V-BELT INSPECTION
Visually examine the V-belt (Figure 8) 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 referenced wear conditions
replace the V-belt immediately
Figure 8. Drive Belt Inspection
V-BELT TENSION
The V-belt tension is proper if the V-belt bends 10 to 15 mm

VIBRATOR OIL CHECK
1. Place the plate compactor horizontally on a flat surface.
Make sure the compactor is level when checking the
oil in the vibrator assembly.
2. Check vibrator oil level by removing the oil plug (vibrator
oil gauge) as shown in Figure 10. Clean the oil gauge
and re-thread back in. Remove the oil gauge again and
confirm oil level does not exceed the cross hash of the
oil plug.
DO NOT OVERFILL!

3. The vibrator holds approximately 11.8 oz. (350 cc).
IMPORTANT, if oil is required, replace using only SAE
10W-30 motor oil.
