Clearing The System After Mix Set Up

If, for any reason, the mix should set up in the system, the following procedure is suggested:

1.Disconnect the hose from the pump and wash the pump out immediately.

WARNING

Hose Line Pressure

When disconnecting hoses, use extreme CAUTION. The hose is under pressure. Hose could whip and cause severe bodily harm.

2.Reconnect the hose and fill the hopper with water.

3.Reconnect the hose and fill the hopper with water. DO NOT try to push all the concrete out of all of the hose lines at one time.

4.For example: If you had 200 ft. of system out, you would disconnect each hose. Clean it out by pushing water through the first hose connected the pump, then continue progressing through all the hoses, until all the system is clean.

5.If waiting time is excessive, it would be wise to wash out the pump and hoses and start over when the new truck arrives. This can be avoided by being observant to the pump and system, also taking into consideration the above actors (A through D) affecting the mix.

Clearing Concrete Blockage

NOTICE

If you repeatedly pull the throttle all the way out and try to force your pump to push through blockages due to separation of material in the hose or manifold, you will soon have breakdowns and costly repairs which are not covered under warranty.

If a blockage occurs, find where it is and clear it before further pumping. DO NOT increase the engine speed to clear the blockage. Increasing the engine speed will only compound the problem.

If a blockage occurs in a hose, walk the hose until you find the point of trouble. The hose will be soft immediately past the blockage. To clear the blockage:

1.Disconnect the hose at the first coupling past the blockage. Be careful when disconnecting hose. Hose is under pressure. Hose could whip and cause severe bodily harm.

2.Elevate the hose at that point with the blockage area hanging down.

3.Using a hammer, you can pound the downstream edge of the packed area until it is free to flow. Shake all of the sand and gravel out to the end of the hose.

4.Before reconnecting the hose, start the pump and run a small amount of concrete out to the end of the hose. This will assure that all of the separation is out of the hose.

NOTICE

Damaged hoses with internal restrictions can cause blockages.

Clearing Shuttle Tube Blockage

The shuttle tube is plugged if volume at the discharge end of the hose stops and the hydraulic oil pressure gauge reads 4400 psi or more.

To clear a plug in the shuttle tube, great care must be taken as a dangerous condition will exist from pressure build-up inside the shuttle tube. With the shuttle valve, the concrete can be pumped in reverse. Use the following procedures to clear the shuttle tubes.

WARNING

Joint Clamps

DO NOT open any of the delivery system joint clamps during operation. The clamps are under pressure. The clamps, if opened during operation could allow high pressure material to escape and cause severe bodily harm.
