Battery Restraint and Seat Assembly Repair A battery restraint system is installed as a safety device. The function of the battery restraint system, when correctly locked in the down position, is to hold the battery in the battery compartment if an accident causes the lift truck to tip over. The battery restraint is a steel plate that is connected to the frame with a hinge. A sliding latch mechanism locks the battery restraint in the down position for operation. A knob near the hinge unlocks the battery restraint from the frame so the battery restraint can be raised to the up position for access to the battery. The battery restraint is also the support for the seat. A spring brace holds the seat and battery restraint in the up position. The operator must hold the seat assembly with one hand. Use the other hand on the knob to release the spring brace and lower the seat and battery restraint assembly to the operating position. Make sure that the battery restraint is correctly locked to the frame for operation of the lift truck. An additional battery retention bar is used where batteries can be longer. This bar has a hinge fastened to the counterweight and is part of the hood mechanism on lift truck with hoods. The bar is also installed on lift trucks without hoods. Spacers are used inside the battery compartment to prevent horizontal movement of the battery.

WARNING The battery restraint and its latch mechanisms must operate correctly before a lift truck is operated. Make sure the battery has a cover if the lift truck does not have a hood. To operate correctly, the battery restraint plate must be locked in the down position. The battery retention bar (and hood) must be lowered first; then the battery restraint plate is locked in the down position over the bar. The battery must have spacers to prevent movement in any one horizontal direction of 13 mm (0.5 in.) maximum. See Figure 4. Use the knob near the hinge to release the battery restraint plate. Use the handle on the restraint plate to raise the plate and seat. A spring brace will hold the assembly in the up position. If installed, raise the hood. Make sure that the battery cannot move more than a total of 13 mm (0.5 in.) in any one horizontal direction. Make sure the correct spacers are installed to prevent the movement. See your Yale lift truck dealer to replace damaged or missing spacers. If a smaller battery of the correct weight (see nameplate) is installed and the spacers cannot prevent movement, your Yale lift truck dealer has larger spacers. Push the seat and the battery restraint down until the latch locks. Make sure battery restraint is locked securely. Lift on battery restraint to make sure it is latched and will not move.
