Hydraulic System Start--u p
NOTE: When initially starting the hydraulic syst em with
neworrebuiltcomponentssuchas motors,pumpsorlift
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 the piston (traction) pump was
rebuiltorreplaced,makesurepistonpumphousingisat
least half full of clean hydraulic oil.
2. Makesureallhydraulicconnectionsandlinesarese-
cured tightly.
3. Make sure hydraulic reservoir is full. Add correct oil
ifnecessary(refer to Operator’sManualfor hydraulicoil
recommendations).Drain, flush and refill hydraulic sys-
tem reservoir and change oil filter if component failure
was severe or system is contaminated.
4. Checkcontrollinkageforp roperadjustment,binding
or broken parts.
5. Disconnect electricalconnectortothefuelstop sole-
noid to prevent the engine from starting.
6. Make sure functional control lever is in the neutral
position. Turn ignition key switch to engage starter for
ten (10) seconds to prime t he pumps. Allow the starter
to cool for sixty (60) seconds and then repeat this step
again.
7. Reconnect electrical connector to the fuel stop sole-
noid.
8. Make sure functional control lever is in the neutral
position. Start engine and run at low idle speed. The

tem.Ifthereisnoindicationoffillin30seconds,stopthe
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 the gear pump or a reel motor was replaced or
rebuilt, run the cutting units at the minimum speed
setting (under no load) for ten (10) minutes in both
directions.
B. If a piston (traction) pump or a wheel motor was
replacedorrebuilt,runthetractionunitsothewheels
slowly turn for ten (10) minutes.
10.Operate the traction unit and cutting units by gradu-
allyincreasingtheirworkloadtofulloveraten (10) min-
ute period.
11.Stop the machine. Check reservoir and fill if neces-
sary. Check hydraulic componentsforleaks and tighten
any loose connections.
