Adjusting of safety switch – freestanding machines
The safety switch is an important component which must - if
correctly adjusted - stop the machine when excessive
movement and shaking occur due to an unbalance caused
by improper distribution of linen
in the washing drum, or when the amount of laundry exceeds
the machine capacity.
o
Setting the safety switch without laundry inserted in drum:
7-8-11-14 kg / 15-18-25-30 lb: X = 5 - 15 mm / 0.2 - 0.59”
18-24-28 kg / 40-55-65 lb: X= 0 - 10 mm / 0 - 0.39“
The X dimension represents the distance between the lower
edge of the lug and the stick of safety switch, see figure 33.
WARNING!
DO NOT USE THE MACHINE IF THIS FUNCTION DOESN’T WORK PROPERLY!
THIS FUNCTIONAL TEST CAN ONLY BE EXECUTED BY A QUALIFIED TECHNICIAN WITH PROPER
AUTHORIZATION.
Belt replacement and adjusting tension
WARNING!
MAKE SURE THE MACHINE IS DISCONNECTED FROM POWER SUPPLY BY USE AND SECURE
THE DISCONNECTING DEVICE.
WARNING!
TO CHANGE THE BELTS: NEVER USE A CROWBAR, SCREW DRIVER OR ALIKE TO TAKE OFF THE
BELTS OVER THE PULLEY!
On a new machine and after a belt replacement, make an inspection of the belt tightness:
o
After first 24 hrs of operation
o
After first 80 hrs of operation
o
Every 6 months or every 1000 operation hours - which ever comes first.
The belts are accessible from the rear of the machine. If the belts are too tight or too loose, the durability
will be shortened. If too loose they can be slipping on the pulley and can cause a noisy operation and
generate excessive wear with fast breaking as consequence. In such cases correcting the belts tension is
necessary, see the recommended values below.
