The Mikasa MVH-502DSB is a walk behind, reversible platecompactor designed for the compaction of sand, clay andasphalt. This plate compactor is a powerful compacting toolcapable of applying a tremendous force in consecutive highfrequency vibrations to a soil surface. Its applications includesoil compacting for road, embankments and reservoirs as wellas backfilling for gas pipelines, water pipelines and cableinstallation work.
Vibratory Plates
The vibratory plates of the MVH-502DSB produce low amplitudehigh frequency vibrations, designed to compact granular soils.
The resulting vibrations cause forward motion. The engine andhandle are vibration isolated from the vibrating plate. The heavierthe plate, the more compaction force it generates.
Reversible Vibratory Plates
Reversible vibratory plates have two eccentric weights that allowa smooth transition for forward and reverse travel, plus increasedcompaction force as the result of dual weights.
Due to their weight and force, reversible plates are ideal forsemi-cohesive soils.
Frequency/Speed
The compactor's vibrating plate maximum frequency is 4000vpm (vibrations per minute). The forward and reverse travel speedof the compactor is approximately 75.5 ft./minute (23 meters/minute).
Engine
The Mikasa MVH-502DSB Plate Compactor is equipped with aHATZ 1D81S diesel engine.

Remove soil and clean the bottom of compaction plate.
Check hydraulic pump, piping and hose for any leakage. Aloosened hydraulic hose can be a cause for leakage. Checkhydraulic hose connections with wrench applied fortightness.
Check engine oil.
CAUTION:Inspection and other services should always becarried out on hard and level ground with theengine shutdown.
CAUTION:These inspection intervals are for operation undernormal conditions. Adjust your inspection intervalsbased on the number hours plate compactor is inuse, and particular working conditions.
CAUTION:
Fuel piping and connections should be replacedevery 2 years.
1. Replace engine oil, first in 25 hours of operation and every50 to 100 hours afterwards.
2. Oil may be drained more easily when it is warm afteroperation (For more details, see separate engine Owner'sManual).
Air Filter
1. The air filter element should be cleaned because a cloggedair cleaner can cause poor engine starting, lack of powerand shorten engine life substantially.
2. To clean or replace air filter loosen the wing nut on the airfilter housing (Figure 18), remove the cover and take out airfilter cartridge. If only cleaning of the air filter is desired blowthrough the air filter cartridge from the inside, moving a jet ofdry compressed air up and down until all dust is removed.
Reinstalling the V-belt
Engage V-belt to lower vibrator pulley and push the V-belt to leftside of upper clutch and, in the same manner as in removal,rotate offset wrench clockwise so that the V-belt goes back on.
Replacing the V-belt
Remove the belt cover. Engage an offset wrench (19 mm) or thelike to vibrator pulley (lower) fastening bolt. Engage waste clothor the like at midway of V-belt on the left side and while pulling itback strongly, rotate the offset wrench clockwise so that the V-belt will come off.
Checking Clutch
Check the clutch simultaneously with V-belt checking. With beltcover 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 checkedwith running check. If the shoe is worn, power transmissionbecomes deficient and slipping will result.
Replacing Clutch
Remove V-belt. Remove bolt at engine power output by giving ashock to an engaged wrench (tapping with hammer or the like)and rotating bolt counterclockwise. Remove clutch with a pulleyextractor. To reinstall, reverse the procedure.
CAUTION:Whenever the compactor's vibration becomesweak or lost during normal operation regardless ofoperation hours, check the V-belt and clutch imme-diately.

CAUTION:NEVER attempt to check the V-belt with the enginerunning. Severe injury can occur if your hand getscaught between the V-belt and the clutch (Figure19). Always use safety gloves.
Checking and Replacing the V-Belt and Clutch
1. After 200 hours of operation, remove the belt cover to checkthe V-belt tension (Figure 20). Tension is proper if the beltbends about 10 mm when depressed strongly with fingerbetween shafts. Loose or worn V-belts reduces powertransmission efficiency, causing weak compaction andreduces the life of the belt itself.
1. In every 100 hours of operation, with the machine positionedhorizontally, remove vibrator oil level check plug(Figure 21) off vibrator (19 mm wrench) and see if oil is up tofiller port. Be sure to clean area around check hole to preventdirt and dust from entering.
2. In every 300 hours of operation, replace oil (capacity 1,500cc). For draining oil through level check hole, have themachine inclined with a sleeper or the like placed under thecompaction plate on opposite side.
* Use engine oil 10W-30 for this lubrication.
Hydraulic Oil
1. Check hydraulic oil in every 100 hours of operation. Withhandle bar positioned vertically (storage position), removebreather plug (Figure 23) off the top of hydraulic pump andcheck for proper oil level.
2. Replace hydraulic oil after first 200 hours and in every 1,000hours of operation.
Replacing Hydraulic Oil
1. Remove the drain plug (Figure 22) at the bottom of the oiltank with a 6 mm hex wrench and drain the hydraulic oil.
2. Clean the filter with light oil.
3. Reinstall the drain plug to the oil tank. Apply seal tape orRoctite #575 to thread portion.
4. Fill tank with hydraulic oil. (Capacity: About 2,500 cc). UseShell Tellus Oil #46 or equivalent.
5. After filling tank, temporarily install cover. Loosen bleederplug located at the top of the cylinders on side of vibrator(Figure 23). Air remaining in the circuit will be forced out ofthe bleeder plug.
6. Tighten the breather plug. Check oil level in the tank again.
7. Install the cover of oil tank. Coat packing with liquid packingsuch as Threebond #1215. Use loctite #242 for mountingscrew.
Make sure hydraulic oil i is at a normal safeoperating level. DO NOT over fill. Over filling(excessive oil) will cause excess oil to blow out ofbreather plug.
CAUTION:
CAUTION:Always clean the area around the vibrator oil levelcheck hole before removing oil check plug. Thiswill prevent dirt and debris from entering the sys-tem.
See Tables 8 (engine) and 9 (plate compactor) on proceedingpages for troubleshooting guide.
