11GripWing nutFig.37. Inspection Before OperationClean each part of the machine well to maintain dirt anddust-free condition. Pay special attention to the soilattached to the bottom of the compacting board, enginecooling air inlet, and the carburetor and air cleaner areato keep those parts clean.Check each part for any looseness of bolts. Vibrationcauses bolts to loosen, which might result inunexpected accident or malfunction.Inspect the guard hook, belt cover and anti-vibrationrubber to check the function of speed adjustment wireand speed adjusting lever.Check for oil leakage from the hydraulic pump andhoses.Check the V-belt tension. (See p.19.) The belt shouldhave about 10 15mm of flexibility when pushedstrongly with a finger at the mid-point between theaxes. If the V-belt is loosened, power is not transmittedwell, which reduces compacting force and shortens thelife of the V-belt.Set the engine on a level surface to check the oil level.If the oil level is low, add oil. Use the following engineoil.Quality: Diesel engine oil, Grade CC or aboveGasoline engine oil, Grade SE or aboveViscosity: SAE No. 30 at 20°C and above (summer)SAE10W-30Set the machine on a level surface, then remove the oilgauge of the vibrator. Check the oil gauge to see if theoil is at the specified level. Use engine oil SAE10W-30as lubrication oil.Recommended oil quantity for MVH-206/207/306/406is 600cc. (Fig. 2-1, 2-2)RefuelingDo not expose to open flames while refueling.Do not fill to the rim because the fuel might spill.Wipe off well if a spill occurs.Use clean automotive gasoline or automotive light oilappropriate for the engine.
