Section 3. Operator Compartment and Controls Tilt Control The multi function control handle is equipped with a 4 way mini joystick that is operated with the thumb when the hand is on the multi function control handle. To tilt the forks forward move the mini joystick upward as noted in the illustration.
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.
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).
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.

Section 4. Operator Maintenance and Care Operator Maintenance and Care Contents Daily Safety Inspection ..........4.2 Visual Checks ............4.3 Functional Checks ............. 4.4 Concluding Inspection ..........4.5 CAUTION The Occupational Safety and Health Act (OSHA) re- quires that truck users examine their trucks before each shift to be sure they are in safe working order.
In general, the daily inspection should include the visual and functional checks described on the following pages. As an aid in carrying out this inspection, CLARK has prepared a form called the "Driver's Daily Checklist." We recommend that you use this form to make a daily record of your inspections and truck condition.
Section 4. Operator Maintenance and Care Visual Checks First, perform a visual inspection of the truck and its major compo- nents: 1. Walk around your lift truck and take note of obvious damage that may have been caused by operation during the last shift. 2.
Functional Checks Check the operation of the truck as follows: NOTICE Before performing these checks, familiarize yourself with the operating procedures in Section 5. 1. Test warning devices, horn, lights, and other safety equipment and accessories. 2. With the key switch ON, check the diagnostic display. The diag- nostic display should show the charge remaining on the battery, the hour meter or a fault code.
Section 4. Operator Maintenance and Care Concluding the Inspection Make a record on the " Driver's Daily Checklist' of all the operating and truck problems that you fi nd. Review the checklist to be sure it has been completed and turn it in to the person responsible for lift truck maintenance.

Before Operating the Truck Be sure that you have read and understand the information in this Operator's Manual before operating the lift truck. The Operator's Manual is located conveniently in the operators com- partment. 657059 WARNING • This equipment can be dangerous if not used properly. Safe operation is the responsibility of the operator.
Section 5. Operating Procedures Starting from a Safe Condition Always start from a safe condition. Before operating a lift truck, make sure that: 1. Parking brake is applied. 2. Forks are fully lowered to the fl oor or ground. Parking Brake Forks Down...
Using the Diagnostic Display Your truck has a Diagnostic Display. "88888" should display on the digital readout for about one second after you turn the key switch to ON. This indicates that the digital readout is OK. After one second, either the hour glass symbol or the wrench symbol should come on.
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...
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.
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.
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.
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.
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.
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.
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.
After Operating the Truck Always leave your lift truck in a safe condition. When you leave your truck, or park it, follow these safety rules: • Park in a safe area away from normal traffi c. • Never park on a grade. •...
