MAX POWER
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.
→
Check all fittings for tightness and leaks.
→
The transmission is already filled with oil at the time of delivery.
→
Max Power uses HYPIOD HD 80W/90 oil in the transmission; therefore, fill the
transmission lube oil header tank with similar grade oil. The function of this
lubricant tank is to ensure a constant pressure, as well as a visual control of
the oil-level. The tank should be filled to the ¾ level. Purge air in tube before
fitting the pipe to the RETRACT.
Performing the UP / DOWN tests (standard joystick control panel).
→
Check UP / DOWN operation.
→
This unit has a second function, in that it blocks the turbine in the down
position when thrust is applied.
Move joystick to port or starboard and check that the up/down hydraulic pump
is pushing the turbine down.
Remove the rubber spacers between the turbine and the lifting arm
AFTER LAUNCHING
→
Check for water leaks.
→
Switch on the system power at the breaker and repeat the UP / DOWN tests.
→
Execute a few short left and right manoeuvres to fill the circuits and thereby
purge the system of all air. After each manoeuvre, check and fill if necessary,
the hydraulic tank. Repeat until the level remains stable.
