PROCEDURES
C-4
Replace the Hydraulic Oil
Replacement of the hydraulic oil is essential for
good machine performance and service life. Dirty
oil and a dirty suction strainer may cause the
machine to perform poorly and continued use may
cause component damage. Extremely dirty
conditions may require oil changes to be
performed more often.
1 Fully lower the platform.
2 Remove the base cover from the power unit.
3 Remove the drain plug from the hydraulic
reservoir and completely drain the reservoir into
a container. Properly discard the oil.
4 Remove the power unit. See 3-3, How to
Remove the Power Unit - AC Models or 3-4,
How to Remove the Power Unit - DC Models.
5 Remove the reservoir from the hydraulic power
unit.
6 Remove the magnet from the reservoir and
clean the magnet and reservoir, using a mild
solvent.
7 Install the magnet, then the reservoir.
8 Apply pipe thread sealant to the drain plug and
re-install it in the reservoir.
9 Fill the reservoir with hydraulic oil until the level
is visible in the sight gauge on the end of the
reservoir. Do not overfill.
10 Replace the breather cap with a new one.
C-3
Lubricate the Lifting Chains
Lubricated chains are essential to good machine
performance and safe operation. Extremely dirty
conditions may require that the chains be cleaned
and lubricated more often.
1 Raise the platform to the maximum height.
2 Lubricate each chain with a dry type spray
lubricant.
This procedure will require the use
of additional access equipment.
Do not place ladders or scaffold
on or against any part of the
machine. Performing this
procedure without the proper skills
and tools may result in death or
serious injury. Dealer service is
strongly recommended.
