2. DESCRIPTION
2.1. Definition of Vibratory Tamper
Vibratory tamper is a compaction machine,
which executes fast repeating blows to the soil
which is compacted.
During compaction, distances between soil
particles get shorter, specific weight of the soil
increases and water contained in the soil is
pushed out.
Vibratory tampers are suitable for compaction
of backfills at digs, compaction of foundations,
etc.
2.2. Working Principles
The vibratory tamper is driven by a gasoline or
diesel, air cooled engine.
Torque from the engine is transmitted through a
centrifugal clutch to the gear mechanism of the
tamper, which converts rotation of the engine to
rectilinear movement of piston.
A strong spring located in the lower part of the
tamper transfers the force from the piston onto
the tamper foot.
2.3. Prior to Starting
1. The gear mechanism of the tamper is
lubricated by oil bath.
2. Prior to starting, check oil level in the sight
glass at the rear side of the tamper. If there
is no visible oil level, add oil. Use engine
oil, class SAE 10W-30, 15W-40, SE, SF or
better.
3. Add gasoline (either lead or lead-free) into
the fuel tank. Do not use mixture with oil for
4-stroke engines!
Check oil level in the engine. If necessary,
add engine oil, class SAE 10W-30, 15W-40
or better. Oil shortage can cause serious
damage to the engine. See also the engine
manual.
4. Check all bolts and nuts. Connections which
get loose from the vibrations may cause
serious problems. Therefore, re-tighten the
bolts properly.
5. Regularly clean the machine, especially
around the starter and the foot.

3. OPERATION
3.1. Starting
1. Turn the fuel tap down. Turn the ignition
switch to position „ON“.
2. At cold engine:
Close the choke. Set up the throttle lever
into position „OFF“.
At warm engine or high ambient
temperature:
Turn the choke lever into the middle
position or leave it fully open. Adjust the
throttle lever slightly above zero.
3. Hold the starting grip and pull a little, until
slight resistance is felt. From this point pull
vehemently. Do not release the grip then, but
return it into the basic position.
4. After the engine gets started, move the
choke lever slowly into the basic position.
Let the engine to warm up at idle speed for
3-5 minutes.
Check, whether there is no gasoline leaks
and whether there is no unusual noise.
5. If the engine does not get started after
several attempts, remove the sparkling plug
and check, whether it emits proper
sparkling. In case the plug is wet from fuel
or dirty, clean or replace it. Rotate the
engine several times before mounting the
plug back, to flush out excessive fuel.
3.2. Operation
1. Set up full throttle quickly to increase the
engine speed. The centrifugal clutch gets
engaged and the temper starts working.
Do not mode the lever slowly - that would
cause irregular operation of the tamper,
which may cause damage to the clutch,
springs and the foot.
2. When the rammer begins to operate, set the
frequency of strikes fine throttle adjustment.
Pech works most effectively when the
engine speed, which are shown on luck.
Unnecessary increase in speed is no longer
any increase in compaction force.
Conversely, resulting resonance reduces
compaction force and causing damage
3. At cold weather, the oil in the tamper foot is
mode dense and causes higher resistance of
the moving parts. This may cause slightly
irregular operation. In such a case it is
recommended to warm up the machine
before working by repeated increasing and
decreasing the engine speed.
4. The tamper foot is a highly durable
structure. However in case that rockfill
should be compacted, it is highly
recommended to put a layer of soil on the
top, in order to ensure even distribution of
compaction effort.

Vibratory tampers Operation manual
page 8 issued 05/2014
5. The tamper is designed to move forward
during operation. The forward speed can be
increased by pushing the handle down.
6.Work with the rammer quick stop moving the
throttle to "OFF"
3.3. Turning Off The Engine
1. After operation, let the engine to idle for 3-5
minutes to cool down. Then turn off the
engine by switching off the ignition.
2. Always remember to close the fuel tap.
3.4. Maintenance And Storage
