ENGINE OIL REPLACEMENT
1. Replace engine oil, first in 25 hours of operation and every
50 to 100 hours afterwards.
2. Drain the engine oil when the oil is
warm
as shown in
Figure 27.
3. Remove the oil drain bolt and sealing washer and allow
the oil to drain into a suitable container.
4. Replace engine oil with recommended type oil as listed
in Table 3. Engine oil capacity is 1.16 quarts (1.1 liters).
DO NOT
overfill.

curely.
AIR FILTER
1. Remove the air cleaner cover and foam filter element as
shown in Figure 28.
2. Tap the paper filter element (Figure 28) several times on a
hard surface to remove dirt, or blow compressed air [not
exceeding 30 psi (207 kPa, 2.1 kgf/cm
2
)] through the filter
element from the air cleaner case side.
NEVER
brush off dirt.
Brushing will force dirt into the fibers. Replace the paper filter
element if it is excessively dirty.
3. Clean foam element in warm, soapy water or nonflammable
solvent. Rinse and dry thoroughly. Dip the element in clean
engine oil and completely squeeze out the excess oil from the
element before installing.
