▪ Hammer mode (Fig.5) - chiselling grooves

and demolishing in concrete, masonry, etc.

▪ Adjusting the chisel (Fig.6) - to avoid opera-

tor’s fatigue, insert and x the chisel in the

necessary position.

INSERTING AND fASTENING SDS

PLUS BITS

Clean and grease the shank of the accessory,

before placing it into the socket! (Fig.7)

Pull backward the locking sleeve 3 of the SDS

plus socket (4) (Fig.8a). Insert the bit until stop.

Ensure that the socket grooves correspond to

the bit shank channels, and then release the

sleeve to x the bit. (Fig.8b)

To remove the bit, pull the sleeve 3 backward,

and then take the bit out. (Fig.9)

WARNING: Never use bits with diam-

eter exceeding the indicated to avoid over-

loading the power tool.

INSERTING AND fASTENING DRILL

BITS WITH STRAIGHT SHANK INTO

THE CHUCK

Place the mode selection switch 11 in position

«Drilling» (Fig.3). Insert the chuck 12 into the

SDS plus socket 4 as described above. In this

conguration the rotary hammer can operate in

drilling mode.

for keyed chuck

By turning the collar of chuck 12 clockwise or

anti-clockwise the jaws move to a position en-

suring inserting the drill bit shank. Rotate the

collar of the chuck clockwise to tighten the drill

bit shank. Fix the drill bit nally into the chuck

by means of the special chuck key, tightening

equally in all three bores.

for keyless chuck

Grip the rear collar of the chuck and rotate its

front collar until the chuck is opened sufciently

for the tool to be inserted, and then tighten the

front collar. An audible “click” indicates that the

chuck has automatically locked.

ADJUSTING THE CHISEL POSITION

Insert the chisel into the socket as it is described

in section “Inserting SDS-Plus bits”.

Turn the operating mode switch 11 in position

«Adjusting the chisel» (Fig.6).

Rotate the tool by hand to the desired position

(Fig.10).

Turn the operating mode switch 5 to position

«Hammer» (Fig.5), and then turn the tool slightly

by hand leftwise and rightwise until it is locked.

Longer operation life of the rotary hammer and

higher efciency can be achieved only with well

sharpened tools for demoliting and chiselling.

SCREWING / UNSCREWING BOLTS,

SCREWS AND NUTS

Following the above-described procedure, tight-

en the corresponding accessory into chuck 12.

Set mode selector switch 11 to position «Drill-

ing» (Fig.3). Select the necessary rotation direc-

tion by lever 7. These operations must be per-

formed only at low speed.

WARNING: In case of driving long

bolts and screws there is a danger of slipping

the rotary hammer!

AUXILIARY HANDLE

Tighten the auxiliary handle 1 on the journal 2 of

the rotary hammer. In the interests of safety, the

auxiliary handle 1 should always be used. The

depth gauge 5 can be used for xing the depth

of the drilled bores.

TORQUE LIMITATION

The safety clutch limits the torque. Upon actu-

ating the safety clutch stops the spindle rota-

tion and the tool (drill bit) ceases to rotate. In

this case switch the machine off immediately to

avoid premature wear.

RECOMENDATIONS fOR OPERATION

Apply moderate pressure during drilling in con-

crete (approximately 80-100 N). Higher pres-

sure will not increase drilling efciency, but it

will result in decreasing the operation life of the

machine.

Take the drill bit out of the opening from time to

time to remove dust.

Watch out for the stage of blunting of the bit and

change it if considerable decrease of efciency

is observed.

Do not operate the machine in «Hammer drill-

ing» and «Hammer» mode with the lever 7 in

rightmost position.

Depending on the processed material it is possi-

ble that the impact energy may decrease during

operation in «Hammer» mode (chiselling and

demolishing and in «Hammer drilling» mode. To

restore the maximum impact energy it is neces-

sary to reduce the revolutions by decreasing the

pressure on the switch trigger 9 until the advent

of stable impact.

Before drilling large-diameter holes in metal,

rst drill a small pilot hole.

The optimum capacity for drilling in concrete

with twist drill bits is shown in the table with tech-

nical specications.

The rotary hammer is suitable for light-duty chis-

elling. Higher durability and efciency can be

achieved only when using sharp chisels.

VII - Maintenance

GENERAL INSPECTION

Regularly inspect all fasteners and ensure they

are properly tightened. Should any of the screws

be loose, retighten it immediately to avoid haz-

ards.

If the replacement of the supply cord is neces-

sary, this has to be done by the manufacturer or

his agent in order to avoid a safety hazard.

CLEANING

For safe operation always keep the machine

and its ventilation slots clean.

Regularly check to see if any dust or foreign

matter has entered the ventilation slots and the

grills around the switches. Use a soft brush and/

or air jet to remove any accumulated dust. Wear

safety glasses to protect your eyes whilst clean-

ing.

Exterior plastic parts may be cleaned with a

damp cloth and mild detergent if necessary.
