MVC-90L PLATE COMPACTOR — OPERATION
Operation
1. Once the engine has started, move the engine throttle lever
quickly to the FAST position. With the throttle lever in the fast
position, the engine speed should be around 2,300 RPM,
which engages the centrifugal clutch.
2. Firmly gasp the compactor's handle bar with both hands as
the compactor begins moving forward.
3. Slowly walk behind the compactor and be on the lookout for
any large objects or foreign matter that might cause damage
to the compactor or bodily injury.
Make sure to follow all safety rules referenced in the safety
section of this manual before operating compactor. Keep work
area clear of debris and other objects that could cause damage
to the compactor or bodily injury.
Operating the Compactor on High Moisture Content Soil
Compactor traveling speed may drop on soils which contain clay,
or other types of soil. Soil with high moisture content can cause
the compaction plate to "stick" to the ground (not lifting up off the
ground very fast or high).
To rectify this problem, consider the following:
z
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.
z
Remember the compactor does not work as efficiently on
clay or soils that have a high moisture content level.
z
If the soil has a high moisture level, dry soil to appropriate
moisture content level or carry out compaction twice.
Always move the throttle lever
quickly without hesitation.
Increasing the engine speed slowly
causes the clutch to slip and can
damage your clutch.
CAUTION - General Operation Safety
NOTE
Using the Compactor Sprinkler System
The MVC-90L is equipped with a watering system that can be
used to wet the ground during compaction to keep dust levels
down.
To operate the watering system, turn the water cock handle to
open the valve (Figure 18) and start the water flow. With the
compactor at full speed and the water cock fully open, the water
system will provide approximately 20 minutes of sprinkling.
Figure 18. Water System
Whenever the compactor's vibra-
tion becomes weak or lost during
normal operation regardless of op-
eration hours, check the V-belt and
clutch immediately.
