Idler Pulley Rod

stretched, you may need to adjust the idler pulley rod. This can
be checked easily.
With the engine off and the clutch control bail disengaged, shift
the gear selection handle to each forward mode. If the indicator
bracket touches the idler pulley rod with the clutch control bail
disengaged, then an adjustment is necessary.
Disconnect and ground the spark plug wire against the
engine.
Remove the belt cover as described under Belt
Replacement in the Service section.
Remove the hairpin clip and spring washer from the idler
pulley rod. See Fig. 6-1.
Move the idler pulley rod to the lower hole in the idler
bracket.
Replace the spring washer and hairpin clip.
Check the clearance of the idler pulley rod to the indicator
bracket by shifting to each forward mode.

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 the engine and the entire tiller
thoroughly. Lubricate the tiller as described in the
Lubrication instructions.
Using a pressure washer to clean your tiller is not
recommended. The washer may cause damage to the
electric components, spindles, pulleys, bearings or the
engine. Using a pressure washers will result in shortened
life and reduce serviceability.
Refer to the Engine Operator’s Manual for the correct
engine storage instructions.
Wipe the tines with an oiled rag to prevent rust.
Store the 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 area 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.
