MAINTENANCE AND
DEPOSIT FOR A LONG TIME
Spraying units.
Clean out any residual spray mixture
or dust in the chemical tank and
all other parts after operation with
clean water and dry it.
Clean the dust gate and chemical
tank inside and outside after
dusting.
Loosen the chemical tank lid while
the machine free.
Let the machine run at a low speed
2-3 minutes after cleaning.
FUEL SYSTEM
MAINTENANCE
Water or dirt in fuel is one of the
main causes of the engine trouble,
clean the fuel system regularly.
Residual fuel remaining in the fuel
tank and carburetor for long time
will gum and clog the fuel system,
thus cause the engine not to
working properly.
So all of the fuel should be
discharged if the machine isn't used
after one week.
AIR FILTER AND PLUG
Clean the filter after every day
operation. Dirt adhering to sponge
reduces the engine power.
Dry filter before reinstalling.
Clean stains or carbon off the spark
plug and adjust spark gap to 0.6 ~
0.7mm.
The plug model of this machine is
4106J.
Do not use other models, if it is
