Operating the Auto-Filler Unit
Connect the two hoses to the tractor to operate the auto filler. Warning! Ensure all persons are standing clear
before operating the arm.
1. Check that the Auto filler is operating correctly and become very familiar with the hydraulic system before
attempting to fill a vacuum tank.
Ensure that the arm lowers into the filling hopper, the vacuum pump changes to the fill position and the hydraulic
gate valve opens. The gate valve closes and the vacuum pump changes to the spread position when the arm is
being lifted. Set up the speed that the arm of the filler unit lowers by adjusting the outer flow valve of the three.
The pump change-over can be operated independently of the arm and gate valve by closing the ON/OFF tap under
the flow valves. If at any stage the flow valves must be closed fully note down the colours these valves were set at
before closing fully so that they can be reset to the same position.
2. With the arm working correctly the vacuum tank can be filled as follows:
Connect the suction hose to the filling hopper and lower the opposite end of the hose into the storage tank. Drive
the tanker forward and while lowering the arm locate it in the filling hopper.
With the arm seated in the hopper (Note: Do not force maximum pressure down on the hopper with the ram)
engage the tractor P.T.O. and ensure the pump has changed to the fill position and the hydraulic gate valve has
opened fully. The rubber coupling will create a water tight seal (using the Tank Vacuum) once the Auto filler
hydraulic gate valve is opened, and the tank will fill with slurry after a few minutes.
When the tank is full, slowly lift the arm and the hydraulic gate valve will close. Disengage the tractor P.T.O. and
then lift the arm fully into its transport position. The vacuum pump will change to spread as the arm lifts fully.
Warning! Always ensure that the filling arm has lifted completely into its transport position. The tank can then be
used to transport and spread the slurry. Caution! Never allow pressure to build up in the tank after spreading,
because lowering the arm with the tank pressurised may cause any remaining slurry to be released (under
pressure) through the arm.
