GENERAL
It is important that the machine is maintained correctly to
ensure proper function. It should be kept clean so that any
leakage, loose bolts and loose connections can be discov-
ered in time.
Make a habit of inspecting the machine every day before
starting up by checking all round it to detect any sign of
leakage or other faults.
SPARE A THOUGHT FOR THE ENVIRONMENT!
Do not let oil, fuel and other environmentally hazard-
ous substances contaminate the environment.
Always dispose of used filters, drained oil and any
remaining fuel properly.
This manual contains instructions for periodic attention
which should normally be carried out by the operator.
There are additional instructions relating to the
engine, for which the manufacturer’s instructions
are detailed in the engine manual.

SAFETY INSTRUCTIONS (FOR ALL LIGHT PRODUCTS)
Working with the hydraulic system
Regular maintenance of the hydraulic system is
important. Minor damage or a split hose or cou-
pling can have devastating consequences. Bear
in mind that the hydraulic hoses are made of
rubber and can deteriorate with age, which can
result in splitting. In all cases of uncertainty with
regard to durability or wear, replace the hoses
with new original hoses from Dynapac.
Working with battery
The battery contains poisonous and corrosive
sulphuric acid. Wear protective glasses and
avoid getting acid on your skin, clothes or on the
machines. If you get sulphuric acid on yourself,
rinse the skin with water. If you get acid in your
eyes, rinse them with water for at least 15 min-
utes and seek immediate medical treatment. The
gas that is emitted by the battery is explosive.
When fitting or replacing a battery, always take
care so that you do not short- circuit the battery
poles.
Repair
Never use a machine that is damaged. Qualified
repair work requires trained personnel, please
contact your nearest authorized workshop.
Extinguishing fires
If there is a fire in or on the machine, it is best
to use an ABE-class fire extinguisher.
However, a BE-class CO2 extinguisher is
also suitable.

strike and can be severely damaged. The
ramming shoe may especially be damaged
severely. Make certain that the rammer is
steared only by using the hand grip. It should
only be pushed. The rammer must not be
pressed into the materials being compacted.
Excessive pressure to the operation handle
will lead to the unsatisfactory compaction due
to the fact that the jumping action is hindered.
If the machine falls over while working, switch
off the engine before raising it.
Stopping the engine

Put the throttle in the stop mode. Fuel supply to the
engine is cut off in this mode, tank ventilation is
