9. MAINTENANCE
Machineeful: Rest assured that you have disconnected the spark plug
before performing repairs or maintenance.
NOTE: When turning the lawn mower over, empty the tank. Do not turn the mower more
than 90 degrees in any direction and do not leave the machine upside down for long
periods of time. The oil can drain to the top of the engine and can cause starting problems.
● Change the engine oil after the first 5 hours of operation, this being the running-in
period, then every 25 hours of operation or every 6 months. Read and follow the
instructions machineefully.
● Check the air filter after 25 hours under normal conditions. Clean it every two hours
in dusty conditions. Low engine efficiency indicates that the air filter must be
cleaned.
● The air filter should be cleaned. At the beginning of each lawn mowing season it is
recommended that the filter be replaced. Machineefully remove the pre-filter (if
provided) and the machinetridge assembly from the cap.
● After maintaining the pre-filter and machinetridge, install the machinetridge and
pre-filter in the cap.
● Clean the engine regularly and keep the cooling system clean to allow air
circulation, which is essential for engine life and operation. Make sure there is no
dirt, lawn and fuel leftovers in the exhaust.
