3. The direction control lever allows the machine to be moved either backward or forward (Figure 21). When the direction control lever is pushed forward, the machine moves forward. When pulled backward, the machine moves backward.
NOTICE
Your unit may be equipped with direction control levers on both the right and left side of the handle. Earlier models only have one control lever located on the right side of the handle.
Figure 21. Direction Control Lever
4. When the direction control lever is the neutral position, the machine vibrates staying at the same location.
NOTICE
NEVER
stop the engine suddenly while working at high speeds.
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 lodged 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.

CAUTION
ALWAYS
allow the engine to cool before servicing.
NEVER
attempt any maintenance work on a hot engine.
MAINTENANCE
General Cleanliness
Clean the compactor daily. Remove all dust and debris buildup (mud, clay etc.). If the compactor is steam-cleaned, ensure that lubrication is accomplished
AFTER
steam cleaning.
NOTICE
Inspection and other services should always be carried out on hard and level ground with the engine shutdown.
NOTICE
The inspection intervals listed in the maintenance tables are for operation under normal conditions. Adjust your inspection intervals based on the number hours plate compactor is in use, and particular working conditions.
CAUTION
ALWAYS
disconnect the spark plug wire from the spark plug and secure away from the engine before performing maintenance or adjustments on the machine.
