WARNING
Do not move the gear
selection handle
with the wheels or
tines engaged. Make
certain the unit is
stopped completely
before changing the
gear selection. A
partial engagement
may be necessary
when engaging tines.
Do not push down
on the handles so
that the wheels are
lifted off the ground
while using the tine
drive, or the tiller
could move backward
and cause personal
injury.
Never attempt to
make any adjust-
ments while the
engine is running,
except where speci-
fied in operator’s
manual.
Off-Season Storage
If the tiller will not be used for a period longer than 30 days, the
following steps should be taken to prepare the tiller for storage.
• Clean the exterior of engine and the entire tiller
thoroughly. Lubricate the tiller as described in the
lubrication instructions.
• We do not recommend the use of pressure washers
to clean your unit. They may cause damage to
electric components, spindles, pulleys, bearings or
the engine. The use of pressure washers will result
in shortened life and reduce serviceability.
• Refer to the engine manual for correct engine
storage instructions.
• Wipe tines with oiled rag to prevent rust.
• Store tiller in a clean, dry area. Do not store next to
corrosive materials, such as fertilizer.
NOTE: When storing any type of power equipment in an
unventilated or metal storage shed, care should be taken
to rustproof the equipment. Using a light oil or silicone, coat
the equipment and especially any springs, bearings, and
cables.
