MAYCO MG-30 PUMP — OPERATION AND PARTS MANUAL — REV. #3 (09/15/11) — PAGE 29
1. Manifold — Cast steel manifold, 2 in. (5.08 cm.) for plaster,
3 inch (7.62 cm.) for fireproofing. This manifold is designed
with a
manual pressure relief valve and an automatic
safety pressure relief valve rated between 700-1000 PSI.
2. Tires — This trailer uses two ST205-750 x14C 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.
3. Mixer — This unit uses a " Essick " mechanical 12 ft 3 mortar
and plaster mixer . See page 27 for mixer component
definitions.
4. Oiler — Cam bearing oiler. Fill with SAE 20 or 30 wt. motor
oil. Lubricates cam surface.
5. Fuel Gauge/Fuel Cap — Read the top of this cap to
determine if the fuel level is low. If fuel level is low, remove
cap to add #2 diesel fuel.
6. Gear Reduction Pulley — This is an adjustable 4-groove
pulley. Select the pulley speed that fits your pumping
requirement.
7. Compartment Hood Lift Handles — There are two
compartment hood lift handles located on each side of the
hood. Grip handle and pull upwards to lift hood.
8. Compartment Hood — This hood encloses the engine,
compressor, gear reduction pulley, reduction gearbox,
battery, control box and other associated components
required to operate the pump.
NEVER! operate the pump
with the hood in the up position.
9. View Access Window — This opening allows the user to
start the unit and have access to the control box without
lifting the compartment hood.
10. Access Cover/Handle — Turn this handle clockwise to
release latch, then lift upwards. When this cover is in the
open position it will provide a more free flow of air to help
keep the engine and associated components cool.
11. Documentation Box — Contains information regarding
the pump and mixer.
12. Speed Reduction Gearbox — A constant-mesh type and
total enclosed gearbox with all gears immersed in oil. Fill
with SAE 90 wt. motor oil.
ALWAYS keep gearbox oil at
proper operating level.
13. Engine Control Box — Contains the engine ignition
switch, operation switch, engine status LED's (5), hour meter,
remote control connector and 25 amp fuse.

14. Piston Oiler Tank— Fill this tank to the " FULL " level for
normal operating conditions. Check regularly. Fill with SAE
30 wt. type motor oil. Oiler tank capacity is 1-1/2 quarts (1.14
liters).
15. Lubrication Port Panel — Central grease panel. All
lubrication points can be accessed via this panel. Allows
lubrication of all bearings without lifting the hood.
16. Hopper — This unit uses a galvanized hopper which can
hold up to 12.0 cu. ft. (340 liters) of mix. NEVER put hands
or any other parts of you body into the hopper.
17. Mixer End Jack Stand – Use this jack stand to level
and support the pump.
18. Lubrication Box Access Cover – There are four access
covers on the pump. Remove these doors to gain access to
drive and piston assemblies when maintenance is required.
19. Gear Reduction Adjustment Bolt – Loosen this bolt to
pivot the gearbox assembly upwards or downwards. This
will allow for the placement of the V-belt on one of the four
pulley grooves.
20. Battery – This unit uses a +12 VDC type battery. ALWAYS
use gloves and eye protection when handling the battery.
21. Air Compressor – This unit uses a piston type Quincy
Air Compressor , driven by V-belts from the engine. This
air compressor supplies air to the nozzle for spraying of
material. The compressor has an output of 10 CFM @ 100
psi. A weekly check should be made of the crankcase oil
level to make sure it is at the
full mark , or at least between
the two marks on the dipstick.
22. Throttle Control Knob – This is a variable speed type
control. Turning the throttle lock (CCW) left unlocks the
throttle allowing the throttle control cable to be pulled out to
the desired position. Once the desired throttle position
(speed) has been achieved, turning the throttle lock to the
(CW) right locks it in place. Use the fine tune adjustment
knob to fine tune the engine rpm's.
To place the engine in idle, press the top button inward all
the way.
23. Engine – This unit uses a HATZ Model 2M4LZ, 35 HP air
cooled diesel engine. See page 31 for engine component
definitions.
24. Tow End Jack Stand – Use this jack stand to level and
support the pump.
25. Tow Hitch Coupler – Requires a 2-inch ball hitch or a
pin. Capable of towing 5,000 lbs.
26. Chock Blocks – Place these blocks (not included as
part of your concrete pump package) under each wheel
to prevent rolling or when parked on a slope.
