Control of oil level and refreshing pump oil
Check for each use of the machine, the oil with the oil level glass or with the oil
level bar. Oil must stand right with the sign of the oil level glass, if this is not, oil
tops up until the sign. If oil looks milky, consult directly the DiBO technicians.
To refresh oil, work as follows:
• Unbolt the drain plug below the pump.
• Unbolt the tap with the oil level bar.
• Catch all oil in a barge and remove oil like further described in the guide.
• Force up the drain plug there and top up the oil in the breach to the upper
part to on the mark line.
• Force up the tap with the oil level bar there.
• Recommended oil: 1.836.042 (+- 1Ltr, depending the pump).
