Compaction
Do not operate plate on concrete or on extremely hard, dry, compacted surfaces. The plate
will jump rather than vibrate and could damage both plate and engine.
The number of passes required to reach a desired compaction level will depend on the type and moisture
content of soil. Maximum soil compaction has been reached when excessive kickback is noticed.
When moving backwards, the operator has to guide the vibration plate laterally by its guide handle so that you
will not be squeezed between the handle and a possible obstacle. Special care is required when working on
uneven ground or when compacting coarse material. Make sure of a firm stand when operating the machine
under such conditions.
In operation, guide the machine, but let the compactor do the work. Bearing down on the handle is
unnecessary and causes shock absorber wear.
On level surface, the compactor moves forward rapidly. On uneven surfaces or inclines, light forward pressure
on handle may be required to assist the compactor in moving forward.
When using plate on paving stones, attach a pad to the bottom of the plate to prevent chipping or grinding
surface of the stones. A special urethane pad designed for this purpose is available as an optional accessory.
While a certain amount of moisture in the soil is necessary, excessive moisture may cause soil particles to
stick together and prevent good compaction. If soil is extremely wet, allow it to dry somewhat before
compacting.
If soil is so dry as to create dust clouds while operating plate, some moisture should be added to the ground
material to improve compacting. This will also reduce service to the air filter.
The following points are to be observed when compacting on sloped surfaces (slopes, embankments etc.):
1.
Only approach gradients from the bottom (a gradient which can be easily overcome upwards can also
be compacted downwards without any risk).
2.
The operator must never stand in the direction of descent.
3.
The max. gradient of 20° must not be exceeded.
If this gradient were exceeded, this would result in a failure of the engine lubrication system
(splash lubrication) and thus inevitably lead to a breakdown of important engine
components.
Stopping Engine
To stop the engine in an emergency, simply turn the engine switch to the OFF position. Under normal
conditions, use the following procedure.
1.
To stop the compactor from travelling, return the engine throttle lever to idle position.
2.
Allow engine to cool down for one or two minutes before stopping.
3.
Turn the engine switch to ‘‘OFF” position.
4.
Turn off the fuel valve where applicable.
