  • Page 62: Changing Hydraulic Oil

    5.2.4 CHANGING HYDRAULIC OIL Every 500 operating hours or annually, whichever comes first, the oil in the hydraulic system and filter should be changed. To change the oil and filter, fol- low this procedure: Run the hydraulic pump until the oil is warm. Warm freshly agitated oil removes more contami- nants when drained than cold stagnate oil.
  • Page 63 5.2.5 SPEED REDUCER GEARBOX OIL Each conveyor is driven by an electric motor that is attached to a high ratio speed reducing gearbox to give the required operating speed. Each gearbox is equipped with a drain, level and fill plug. Every 100 hours, the oil level should be checked.
  • Page 64 5.2.6 CONVEYOR BELT TENSION / ALIGNMENT OR REPLACEMENT Rubber belts are used to convey material with the Telescoping Loader. The tension and alignment of the conveyors should be checked daily to insure proper function. Replace the conveyor belt when damaged or badly worn. To maintain conveyor, follow this procedure: Place all controls in their OFF or neutral position.
  • Page 65 4. Alignment: It is properly aligned when the belt runs in the cen- ter of the frame panels and the shafts. Be sure to run the conveyor a full revolution to check the entire belt. The belt can move from side-to-side while it is turning as long as it doesn't contact the sides.
  • Page 66 5. Replacement: a. Move one or both of the shafts into their loos- est position. b. Open the conveyor by removing the connect- ing rod on the belt lacing. c. Attach the replacement conveyor to the end of the old conveyor. d.
  • Page 67 5.2.7 EXTENDING / RETRACTING ROLLER CHAIN An anchored roller chain is used to extend and retract the boom. The roller chain must be oiled on a daily basis and the tension and alignment checked weekly during the season. When maintaining the roller chain, follow this procedure: Daily oiling: a.
  • Page 68 3. Weekly roller chain tension: Check the tension when the machine is OFF and not moving. The chain should be snug when it is at rest. When checking spring tension, follow this procedure: a. Turn power OFF at the master panel and lock- out before performing any maintenance work.
