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.
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 10W-30.

2. After draining, reconnect the hydraulic hose to vibrator.
3. Fill oil through breather hole of hand pump. Use
Shell Tellus
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.
Figure 22. Hydraulic Hose
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.
CAUTION - Over-filling the Hydraulic Oil
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.
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.
