Replace the Hydraulic Oil
NOTE: ISO (International Standards Organization) #46/68
Hydraulic Oil (Mobil Fluid #424) is recommend for
year-round use in the hydraulic system.
In very cold temperatures, SAE 5W or SAE 5W-20
oils can be used if the viscosity of the oil will not be
less than 60 SUS (Saybolt Universal Seconds) at
maximum operating temperature. It may be
necessary to use a pre-heater and a longer than
normal warming period at low operating speed to
heat the oil to operating temperature.
To change the hydraulic oil:
1. Fully retract and lower the boom.
2. Retract all outriggers.
3. Operate the hydraulic system until the hydraulic oil is
warm.
NOTE: It is necessary to climb under the crane to drain the
hydraulic oil. Be sure engine is shut off, the ignition
key is removed and chock blocks are in place
before climbing under the crane.
4. Level the crane, engage the parking brake, stop the
engine and remove the ignition key.
