PAGE 22 — MVH508DZ PLATE COMPACTOR • OPERATION AND PARTS MANUAL — REV. #0 (04/04/14)
OPERATION
OPERATION
1. Once the engine has started, move the engine throttle
lever quickly to the operation position (Figure 16).
Figure 16. Throttle Lever (Operation Position)
2. With the throttle lever in the run position, the engine
speed should be around 2,300 RPM, therefore
engaging the centrifugal clutch.
3. Using the direction control lever, move the machine
backward or forward (Figure 17). When the direction
control lever is pushed forward, the machine moves
forward. When pulled backward, the machine moves
backward.

CAUTION
ALWAYS follow all safety rules in the safety
section of this manual before operating
compactor. Keep work area clear of debris
and other objects that could cause bodily
injury or damage to the compactor.

NOTICE
ALWAYS move the throttle lever quickly without
hesitation, because increasing the engine speed slowly
causes the clutch to slip.

the machine vibrates staying at the same location
5. Compactor traveling speed may drop on soils which
contain clay, however there may be cases where
traveling speed drops because the compaction plate
does not leave the ground surface easily due to the
composition of the soil. To rectify this problem do the
following:
• Check the bottom plate to see if clay or equivalent
material has been lodge in the plate mechanism. If so,
wash with water and remove.
• Remember the compactor does not work as efficiently
on clay or soils that have a high moisture content level.
• If the soil has a high moisture level, dry soil to
appropriate moisture content level or carry out
compaction twice.
STOPPING THE ENGINE
Normal Shutdown
1. Move the throttle lever to the idle position (Figure 18)
and run the engine for three minutes at low speed.
