  • Page 29: Driving Mechanism

    Every time you use a grease gun especially for greasing bearings and seals, do it slowly - not faster than 5 strokes in 1 minute. The grease gun can create a high pressure which would cause the seal deformation and consequent leakage. Never operate the grease gun faster even if the grease contain air gaps. Overlubrication can cause the same damage as an insufficient lubrication.

    BELT REPLACEMENT NEVER USE A CROWBAR TO TAKE OFF THE BELTS OVER THE PULLEY GROOVES. Loosen the bolts of tightening pulley on the drum rear wall and the adjusting screw for taking the belts off. TWO - MOTOR VERSION: Belts between motor for washing and motor for extracting are to be removed after loosing the bolts that fasten the motor for extracting and after loosing the tightening bolts.
