Components (Pump) - MULTIQUIP MAYCO Series Operation Manual

Figure 5 illustrates the location of the major components
for the C30HDGA 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. Compartment Hood — NEVER operate the pump with
the hood removed. Installed on the pump frame is a safety
interlock device which will disable high speed if the hood
is removed or in the up position (open).
7. Hood Fastener — When the hood is in the down position,
secure the rubber latch to this fastener.
8. Hood Lift Handle — Grip this handle, pull upward then
back to raise the compartment hood.
9. Control Box — Contains the mechanical and electrical
components required to run the pump. Below is a list of
those components:
• Throttle Control Switch
• Pumping Control
• Check Engine Indicator
• Hood Open Indicator
• Engine Hour Meter
• Ignition Switch
• Remote Connector
10. Radiator/Cap — Fill with a water/anti-freeze type solution
as recommended in the maintenance section of this
manual. ALWAYS make sure that the radiator is filled to
the proper operating level before starting the engine.
11. Fuel Tank/Cap — Fill with unleaded fuel. Fuel tank (cell)
holds approximately 11 gallons (42 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 Safety Device — This device will return the
engine speed to idle if the compartment hood is in the
up position. The compartment hood must be in the down
position for the pump to operate at high rpm's.
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.

aligned at all times. Lubricate this chain as specified in
the maintenance section of this maintenance.
19. Steel 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
