Safety class /II

• Due to our continuing program of research and
development, the specifications herein are subject to
change without notice.

• Specifications may differ from country to country.

Intended use

The tool is intended for impact drilling in brick, concrete
and stone as well as for drilling without impact in wood,
metal, ceramic and plastic.

Power supply

The tool should be connected only to a power supply of
the same voltage as indicated on the nameplate, and can
only be operated on single-phase AC supply. They are
double-insulated and can, therefore, also be used from
sockets without earth wire.

General Power Tool Safety Warnings

WARNING Read all safety warnings and all

instructions. Failure to follow the warnings and

instructions may result in electric shock, fire and/or
serious injury.

Save all warnings and instructions for future
reference.

HAMMER DRILL SAFETY WARNINGS

1. Wear ear protectors when impact drilling.

Exposure to noise can cause hearing loss.

2. Use auxiliary handle(s), if supplied with the tool.

Loss of control can cause personal injury.

3. Hold power tool by insulated gripping surfaces,

when performing an operation where the cutting
accessory may contact hidden wiring or its own
cord. Cutting accessory contacting a “live” wire may

make exposed metal parts of the power tool “live”
and could give the operator an electric shock.

4. Always be sure you have a firm footing.

Be sure no one is below when using the tool in
high locations.

5. Hold the tool firmly with both hands.

6. Keep hands away from rotating parts.

7. Do not leave the tool running. Operate the tool

only when hand-held.

8. Do not touch the bit or the workpiece
immediately after operation; they may be
extremely hot and could burn your skin.

9. Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation
and skin contact. Follow material supplier safety
data.

SAVE THESE INSTRUCTIONS.

WARNING:

DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to safety rules for the subject product. MISUSE or
failure to follow the safety rules stated in this
instruction manual may cause serious personal
injury.

ASSEMBLY

Installing side grip (auxiliary handle) (Fig. 1)

CAUTION:

• Always be sure that the tool is switched off and

unplugged before installing or removing the side grip.

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

CAUTION:

• Always be sure that the tool is switched off and
unplugged before installing or removing the bit.

For Model M8100 (Fig. 2)

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 it to the
original position.

For Model M8101 (Fig. 3)

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.

Depth gauge (Fig. 4)

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 grip base. 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 gear housing.

FUNCTIONAL DESCRIPTION

Switch action (Fig. 5)

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, push in the lock button
and then release the switch trigger. To stop the tool from
the locked position, pull the switch trigger fully, then
release it.

Reversing switch action (Fig. 6)

This tool has a reversing switch to change the direction
of rotation. Move the reversing switch lever to the D
position (A side) for clockwise rotation or to the E
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.

Selecting the action mode (Fig. 7)

This tool has an action mode change lever. For rotation
with hammering, slide the action mode change lever to
the right (g symbol). For rotation only, slide the action
mode change lever to the left (m symbol).

CAUTION:

• Always slide the action mode change lever all the way
to your desired mode position. If you operate the tool
with the lever positioned halfway between the mode
symbols, the tool may be damaged.

OPERATION (Fig. 8)

Always hold the tool only by the handle when performing
an operation. Do not touch the metal part.

Hammer drilling operation

CAUTION:

• There is 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 toll and potentially serve injury.

When drilling in concrete, granite, tile, etc., slide the
action mode change lever to the position of g symbol to
use “rotation with hammering” action. Be sure to use a
tungsten-carbide tipped bit. 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.
After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.

Drilling operation

When drilling in wood, metal or plastic materials, slide the
action mode change lever to the position of m symbol to
use “rotation only” action.

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. Use a cutting lubricant when
drilling metals. The exceptions 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 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.

• A stuck 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.

• Always secure small workpieces in a vise or similar
hold-down device.
