CHECKS, TESTS & ADJUSTMENTS
BEFORE LAUNCHING
IMPORTANT
: Before the launch, verify that the RETRACT unit inspection top plate
has been replaced (if it was removed during installation) and that all the lower flange
bolts have been tightened. Torque for all these bolts is
5 kg/m.
Filling the hydraulic circuit.
MAX POWER recommends the use of
ISO GRADE 15 to 32 hydraulic oils
for the
power circuit. This mineral oil has already been used by Max Power during the run in
tests and consequently the RETRACT motor and piping are already filled with this
kind off oil.
CAUTION
: Biodegradable and mineral (commonly used) oils are non-compatible and
should not be mixed or used together. Mixing them will deteriorate certain hydraulic
elements. If you intend to use a biodegradable oil, thoroughly flush the existing
mineral oil from the RETRACT unit first with the appropriate oil.
Before carrying out the below test we recommend to disconnect the wire at terminal
N° 32 in the control box.
Or if PLC, disable thrust valve!
