Sudden movement of the machine or release of oil under pressure can cause injury to persons on or near the machine.To prevent possible injury, perform the procedure that follows before testing and adjusting the auxiliary hydraulic system.
Personal injury can result from hydraulic oil pressure and hot oil.Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system.Make sure all of the attachments have been lowered, oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand.

Pump Flow Test (1) Gear Pump. (2) Line.
Assemble adapters to the flow meter. Install the flow meter between the gear pump and line (2) .
Start the engine and run the engine at high idle at 2350 50 RPM until the hydraulic oil temperature is at a minimum of 38°C (100°F).
Record the flow rate at the flow meter. The flow rate should be 53 1.2 L/min (14 0.3 US gpm).
If the flow rate is not correct, the pump has failed and the pump should be replaced or repaired.
If the flow rate is correct, remove tooling and reconnect lines.
