SHOP PROCEDURES
Initial Oil Fill
1. Fill all motor cases ( Figure 2-16 ) with oil:
a. Disconnect fittings at highest case drain port (3) in
each motor.
b. Fill each motor case to level of case drain port. Use
new hydraulic oil which has been filtered
through a 10-micron filter.
c. Reconnect fittings.
2. Open vent ports:
a. Remove vent plugs (1, Figure 2-2 ) from top of both
charge filters (2) on cranes prior to s/n 18001082.
NOTE: S/N18001082 and newer - Supercharge pump
and charge filters 1 and 2 replaced with
accessory pump and additional return filter.
b. Remove vent cap (4, Figure 2-2 ) from right end of
charge pressure manifold (3).
c. Remove vent caps (4, Figure 2-2 ) at thermal bypass
valve (5).
3. Make sure both hydraulic tank shutoff valves (15,
Figure 2-2 ) are fully opened.
4. At engine, engage engine clutch ( Figure 2-17 ).
5. Fill hydraulic tank with clean hydraulic oil to FULL HOT
level mark on sight gauge (12,
Figure 2-2 ).
Fill tank through fill port (8a, Figure 2-2 ) or through
power fill coupler (8b).
6. If used, securely reinstall fill cap (8a).
7. Apply 3-5 psi owner supplied air pressure to coupler
(13a,
Figure 2-2 ) or to air valve (13b) in side of hydraulic
tank.
Breather allows 3 psi pressure to remain in tank to force
oil into system.
8. Air pressure forces oil from tank to charge filters. As
suction lines are filling, monitor vent port at top of charge
filters on cranes prior to s/n 18001082. (2,
Figure 2-2 ).
When clear oil appears, install vent plugs (1).
NOTE: S/N18001082 and newer - Supercharge pump
and charge filters 1 and 2 replaced with
accessory pump and additional return filter.
9. Monitor vent ports in end of each charge pressure
manifold (3,
Figure 2-2 ). Install vent caps (4) when clear
oil appears.
10. Monitor vent ports at thermal bypass valve (5,
Figure 2-2 ). Install vent caps (4) when clear oil appears.
Initial Engine Start-Up
Select and confirm SETUP mode.
Disconnect electrical connectors (DIN plugs) at all brake
solenoid valves shown in
Figure 2-16 . Reconnect electrical
connectors (DIN plugs) after all hydraulic system checks are
completed.
Pressure Sender Calibration
Calibrate the pressure senders as instructed in this section.
Charge Pressure Check
Perform charge pressure check as instructed in this section.
1. Attach a 0-600 psi (0-41 bar) gauge coupler on charge
pressure manifold (
Figure 2-18 ).
2. Start engine and run at low idle (1,050 rpm).
3. At diagnostic screens, scroll to each system in order:
• Drum 1 (Main Hoist 1)
• Drum 2 (Main Hoist 2)
• Drum 3 (Whip Line Hoist)
CAUTION
Equipment Damage!
Incorrectly installed filters and fittings will damage pumps
and motors.

Disconnect power to brake valves before beginning
adjustments.
