PUMP COMPONENTS
Figure 5 and Figure 6 illustrate the locations of the major
components for the LS300G concrete pump. The function
of each component is described below:
1.
Tires — This trailer uses two ST225/75R15 type tires.
Tire inflation pressure is the most important factor in
tire life. Pressure should be checked to
50 psi cold
before operation.
DO NOT
bleed air from tires when
they are hot. Check inflation pressure weekly during
use to ensure the maximum tire life and tread wear.
2. Zerk Grease Fittings — Lubrication points for main
hydraulic cylinders and axle crank bushing. Use
Lithium-based EP, Texaco Multifak 20 or Lubriplate
EP-2 grease.
3. Hydraulic Oil Sight Glass — Use to determine the
amount of hydraulic oil remaining in the tank. The sight
glass also contains a temperature gauge for monitoring
the temperature of the hydraulic oil.
4.
Hydraulic Oil Reservoir Access Cover
— Remove
this cover to gain access to the hydraulic oil tank for
maintenance and cleaning.
5.
Manifold Access Door
— Release latch and lift door
to access the hydraulic manifold block.
6.
Radio Control Antenna
— Mounting location for radio
control antenna. Works in conjunction with hand-held
radio remote (option).
7. Fuel Gauge — To determine when fuel is low, visually
read the level of fuel shown on the fuel gauge.
8.
Pumping Pressure Gauge
— Used to monitor
pressure in the concrete cylinders and shuttle tube.
9.
Control Box
— Contains the electrical components
required to run the pump. See Control Box Components
section for component callouts.
10.
Inline Fuel Filter
— Replace or clean fuel filter as
specified in the Maintenance section of this manual.
11.
Oil Filter
— Prevents dirt and other debris from entering
the engine. Service the oil filter as recommended in the
Maintenance section of this manual.
12. Engine Control Unit (ECU) — Communicates with
engine sensors and actuators to ensure optimal engine
performance.
13.
Coolant Reserve Tank
— Supplies coolant to
the radiator when the coolant level is low. Fill to
approximately 1 inch below the top of the bottle.
14. Hydraulic Actuator — This actuator will be activated
in the event of a breakaway. The breakaway cable must
be rigged to the tow vehicle with appropriate slack
that will activate the system if the coupler connection
comes loose.
15. Tow Hitch Coupler — Requires a 2-inch ball hitch or
a 3-inch pintle. Capable of towing 6,000 lb.
16.
Safety Chains
— This pump uses 5/16-inch thick,
72-inch long, zinc-plated safety chains.
ALWAYS
connect safety chains when towing. ALWAYS cross
chains when connecting to a tow vehicle.
17. Battery — This unit uses a +12 VDC type battery.
ALWAYS
use gloves and eye protection when handling
the battery.
18.
Flow Control Valve
— Controlled by the volume switch
located on the control panel. The function of the volume
control is to set the pumping stroke.
19. Lubrication Box — This box is empty when shipped
from the factory. Please fill with 4.4 gallons (16.6 liters)
of SAE 30 motor oil for first-time use. Also check the
dual clean-out point on bottom of lubrication box for a
secure, tight fit.
20.
Heat Exchanger
— Reduces temperature of the
hydraulic oil. The exchanger draws oil from the
hydraulic system into the heat exchanger before
allowing it to flow back into the reservoir.
