Husqvarna YTH2042TD 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.

Inspect and replace corroded muffler and spark arrester 

(if equipped) as it could create a fire hazard and/or dam-

age.

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.

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.

• 

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.

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.

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

vice air cleaner more often under dusty conditions.
