slowly. Do not overfill. For approximate capacity see
"PRODUCT SPECIFICATIONS" section of this man u al.
• Use gauge on oil fill cap/dipstick for checking level.
Be sure dipstick cap is tightened securely for accurate
reading. Keep oil at "FULL " line on dipstick. Tighten
cap onto the tube securely when finished.
ENGINE OIL FILTER
Replace the engine oil filter every season or every other oil
change if the tractor is used more than 100 hours in one year.
AIR FILTER
Your engine will not run properly using a dirty air filter. Ser-
vice air cleaner more often under dusty conditions.
CLEAN AIR SCREEN
The air screen is over the air intake blower located on top
of engine. The 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.
