  • Page 42: Variable Tilt Feature

    Variable Tilt Feature The ESX truck is equipped with a tilt sensor and upright height limit switch that sends signals to the truck controls. These inputs are used to control the variable tilt features. The full and restricted tilt ranges will differ depending on the Maximum Fork Height (MFH) of the upright.
  • Page 43: Auxiliary Valve Control (Optional)

    Section 3. Operator Compartment and Controls Fork Level The Fork Level function operates by holding the function change but- ton in, located on the multi function control lever, and using your thumb to operate the mini joystick up or down. While holding the function change button depressed, the tilt will stop when the upright is ap- proximately vertical (forks level).
  • Page 44: Plugging

    Plugging / Auto Plugging Plugging is the preferred method of stopping the ESX trucks. Plugging allows you to change direction or stop without braking, by using the reverse torque of the drive motor to slow the truck to a stop. As you are traveling, move the multi function control handle towards neutral or into the opposite direction.

  • Page 59: Positioning Forks And Upright

    Section 5. Operating Procedures Positioning Forks and Upright When driving, with or without a load, it is good practice to always raise the forks slightly and tilt the forks backward. Raising the forks and tilting them back prevents the fork tips from catching on possible obstructions and reduces the wear on the fork blades from striking or dragging on the fl...
  • Page 60: Controlling Speed

    Controlling Speed To move the truck either forward or reverse, move the multi-function handle in the direction that you want the truck to move. Move the handle toward the front of the truck to go forward or toward the rear of the truck to move the truck in reverse.
  • Page 61: Operating Safely

    Section 5. Operating Procedures Operating Safely WARNING Safe operation is the responsibility of the operator. Watch where you are going. Don't go if you can't see. Before driving, check all around to be sure that your intended path of travel is clear of obstructions and pedestrians. While driving, be alert for pedestrians, other vehicles or obstructions in your path of travel.
  • Page 62 Always be in full control of your lift truck... Never operate a lift truck or its attachments if you are not in the desig- nated operator's position. Never operate a lift truck when your hands are wet or greasy. Always pick the smoothest travel route for your lift truck. Avoid bumps, holes, slick spots, and loose objects or debris in your path that may cause the truck to swerve or tip.
  • Page 63 Section 5. Operating Procedures CAUTION Be sure that your truck is the correct fi re safety type for the area in which you are working. The proper type designation for this truck is listed on the nameplate. In areas classifi ed as hazardous, use only trucks approved for use in those areas.
  • Page 64: Adjusting The Load Forks

    Adjusting the Load Forks The load forks are adjustable on the car- riage fork bar. Forks should be spaced as far apart as the load being carried will allow. Both forks should always be the same distance from the center of the fork carriage.
  • Page 65: Traveling With A Load

    Section 5. Operating Procedures WARNING Slack chains mean rail or carriage hang-up. Raise the up- right before you move. If the upright malfunctions in any way or becomes stuck in a raised position, operate the lift control to eliminate any slack chains. Have the truck fi xed by a trained and authorized mechanic.
  • Page 66: Picking Up And Moving Loads

    Watch clearances around the truck and load as you travel. Raise the forks or attachment only to pick up or stack a load. Look out for obstruc- tions, especially overhead. Be aware that exaggerated tail swing, when turning while traveling forward, is a characteristic of lift trucks that are steered by the rear wheels.
  • Page 67: Unloading

    Section 5. Operating Procedures If the forks are longer than the load, move the tips partially under the load without extending beyond the load. Raise the load to clear the fl oor. Back out several inches, or whatever distance is necessary, then set the load down and move forward until the load is positioned against the face of the forks.
  • Page 68: Stacking

    Stacking To put a load on a stack: Approach slowly and align the lift truck and load squarely with the stack. Level the load as the lift truck is nearing the stack using the Fork Level function. Move forward, slowly, until the load is almost touching the stack.
  • Page 69 Section 5. Operating Procedures To move a load from a stack: Approach the stack carefully, truck lined up squarely with the load. With upright vertical, raise the forks to the correct height for freely engaging the load pallet. Adjust fork angle as necessary to fi t squarely under the load.
  • Page 70: After Operating The Truck
