Every 100 hours of operation (more often under extremely dusty, dirty conditions), remove the blower housing and other

cooling shrouds. Clean the cooling fins and external surfaces as necessary. Make sure the cooling shrouds are reinstalled.

NOTE: Operating the engine with a blocked grass screen, dirty or plugged cooling fins, and/or cooling shrouds removed will cause engine damage due to overheating.

CLEANING

•Clean engine, battery, seat, finish, etc. of all foreign matter.

•Keep finished surfaces and wheels free of all gasoline, oil, etc.

•Protect painted surfaces with automo- tive type wax.

We do not recommend using a garden hose or pressure washer to clean your tractor unless the engine and transmis- sion are covered to keep water out. Water in engine or transmission will shorten

the useful life of your tractor. Use com- pressed air or a leaf blower to remove

grass, leaves and trash from tractor and mower.
