Maintenance
WARNING
When removing the
cutting blade or belt,
protect your hands
with a pair of heavy
gloves or use a heavy
rag to hold the blade.
An unbalanced blade
will cause excessive
vibration when rotat-
ing at high speeds. It
may cause damage
to mower, and could
break causing per-
sonal injury.
We do not recommend
the use of pressure
washers or garden
hose to clean your
unit. These may cause
damage to electrical
components, spindles,
pulleys, bearings, or
the engine. The use
of water will result in
shortened life and
reduce serviceability.
