Switch action (Fig. 1)
CAUTION:
• Before plugging in 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 switch trigger. Tool speed
is increased by increasing pressure on the switch trigger.
Release the switch trigger to stop.
For continuous operation, pull the switch trigger and then
push in the lock button.
To stop the tool from the locked position, pull the switch
trigger fully, then release it.
Reversing switch action (Fig. 2)
This tool has a reversing switch to change the direction of
rotation. Move the reversing switch lever to the
(A side) for clockwise rotation or the
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 lever.
For rotation with hammering, turn the lever to the position
of symbol.
For rotation only, turn the lever to the position of
symbol.
CAUTION:
• Always turn the action mode changing lever fully to
your desired mode position. If you operate the tool with
the lever 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 HP2033 (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 HP2032 (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.
position
position (B side) 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.
OPERATION
Hammer drilling operation
• There is a tremendous and sudden twisting force
exerted on the tool/bit at the time of hole break-
through, when the hole becomes clogged with chips
and particles, or when striking reinforcing rods
embedded in the concrete. Always use the side grip
(auxiliary handle) and firmly hold the tool by both side
grip and switch handle during operations. Failure to do
so may result in the loss of control of the tool and
potentially severe injury.
When drilling in concrete, granite, tile, etc., turn the
action mode changing lever to the position of
use "rotation with hammering" action.
Be sure to use a tungsten-carbide tipped bit.
Position the bit at the desired location for the hole, then
pull the switch trigger. Do not force the tool. Light
pressure gives best results. Keep the tool in position and
prevent it from slipping away from the hole.
Do not apply more pressure when the hole becomes
clogged with chips or particles. Instead, run the tool at an
idle, then remove the bit partially from the hole. By
repeating this several times, the hole will be cleaned out
and normal drilling may be resumed.
Blow-out bulb (optional accessory) (Fig. 9)
After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.
Drilling operation
• 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 bit, decrease the tool
performance and shorten the service life of the tool.
• There is a tremendous force exerted on the tool/bit at
the time of hole break through. Hold the tool firmly and
exert care when the bit begins to break through the
workpiece.
