Maintenance
Engine
Refer to the Engine Maintenance section for all engine
maintenance.
TirePressure
Check the air pressure in both tires. The air pressure should
be between 15-20 PSI. Keep both tires equally inflated to help
prevent machine from pulling to one side.
Check for loose or missing hardware after every 10 operating
hours and tighten or replace -- as needed -- before reusing the
tiller
Be sure to check the screws underneath the tiller hood that
secure the transmission cover and the Depth Regulator Lever to
the transmission.
Air Filter
The air cleaner filters dirt and dust out of the air before it enters
the carburetor. Operating the engine with a dirty and/or clogged
air filter can cause poor performance and damage to the engine.
Never operate the engine without the air cleaner installed.
Inspect and service the air cleaner more often if operating in
very dusty or dirty conditions. Refer to the Engine Maintenance
section for air cleaner service intervals and instructions.
