7.6 Connecting the metering slide actuator
7.6.1 Connecting the hydraulic slide actuators: Versions K/R/D
Tractor requirements
Versions K: Two single-acting control valves
Versions R: One single-acting control valve
Version D: Two double-acting control valves
Function
The metering slides are actuated separately by two hydraulic cylinders. The hy-
draulic cylinders are connected to the slide actuation on the tractor via hydraulic
hoses.
Attachment
1. Depressurise the hydraulic system.
2. Remove the hoses from the brackets attached to the frame of the machine.
3. Insert the hoses into the corresponding couplings on the tractor.
Instructions for connecting a two-way unit
The two-way unit
is connected to version R as standard.
is offered as optional equipment for version K.
When using the two-way unit, the hydraulic pipes between the hydraulic cylinders
and the slide controls are additionally sheathed with a protective hose in order to
avoid injury to the operator caused by hydraulic oil.
Version Hydraulic cylinder Operation
K Single-acting hydraulic cylin-
ders
Oil pressure closes, spring

R Single-acting hydraulic cylinder
with two-way unit
Oil pressure closes, spring

D Double-acting hydraulic cylinder Oil pressure closes, oil pres-
sure opens
NOTICE
Version K and R
Before extended road travel or during filling, close the two ball cocks at the hy-
draulic pipe plugs. This prevents the automatic opening of the metering slide
caused by valve leakages in the tractor hydraulics.
