DESCRIPTION OF OPERATION The frame is a welded assembly with mounts for the counterweight, overhead guard, mast, steering system, side panels, hydraulic system and transaxles. See Figure 3. The hood opens on hinges to provide access to the battery compartment. The weight of the battery is a major part of the counterweight system on this truck. A slot in the overhead guard permits removal of the battery without removing the overhead guard. Spacers may be added around the battery as required on some models.

The hydraulic pump and motor assembly and hydraulic tank are in the counterweight. The counterweight cover is removed for access. The AC drive motors and transaxles are located under the floor plates in the operator compartment. The floor plates are held in position by tabs and are to be removed to give access to components underneath. The hydraulic control valve is fastened to the front of the battery compartment and has covers to protect the control valve and control linkages.

Each lift truck has a cast-iron counterweight appropriately weighted for the indicated capacity on the nameplate.

DISCHARGING THE CAPACITORS WARNING DO NOT make repairs or adjustments unless you have been properly trained and authorized to do so. Improper repairs and adjustments can create dangerous operating conditions. DO NOT operate a lift truck that needs repairs. Report the need for repairs to your supervisor immediately. If repair is necessary, attach a DO NOT OPERATE tag on the steering wheel and disconnect the battery. Disconnect the battery and allow the capacitors to discharge before opening any compartment covers or inspecting or repairing the electrical system. DO NOT place tools on top of the battery. If a tool causes a short circuit, the high current flow from the battery can cause personal injury or property damage. Some checks and adjustments are performed with the battery connected. DO NOT connect the battery until the procedure instructs you to do so. Never wear any metallic items on your fingers, arms, or neck. Metal items can accidentally make an electrical connection and cause injury. Before performing any tests or adjustments, block the lift truck to prevent unexpected movement. The capacitor in the transistor controller(s) can hold an electrical charge for about 10 seconds after the battery is disconnected. To prevent an electrical shock and personal injury, discharge the capacitor(s) before inspecting or repairing any component in the drive unit compartment. Make certain that the battery has been disconnected.

Covers and Floor Plates 3. Disconnect the battery by separating the connectors. 4. Block the drive wheels to prevent the lift truck from moving. 5. Make sure the Emergency-Disconnect switch HAS NOT been activated. If the EmergencyDisconnect switch is activated, rotate the switch to the right until it pops up. 6. Push horn button. Wait 30 seconds to be sure capacitors are fully discharged.

RAPID CHARGE The lift trucks covered in this manual may be equipped with a Rapid Charge System (see Figure 4). With a Rapid Charge System, the battery is charged during operator breaks or when the truck is not being used. The rapid charge system provides extended operation with a single battery. Some of the features of the Rapid Charge System include: •

Battery connector externally mounted for easy access

Vented side covers for improved battery cooling

Requires rapid charge vented battery and sealed battery fan box with thermostat

DO NOT short across the motor controller terminals with a screwdriver or jumper wire. Make certain the Emergency-Disconnect switch has not been activated. This will isolate the controller and prevent the capacitors from discharging properly. The proper way to disconnect the battery is by separating the battery connectors. 1. Ensure the capacitors are discharged by performing Step 2 through Step 6 below.

Hood and Seat Assembly

0100 YRM 1329

Hood and Seat Assembly The hood is the platform for the seat assembly and is located above the battery. It functions as a battery restraint that completely covers the battery compartment. See Figure 10. When correctly locked to the frame, it will hold the battery in the battery compartment if an accident causes the lift truck to tip over. The hood is a stamped steel cover. Two hinges at the back attach to the overhead guard. A latch assembly on the front bulkhead locks the hood closed during operation. A gas-controlled strut holds the hood in the open position. See Figure 10 for lift trucks manufactured before November, 2014 See Figure 11 for lift trucks manufactured after November, 2014 Opening the latch assembly unlocks the hood from the frame so the hood can be raised to access the battery. The latch assembly must be in good condition and properly secured before the lift truck can be operated. To raise the hood on a lift truck with manual hydraulics, the manual hydraulic lever and linkage assembly must be moved. Pull latch handle under manual hydraulic cover toward the seat, allowing the lever and linkage assembly to drop forward out of the way. See Figure 8. If the sliding latch assembly does not lock the hood in the closed position, the lever and linkage assembly will not lock into position and the lift truck will not operate. A large, red push-button switch is mounted on the lever and linkage assembly for manual hydraulics and in the armrest console for the electro-hydraulics. This switch is an emergency battery disconnect that allows the operator to quickly disconnect the battery while seated on the lift truck in case of an emergency. See Figure 8.

12


0100 YRM 1329 The seat assembly slides on seat rails that are fastened to spacer plates (Figure 9) and hood by four capscrews. A lever at the left front side of the base controls the adjustment of the seat to the forward and backward positions. Optional seats are available in cloth or vinyl with features such as non-suspension, full suspension, and limited swivel. All seats have a seat switch installed in the bottom cushion that senses operator presence. When the operator is not on the seat, the seat switch opens and interrupts the controller stopping operation of the lift truck as follows: •

After 1.5 seconds, hydraulic functions will cease to operate.

The lift truck, through regenerative braking, will slowly come to a complete stop.

Hood and Seat Assembly Checks and adjustments for the operator restraint system are described in the Operating Manual or See Periodic Maintenance 8000YRM1339 for lift truck models •

Counterweight Replacement WARNING DO NOT operate the lift truck if the capscrews for the counterweight are not installed. The counterweight is a structural member of the truck chassis. The counterweight cannot be removed without first supporting the frame. If the capscrews are not properly installed the counterweight will not support the lift truck. A one-piece, cast iron counterweight is used to offset the weight of the load and support the rear suspension of the lift truck, see figures indicated below. The weight of the counterweight is shown in the tables below. See Figure 14 and Table 1 for lift truck models •

ERP16-20VF (ERP30-40VF) (A955)

A compartment space, accessed by removal of the counterweight cover, has been designed to house the hydraulic tank, hydraulic pump and motor, hoist controller, and electrical connections. A battery platform is used to support the battery on the lift truck frame. The battery platform also serves as part of the counterweight system and requires the use of an overhead lifting device for removal or installation. Be sure to replace the same battery platform, or one of equal weight, if the platform must be removed.
