PREVENTATIVE MAINTENANCE (PAGE 18)
ROTATOR RLP-902 SPECIFIC ACCUMULATOR
Place grapple on firm level surface, turn off machine & avoid pinch points.
Inspection of Accumulator inside the RLP rotator (For models: SAS EXTREME EX-25 v2 & v3 )
Rotators without case drain line installed require regular accumulator pressure inspection by a profession-
al equipment service technician with a Hydac charging & gauging unit (PN#02068195) or similar device.
Pressure test interval
Perform a pressure check bi-monthly, or at 100 hour intervals. Hour meter and date should be recorded.
Overview accumulator pressure requirement
Accumulator should have 15 PSI. Test at accumulator pressure port, only with proper test kit.
OPTIONAL CASE DRAIN LINE INSTALLATION WILL PROMOTE LONGER LIFE:
From factory the rotator came with an accumulator to relieve pressure. These parts have a life cycle and
can fail. Installing a
case drain (free flow return line) can help prevent damage to motor if accumulator
fails. Extreme units with five hoses have already have the case drain installed.
Installation of case drain line will help prevent damage risk due to pressure spikes to hydraulic motor.
High pressure hydraulics. Stay clear of pinch points to avoid serious injury. Relieve pressure prior to work.
Follow safety precautions in SAS EXTREME Auto Processor Manual prior to work.
