MAX POWER
CHECKS, TESTS & ADJUSTEMENTS
BEFORE LAUCHING
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 4 kg/m.
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 a 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.
Perform UP / DOWN tests (standard joystick control panel).
→
Check UP / DOWN operation.
→
The up down unit has a second function; 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 puling the turbine down.
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. Do not allow the Electro-pump to run dry.
Warning
All hydraulic systems develop very high pressures. Failure of piping,
connections etc that have been improperly installed, will most likely happen on start
up. Stay clear of these components. Wear eye protection, and be aware that high-
pressure oil can cause major skin damage.
Check the thrust direction :
With the Joystick to the left (port), the vessel should move to port and conversely. If
the direction is not correct, inverse to connectors on the hydraulic distributor.
Note he left and right thrust tests must be made under normal conditions of
use. In other words that means that the batteries are fully charged that the
main engine alternator is running and the batteries are being correctly
recharged. (if Electro-pump)
