Engine
WARNING: Before performing any
maintenance on the engine, disconnect the
spark plug wire and the battery to prevent
unintentional starting or sparking.
• Change engine oil after first five to eight hours of
use, then every 50 hours or every season,
whichever comes earlier. Change oil every 25
hours when operating the riding mower under
heavy load or in high temperatures.
• Poor engine performance and flooding usually
indicates that the air cleaner should be serviced.
Service pre-cleaner and the cartridge of the air
cleaner every 25 hours of use or once every
season, whichever comes earlier. Clean more
frequently under dusty conditions. Also replace air
cleaner parts ifthese are very dirty.
• The spark plug should be cleaned and the gap
reset every 100 hours of use or once a season,
whichever comes earlier.
Cleaning Engine
1. Promptly wipe off any fuel or oil spilled on the
machine with clean cloth.
2. Clean the underside of the blade housing after
each mowing. Do not let clippings or debris
accumulate around the blade which may cause rust
on the deck.
3. Using a brush or cloth, remove grass, chaff or
debris from the finger guard on the engine daily to
prevent overheating of the engine. Do not clean
with a forceful spray of water since water
contaminates the fuel system.
4. Keep the governor linkage, springs and controls
free of debris.
5. If engine muffler is equipped with spark arrester
screen, remove and clean the screen regularly.
Replace if damaged or plugged with debris.Clean
muffler area and remove any grass or other debris
before operating the unit.
NOTE: We recommend that the air cooling system be
serviced by an authorized service center every 100
hours of use. Also every 100-300 hours, have an
authorized service center remove combustion deposits
from the cylinder, piston and valves of the engine.
