Pump Components

Figure 4 illustrates the location of the major components for the C30HDZ Concrete Pump. The function of each component is described below:

1. Discharge Cone – Connect 3" elbow to this discharge port, then connect 3" x 2" reducer to elbow.

2.Discharge Cone Safety Latch – When towing of the pump is required, ALWAYS secure the discharge cone to latch located on the manifold.

3. Rear Running Lights – ALWAYS check and make sure both the right and left running lights are functioning correctly before towing the pump.

4.Hopper – Concrete from a Redi-Mix truck is poured into this hopper. The hopper can hold 6.0 cu. ft of concrete. NEVER put hands or any other parts of you body into the hopper.

5.Safety Grill – The safety grill should be locked at all times when the pump is being towed. Under normal working conditions, raise and place the safety grill on the support hooks which are located on splash guard.

6.Shaft Pulley V-Belt – ALWAYS inspect the drive shaft V-belt for wear and alignment. A defective or misaligned V- belt can wear prematurely and adversely affect the performance of the pump.Replace with only manufactures recommended typeV-belt.

7.Compartment Hood – NEVER operate the pump with the hood removed. Installed on the pump frame is a safety inter- lock device which prevents the engine from starting if the hood is removed or in the up position (open).

8.Hood Fastener – When the hood is in the down position, secure the rubber latch to this fastener.

9.Hood Lift Handle – Grip this handle, pull upward then back to raise the compartment hood.

10.Control Box – Contains the mechanical and electrical components required to run the pump. Below is a list of those components:

■Throttle Control

■Choke Control

■Low Oil Pressure Indicator

■Battery Charge Indicator

■Water Temperature Indicator

■Ignition Switch

■Remote Connector

11. Fuel Tank/Cap – Fill with unleaded fuel. Fuel tank (cell) holds approximately 11 gallons (41 liters).DO NOT top off fuel.Wipe up any spilled fuel immediately

12. Tow End Jack Stand – Use this jack stand to level and support the pump.

13. Tow Hitch Coupler – Requires a 2-inch ball hitch or a 3-inch pintle. Capable of towing 5,000 lbs.

14. Safety Chain – ALWAYS attach safety chain to the towing vehicle. NEVER! tow the pump with the safety chain unattached.

15. Engine Stop Device –This device will prevent the starting of the engine when the compartment hood is in the up position. The compartment hood must be in the down position in order for the engine to start.

16. Grease Port Console – This console allows for the remote lubrication of components on the pump.

17. Access Door – There are four access doors on the pump. Remove these door to gain access to drive and piston assemblies when maintenance is required.

18. Drive Chain – Keep this chain properly lubricated and aligned at all times. Lubricate this chain as specified in the maintenance section of this maintenance.

19. Rubber Latch – Secure this rubber latch to the hood fastener whenever the pump is in use or being towed.

20. Tires Ply– The tire ply (layers) number is rated in letters; This trailer uses 4-ply tires.

21. Chock Blocks – Place these blocks (not included as part of your concrete pump package) under each trailer wheel to prevent rolling.

22. Pump End Jack Stand – Use this jack stand to level and support the pump.

23. Discharge Cone Release Lever – secures the discharge cone to the "Y" manifold; also relieves manifold pressure.

24. Documentation Box – Contains engine and pump operation, parts and maintenance information.

25. Lubrication Box – This box is empty when shipped from the factory. Please fill with 7 gallons ( 26.5 liters) of SAE motor oil for first time use. Also check the dual clean-out point on bottom of lubrication box for a secure tight fit.
