Husqvarna YTH22V42 用户手册

Air screen must be kept free of dirt and chaff to prevent 

engine dam age from overheating.  Clean with a wire brush or 

compressed air to re move dirt and stubborn dried gum fibers.

Your engine will not run properly using a dirty air filter. Ser-

vice air cleaner more often under dusty conditions.

To ensure proper cooling, make sure the grass screen, 

cooling fins, and other external surfaces of the engine are 

kept clean at all times.
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. Ensure the cooling shrouds are reinstalled.
NOTE: Operating the engine with a blocked grass screen, 

dirty or plugged cooling fins, and/or cooling shrouds re moved 

will cause engine damage due to overheating.

Replace spark plugs at the beginning of each mowing 

season or after every 100 hours of operation, whichever 

occurs first.  Spark plug type and gap setting are shown in 

“PROD UCT SPECIFICATIONS” section of this manual.

• 

Keep finished surfaces and wheels free of all gasoline, 

oil, etc.

•  Protect painted surfaces with automotive type wax.
We do not recommend using a garden hose or pressure 

washer to clean your tractor unless the engine and trans-

mission are covered to keep water out. Water in engine or 

transmission will shorten the useful life of your tractor.  Use 

compressed air or a leaf blower to remove grass, leaves 

and trash from tractor and mower.

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

matter.

•  Clean debris from steering plate.  Debris can restrict 

clutch/brake pedal shaft movement, causing belt slip 

and loss of drive.

Inspect and replace corroded muffler and spark arrester (if 

equipped) as it could create a fire hazard and/or damage.

The fuel filter should be replaced once each season.  If fuel 

filter becomes clogged, ob struct ing fuel flow to car bu re tor, 

re place ment is re quired.
• 

With engine cool, remove filter and plug fuel line sec tions.

•  Place new fuel filter in position in fuel line with arrow 

pointing towards carburetor.

•  Be sure there are no fuel line leaks and clamps are 

properly positioned.

•  Immediately wipe up any spilled gasoline.

Replace the engine oil filter every season or every other oil 

change if the tractor is used more than 100 hours in one 

year.  See engine man u al.
