Checking and the V-Belt
After 200 hours of operation, remove the belt cover to check the V-
belt tension (Figure 20).
1. Remove the belt cover.
2. Tension is proper if the belt bends about 10 mm when
depressed strongly with finger between shafts. Loose or worn
V-belts reduces power transmission efficiency, causing weak
compaction and reduces the life of the belt itself.
CAUTION - Checking and Replacing the V-Belt
NEVER attempt to check the V-belt with
the engine running. Severe injury can
occur if your hand gets caught between
the V-belt and the clutch. Always use
safety gloves.
Replacing the V-belt
1. Remove the V-belt cover (Figure 21).
2. Using cutters, simply cut the worn or defective V-belt and
discard.
3. Place one end of the new V-belt onto the upper pulley (clutch
side).
4. Place a 19 mm offset wrench or the like onto the lower vibrator
pulley fastening bolt.
5. Place the other end of the V-belt onto lower vibrator pulley.
Rotate offset wrench clockwise so that the V-belt moves onto
the lower vibrator pulley.
MVH-150D2 — MAINTENANCE
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 18.
Air Filter Cleaning
1. Remove the air cleaner cover and foam filter element as
shown in Figure 19.
2. Tap the paper filter element (Figure 19) several times on a hard

30 psi (207 kPa, 2.1 kgf/cm
2
)] through the filter element from the
air cleaner case side.

Figure 18. Engine Oil (Draining)
NEVER brush off dirt. Brushing will force dirt into the fibers and
cause poor performance in your air filter. 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.
CAUTION - Cleaning the Engine Air Filter
3. Remove the oil drain bolt and sealing washer and allow the
oil to drain into a suitable container.
4. Replace engine oil in the oil tank with recommended type
oil as listed in Table 4. Engine oil capacity is 1.16 quarts (1.1
liter). DO NOT overfill.
5. Install drain bolt with sealing washer and tighten securely.
