Sheet 1: Operating Instructions OPERATING INSTRUCTIONS The Yale OS030BC and SS030BC electric lift trucks have a 3,000 lb. lifting capacity and are specially designed for order picking. The power source is a 24 or 36 volt battery. The operator's platform is elevated with the load. This allows accurate fork positioning and order picking operations. The lift truck can be operated from the standing position with the operator facing either direction. NOTE: Throughout this manual the terms left, right, front and rear relate to the viewpoint of an operator standing in the truck facing the steer/drive tire. The control handle allows the use of one hand to control forward and reverse travel as well as lift and lower. The variable lift/lower control allows the operator the option of varying the lift and lower speeds. The drive motor is stationary to prevent flexing and wear of the power cables. An electrically released, spring applied brake is also provided. Yale Hi-Vis Triplex masts provide excellent visibility for these models. Before attempting to operate this lift truck, carefully read and understand these operating procedures. Make sure the lift truck is in proper operating condition. Be sure all safety devices such as the overhead guard and the tether line and belt are in place and properly secured. The operator should always wear the tether line and belt when operating this unit. No additions, omissions, changes or modifications should be made that will affect compliance to the stated requirements or in any way minimize the effectiveness of the safety devices. OPERATING CONTROLS
Figure 1-1 -OS030BC Truck The numbers and letters in the following descriptions are to be used for component identification. See Figure 1-2 through Figure 1-8. 1. The Instrument Panel includes a Battery Indicator/Hourmeter, a Steering Indicator Gauge, a Battery Power Disconnect, a Slack Chain Warning and the Key Switch. On lift trucks that have optional Wire Guidance a rocker switch and a red light will also be on the instrument panel. The instrument panel is located between the steering wheel and the traction controller. a. The Battery Indicator/Hourmeter illuminates a light emitting diode (LED) bar to display the battery state of charge. Two red, three yellow and five green colored LEDs are arranged from left to right for a total of 10 bars. The far right LED indicates a charged battery. The far left LED indicates a discharged battery. When a properly charged battery is installed in the lift truck, the green LED at the far right of the scale is illuminated. As the battery's state of charge decreases, LEDs to the left are successively illuminated. The illuminated LED moves from right to left and the colors change from green to yellow to red as the battery discharges. The red LED second from the far left will flash indicating a nearly discharged battery. The battery should be charged at this time. If the last two LEDs are alternately flashing, the battery MUST be charged. The lift function will be disallowed at this point. Continued operation with the LEDs flashing can damage the battery,
