and fragile materials without shattering them and control

the tool perfectly for precision chiselling.

- When we switch on the machine its gentle acceleration

allows smooth start up, avoiding bit veering from the

correct position. It also reduces the torque transmitted

to the gear, which is transmitted to the user when the

hammer is activated with the bit in an existing hole.

- Adjustable auxiliary handle C.

BEFORE USING THIS TOOL

Warning! Before carrying out any work, check, for instance,

using a metal detector that there are no electric wires or gas

or water pipes under the surfaces you wish to work on.

Make sure the mains voltage is correct: it must be the

same as that on the specification label. Machines with

230-V can also be connected to a 220-V mains supply.

To turn the machine on, press the ON/OFF switch I and

keep it pressed down.

When the ON/OFF switch is released, the machine stops.

1. Speed adjustments. Constant electronic performance

The control electronics allow continuous pre-setting of

the revolutions and impact frequency to adapt the ma-

chine to the type of material to be worked on. Adjust-

ment is made using the speed adjustment switch H,

which has 6 positions to regulate the speed.

The higher the number, the greater the speed and

impact energy. The range of settings from “1” (low

power) to “6” (full power) makes the tool very flexible

and adaptable to different applications.

The constant speed control maintains the pre-set num-

ber of revolutions and impact frequency.

2. Mode selection switch (see Fig. 2)

Warning!: This switch E should only be activated with

the machine off.

Press the release button D on the mode selection switch

E, and turn the latter to the required setting:

Hammer only (blocked): for hollowing out

grooves, (light) scraping, chiselling and wrecking.

Hammer drilling (simultaneous rotation and percus-

sion): for drilling in concrete and masonry work.

Hammer only (blocked): for hollowing out

grooves, (light) scraping, chiselling and wrecking.

3.- Fitting and removing tools (SDS-max



)

The dustproof hood A prevents the entry of dust during

operation. When fitting tools, take care not to scratch the

dustproof hood A.

Fitting the tool (see Fig.4.)

1. Clean and slightly lubricate the tool before fitting.

2. Pull back the bit holder ring B and fit the clean tool in

the tool-holder, turning until in place.

3. Release the bit holder ring.

4. Pull the tool to ensure it is blocked.

To remove the tool (see Fig.4).

Push back the bit holder ring B on the toolholder, and

remove the bit.

4. Auxiliary handle

WARNING: For safety reasons, the hammer should only

be used with the auxiliary handle C securely fitted.

Ensure that it is firmly fitted before use.

Fitting in forward position.

1. Unscrew the auxiliary handle C.

2. Insert the clamp until K in the clamp collar J.

3. Screw the handle back on firmly C.

5. Safety clutch

Should the drill tool seize up or become jammed, the

drilling rotation stops.

Due to the resulting forces, hold the machine firmly in

both hands, taking care to maintain it in a stable

position.

6. Built-in dust guard

The toolholder has a dustproof hood A. This prevents

dust entering the toolholder during work. The dust guard

should be checked when the brushes are being changed

by the service centre, and replaced if necessary.

OPERATING MODES

Hammer drill mode

For drilling in concrete, cement, etc.,

1. Press the release button E.

2. Set the selector switch D to .

Use bits with tungsten carbide tips.

Place the bit where you wish to make the hole, then

press the trigger. Do not force the tool. You will obtain

better results by applying only light pressure. Hold the

tool in place so that it does not move from the hole.

Should the hole become blocked with shavings or other

particles, do not apply greater pressure. Rather use the

tool on the minimum setting, and then partially remove

the bit from the hole. If you repeat this operation a few

times the hole will come clean.

WARNING: When the bit begins to penetrate concrete

or comes up against the reinforcement rods in the con-

crete, the tool may react dangerously. Make sure you

keep your balance by distributing your weight evenly and

keeping your feet in a safe position whilst holding the

tool firmly in both hands to avoid dangerous reactions.

Hammer only

For chipping, descaling or wrecking,

1. Press the release button D.

2. Set the mode selection switch E to .

Use a chipping tool, cold chisel, descaler, etc.

NOISE AND VIBRATION

The machine’s noise and vibration levels, measured in

compliance with EN60745-1, usually reach:

Acoustic pressure = 96 dB(A)

Sound-power level = 109 dB(A)

Use ear protection!

Vibration acceleration = 14 m/s

ACCESSORIES

Accessories and their corresponding order number can

be found in our catalogues.

MAINTENANCE AND CARE

WARNINGAlways unplug the machine before carrying

out work on it.

- When you notice a decrease in hammer output, take

the machine to an Official Service Centre.

- Tool inspection: Using a blunt cutting tool leads to

less efficient work and could damage the motor,

therefore cutting tools should be sharpened or re-
