CAUTION:
Make sure hydraulic oil in hand pump is at a normal save operating level. DO NOT over fill. Over filling (excessive oil) will cause excess oil to blow out of breather plug.
Hydraulic Oil
Check hydraulic oil in every 100 hours of operation. With handle bar positioned vertically (storage position), remove breather plug (Figure 1) off the top of hydraulic pump and check for proper oil level.
Replace hydraulic oil after first 200 hours and in every 1,000 hours of operation.
Replacing Hydraulic Oil
1.After removing plug cap of hand pump (Figure 6), remove plug of breather (24 mm wrench) and disconnect vibrator side of hydraulic hose (Figure 17) at vibrator cylinder. With travel lever placed in the FORWARD position, drain hydraulic oil in the pump.

MVH-150GH/D MAINTENANCE
2.After draining, reconnect the hydraulic hose to vibrator.
3.Fill oil through breather hole of hand pump. (Capacity: About 300 cc). Use ShellTellus Oil #46 or equivalent
4.Removing breather plug at vibrator cylinder causes oil to flow out of breather hole in a while. When aeration disappears, replace the plug and tighten securely.
5.Replace breather plug of hand pump and fit the plug cap. After making sure that oil in pump is at proper level, replace the breather plug.
