MAINTENANCE WORK AND REPLACEMENT OF WEARING PARTS

6.7  CHANGING THE RUBBER BEARINGS OF THE 

SANDING DISC GEAR

Only use original LÄGLER rubber bearings (order no. in 

Section 11, 

Spare parts

).

1

 

Switch off the machine. 

Disconnect power supply before commencing any work on 
the machine; this will prevent inadvertent motor action!

3

 

Release the clamping lever of the handle, press handle for-

ward and pull the clamping lever back into its prior position 

(Fig. 51).

4

 

While holding on to the handle, carefully tilt the machine back-

wards into a horizontal position. Make sure that the machine 

gets to rest safely on the guide tube and the two protective 

cushions (Fig. 52). 

Make sure the machine is in a safe posi-

tion!

5

 

Remove the sanding discs or brushes. To do this, grasp the 

gear edges with your fingers and pull the gear out of the rub-

ber jig (Fig. 53).

6

 

Use a screwdriver to prize the rubber bearings out of the 

sanding disc gear (Fig. 57).

7

 

Insert the new rubber bearings. Make sure you have the cor-

rect insertion position! The larger diameter of the bearings 

must be inserted in the hole first (Fig. 57)!

8

 

Tilt the machine forward into working position and adjust 

handle. Connect power again.

The machine is now ready to use.

Replacing the rubber bearings. Make sure of the 
correct insertion position!

6

ATTENTION!
Make sure the gear is in place correctly. It must slide in place 
with a perceptible click. Always use three gears of the same 
type!
