Hydraulic Oil Check
Check hydraulic oil in every 100 hours of operation.
1.With handle bar positioned vertically (storage position), remove the breather cap (Figure 8) from the breather plug.
2.Use a 24 mm wrench and remove breather plug (Figure 21). Visually check to see if hydraulic oil comes up to the oil level
line that is etched on the back side of the handle.

2.If the hydraulic oil level is low, replace with "Shell Tellus" oil #46 or equivalent.
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 22), remove plug of breather (24 mm wrench) and disconnect vibrator side of hydraulic hose (Figure 22) at vibrator cylinder. With travel lever placed in the FORWARD position, drain hydraulic oil in the pump.

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.
CAUTION -
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.
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 shown in Figure 7. If oil is required, replenish using SAE

NOTE
ReplacingVibrator Oil
Always clean the area around the vibrator oil level check hole before removing oil check plug. This will prevent dirt and debris from enter- ing the system.

2.After draining, reconnect the hydraulic hose to vibrator.
3.Fill oil through breather hole of hand pump.Use ShellTellus Oil #46 or equivalent.
4.Removing the vibrator cylinder breather plug causes oil to flow out of breather hole for a while. When aeration disappears, replace the plug and tighten securely.
The vibrator oil should be replaced every 300 hours of operation using engine oil
