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. The maximum restricted back tilt is stamped on the truck capacity plate.

Tilt Restriction Indicator
A red indicator on the dash display will be illuminated any time the upright is outside of the tilt restriction area. Tilt the upright forward or backward, to the vertical position, to turn the indicator OFF and have the ability to raise the forks to the maximum height.

Auxiliary Valve 1 Control (Optional)
The operator's thumb on the 4 way mini joystick can activate this operation by moving the joystick forwards or backwards. (Example: If Aux 1 is used for sideshifter, moving the joystick forwards will sideshift the forks to the left. Moving the joystick backwards will sideshift the forks to the right.

Auxiliary Valve 2 Control (Optional)
If your truck is equipped with an optional hydraulic attachment, the operator's thumb on the 4 way mini joystick can activate the second function by moving the mini joystick forwards or backwards while depressing the function change button.

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. The amount of movement of the handle in the opposite direction controls the distance required for the truck to slow to a smooth, controlled stop. The maximum handle movement will result in the shortest stopping distance.

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 floor or ground. See the NOTICE and CAUTION below.

  • Pull back on the multi-function control lever and raise the forks 6 to 8 inches (152 to 203 mm) above the floor.
  • Then, using the tilt control, tilt the forks back slightly to raise the tips. The amount of forward and rearward tilt to be used is governed by the application.

When the upright (carriage and/or load) is raised into a high (elevated) position, the stability of the truck is reduced. Some of the other conditions that may affect stability are: ground and floor conditions, grade, speed, loading, dynamic and static forces and the judgment exercised by the operator. Trucks equipped with attachments behave as partially loaded trucks even when operated without a load on the attachment. Also, improper operation, faulty maintenance or poor housekeeping may contribute to a condition of instability.

Always be in full control of your lift truck.
Never operate a lift truck or its attachments if you are not in the designated 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. If these conditions are unavoidable, slow down and carefully drive past them. Slow down for wet or slippery surfaces. Avoid any sudden movement. Start, stop, travel, steer, and brake smoothly. Operate your lift truck under all conditions at a speed that will permit you to bring it to a safe stop.
