Page 6: Construction Of Hull Opening & Closing Plate
MAX POWER METAL HULLS: The mounting base may be constructed with the hull or prefabricated, and then welded onto the hull later. IMPORTANT: In both cases, the top surface of the mounting base ( the flange) must be given particular attention and machined perfectly flat in order to accept the « O »... - Page 7 The nylon washers avoid stainless steel contact with the aluminium case. The nuts should be NYLOCK self-locking type. The 4 lifting lugs provided by MAX POWER, should be put in a small plastic bag, along with the hydraulic pipe plugs, for storage and future use by the ships crew .
- Page 8 MAX POWER It may be necessary to readjust the slide bar height so that the Bar engages automatically or so that the bar is not loose when the thruster closes. This is done as follows Loosen the two bolts holding the locking slide guide (F on drawing N°4) and adjust its height by using 19 mm bolt (G).
- Page 9 All the hydraulic power equipment, such as the piping, reservoir, pump, directional valve, etc. should be installed in compliance with the usual rules of accessibility to enable periodic checks and maintenance.

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. -
Page 12: Operation And Use
MAX POWER 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. -

15 min at 20°C Continuous operation: 5 min at 20°C For longer service periods, Max Power recommends an optional heat exchanger and water pump installation to provide extra oil cooling. TROUBLESHOOTING GUIDE PROBLEM : Thrust stops almost immediately after it has been applied. The alarm buzzer comes on and the green light turns off. - Page 14 MAX POWER The RETRACT 440 is equipped with a manual override device which can be used for lowering the RETRACT turbine from the UP to the DOWN position. IMPORTANT never leave the Manuel override screw unscrewed while using the hydraulic up down unit this would result in very serious damage.
- Page 15 MAX POWER 8. Check the entire hydraulic system hoses and connections for possible chaffing and leaks. 9. Every two years, drain the entire hydraulic oil system. Clean and replace filters. 5 YEARS Complete removal of unit and return to factory.
