PURGE THE HYDRAULIC SYSTEM
If the hydraulic system becomes contaminated because of
component failure or some other reason, you must purge
the hydraulic system.
To purge the system, follow these steps:
1. Extend the packer/ejector cylinder to lower the oil
level in the tank.
2. Remove and replace the in-tank oil filter element in
the tank.
3. Engage the packer/ejector control lever and allow the
oil to circulate through the new filter, cleaning the oil.
Before filling the tank be sure the funnel is clean and 200
mesh (or finer) screen is used to strain the hydraulic oil.
4. Repeat the procedure as necessary until the system
is purged.
If contaminated hydraulic oil reaches the cylinders, the unit
may need to be removed from service until the
contamination is removed. For more information, contact
the Heil Technical Services.
CLEAN AND INSPECT THE TAILGATE SEAL
Periodically check the tailgate seal to make sure it mates
properly with the body and inspect for possible wear,
damage or leaking. Replace the seal as necessary.
