Crown CT18183 BMC [24/164] Design features of the power tool

English

Mounting / replacement of accessories (see g. 3)

Borers SDS PLUS are able, due to the de-

signed features of the chuck SDS PLUS,

to travel freely to some extent� This causes

radial run-out at idle running that will be

automatically centred during the drilling� It doesn't

make any impact on the precision of bore drilling�

• Before installing the borer (chisel), clean it and lubri-

cate the shank with a thin layer of oil�

• When mounting borer (chisel):

• insert (slightly twisting) the borer (chisel) into the

chuck 1 (SDS PLUS) against stop (see g. 3.1);

• test the borer (chisel) xing by trying to remove it

from chuck 1 (SDS PLUS)�

• When removing borer (chisel):

• move xing bush 3 back and hold it in this position

(see g. 3.2);

• extract the borer (chisel) from the chuck 1

(SDS PLUS);

• release xing bush 3�

Gloves are to be used when removing the

borer (chisel) from chuck 1 (SDS PLUS),

as the borer (chisel) may be dangerously

hot after long drilling.

Replacing the dust protection casing (see g. 4)

Dust protection casing 2 prevents

the dust from entering the SDS PLUS

chuck. Never use your power tool with

a damaged dust protection casing 2 - if

damaged, it must be immediately replaced. You can

either do it on your own, or contact the CROWN

service center.

• Move xing bush 3 back and hold it in that position

(see g. 4).

• Pull dust protection casing 2, and remove it�

• Install a new dust protection casing 2�

• Release xing bush 3�

Adapter for chuck SDS PLUS

• SDS PLUS adapter 14 and screw 13 enable using

gear rim chuck 15�

• Never use SDS PLUS adapter 14 in the impact drill-

ing or chiselling operation modes�

• Drills that don't belong to the SDS PLUS system are

not allowed for the percussion drilling�

Mounting / dismounting of the gear rim chuck (see

g. 5-6)

• Screw the gear rim chuck 15 onto the SDS PLUS

adapter 14 and lock it in with the screw 13 (see

fig� 5)�

• Install the SDS PLUS adapter 14 into the

chuck 1 (SDS PLUS), repeating the same steps as

when mounting the borer (chisel) see g. 6.

• When dismantling, repeat the steps described

above in the reverse order�

Attention: keep in mind that in the pro-

cess of mounting / dismounting of the

gear rim chuck 15 the screw 13 has a left-

hand thread.

Mounting / replacement of accessories

With long-term use the drill bit may be-

come very warm; use gloves to remove

it.

Gear rim chuck (see g. 7)

• Release the cams grip with drill chuck key 16, then

rotate the quill of gear rim chuck 15 counter-clockwise

with your hand (see g. 7) until the cams move apart

at the distance allowing an accessory to be mounted /

replaced�

• Mount / replace an accessory�

• Rotate the quill of gear rim chuck 15 clockwise with

your hand in order to lock the accessory mounted� Do

not allow the accessory to become distorted�

• Tighten the cams of gear rim chuck 15 with drill

chuck key 16 applying a similar torque to each of the

three openings on the side surface of the chuck�

Initial operation of the power tools

• Always use the correct supply voltage the power

supply voltage must match the information quoted on

the power tool identication plate.

• The power tool is supplied properly lubricated and

ready for use�

• A new power tool needs some time for its parts to

run in before a full load operation� The run-in period

duration is about 5 hours of operation�

• The gear lubrications require a short time to get

warm� Depending on the ambient temperature this

period of time can alter within the range of approxi-

mately 15 s (at ambient temperature of 32°С) up to 2

minutes (at ambient temperature of 0°С).

Switching the power tool on / off

Short-term switching on / off

To switch on, press and hold on / off switch 11, to

switch off - release it�

Long-term switching on / off

Switching on:

Push on / off switch 11 and lock it in the position with

lock-on button 12�

Switching off:

Push and release on / off switch 11�
