v.
Open the swing brake "service" side bleeder valve on the swing drive. Start
the diesel engine, and depress the swing brake pedal to bleed out all regular
oil, until OEA fills the service brake cavity. Re-tighten the bleeder valve.
w.
Open the swing brake "release" side bleeder valve on the swing drive, and
operate the brake release switch to bleed out all regular oil, until OEA fills
the brake release cavity. Re-tighten the bleeder valve.
x.
Loosen the hose connection at the pressure switch which actuates the
SWING BRAKE ON Indicator (26) on the superstructure console. Allow the
regular oil to drain out of the switch, then operate the SWING BRAKE
ON/OFF Selector Switch (18) to bleed out all regular oil in the hose, until
OEA fills the hose and the switch. Re-tighten the hose connection.
y.
With the boom in the rest cradle, loosen the hose connection at the LMI
piston-side pressure transducer. Allow all regular oil to drain out of the
transducer, then barely operate the boom lift control in the "raise" direction,
until all regular oil in the hose to the transducer and in the transducer itself
has been replaced with OEA. Re-tighten the hose connection.
z.
With the boom in the rest cradle, loosen the hose connection at the LMI rod-
side pressure transducer. Allow all regular oil to drain out of the transducer,
then barely operate the boom lift control in the "lower" direction, until all
regular oil in the hose to the transducer and in the transducer itself has been
replaced with OEA. Re-tighten the hose connection.
aa.
Examine the ATEC for any visible leakage from the hydraulic system, and
correct as necessary. Add OEA as necessary to bring the hydraulic
reservoir oil level to "full".
bb.
Disconnect the main hydraulic pump drive.

a.
Extend and lower the outriggers until the wheels are clear of the ground.
Otherwise, the crane must be moved back and forth as necessary to
accomplish step a. below.
b.
Start the engine and place the transmission in gear, or otherwise rotate the
wheels as necessary to bring the drain plugs of the planetary wheels ends to
their lowest position.
NOTE
Depending on the relative positions of the drain
plugs, it may be necessary to perform steps b., c.,
and d. in succession for each wheel end.
c.
Drain all oil from each wheel end, and replace the plug.
