Maintenance and Inspection
13.2 Mainte nanc e instructio ns
WARNING
-
All inspection and maintenance
procedures must be performed after the jack has been
removed from service. Failure to do this may result in
personal injury and/or property damage
.
Check oil level in the reservoir.
All warning and capacity labels should be readable and
complete. Wash external surfaces of lift, labels, and
decals with a mild soap solution. Do not use a pressure
washer to clean the control box. Contact the
manufacturer for replacement labels as needed
.
Inspect battery terminal connections to make sure they
are clean and residue free
.
Apply grease to the grease fittings for the down stop
catch pawl and check that it rotates forward and
backward freely. Refer to the “Periodic lubrication”
section below
.
Inspect structure for damage to contact surfaces,
excessive wear, damaged or cracked welds and/or any
abnormal conditions that could affect performance of
the lifts (See “Structural inspection” section).
Wide models only: Apply grease to the threads on the
carriage adjustment screw
.
13.3 Adding hydraulic fluid
The hydraulic reservoir is mounted inside the lower cover
(Fig. 17, Pos. 5)
.
1.
The lift carriage must be in the fully lowered position and
the lift unit must be on a level surface
.
2.
Remove the lift unit from service and turn the master
on/off switch to
OFF
.
3.
Open the door by releasing the latch on the right side
.
4. Clean around the surface of the oil fill plug to prevent
contamination of the hydraulic oil system.
5.
Visually check the hydraulic oil level. The fluid level
should be within a range from the bottom of the word
“MONARCH” to 1” below the bottom of “MONARCH”.
If the fluid level is low, remove the oil fill plug (See Fig
.
17, Pos. 4) and add a high-grade hydraulic fluid
equivalent to Phillips 66 Megaflow AW22 HVI. Do not
overfill the reservoir. An air gap is required at the top for
fluid expansion and to prevent spilling when moving the
lift unit
.
Do not use brake or transmission fluid. Use of the wrong
fluid can deteriorate the seals and corrosion problems
will occur
.
6.
Re-install the oil fill plug. Clean up any spilled oil and
close the door. Test the lift unit for normal operation
.
If the lift carriage does not rise to full height before the
pump cavitates, check for air in the system. See “Bleeding
air” section for instructions on how to bleed air from the
hydraulic system. If this does not solve the problem,
contact the manufacturer using the information on the
back of this manual
