Servicing The Air Cleaner - Toro 74406 Operator's Manual

pour only enough oil into the fill hole to raise
the level to, but not over, the Full mark on the
dipstick.
Important: Do not overfill the crankcase
with oil because the engine may be
damaged.
Changing and Draining the Oil
1. Start the engine and let it run until warm. This
warms the oil so it drains better.
2. Park the machine so that the drain side is
slightly lower than the opposite side to ensure
that the oil drains completely.
3. Disengage the blade control switch and move
the control levers to the neutral locked position
and apply the parking brake.
4. Stop the engine, remove the key, and wait for
all moving parts to stop before leaving the
operating position.
5. Slide the drain hose over the oil drain valve
(Figure 25).
6. Place a pan below the oil drain hose. Use either
a flat screw driver, 3/8 inch (10 mm) wrench
to open valve (Figure 25).
7. Rotate valve end counterclockwise to open
valve (Figure 25).
8. When oil has drained completely, rotate valve
end clockwise to close the valve (Figure 25).
9. Remove the drain hose.
Note: Dispose of the used oil at a certified
recycling center.

operating conditions are extremely dusty or sandy.
1. Drain the oil from the engine; refer to
Changing and Draining the Oil.
2. Remove the old filter (Figure 26).
3. Apply a thin coat of new oil to the rubber
gasket on the replacement filter.
