Changing the Engine Oil
Service Interval: After the first 5 hours
Every 50 hours
Yearly or before storage
Note: Max. fill: 0.59 l (20 oz), type: SAE 30 detergent oil
with an API service classification of SF, SG, SH, SJ, SL, or
higher.
1. Move the machine to a level surface.
2. Ensure that the fuel tank contains little or no fuel so
that fuel does not leak out when you tip the machine
onto its side.
3. Run the engine a few minutes before changing the oil
to warm it.
Note: Warm oil flows better and carries more
contaminants.
4. Disconnect the wire from the spark plug; refer to
Preparing for Maintenance (page 14).
5. Set an oil-drain pan beside the machine on the side of
the dipstick.
6. Remove the dipstick from the oil-fill tube (Figure 37).

7. Tip the machine onto its side, with the oil-fill tube
down, to drain the used oil out through the oil-fill tube
into the oil-drain pan (Figure 38).
8. After draining the used oil, return the machine to the
operating position.
9. Pour about 3/4 of the crankcase capacity of oil into
the oil-fill tube.
Note: Max. fill: 0.59 l (20 oz), type: SAE 30 detergent
oil with an API service classification of SF, SG, SH,
SJ, SL, or higher.
10. Wipe off the dipstick end with a clean cloth.
11. Insert the dipstick into the oil-fill tube and screw it in
until it stops.
12. Remove the dipstick and read the oil level; refer to
Figure 37.
•
If the oil level is too low, add a small amount of oil
slowly to the oil-fill tube, and then repeat steps 10
through 12 until the oil level is correct as shown in
Figure 37.
•
If the oil level is too high, drain the excess oil until
you obtain the correct oil level on the dipstick.
Important: If the oil level in the crankcase is
too low or too high and you run the engine,
you may damage the engine.
13. Install the dipstick securely by hand.
