soil compaction has been reached when
excessive kickback is noticed.
When traveling 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 ope-
rating 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 for-
ward rapidly. On uneven surfaces or inclines,
light forward pressure on handle may be requi-
red to assist the compactor in moving forward.
■ 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 traveling, return
■ IDLE SPEED
Set throttle control lever to its SLOW position
to reduce stress on the engine when compac-
m
WARNING
Prior to carrying out one of the following adjustment steps, switch the machine off!
■ MAINTENANCE
Maintaining your compactor will insure long life
tothe machine and its components. Preventive
Maintenance Turn off engine. Engine must
be cool. Keep the engine's throttle lever in
its SLOW position, and remove spark plug
wire from spark plug and secure. Inspect the
general condition of the plate compactor.
Check for loose screws, misalignment or
binding of moving parts, cracked or broken
parts, and any other condition that may affect
its safe operation. Remove all debris from the
plate compactor with a soft brush, vacuum, or
compressed air. Then use a premium quality
lightweight machine oil to lubricate all moving
parts. Clean the bottom of the compactor
base as soon as it begins to pick up soil being
compacted. The unit can not do a good job if
the bottom surface is not smooth and clean.
Replace spark plug wire.
m Never use a "pressure washer" to clean
your plate compactor. Water can penet-
rate tight areas of the unit and cause da-
mage to spindles, pulleys, bearings, or
the engine. The use of pressure washers
will result in shortened life and reduce
serviceability.
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 purpo-
se 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
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.

Maintenance and repair

Checking and replacing V-belt (Fig.
4).
To ensure optimum power transmission from
the engine to the eccentric shaft, the V-belt
must be in good condition.
1. Turn off engine.
2. Engine must be cool.
3. Remove the belt guard (I) to access
the V-belt. Check the condition of the
V-belt. If any V-belt is cracked, frayed, or
glazed, it should be replaced as soon as
convenient.
4. Loosen the 4 lock nuts (M12) at the
rubber buffers
Replacing V-belt
Slip the old V-belt off of the wheel pulley and
install the new V-belt in its place.
Position the V-belt over the engine pulley and
tension pulley.
Drive belt (a) tensioning when the belt more
than 10-15 mm yields (press with thumb)
Turn all 4 eccentrics (X) upwards to tension
the belt and downwards to solve it
5. Replace the belt guard.

compacting on sloped surfaces (slopes, em-
bankments):
1. Only approach gradients from the bottom
(a gradient which can be easily overcome
upwards can also be compacted down-
wards without any risk).
2. The operator must never stand in the
direction of descent.
3. The max. gradient of 20° must not be
exceeded
m 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.
m Do not move choke control to CLOSE
to stop engine. Backfire or engine
damage may occur.
the life of the engine, as well as conserve fuel
and reduce the noise level of the machine
m When removing or installing the drive
belt, be careful not to get your fingers
caught between the belt and pulley.
Exciter oil change (Fig. 5)
The exciter housing is pre-serviced using
Automatic Transmission Fluid SAE 10W 30 or
its equivalent. Change fluid after 200 hours of
operation.
1. Let exciter cool before changing exciter oil.
2. Tilt the plate toward a drain pan to aid in the
removal of all used oil and particles.
3. Remove oil drain plug to drain oil from the
exciter assembly. Examine oil for metal chip
as a precaution to future problems.
4. After oil has been completely drained from
the machine, reinstall drain plug.
5. Return plate housing to the upright position.
6. Add the exciter housing with exciter oil
through filler plug opening.
7. Apply sealant to filler plug and reinstall it.
m Do not overfill – overfilling can result
in excessive temperatures in the exciter.
