MAINTENANCE WORK AND REPLACEMENT OF WEARING PARTS
10 Mount the new V-belts and tension the drive belt using
the tensioning bolt at the motor (Fig. 63, 1).
The slack on the V-belt should be approx. 1 cm (3/8") if
compressed with normal effort (Fig. 63, 2).
ATTENTION!
Orient the belt tensioner to the fan pulley! Move the belt
tensioner accordingly (Fig. 64)! A wrong orientation from
belt tensioner to fan pulley (Fig. 65) increase the wearing
of fan axle, pulleys and V-belt extensive! Then these parts
must be replaced significant more often!
11 Turn the belt tensioner counterclockwise to tension the fan
V-belt (Fig. 66, 1). Keep the belt tensioner in position and
tighten the clamping screw at the belt tensioner carefully
at the same time (Fig. 66, 2).
The slack on the V-belt should be approx. 1 cm (3/8") if
compressed with normal effort (Fig. 67).
12 Tighten the two motor nuts (Fig. 33).
13 Mount the belt guard.
ATTENTION!
• Never tension the V-belts excessively! This can cause
damage to the V-belts and ball bearings!
• Check the tension of the V-belts after a while! Reten-
sion the V-belts if necessary!
Fig. 66 By turning the tensioner, tighten the smaller
V-belt (1) and carefully tighten the clamping
screw (2).

Fig. 63 Tension the drive belt using the tensioning bolt
at the motor (1).
The slack on the V-belt should be approx. 1 cm
(3/8") if compressed with normal effort (2).
Similar to figure.
Fig. 64 Orient the belt tensioner to the fan pulley.
Fig. 65 Avoid position A and B of the belt tensioner!
Otherwise the wearing of the pulleys and the
V-belt increase extensive!
