Check the effects of vibration
Compacting work in the vicinity of buildings can lead to structural damage. For this reason
you must always check the possible effects of vibrations on surrounding buildings in the
run-up to work.
You must take the following points into special consideration when evaluating the effects
of vibration:
• Vibration behavior, sensitivity and resonance frequency of surrounding buildings
• Distance of the buildings from the vibration site (= worksite).
• Condition of the soil.
You may need to carry out measurements to determine the vibration speed.
You must also comply with the relevant guidelines and regulations,
particularly DIN 4150-3.
The foundation must also have sufficient load-bearing capacity to withs
compaction energy. In case of doubt involve a soil mechanics specialist in the
evaluation. Tomahawk Power is not liable for any s
tructural damage.

Description
2.3 Description of function
.1
2.3
The vibration required for compaction is produced by the exciter (5) which is firmly joined
to the lower mass (8). This exciter (5) is designed as a central vibrator with aligned
vibrations. Such a principle permits the direction of vibration to be changed by turning the
eccentric weights. In this way an infinitely variable transition between vibration in forward
motion, at standstill and in reverse motion is possible. This process is hydraulically
controlled with the operating control handle (1) on the handle bar (2).

throttle control lever (3). The upper (7) and lower (8) masses are connected to each
other by 4 vibration-damping rubber metal shock mounts (9). This damping system
prevents the very high frequencies from being transmitted to the upper mass (7). As a
result the function ability of the drive engine (11) is retained in spite of the high
compaction performance. The drive engine (11) works on the diesel principle; it is
started electrically by a pinion starter (10), draws in the combustion air through an air
filter, dry and is air-colled.
2.3.7 To facilitate the starting procedure (at very low temperatures, with hand start) the drive
engine (11) has an automatic decompression mechanism. It ensures that compression is
very low during the cranking operation but steadily increases after a few revolutions
when it then switches over to full compression.

3.2 Recommendations on compaction
3.2.1 Ground conditions
The maximum compaction depth depends on several factors relating to the ground
condition, such as moisture, grain distribution etc,
it is therefore not possible to specify exact values.
Recommendation: In each case determine the maximum compaction depth with
compaction tests and soil samples

4.3 Forward and reverse motion
The engine speed can be infinitely varied on the throttle control lever.
The direction of travel is determinate with the shift lever (6).
Depending on the position of the shift lever (6), the vibration plate compacts in forward
direction, at standstill or in reverse direction.
The forward and reverse speeds can be varied by selecting intermediate positions of the
shift lever (6) or the machine can be employed for particularly intensive compaction at
standstill.
4.4 Switching off
Never switch off the engine with the automatic decompression (2) as this inevitably results
in damage to the valve drive and decompression mechanism.
Move the throttle control lever (8) to the stop.
4.5 Compaction without extension plates

4.6 Additional notes on starting at very low temperatures!
Never use starting sprays or similar - they are forbidden because they are dangerous.
Only use original Wacker crank.
If cranking, is too slow, the engine can start running in the opposite direction of
rotation.
In this case the air is drawn in through the exhaust and the exhaust gases excape
through the air filter. Risk of fire! Switch off engine and start it again.
Free the engine by turning it approximately 10 to 20 times with the
decompression lever in a central position. Then the engine is
decompressed, but not ready to start. This intermediate position is used to
turn the engine "free" when at very low temperatures. The turning
resistance becomes appreciably lower owing to the change in viscosity of
the oil film. At the same time you will hear that the nozzle of the fuel
injection system is injecting cleanly (rattling).
At very low temperatures (below -5
o
C), use the starting oil dosing device.
Note: Do not use more than 2 doses as otherwise there is a risk
of crank back-swing.
