MAYCO LS300P CONCRETE PUMP • OPERATION MANUAL — REV. #1 (02/20/17) — PAGE 23
PUMP COMPONENTS
Figure 5 and 6 illustrates the location of the major
components for the LS300P Concrete Pump. The function
of each component is described below:
1.
Tires
— This trailer uses two ST205-750 x15E 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 insure the maximum tire life and tread wear.
2.
Zerk Grease Fittings
— Top fitting lubricates shuttle
cylinder top, center position lubricates nun plate and
bottom position lubricates shuttle cylinder bottom.
3.
Hydraulic Oil Sight Glass
— Use to determine the
amount of hydraulic oil remaining in tank. The sight
glass also contains a temperature gauge for monitoring
the temperature of the hydraulic oil.
4.
Hydraulic Oil Tank/Cap
— Remove cap to add
hydraulic fluid. Fill with Shell Oil Tellus 46 or Mobil Oil
DFE26 if level is low.
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 break down. Under normal conditions, clean every
6 months.
6.
Air Filter
— Prevents dirt and other debris from
entering the fuel system. Release the latches on the
side of the air filter cover to gain access to filter element.
NOTICE
Operating the engine without an air filter, with a damaged
air filter, or a filter in need of replacement will allow dirt to
enter the engine, causing rapid engine wear
7.
Muffler
— Used to reduce noise and emissions.
NEVER touch the muffler while it is hot! Serious burns
can result.
NEVER
operate the engine with the muffler
removed.
8.
Radiator
— Fill only with recommended coolant.
Radiator coolant capacity is 4.5 gallons (17 liters).
9.
Documentation Box
— Contains engine and pump
operation, parts and maintenance information.
10.
Breakaway Switch/Cable
— Used in conjunction with
the hydraulic actuator. Connect to tow vehicle.
11.
Tow Hitch Coupler
— Requires a 2-inch ball hitch or
a 3-inch pintle. Capable of towing 6,000 lbs.
12.
Safety Chains
— This pump uses 5/16-inch thick,
72 inches long zinc-plated safety chains.
ALWAYS
connect safety chains when towing. ALWAYS cross
chains when connecting to tow vehicle.
13.
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.
14.
Lubrication Box
— This box is empty when shipped
from the factory. Please fill with 3 gallons (11.35 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.
15.
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.
