414 Lifting Arms
Max EP lubricant may be applied to any UHMW wear pad surface during the performance of routine
planned maintenance. Max EP dries to leave a protective lubricant film that will not damage or be
absorbed by the UHMW material. LabriePlus offers Max EP lubricant in three sizes:
LabriePlus part number FOL01061: Aerosol 12 Oz (340 g)
LabriePlus part number FOL01062: Bottle 18 Oz (540 ml), with hand pump
LabriePlus part number FOL01065: Bulk 5 Gal (20 l)
If arm in/out functions become slow or erratic and the hydraulic system is in good working order and
operating within specifications, the UHMW wear pads should be checked for binding, usually evident
by a “washboard” wear pattern on their surfaces. In this condition, the UHMW wear pads must be
removed, the contacting surfaces completely cleaned, and new wear pads installed.
