Spark Plug

1.Remove and clean the spark plug (Figure 23).

2.Adjust the spark gap to 0.028 ~0.031 inch (0.6~0.7 mm).This unit has electronic ignition, which requires no adjustments.

Changing Vibrator Oil

1.When changing the vibrator oil, remove the drain plug (Figure 7), and simply tip the compactor to drain the oil. Note that the oil will drain more easily while it is hot. Remember to use only 10W-30 motor oil when replacing vibrator oil.

Checking and Replacing the V-Belt and Clutch

1.After 200 hours of operation, remove the upper belt cover to check the V-belt tension.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

NEVERattempt to check theV-belt with the engine running. Severe injury can occur if your hand (Figure 8) gets caught betweentheV-beltandtheclutch.Alwaysusesafetygloves.

Engine Air Cleaner

1.Remove the air cleaner cover and foam filter element as shown in Figure 24.

2.Wash the foam filter element in kerosene or diesel fuel. Then saturate it in a mixture of 3 parts kerosene or diesel fuel and 1 part engine oil. Completely squeeze the ele- ment to remove the mixture and reinstall it back into the air cleaner.

CAUTION

Wheneverthecompactor'svibrationbecomesweakorlost during normal operation regardless of operation hours, check theV-belt and clutch immediately.

zReplacing the V-belt

Remove the upper and lower belt covers. Engage an offset wrench (13 mm) or the like to vibrator pulley (lower) fastening bolt. Engage waste cloth or the like at midway of V-belt on the left side and while pulling it back strongly, rotate the offset wrench clockwise so that the V-belt will come off.

zReinstalling the V-belt

Engage V-belt to lower vibrator pulley and push the V-belt to left side of upper clutch and, in the same manner as in removal, rotate offset wrench clockwise so that the V-belt goes back on.

zChecking Clutch

Check the clutch simultaneously with V-belt checking. With belt removed, check outer drum of the clutch for seizure and "V" groove for wear or damage with your eyes. Clean the "V" groove as necessary. Wear of lining or shoe should be checked with running check. If the shoe is worn, power transmission becomes deficient and slipping will result.
