Replace Engine Oil and Filter
NOTE: Change engine oil and filter after first 50 hours on a
new machine and every 500 hours thereafter.
1. Position a larger container under drain valve beside left
wall of fuel tank. Loosen drain valve and allow all engine oil
to drain out. Tighten drain valve.
NOTE: Oil warming is good when replacing oil. If
machine is cold, operate the engine to bring the
coolant temperature up to about 40°C (104°F).
When the needle of the coolant temperature
gauge reaches the middle of the "WHITE
ZONE," the temperature is about 40°C (104°F).
NOTE: Dispose of drained fluids according to local
regulations.
2. Replace engine oil filter (Figure 74). Engine oil filter is a
spin-on type. Remove and discard filter.
3. Install new filter. Apply a small amount of oil around filter
gasket. Screw filter on head until gasket contacts head by
hand, turn filter 3/4 - 1 turn more with filter wrench.
NOTE: See “Fluid Capacities” on page 4-16, for
capacity and “Table of Recommended
Lubricants” on page 4-14, of this manual for
recommended oil for the operating conditions.
4. Fill engine with correct oil through oil fill port.
5. Start engine and check engine oil pressure warning light.
6. Shut down engine. Look for signs of leaks at filter. Recheck
oil level.
Use clean 15W-40 oil to coat the gasket surface of the filter.
Fill the filter with clean 15W-40 oil.
CAUTION!
Never attempt to change oil or filter on a hot engine.
Hot oil could splash and cause burns. Allow engine to
cool down before changing oil or filter.
