Section 5 – Procedures

5.5 Turret

Maintaining the hydraulic components and hydraulic
oil at the proper level are essential to the good
performance and service life of the MEWP .

5.5-1 Hydraulic Oil Replacement

1. Park the MEWP on a firm level surface in the
stowed position.
2. Allow the hydraulic oil to warm up.
3. Disconnect one of the main power connectors.
4. Place a suitable container under the hydraulic
tank.
5. Remove the oil drain plug and allow all of the
hydraulic oil to drain into the container.
6. Reinstall the drain plug with a new seal ring and
tighten the plug firmly.
7. Refill the hydraulic tank with new oil. Refer to
Hydraulic Specifications.
8. Check for leakage.
9. Clean up any oil that may have spilled during
this procedure.
10. Check the hydraulic oil level. The hydraulic oil
level should be at or slightly above the fill line on
the tank.
NOTE
Refer to your national/local regulations on how to
dispose of used filter and oil.
NOTE
Samples of hydraulic oil should be drawn from
the reservoir and tested annually. These samples
should be taken when the oil is warmed through
normal operation of the system. The sample should
be analyzed by a qualified lubrication specialist to
determine if it is suitable for continued use. Oil change
intervals will depend on the care used in keeping
the oil clean, and the operating conditions. Dirt and/
or moisture cotamination will dictate that the oil
should be changed more often. Under normal use
and operating conditions, the hydraulic oil should be
changed every two years. For oil specifications, refer
to 2.9 Hydraulic Specifications.
