Servicing the Air Cleaner

Service Interval: Every 50 hours
Clean the air filter. Replace the air filter every 200 hours or
once a month.
1. Make sure wire is off spark plug.
2. Remove cover over the air cleaner and clean cover
thoroughly (Figure 14).

3. If foam element is dirty, remove it from paper element
(Figure 14). Clean thoroughly as follows:
• Wash foam element in a solution of liquid soap and warm
water. Squeeze to remove dirt, but do not twist because
the foam may tear.
• Dry by wrapping in a clean rag. Squeeze rag and foam
element to dry, but do not twist because the foam may
tear.
• Saturate element with clean engine oil. Squeeze element to
remove excess oil and to distribute oil thoroughly. An oil
damp element is desirable.
4. When servicing foam element, check condition of paper
element. Replace as required. Do not use compressed air
to clean the paper element.
5. Install foam element, paper element, and air cleaner cover.
Do not operate the engine without the air cleaner element
because extreme engine wear and damage will likely result.

Servicing the Engine Oil

The crankcase must be filled with approximately 34 fl oz (1
L) of proper viscosity oil before starting. The engine uses
any high-quality oil having the American Petroleum
Institute - API - "service classification" SF, SG, SH or SJ.
Oil viscosity - weight - must be selected according to
ambient temperature. (Figure 15) illustrates the
temperature/viscosity recommendations.

Using multi-grade oils (5W-20, 10W-30, and 10W-40) will
increase oil consumption. Check the oil level more
frequently when using them.

Changing the Engine Oil

Service Interval: After the initial 20hours, then every 100
hours after the initial oil change.
1. Start the engine and let it run five minutes. This warms
the oil so it drains better.
2. Place a pan under the oil drain hole.
3. Remove the drain plug and drain the oil.
Dispose of the used oil at a certified recycling center.
5. Install the drain plug and refill the crankcase with the
specified oil. Refer to Checking the Engine Oil Level
(Figure 16).
