Zenoah HC510DV Saw User Manual


 
Clogging of air filter reduces engine
performances. Inside of an engine will quickly
wear by dusts if an air cleaner cover is not
correctly fitted or if a filter is missed, deformed,
or damaged.
Avoid dusts to penetrate into the engine when
removing the air filter. Cover an air inlet with a
cloth after removing the filter.
To keep the engine performance, change the air
filter at every 20 hours of operation.
SPARK PLUG
Do not touch the spark plug by bare hands
immediately after stopping the engine. There is
a danger of burn for its high temperature.
About every 25 hours of operation, remove the
spark plug and clean contaminant on electrodes
with a wire brush, etc.
Applicable gap between the electrodes is
0.6~0.7mm.
Use specified spark plug for exchange.
Specified Spark Plug:
NGK BPM8Y
Electrodes of the spark plug are contaminated by
over sucking of fuel or by poor quality oil. This may
cause the engine start difficult.
FUEL FILTER
About every 25 hours of operation, remove a fuel
filter from the fuel tank and remove adhered debris.
In case the filter is clogged, exchange with a new
one.
Care should be taken not to bend a fuel pipe when
setting the filter back into the tank.
