Checking the hydraulic oil
Notice!
Hot hydraulic oil expands, therefore check the oil only when cold
☞Park the machine on level ground
☞Retract all hydraulic rams
☞Secure the machine to prevent it from rolling away and stop the engine
➥– see chapter 3 “Parking brake” on page 3-50
☞Check the hydraulic oil level in sight glass A
☞If the oil level is visible in the lower half of the oil level sight glass
➥OK
☞If the oil level is no longer visible in the oil level sight glass (not enough oil)
➥Add hydraulic oil
Adding hydraulic oil
Notice!
Do not add hydraulic oil unless the engine is stopped. Otherwise, hydraulic
oil will overflow at the filler opening on the hydraulic reservoir.
☞Proceed as follows:
• Park the machine on level ground
• Retract all hydraulic rams
• Secure the machine against rolling away and stop the engine
– see chapter 3 “Parking brake” on page 3-50
• Open the engine cover
• Clean the area around the filler and breather filter B with a cloth
• Place a container to collect the oil as it drains
• Open breather filter B by hand
With the filter insert in place
• Add hydraulic oil
• Check the hydraulic oil level in the oil level sight glass (fig. 176/A)
• Add if necessary and check again
• Firmly close breather filter B by hand
Notice!
Any excess quantity of hydraulic oil in the reservoir escapes via the breather
as soon as the temperature rises!
• Drain the hydraulic oil if the oil level is no longer visible in the upper half of
the oil level sight glass
