Instructions for using the Flow Test Kit
1. Open loading valve by rotating counter-clockwise.
2. Start pump momentarily to ensure that oil flows freely through the hydraulic system, then
run pump at maximum speed. Do not change pump speed while turning the loading valve.
3. Slowly close the loading valve to develop the desired pressure. Run the machine until
normal operating temperature is reached i.e. typically +45°C...+60°C (+155°F...+140°F).
4. Open the loading valve to read the flow at minimum pressure.
5. Close loading valve slowly to increase pressure and note reduction of flow as the pressure
is increased to maximum pump pressure to determine pump condition.
