MAYCO LS450 CONCRETE PUMP • OPERATION MANUAL — REV. #2 (02/23/21) — PAGE 23
Figure 5 and Figure 6 illustrate the locations of the major
components for the LS450 concrete pump. The function of
each component is described below:
1. Tow Hitch Coupler — Requires a 2-inch ball hitch or
a 3-inch pintle. Capable of towing up to 8,000 pounds.
2. Radio Control Antenna — Mounting location for radio
control antenna. Works in conjunction with handheld
radio remote (option).
3. Manifold Access Door — Release the latch and lift
the door to access the hydraulic manifold block.
4. Hydraulic Oil Tank/Cap — Remove the cap to add
hydraulic fluid. Fill with Shell Oil Tellus 46 or equivalent.
5. Hydraulic Oil Filter — This in-tank return hydraulic
filter with a 10-micron, cleanable filter is designed to
remove all particles large enough to cause wear and
job breakdown. Under normal conditions, replace every
6 months.
6. Hydraulic Oil Reservoir Access Covers — Remove
these covers to gain access to the hydraulic oil tank for
maintenance and cleaning.
7. Hopper/Hood — Lift the hood to fill. Concrete from
a ready-mix truck is poured into this hopper. The
hopper can hold 10 cubic feet of concrete with optional
forward/reverse mixer. NEVER put hands or any other
parts of your body into the hopper.
8. Shuttle Cylinder/Guard — Under pressure, the shuttle
cylinder shears concrete passing from the concrete
cylinder to the delivery line during the cycle phase.
ALWAYS keep hands clear of the shuttle cylinder
during operation.
9. Rear Pumping Jack Stand — Use this jack stand
to level and support the rear end of the pump during
operation. NEVER deploy on unlevel ground and
ALWAYS check for firmness of ground.
10. Tires — This trailer uses two ST235/80R16 type tires.
Tire inflation pressure is the most important factor for
tire life. Pressure should be checked to 80 psi cold
before operation. DO NOT bleed air from the tires when
they are hot. Check inflation pressure weekly during
use to ensure maximum tire life and tread wear.
11. Fuel Tank/Cap — Fill with diesel fuel. Fuel tank (cell)
holds approximately 40 gallons (176 liters). DO NOT
top off fuel. Wipe up any spilled fuel immediately.
12. Battery — This unit uses a +12 VDC type battery.
ALWAYS use gloves and eye protection when handling
the battery.
13. Fuel Tank (Cell) Access Cover — Remove this cover
to gain access to the fuel tank for maintenance and
cleaning.
14. Parking Jack Stand — Use this jack stand to level
and support the tow end of the pump.
15. Front Pumping Jack Stand — Use this jack stand
to level and support the rear end of the pump during
operation. NEVER deploy on unlevel ground and
ALWAYS check for firmness of ground.
16. Safety Chains — This pump uses 5/16-inch-thick,
72-inch-long, zinc-plated safety chains. ALWAYS
connect safety chains when towing.
