Reversing switch action
For Model HP2040, HP2041 (Fig. 2)

rotation. Move the reversing switch lever to the position
(A side) for clockwise rotation or the position (B side)
for counterclockwise rotation.
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.
Speed change (Fig. 3)
Two speed ranges can be preselected with the speed
change lever.
To change the speed, turn the speed change lever to the
position 1 for low speed or the position 2 for high speed. If
the speed change lever does not turn easily, turn the
chuck slightly in either direction and turn the lever again.
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, the tool may be damaged.
• Do not use the speed change lever while the tool is
running. The tool may be damaged.
Selecting the action mode (Fig. 4)
This tool has an action mode changing button.
For rotation with hammering, depress the button from the
side with symbol fully.
For rotation only, depress the button from the side with
symbol fully.
CAUTION:
• Always depress the action mode changing button all
the way to your desired mode position. If you operate
the tool with the button positioned halfway between the
mode symbols, the tool may be damaged.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing side grip (auxiliary handle)
(Fig. 5)
Always use the side grip to ensure operating safety. Install
the side grip so that the teeth on the grip fit in between the
protrusions on the tool barrel.
Then tighten the grip by turning clockwise at the desired
position. It may be swung 360° so as to be secured at any
position.
Installing or removing drill bit
For Model HP2041 (Fig. 6)
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 clockwise
to tighten the chuck.
To remove the bit, hold the ring and turn the sleeve
counterclockwise.
For Model HP2040, HP2042 (Fig. 7)
To install the bit, place it in the chuck as far as it will go.
Tighten the chuck by hand. Place the chuck key in each of
the three holes and tighten clockwise. Be sure to tighten
all three chuck holes evenly.
To remove the bit, turn the chuck key counterclockwise in
just one hole, then loosen the chuck by hand.
After using the chuck key, be sure to return to the original
position.
Depth gauge (Fig. 8)
The depth gauge is convenient for drilling holes of uniform
depth. Loosen the side grip and insert the depth gauge
into the hole in the side grip. Adjust the depth gauge to the
desired depth and tighten the side grip.
NOTE:
• The depth gauge cannot be used at the position where
the depth gauge strikes against the tool body.
