When using demolition or chipping bits

such as bull points, chisels, spades,

gouges, etc. the "Hammer Only" mode

must be selected.

▶ "Vario-Lock"

The Vario-Lock position is intended for

use with chipping bits such as bull

points, spades, gouges, etc. Choose a

position which is best suited for your

operation.

Turn the mode selector dial, to the

"vario-lock" setting. Next, rotate the

locking sleeve, along with the accessory,

to the desired position. Then turn the

mode selector dial to the "hammer only"

setting and slightly turn the locking

sleeve to have it automatically lock into

a definite position (Fig. 11).

▶ Slip Clutch

The tool has a internal pre-set slip

clutch. The output spindle will stop

rotating if the accessory binds and

overloads the tool.

▶ Kickback Control

The rapid shut-off feature enables better

control and improves user's comfort. The

power tool automatically shuts off in case

of sudden and unexpected rotation of the

power tool around the drilling axis (for

example jamming of the drill bit in

reinforcing steel or wedging application

tool).To restart the machine, release the

On/Off switch and then actuate again.

Kickack Control can activate only when

the power tool is running at maximum

operating speed and can rotate freely

around the drill bit axis.

Following a few simple tips will reduce

wear on the tool and the chance of

injury to the operator.

NOTE: The high efficiency available

from the rotary hammers can only be

obtained if sharp and undamaged

accessories are used. The "cost" to

maintain

sharp

and

accessories is more than offset by the

"time saved" in operating the tool with

sharp accessories.

You will extend the life of your bits and

do neater work if you always put the bit

in contact with the workpiece BEFORE

pulling the trigger. During operation,

hold the drill firmly and exert moderate,

steady pressure. Too much pressure at

low speed will stall the hammer. Too

little pressure will keep the bit from

cutting and cause excess friction by

sliding over the surface. This can be

damaging to the drill and bit.

Shanks of all drill bits should be wiped

clean prior to using and immediately

after removing.

Recall these instructions for safe

operation:

Some materials require slow

drilling speeds; whereas, others

require higher speed to produce

the best results.

All work must be supported or

secured before drilling and steady,

even pressure applied in line with

the drill bit.

As the drill bit cuts through the

opposite side, reduce the pressure

and continue running the drill as

the bit is withdrawn.

Materials such as glass, porcelain,

ceramics, tiles, plastics, etc., should be

drilled at low speeds with specially

designed drill bits and lubricants.

If backing block is not used, ease up on

the pressure just before the bit breaks

through the wood to avoid splintering.

Complete the hole from the opposite

side immediately after the point breaks
