unscrew it more than a revolution.
► Keep your face away from the lubricating valve connection.

► Release grease only as described below. (Observe the safety
instructions!)
Excessive tension of the tracks causes severe damage to the
hydraulic cylinder and the track.
► Tighten the tracks only up to the mandatory measuring
distance.
