REPLACEMENT / REGULATION OF THE BELT
!WARNING!
MAKE SURE THE MACHINE IS DISCONNECTED FROM POWER SUPPLY BY PULLING OUT THE PLUG FROM THE SOCKET.
On a new machine and after a belt replacement, make an inspection of the belt tightness :
10.After first 24 hrs of operation
11.After first 80 hrs of operation
12.Every 6 months or every 1000 operation hours - which ever come first. The belts are accessible from the rear of the machine.
If the belts are too tight the bearing seating are under stress and their life service will be shortened. If the belts are too loose they can be slipping on the pulley and can cause a noisy operation. In the case when it’s needed, tighten the belts.
MACHINES 16kg / 36lb
The testing force of belt tensioning is 200 N which can be measured by tension meter. Procedure for approximate belt tensioning with belt deflection 20mm / 0.78“ : apply a load of 5,5kg / 12lb to the middle of the belt. Change the belts if they are worn out or damaged.
!TO CHANGE THE BELTS:
NEVER USE A CROWBAR TO TAKE OFF THE BELTS OVER THE PULLEY GROOVES!
1.Dismantle the rear panel, fig. 5.2.D, (pos.1).
2.Take off the belts, (pos.2.) by pulling the belt and turning the drum pulley (pos.5).
3.Put a new belt (2) of identical type on pulleys (pos.5 and 8). The
4.The belt must be placed in the correct motor pulley trenches in such way the belt is running in the center of the drum pulley.
To tighten or loosen the belt tension :
1.Loosen the bolts (pos.4) for securing the motor position.
2.First unscrew the lower nut (pos.6) and then unscrew the upper nut (pos.7) for increasing the belt tension.
3.For decreasing the belt tension screw the lower and upper nut (pos.6 and 7) and lift the motor suspension. After this tighten all the bolts.
4.After the belt replacement, check the pulley alignment, the tightness of belts, bolts and nuts. Keep the belts and pulleys clean and free of oil, lubricants, water etc.
