addition to the display on R-Touch, oil level and oil temperature can be read at the
inspection glass (1) on the front of the hydraulic oil tank (3). The hydraulic fluid level
should always remain in the range between the centre of the inspection glass and
the upper edge of the inspection glass. Make sure that the oil level in the hydraulic oil
tank is correct at all times. During all work on the hydraulic system, make sure of the
utmost cleanliness!
