2022 Continental Cargo Auto Plus CARGO TRAILERS Hydraulic Pump Owners Manual

Check the reservoir for proper fluid level (approximately 1/2” from the top of the tank when the dump body is down). If fluid must be added, use a new automatic transmission fluid, Dextron III, or equivalent. Please keep in mind when servicing this unit that the most common cause of system failure is dirt. Keep the service area clean. If a malfunction of the power unit should occur, inspect all hydraulic lines and electrical connections, and check for good ground. Many malfunctions are caused by loose connections. If the unit does not operate at all, malfunction is due to a switch, solenoid, motor, dead battery, corroded terminals, or bad connections at the dump motor package. If the unit operates slowly and/or with low pressure, malfunction is due to a leaking relief valve, clogged filter, worn pump, corroded or bad battery terminals, or fluid that is too heavy. If the unit is unable to hold pressure, malfunction is due to a leaking relief valve. In most cases, a leaking relief valve is caused by dirt. This can often be corrected by pulling the release rod and actuating the key switch at the same time. The high oil flow recirculating to the reservoir will wash the contaminant from the valve. Do not operate the unit when low on fluid.
