PAGE 12 — MVH-R60H— OPERATION AND PARTS MANUAL — REV. #1 (09/09/04)

MVH-R60H — FEATURES

Definition of Plate Compactor

The Mikasa MVH-R60H is a walk-behind, reversible plate compactor design for the compaction of sand, clay 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 soil 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 MVH-R60H produce low amplitude high frequency vibrations, designed to compact granular soils.

The resulting vibrations cause forward motion. The engine and handle are vibration isolated from the vibrating plate. The heavier the plate, the more compaction force it generates.

Reversible Vibratory Plates

Reversible vibratory plates have two eccentric weights that allow a smooth transition for forward and reverse travel, plus increased compaction force as the result of dual weights.

Due to their weight and force, reversible plates are ideal for semi-cohesive soils.

Frequency/Speed

The compactor's vibrating plate has a frequency of 6000 vpm (vibrations per minute). The forward and reverse travel speed of the compactor is approximately 82 ft./minute (25 meters/minute).

Engine

The Mikasa MVH-R60H Reversible Plate Compactor is equipped with an Honda GX120K1SM12 gasoline engine.

Controls

Before starting the MVH-R60H Reversible Plate Compactor, identify and understand the function of the controls and components as indicated on Figure 3.

Moving the times after the engine has been turned off, will cause the lever to be locked in the forward position.

DO NOT try to operate lever forcibly. The direction travel lever will operate normally when the engine is started and the compactor is in action.

Operating the Compactor on High Moisture Content Soil

Compactor traveling speed may drop on soils which contain clay, or other types of soil. Soil with high moisture content can cause the compaction plate to "stick" to the ground (not lifting up off the ground very fast or high).

To rectify this problem, consider 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.

Spark Plug

1. Remove and clean the spark plug (Figure 16).

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.

Engine Oil Replacement:

1. Replace engine oil after the first 20 hours of operation and

every 100 hours thereafter.

2. Oil may be drained more easily when it is warm after

operation.

3. When changing the engine oil, the old oil can be drained by

removing the oil filler cap, and unscrewing the engine oil drain plug located at the base of the engine (Figure 17).

Air Filter

The air filter element should be regularly cleaned. A clogged air cleaner can cause poor engine starting, lack of power and shorten engine life substantially.

1. To clean or replace air filter loosen the wing nut on the air filter housing (Figure 18), remove the cover and take out air filter cartridge. If only cleaning of the air filter is desired blow through the air filter cartridge from the inside, moving a jet of dry compressed air up and down until all dust is removed.

4. Remember to refill engine crankcase with the recommended type of oil as listed in Table 4 (For more details, see separate Honda Owner's Manual).

Replacing the V-belt

1. Remove the belt cover.

2. Engage an offset wrench (13 mm) or the like to vibrator pulley (lower) fastening bolt.

3. 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.

4. Check the clutch and replace as necessary, following the procedures listed in

5. Engage V-belt to lower vibrator pulley and push the V-belt to the left side of the upper clutch and the rotate offset wrench clockwise so that the V-belt moves onto the pulley.

Checking the Clutch

1. With belt cover removed, visually check outer drum of the clutch for seizure and "V" groove for wear or damage.

2. Clean the "V" groove as necessary.

3. Check the clutch lining and shoe for signs of wear. If the shoe is worn, replace the clutch to prevent deficient power transmission and slippage.

Replacing the Clutch

1. Remove V-belt.

2. Remove bolt at engine power output by giving a shock to an engaged wrench (e.g. tapping with hammer) and rotate the bolt counterclockwise.

Checking the Clutch

Figure 20. V-Belt Tension

3. If the V-belt becomes worn or loose, replace the belt. A loose V-belt will decrease the power transmission output, causing reduced compaction and premature wear of the belt.

3. Remove clutch with a pulley extractor.

4. To install a new clutch, reverse steps 1-3.

CAUTION - Over-filling the Hydraulic Oil

Make sure hydraulic oil in hand pump is at a normal operating level. DO NOT over fill. Over filling (excessive oil) will cause excess oil to blow out of breather plug.

Vibrator Oil Check

1. Place the compactor on a flat surface with the handle in the upright (storage) position.

OIL LEVEL

2. Check the oil level by removing the vibrator oil gauge bolt using a 14 mm wrench as shown in Figure23. The vibrator oil level should be maintained between the two markings as

HAND PUMP

shown in Figure 7. If oil is required, replenish using SAE 10W-30.
