Maintenance And Repair - Scheppach HP3000S Translation From The Original Instruction Manual

■ STARTING ENGINE
1. Move the fuel valve lever to the ON po-
sition To start a cold engine, move the
choke to the CLOSE position
2. To restart a warm engine, leave the choke
■ RECOIL STARTER
Pull the starter grip lightly until you feel re-
sistance, then pull briskly, return the start-
er grip gently. If the choke lever has been
moved to the CLOSE position to start the
■ FORWARD AND REVERSE MOTION, FIG. 3
The direction of travel is determined with
the operating control shifter. Depending on
the position of the control shifter, the plate
compacts in forward direction or in reverse
direction.
1. To make the compactor move in the for-
ward direction, push the shift stick for-
ward.
2. To make the compactor move in the re-
verse direction, pull the shift stick back-
wards.
m 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 ex-
cessive kickback is noticed.

When traveling backwards, the operator
has to guide the vibration plate laterally
■ 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, re-
■ IDLE SPEED
Set throttle control lever to its SLOW posi-
tion to reduce stress on the engine when
compacting is not being performed.

WARNING
Prior to carrying out one of the following adjustment steps, switch the machine off!
■ MAINTENANCE
Maintaining your compactor will insure long
life to the machine and its components.
Preventive Maintenance Turn off engine.
Engine must be cool. Keep the engine's
throttle lever in its SLOW position, and re-
move 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

engine, gradually move it to the OPEN posi-
tion as the engine warms up. After engine
warms up, pull throttle lever to accelerate
engine speed and place the shift stick at the
by its guide handle so that you will not be
squeezed between the handle and a pos-
sible 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 un-
der 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 rap-
idly. 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.
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 extreme-
ly wet, allow it to dry somewhat before com-
pacting.
If soil is so dry as to create dust clouds while
turn the engine throttle lever to idle posi-
tion.
2. Allow engine to cool down for one or two
minutes before stopping.
3. Turn the engine switch to ''OFF" position.
Lowering the engine speed to idle the en-
gine will help extend the life of the engine,
as well as conserve fuel and reduce the

machine oil to lubricate all moving parts.
Clean the bottom of the compactor base as
soon as it begins to pick up soil being com-
pacted. The unit can not do a good job if the
bottom surface is not smooth and clean. Re-
place spark plug wire.
