Hydraulic System
Cutting Units Raise, But Will Not Stay Up
NOTE: Lift cylinders and check valves cannot provide
an absolutly perfect seal. The lift arms will eventually
lower if left in the raised position during storage. It is rec-
ommended that the machine be stored with the cutting
units in the lowered position. This also prevents acci-
dental lowering of the cutting units if the lift lever (joy-
sitck) is bumped while the key switch is on.
Cause
Correction
S5A leaking down (not seating properly).
Reelmaster 6700–D only – S6B affects No. 6 and 7
cutting units.
Do cartridge valve service procedure for valve S5A.
Replace S5A with a new valve if faulty.
ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ
Excessive internal leakage in lift cylinder(s).
ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ
Check lift cylinder(s) and repair or replace if faulty.
Front Outer Cutting Units Lower Too Fast or Too Slow
Cause Correction

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ
One-way variable orifice not properly adjusted (#4 and
#5 cutting units only) - see Hydraulic Schematics.

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ
Adjust variable orifice for affected circuit.
Cutting Units Will Not Lower
Cause Correction
S5A not shifting.
Reelmaster 6700–D only – S6B affects No. 6 and 7
cutting units.
Do electrical diagnostics to make sure that voltage is
being applied to solenoid for affected circuit and that
there is no electrical fault. See Chapter 5 – Electrical
System.
Do cartridge valve service procedure for valve S5A.
