MVH-402DSB—MAINTENANCE
Vibrator Oil Level Check
1. In every 100 hours of operation, with the machine positioned
horizontally, remove vibrator oil level check plug (Figure
21) off vibrator (19 mm wrench) and see if oil is up to filler
port. Be sure to clean area around check hole to prevent dirt
and dust from entering.
2. In every 300 hours of operation, replace oil (capacity 1,500
cc). For draining oil through level check hole, have the
machine inclined with a sleeper or the like placed under the
compaction plate on opposite side.
* Use engine oil 10W-30 for this lubrication.
Hydraulic Oil
1. Check hydraulic oil in every 100 hours of operation. With
handle bar positioned vertically (storage position), remove
breather plug (Figure 23) off the top of hydraulic pump and
check for proper oil level.
2. Replace hydraulic oil after first 200 hours and in every 1,000
hours of operation.
Replacing Hydraulic Oil
1. Remove the drain plug (Figure 22) at the bottom of the oil
tank 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 or
Roctite #575 to thread portion.
4. Fill tank with hydraulic oil. (Capacity: About 2,500 cc). Use
Shell Tellus Oil #46
or equivalent.
5. After filling tank, temporarily install cover. Loosen bleeder
plug located at the top of the cylinders on side of vibrator
(Figure 23). Air remaining in the circuit will be forced out of
the bleeder plug.
6. Tighten the bleeder plug. Check oil level in the tank again.
7. Install the cover of oil tank. Coat packing with liquid packing
such as Threebond #1215. Use loctite #242 for mounting
screw.
Make sure hydraulic oil i is at a normal safe operating
level.
DO NOT
over fill. Over filling (excessive oil)
will cause excess oil to blow out of breather plug.
CAUTION:
CAUTION
Always clean the area around the vibrator oil level
check hole before removing oil check plug. This will
prevent dirt and debris from entering the system.
