Adjusting Low Lift Height; Locking The Lifting Rams During Service - Vaderstad Rapid RDA 400S Original Instructions Manual

3.15 Adjusting Low lift height

Figure 3.34
Low lift height can be adjusted by moving the reed switch up or down in its holder using the wing
bolt (A) which is tightened using the wing nut (B).
This setting must be exact. The Low lift height must not be set either too high or too low.
NOTE!
Too high a setting reduces the pressure on the following harrow in the headlands (unless this is
required). Too low a setting means that tool bars and discs do not have sufficient ground clearance
when raised.
Too low a setting can also cause malfunction of Autostep in the Control Box.

3.16 Locking the lifting rams during service

Figure 3.35
Never work beneath the drill during service or maintenance without first ensuring that it is safely
supported on stands and that all lifting rams are locked. There is 1 lifting ram to control sowing
depth of the drill and one push rod ram (extra in certain markets).The rams can be locked using
the relevant yellow locking devices. Raise the drill to the topmost position and push the stop (A)
onto the master ram towards the cylinder end until the pin slips into place.
Regarding placement of trestles, see "5 Maintenance and service" on page 90.
Service work on the hydraulic system must always be done with the wing sections out and the drill
lowered to the ground.
