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/drill bit
► Fig.9: 1. Sleeve 2. Close 3. Open
Turn the sleeve counterclockwise to open the chuck jaws.
Place the driver bit/drill bit in the chuck as far as it will go.
Turn the sleeve clockwise to tighten the chuck. To remove
the driver bit/drill bit, turn the sleeve counterclockwise.
Installing hook
CAUTION:
When installing the hook, always
secure it with the screw firmly. If not, the hook may
come off from the tool and result in the personal injury.
► Fig.10: 1. Groove 2. Hook 3. Screw
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.
Installing driver bit holder
Optional accessory
► Fig.11: 1. Driver bit holder 2. Driver bit
Fit the driver 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 driver bit
holders. Driver bits 45 mm-long can be kept there.
Installing side grip (auxiliary handle)
Optional accessory
► Fig.12: 1. Protrusion 2. Arm 3. Recess 4. Grip
Insert the side grip so that the protrusions on the arm fit in the
recesses on the tool. Then tighten the grip by turning clockwise.
Depending the operations, you can install the side grip
either right or left side of the tool.
OPERATION
CAUTION:
Always insert the battery cartridge
all the way until it locks in place. If you can see the
red indicator on the upper side of the button, it is not
locked completely. Insert it fully until the red indicator
cannot be seen. If not, it may accidentally fall out of the
tool, causing injury to you or someone around you.
CAUTION:
When the speed comes down
extremely, reduce the load or stop the tool to
avoid the tool damage.
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
CAUTION:
Adjust the adjusting ring to the
proper torque level for your work.
CAUTION:
Make sure that the driver bit is
inserted straight in the screw head, or the screw
and/or driver bit may be damaged.
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.
NOTE: When driving wood screw, pre-drill a pilot hole
2/3 the diameter of the screw. It makes driving easier
and prevents splitting of the workpiece.
Drilling operation
First, turn the adjusting ring so that the arrow 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 drill bit into
the workpiece.
Drilling in metal
To prevent the drill 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
drill bit in the indentation and start drilling.
Use a cutting lubricant when drilling metals. The excep-
tions are iron and brass which should be drilled dry.
CAUTION:
Pressing excessively on the tool
will not speed up the drilling. In fact, this excessive
pressure will only serve to damage the tip of your drill
bit, decrease the tool performance and shorten the
service life of the tool.
CAUTION:
Hold the tool firmly and exert care
when the drill bit begins to break through the
workpiece. There is a tremendous force exerted on
the tool/drill bit at the time of hole break through.
CAUTION:
A stuck drill bit can be removed
simply by setting the reversing switch to reverse
rotation in order to back out. However, the tool
may back out abruptly if you do not hold it firmly.
CAUTION:
Always secure workpieces in a
vise or similar hold-down device.
CAUTION:
If the tool is operated continuously
until the battery cartridge has discharged, allow
the tool to rest for 15 minutes before proceeding
with a fresh battery.
