MAINTENANCE

Two minute rule

The machine may be tipped forward to facilitate
access for cleaning or service, but 

no longer than

2 minutes

.

If the machine is held in this position for too long,
the engine can be damaged by gasoline draining
into the crankcase. Should this happen, perform
an extra oil change on the engine. Remove the
spark plug and turn the engine over a few
revolutions with the starter handle before starting
the engine again.

Cleaning and washing

Regular cleaning and washing will increase the
machine’s lifespan. Make it a habit to clean the
machine directly after use, before the dirt sticks.

Check before rinsing that the fuel tank lid is properly
in place to avoid getting water in the tank.

Use caution when using high-pressure spray
because warning decals, instruction signs and the
engine can be damaged. 

Do not exceed 1000 PSI

water pressure when cleaning

.

Lubricate the machine after cleaning. This is
particularly important if the machine is to be stored.
