Hydraulic System Start–up
NOTE:
When initially starting the hydraulic system with
new or rebuilt components such as motors, pumps, or
lift cylinders, it is important that this start–up procedure
be used. This procedure reduces the chance of damag-
ing the system or its components from not purging the
system of air.
1. After the hydraulic system components have been
properly installed and if the traction pump was rebuilt or
replaced, make sure traction pump housing is at least
half full of clean hydraulic oil.
2. Make sure all hydraulic connections and lines are se-
cured tightly.
3. Make sure hydraulic reservoir is full. Add correct oil
if necessary (see Traction Unit Operator’s Manual).
Drain, flush, and refill hydraulic system reservoir and
change oil filter if component failure was severe or sys-
tem is contaminated.
4. Disconnect electrical connector to the fuel stop sole-
noid to prevent engine from starting.
5. After repairs, check control linkage for proper adjust-
ment, binding, or broken parts.
6. Make sure traction pedal is in
neutral
and the cutting
unit switch is
off
. Turn ignition key switch to start; en-
gage starter for fifteen (15) seconds to prime pump.
7. Attach electrical connector to the fuel stop solenoid.
8. Make sure traction pedal is in
neutral
and the cutting
unit switch is
off
. Start engine and run it at low idle. The
charge pump should pick up oil and fill the hydraulic sys-
tem. If there is no indication of fill in 30 seconds, stop the
engine and determine the cause.
CAUTION
Be careful when operating the cutting unit reels.
Contact with the reel or other moving parts can
result in personal injury.
9. After the hydraulic system starts to show signs of fill,
accomplish the following:
A. If a reel motor was replaced or rebuilt, run the cut-
ting units at the minimum speed setting (under no
load) for 10 minutes in
both
directions.
B. If a reel motor drive pump was replaced or rebuilt,
run the cutting units at the minimum speed setting
(under no load) for 10 minutes.
C. If a traction pump or a wheel motor was replaced
or rebuilt, run the traction unit so the wheels slowly
turn for 10 minutes.
10.Operate the traction unit and cutting unit by gradually
increasing their work load to full over a 10 minute period.
11. Stop the machine. Check hydraulic reservoir and fill
if necessary. Check hydraulic components for leaks and
tighten any loose connections.
