7.4 The V-belts
The V-belt drive is designed for the installed driving power. To force a
higher output through an excessive high tension of the V-belt will
break the belt, damage bearings and cause losses of the total
efficiency. Too low belt tension will cause slipping with the result of a
very high temperature of the V-belt a premature destruction of it.
Temperatures over 70° for a longer period will decrease the working
life and the efficiency of the V-belt. The grooves of the V-belt pulleys
must be free of rust, fat and dirt and must not show any damages.
The use of belt wax or similar substances in order to increase the
friction coefficient is not necessary and it damages the V-belt. Soiling
due to oil, grease or chemicals have to be avoided.
In order to get perfect power transmission the V-belt drive has to be
checked regularly.
The V-belt drive is located behind the Compressor panel.
The V-belt tension device is located behind the Left lower panel.
