OPERATION
Description
Danger
The SRP 2240/3860 is a reversible vibrating plate operat-
ing on the basis of the twin-shaft vibration system prin-
ciple. The engine drives the exciter on the baseplate via
a centrifugal clutch and a V-belt. The exciter produces the
vibration required for compaction as a result of the built-in
imbalance.
The machine is guided at the tow-bar grip. It is operated
with the operating controls on the tow-bar.
The SRP 2240/3860 is suitable for all compaction work in
the fields of civil engineering and road construction. It can
be used to compact all ground materials such as sand,
gravel, slag, crushed stone, asphalt and composite sett
paving.
Take great care on downslopes. The machine
could slip down due to loose material or if the
surface is slippery.
Do not use the machine on hard concrete, set
asphaltic surfaces, highly frozen or unstable
surfaces.

1 Control lever
The control lever serves for adjustment of the unbalances
in the exciter and in turn for coninuous regulation.
I Forward
0 Point compacting
II Reverse
The control lever remains automatically in position only
when set to the maximum forward travel setting (a). In any
other position, the control lever moves in the direction of
maximum forward travel when released.
If the control lever is operated too quickly several times, the
shift lever will block in reverse travel. In this case:
• Release lever in forward travel position up to maximum
forward travel position
• Blocking is cleared within a few seconds and perfect
shifting is possible.
The control lever can be operated only with the engine
running. The lever blocks if operated when the machine is
stationary. Blocking is immediately cleared when the engine
is restarted.
2 Engine speed control lever
STOP Engine stop (SRP 3860 only)
MIN Idle (detent position)
MAX Full load.
The motor speed can be adjusted steplessly with the con-
trol lever. At minimum motor speed (min), the drive to the
exciter is disconnected at the centrifugal clutch and the mo-
tor idles. The centrifugal clutch engages when the control
lever is moved approximately ¼ of its adjustment travel.
