Pivot
Chain
WARNING: Disconnect spark plug wire and ground it against the engine before performing any repairs or maintenance.
Trouble Shooting
Refer to the trouble shooting chart for more information.
Engine
Refer to the separate engine manual for all engine maintenance instructions.
Maintain engine oil as instructed in the separate engine manual packed with your unit. Read and follow instructions carefully.
Service air cleaner every 25 hours under normal conditions. Clean every few hours under extremely dusty conditions. Poor engine performance and flooding usually indicates that the air cleaner should be serviced. To service the air cleaner, refer to the separate engine manual packed with your unit.
IMPORTANT: Never run your engine without air cleaner completely assembled.
The spark plug should be cleaned and the gap reset once a season. Spark plug replacement is recommended at the start of each tilling season; check engine manual for correct plug type and gap specifications.
Clean the engine regularly with a cloth or brush.
Keep the cooling system (blower housing area) clean to permit proper air circulation which is essential to engine performance and life. Be certain to remove all dirt and combustible debris from muffler area.
Cleaning The Tine Area
Clean the underside of the tine shield after each use. The dirt washes off the tines easier if washed off immediately instead of after it dries.
We do not recommend the use of pressure washers to clean your unit. It 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.
Belt Removal And Replacement
Your tiller has been engineered with belts made of special material (Kevlar Tensile). They should not be replaced with an
Forward Drive Belt - Part No. 754-0428
Reverse Drive Belt (390 Only) - Part No. 754-0429
