Servicing The Engine Oil - Toro 44538 Operator's Manual

Servicing the Engine Oil

Note: Change the oil more frequently when the
operating conditions are extremely dusty or sandy.
Oil Type: Detergent oil (API service SG, SH, SJ or
higher)
Crankcase Capacity: w/filter, 67 oz. (2 l)
Viscosity: See the table below.
Checking the Engine Oil Level
Service Interval: Before each use or daily
Note: The best time to check the engine oil is when the
engine is cool before it has been started for the day. If it
has already been run, allow the oil to drain back down
to the sump for at least 10 minutes before checking. If
the oil level is at or below the 'add' mark on the dipstick,
add oil to bring the oil level to the 'full' mark. DO NOT
OVERFILL. If the oil level is between the 'full' and
'add' marks, no oil addition is required.
1. Park the machine on a level surface.
2. Turn the ignition key to off, and remove the key.
3. Clean around the oil dipstick (Figure 18) so that dirt
cannot fall into the filler hole and damage the engine.

4. Unscrew the oil dipstick and wipe the end clean
(Figure 18).
5. Slide the oil dipstick fully into the filler tube, but do
not thread onto tube (Figure 18).
6. Pull the dipstick out and look at the metal end. If the
oil level is low, slowly pour only enough oil into the
filler tube to raise the level to the Full mark.
Important: Do not overfill the crankcase with
oil and run the engine. Engine damage can
result.
Changing the Oil
Service Interval: Every 100 hours
1. Start the engine and let it run five minutes. 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 the oil drains
completely.
3. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
4. Place a pan below the drain. Rotate oil drain valve to
allow oil to drain (Figure 19).
Note: A hose may be inserted onto the drain valve
to direct the oil flow.
5. When oil has drained completely, close the drain
valve.
Note: Dispose of the used oil at a recycling center.
