MAINTENANCE
Checking Engine Oil
1. Check engine oil level daily before starting the engine.
2. When checking or adding oil, place the machine so
the engine is level.
3. Pull the engine oil dipstick from its holder (Figure 37,
Item 10).
4. Determine if engine oil is low. Oil should be between
the upper and lower limit (add oil) lines.
5. If oil is below the “Add Engine Oil” line, add oil up to
the upper limit on the dipstick. Allow enough time for
any oil to make its way to the oil pan before rechecking.
Changing Engine Oil And Filter
1. Change the engine oil after the first 5 hours of use,
then change every 6 months or 125 hours.
2. Remove the oil filler cap (Figure 37, Item 13), and fill
engine crankcase with recommended type oil as listed
in Table 2. Fill to the upper limit of dipstick.
3. Crankcase capacity with filter replacement is 8 quarts,
(7.57 liters). Refer to Table 9 for recommended viscosity
grade for temperature range.
CAUTION — Do Not Overfill
DO NOT overfill the oil pan with engine oil. Always keep
the engine oil level at the upper limit lines on the dipstick
due to the tilting of the engine during operation.
