hours and tighten or replace — as needed — before reusing the

Be sure to check the screws underneath the tiller hood that
secure the transmission cover and the Depth Regulator Lever to

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 separate engine manual
packed with your unit.
