WARNING: Shut off the engine before
performing any maintenance. To
prevent accidental start-up, disconnect
the spark plug boot.
IMPORTANT: If engine must be tipped to transport
equipment or to inspect or remove grass, keep spark
plug side of engine up. Transporting or tipping engine
spark plug down may cause smoking, hard starting,
spark plug fouling, or oil saturation of air cleaner.
Periodic inspection and adjustment of the engine is
essential if high level performance is to be maintained.
Regular maintenance will also ensure a long service life.
The required service intervals and the kind of mainte-
nance to be performed are described in the table below.
Follow the hourly or calendar intervals, whichever occur
first. More frequent service is required when operating in
adverse conditions.
Maintenance Schedule
† Service more frequently when used in dusty areas.
†† If operating under heavy load or high ambient temperature.

• Be sure correct oil level is maintained. Check every
5 hours or daily before starting engine. See oil

up) and allowing oil to drain into a suitable container.
See Figure 10-1.

equipment to drain oil, drain fuel from
tank by running engine until fuel tank is
empty.
2. Reinstall the drain plug (if removed), and tighten it
securely.
3. Refill with the recommended oil (see page 16) and
check the oil level. See Figure 10-1.
