The number of passes required to reach a de
-
sired compaction level will depend on the type
and moisture content of soil. Maximum soil
compaction has been reached when exces
-
sive 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 oper
-
ating 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
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 acces
-
sory. While a certain amount of moisture in
the soil is necessary, excessive moisture may
cause soil particles to stick together and pre
-
vent 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, 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.
■ 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
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.
m
Do not move choke control to CLOSE
to stop engine. Backfire or engine
damage may occur.
■
IDLE SPEED
Set throttle control lever to its SLOW position
to reduce stress on the engine when compact
-
ing is not being performed. Lowering the en
-
gine speed to idle the engine will help extend
the life of the engine, as well as conserve fuel
and reduce the noise level of the machine

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. Preven
-
tive 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 gen
-
eral 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 opera
-
tion. Remove all debris from the plate compac
-
tor 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 pen
-
etrate tight areas of the unit and cause
damage to spindles, pulleys, bearings,
or the engine. The use of pressure
washers will result in shortened life and
reduce serviceability.
Checking and replacing V-belt (Fig.

.
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 conveni
-

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.
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.
Changing the motor oil..
After 20 operating hours, the oil must be
changed for the first time, then every 100
operating hours.
1.
Remove the flexible hose D and poor the oil
into a suitable bin.
2.
Open the filling cap (measuring stick) and
let the oil drain.
3.
Reconnect the flexible hose.
4.
Fill the oil (1,1l) in, check with the measuring
stick, and close.
5.
Pull starter slowly for 5 times, so that the oil
spreads (without ignition)
Recommended motor oil SAE 10W-40
Dispose of waste oil according to your
country’s regulations. It is not allowed to
drain waste oil onto the ground or mix it with
other waste material. Important hint in case of
sending the plates to a service station: Due to
security reasons please see to it that the vibra
-
tory plates are sent back free of oil and gas!
To remove the oil proceed as follows:
1.
Remove the flexible hose D and poor the oil
into a suitable bin.
2.
Open the filling cap (measuring stick) and
let the oil drain.
3.
Reconnect the flexible hose.
