MVC88GH/GHW PLATE COMPACTOR — OPERATION AND PARTS MANUAL — REV. #5 (01/11/11) — PAGE 11
GENERAL INFORMATION
Definition of Plate Compactor
The Mikasa MVC-88GH/GHW is a walk behind, plate compactor designed for the compaction of sand, mixed soils and asphalt. This plate compactor is a powerful compacting tool capable of applying a tremendous force in consecutive high frequency vibrations to a soil surface. Its applications include compacting for road, embankments and reservoirs as well as backfilling for gas pipelines, water pipelines and cable installation work.
Vibratory Plates
The vibratory plates of the MVC-88GH/GHWproduce low amplitude high frequency vibrations, designed to compact granular soils and asphalt.
The resulting vibrations cause forward motion.The engine and handle are vibration isolated from the vibrating plate.
Frequency/Speed
The compactor's vibrating plate has a frequency range between 5800 vpm (vibrations per minute).The forward and reverse travel speed of the compactor is approximately 23 meters/minute (75 ft./minute).
Engine
The Mikasa MVC-88GH/GHW Plate Compactor is equipped with an Honda air cooled, 4-cycle gasoline engine. The engine drives an eccentric weight at a high speed to develop a compaction force. In addition this engine is equipped with an Oil Alert system that will automatically stop the engine before the engine falls below safe engine oil operating limits. Always be sure to check the engine oil level prior to starting the engine.
Controls
Before starting the MVC-88GH/GHW Plate Compactor identify and understand the function of the controls and components as indicated in Figure 1.

1.Oncetheenginehasstarted, movetheenginethrottlelever quickly to the fast position.
2.With the throttle lever in the fast position, the engine speed should be around 2,300 RPM, therefore engaging the centrifugalclutch.
NOTICE
ALWAYS move the throttle lever quickly without hesitation, because increasing the engine speed slowly causes the clutch to slip.
5.Firmlygaspthecompactor'shandlebar withbothhands,the compactor will begin moving forward.
6.Slowlywalkbehindthecompactorandbeonthelookout for anylargeobjectsorforeignmatterthatmightcausedamage to the compactor or bodily injury.
7.Compactortravelingspeedmaydroponsoilswhichcontain clay, however there may be cases where traveling speed drops because the compaction plate does not leave the ground surface easily due to the composition of the soil.To rectify this problem do the following:
■Check the bottom plate to see if clay or equivalent material has been lodge in the plate mechanism. If so, wash with water and remove.
■Remember the compactor does not work as efficiently on clay or soils that have a high moisture content level.
■If the soil has a high moisture level, dry soil to appropriate moisture content level or carry out compaction twice.
Stopping the Engine
CAUTION
NEVER stop the engine suddenly while working at high speeds.
1.Place the throttle lever (Figure 12) in slow position, and listen for the engine speed to decrease.

CHANGINGVIBRATOR OIL
1.When changing the vibrator oil, remove the drain plug located at the bottomright of the vibrator (Figure 5), 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 replaceing vibrator oil.
CAUTION
NEVER attempt to check theV-belt with the engine running. Severe injury can occur if your hand (Figure 6) gets caught between theV-belt and the clutch.Always use safety gloves.
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
Whenever the compactor's vibration becomes weak or lost duringnormaloperationregardlessofoperationhours,check theV-belt and clutch immediately.
■ Replacing 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 ofV-belt on the left side and while pulling it back strongly, rotate the offset wrench clockwise so that theV-belt will come off.
■ Reinstalling 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.
■ Checking Clutch
Check the clutch simultaneously withV-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.
