CAUTION The pump is designed for a certain flow range, if there is not enough or too much flow going through the pumps, the resulting turbulence and vortices can reduce performance and may damage the pumps or equipment. 18. Fill the pump through the drain port with clean hydraulic oil. Install the drain hose.
CAUTION Never start the engine with closed shutoff valves. Open the shutoff valves before starting the engine to prevent damage to hydraulic components. 19. Connect the suction hose and pressure hose to the hydraulic pump.
Hydraulic Tank 24. Start the engine while operating the lift function. Keep engine speed at idle. 25. Lift the mast until it has almost reached its end of stroke. 26. Lower the mast and keep the engine at idle for about one minute. 27. Repeat Step 25 if the pump has produced a sound that relates to cavitation. 28. Raise engine speed to high idle (1000 – 1200 rpm) and lift the mast until it has almost reached its end of stroke. 29. Lower the mast and keep the engine at idle for about one minute. 30. Return to Step 28 if the pump has produced a sound that relates to cavitation.
CAUTION Use a filtration system when filling the hydraulic tank to prevent dirt and contamination from entering the hydraulic system. If dirt or contamination enters the hydraulic system, damage may occur to the components of the hydraulic system. 20. Fill the hydraulic tank with clean hydraulic oil as specified in the maintenance table. Refer to the manual Periodic Maintenance 8000 YRM 1593. 21. Release the clamp of the suction hose at the pump. Slide the hose partly from its fitting allowing trapped air to escape and tank oil to reach the pump. Reinstall the hose and tighten the clamp. 22. Install the batteries into the battery box.
CAUTION Connect the positive (power) cable first or lift truck damage may occur. 23. Connect the positive (power) and negative (ground) cables to the batteries.
31. Operate each hydraulic function in both directions twice, at high engine speed (1600 – 1900 rpm). Release the function when it has reached its end of stroke. 32. Turn the engine OFF.
WARNING Do not try to locate hydraulic leaks by putting hands on pressurized hydraulic components. Hydraulic oil can be injected into the body and cause personal injury. 33. Check for leaks. 34. Check hydraulic tank oil level. Fill the hydraulic tank with clean hydraulic oil as specified in the maintenance table. Refer to the manual Periodic Maintenance 8000 YRM 1593. 35. Position the right-hand panel on top of the hydraulic tank and install the four washers and capscrews.
