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 damaging
the system or its components from not purging the sys-
tem of air.
1. After the hydraulic system components have been
properly installed and if thetractionpumpwasrebuiltor
replaced, make sure traction pump housing is at least
half full of clean hydraulic oil.
2. Makesure all hydraulic connections and lines are se-
cured tightly.
3. Make sure hydraulic reservoir is full. Add correct oil
if necessary. Drain, flush and refill hydraulic system res-
ervoir and change oil filter if component failure was se-
vere or system is contaminated.
4. After repairs, check control linkage for proper adjust-
ment, binding or broken parts.
5. Make sure functional control lever is in neutral.
6. Disconnect both spark plug wires from spark plugs
to prevent the engine from starting.
7. Turn ignition key switch and engage starter for ten
(10) seconds to prime pump.Return ignition switchto off
and wait one (1) minute to allow starter to cool. Repeat
step a second time.
8. Reconnect spark plug wires to spark plugs.
9. Make sure functional control lever is in neutral and
cutting unit switch is off. Start engine and run at low idle
speed. The charge pump should pick up oil and fill the
hydraulic system. If there is no indication of fill in thirty
(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.
10.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 ten (10) minutes in both directions.
B. If the gear pump was replaced or rebuilt, run the
cutting units at the minimum speed setting (under no
load) for ten (10) minutes.
C. If the piston pump or a wheel motor was replaced
or rebuilt, run the traction unit so the wheels turn
slowly for ten (10) minutes.
11.Operate the traction unit and cutting units by gradu-
ally increasing their work load to full over a ten (10) min-
ute period.
12.Stop the machine. Check reservoir and fill if neces-
sary. Check hydraulic components for leaks and tighten
any loose connections.
