MAINTENANCE Quarterly Maintenance (continued) • Remove rear service panel (A) and lubricate the hydraulic cylinder pins (B) with light weight machine oil (see Figure 12): • Lubricate the grease zerk inside the barrier arm (C) white lithium grease (see Figure 12). Failure to properly lubricate the barrier will cause abnormal operation of the barrier.
ADJUSTMENTS Adjust Main Pressure Relief If it is necessary to service the barrier with the arm in the vertical position, engage a safety chain to prevent the arm from falling. In addition, it is recommended and good safety practice to use use an additional means to support the raised barrier arm.
ADJUSTMENTS Adjust Flow Control Flow Control Adjustment Note: The down speed flow control is factory set. If original setting is lost, or if the barrier bounces while lowering, the flow control will require adjustment. When properly adjusted, the barrier arm will smoothly lower from fully raised to fully lowered in 10-12 seconds, without bouncing.
TROUBLESHOOTING If it is necessary to service the barrier with the arm When service is required, always lock all electrical in the vertical position, engage a safety chain to disconnects in the OFF position. prevent the arm from falling. Always post safety warnings and barricade the In addition, it is recommended and good safety work area at dock level and ground level to practice to use use an additional means to support...
