole,
make an indentation with a center-punch and hammer at
the point to be drilled. Place the point of the bit in the
indentation and start drilling.
