WM63-SERIES MIXER • OPERATION AND PARTS MANUAL — REV. #0 (069/27/12) — PAGE 17
INSPECTION
V-BELT CHECK
Visually examine the V-belt (Figure 7) and determine if it
is full of tiny cracks, frayed, has pieces of rubber missing,
is peeling or otherwise damaged.
Also, examine the belt and determine if it is oil soaked or
"glazed " (hard shiny appearance on the sides of the belt).
Either of these two conditions can cause the belt to run hot,
which can weaken it and increase the danger of it breaking.
If the V-belt exhibits any of the above wear conditions
replace the V-belt immediately.

GREASE FITTINGS (DUMPING MECHANISM)

each end of the mixing drum. These grease fittings lubricate
the dumping mechanism. If the dumping handle is stiff or
hard to move, lubricate these grease fittings.
