6. MAINTENANCE AND TROUBLESHOOTING
If possible, please stop the engine, pull off the spark plug socket, and allow
the engine to cool down prior to performing any maintenance work. If it is
necessary to keep the motor running for performing certain maintenance
work, please ensure sufficient ventilation because the exhaust gases are
toxic.
Regular maintenance and thorough care will reduce the risk of possible operational malfunction
and contribute to extend the life cycle of the unit. The technical design of engines is very complex,
and they contain a huge number of moving parts which are subject to high mechanical, thermal
and chemical influences from the side of the environment and the combustion process. The use of
proper, high - quality and fresh operating fluids - fuel and motor oil - will prevent both damage to the
engine and downtimes.
Abrasive matters contained in the liquid being discharged - such as sand - accelerate wear and
tear and reduce the performance of the pump. When discharging liquids containing such matters,
the installation of a prefilter is recommended. This useful accessory it will efficiently filter sand and
similar particles out of the liquids, thus minimize wear and tear and extend the lifetime of the pump.
6.1. Oil change and oil level check
When using models with auto - lubrication, please check the oil level prior to
each use.
Every 100 operating hours or at least once a year and after the first 20 operating hours an oil
change must be performed. On models with auto - lubrication, an oil change should be carried out
at least once per year. During this period of time, the quality of the motor oil will clearly drop even if
the device is used only infrequently. To carry out such an oil change, please drain the old oil and fill
in new oil through the filling opening into the oil reservoir.
