LS600 PUMP — TROUBLESHOOTING (PUMP)

The hydraulic troubleshooting procedures listed below are intended for use by individuals equipped with the proper tools and equipment and are familiar with hydraulic systems and safe shop practices. Use the Pump Troubleshooting Table (Table 8) to identify possible causes for the pump’s malfunction. Contact the Multiquip Service department for the proper repair procedure.

DANGER - AMPUTATION RISK

During routine maintenance or removing material blockage, you will be required to put your hand in the concrete cylinders or near the shuttle tube.You are at EXTREME RISK of injury or AMPUTATION if the engine is running or if pressure is in the hydraulic system.

Prior to performing any maintenance on the pump, follow described lock out-tag out procedures. Stop the engine by turning off the ignition switch and remove the starter key. Place a “DO NOT OPERATE” tag over the switch and disconnect the battery. The pressure reading on the

accumulator pressure gauge MUST read ZERO. ALWAYS make sure the accumulator circuit pressure reads

zero prior to performing any maintenance on the pump.

WARNING - HYDRAULIC SYSTEM HAZARD

DO NOT open hydraulic lines or loosen hydraulic fittings while the engine is running! Hydraulic fluid under pressure can penetrate the skin, blind, cause burns or create other potentially dangerous hazards.
