Ɣ

Different values of torque are applied to various types of screws and materials.

Ɣ

The higher is the number corresponding to a given position, the higher is the torque (

fig. B

).

Ɣ

Set the torque control ring (

2

) to a specified amount of torque.

Ɣ

The work should be started with a lower value of torque.

Ɣ

The torque should be increased gradually until satisfying results are obtained.

Ɣ

Higher settings should be used to tighten screws.

Ɣ

Settings marked with a drill bit symbol must be used for drilling. The highest value of torque is obtained 
in this setting.

Ɣ

The ability to select proper torque settings is gained along with with practice.

The setting of the torque control ring to the drilling position deactivates the overload clutch.

ROTATION DIRECTIONS - LEFT AND RIGHT

The direction of spindle rotations is selected by means of the rotation direction switch (

5

) (

fig. A

).

Left rotations

 - set the rotation direction switch (

5

) in the extreme left position.

Right rotations

 - set the rotation direction switch (

5

) in the extreme right position.

* It is reserved that in some cases the position of the rotation direction switch in relation to rotations may be different than 
described. Refer to graphic signs located on the rotation direction switch or on the tool housing.

The direction of rotations can not be changed, when the tool spindle rotates.

CHANGING SPEED

The speed change switch (

3

) (

fig. C

) is used to increase the rotational speed.

Speed I

: lower range of rotations, high torque

Speed II

: higher range of rotations, lower torque

Depending on performed works, the speed change switch should be set in a proper position. If the switch 
is hard to move, the spindle must be rotated slightly.

The speed change switch can not be operated, when the tool works. This could damage the tool.

Long-lasting drilling with low torque of the spindle may overheat the motor. Periodical breaks 
in operation must be taken or allow the tool to operate with maximum speed without load for 
approximately 3 minutes.

OPERATION AND MAINTENANCE

Before any operations related to installation, adjustment, repairs or maintenance are commenced, 
the plug of the power cord should be disconnected from the socket.

MAINTENANCE AND STORAGE

Ɣ

It is recommended to clean the tool after each use.

Ɣ

Do not use water or other fluids for cleaning.

Ɣ

The tool should be cleaned with a brush or blown with compressed air of low pressure. Do not use any 
cleaning agents or solvents, since they may damage plastic parts.

Ɣ

Venting slots in the motor housing should be cleaned on a regular basis not to overload the tool.

Ɣ

When the commutator sparks excessively, have the condition of motor carbon brushes checked by a 
qualified person.

Ɣ

The tool should always be stored in a dry place and out of reach of children.

REPLACEMENT OF THE QUICK COUPLING CHUCK

The quick coupling chuck is tightened to the spindle thread of the electric drill driver and additionally 

protected with the screw.

Ɣ

Open the jaws of the quick coupling chuck (

1

) and screw in the clamping screw (left thread) (

fig. D

).

Ɣ

Fasten the hexagonal key in the quick coupling chuck and slightly tap the other end of the hexagon 
key.

Ɣ

Loosen the quick coupling chuck.

The quick coupling chuck is installed in the reverse order to the removal.
