MQ-MIKASA MRH-800DS VIBRATION ROLLER — PARTS & OPERATION MANUAL — REV. #3 (02/02/05) — PAGE 29
Engine Oil Replacement:
1. Replace engine oil in the first 25 hours of operation and
every 50 to 100 hours afterwards.
2. Oil may be drained more easily when it is warm after
operation (For more details, see separate engine Owner's
Manual).
Air Filter
1. The air filter element should be cleaned because a clogged
air cleaner can cause poor engine starting, lack of power
and shorten engine life substantially.
2. To clean or replace air filter loosen the wing nut on the air
filter housing (Figure 24) 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.

that release fork starts to move, turn in the nut by one or two
threads. Lock it a this position together with the rear nut.

HYDRAULIC SYSTEM INSPECTION AND SERVICE
1. Check motor and pump for any damage.
2. Check hoses and pipes for proper tightness and make sure
there are no leaks.
3. Check nylon tubes for hydraulic oil intake and drain.
Retighten brass nut if loose and if a leak is detected. If leak
continues after retightening, replace nylon tube, nut and
sleeve.
4. Check oil tank for proper oil level using the hydraulic system
oil level gauge (See Figure 7). Make sure hydraulic oil has
not whitened or emulsified. Whitish color means aeration in
pump. Retighten pipe and correct level of oil. Emulsification
means water in the hydraulic oil. Replace the oil.
CAUTION:
NEVER attempt to check the V-belt with the en-
gine running. Severe injury can occur if your hand
gets caught between the V-belt and the clutch
(Figure 26). Always use safety gloves.
Excessive turning of front nut may cause the
sliding engagement of clutch to take place or
no vibration takes place even when vibration
lever is engaged.
On the other hand, insufficient turn may cause
sliding engagement of clutch even when the
vibration lever is placed in the OFF position or
for vibration to remain engaged.
CAUTION :
ROLLER INSPECTION AND ADJUSTMENT
1. Refer to Table 8 for oil and grease requirements.
2. Check oil tank level daily.
3. Check the machine for oil leak and proper function of lever,
cables, and links daily.
