D. Push the Hopper Remixer Control lever “UPWARD“ (Figure
32) and observe that the blades (Figure 33) inside the
hopper are turning in a counter-clockwise direction
(reverse).
OPTIONAL RADIO REMOTE CONTROL
14. The MAYCO ST-45 Concrete Pump has a remote control
feature that allows the pump to be remotely controlled. If
desired, the pump can be operated via a receiver/transmitter
method (Figure 34) or a hardwire method, which utilizes a
7.62 meter (25-ft.) extension cable. The manual remote
cord (Figure 35) should be installed under the main control
box. Contact your MAYCO/MULTIQUIP representative for
further information.
C. Push the Hopper Remixer Control lever “DOWNWARD“
(Figure 32) and observe that the blades (Figure 33) inside

CYLINDER LUBRICATION BOX
WARNING
Before checking lubricaton level, stop the
engine and remove the engine starter key.
We recommend using soluble type oil (water
& oil mixture). The oil level should be
checked every day prior to pumping. The oil
level should be maintained at a height of 12.7
cm (5 inches) or about half the concrete
cylinder height.
15. As the rubber piston cups naturally wear, fine cement
particles will accumulate in the box. Once the concrete paste
reaches a height of about 1.3 cm (1/2-inch) from the bottom.
The box should be drained and cleaned. To clean, remove
the drain plug located at the bottom of the box.
Once the box is drained, start the engine and stroke the
cylinder (keep hands out of box) ten to fifteen times. While
stroking, spray water inside of the box to thoroughly clean
out all contamination. When the box is clean, replace drain
plug, add new lubrication and install the top cover.
Important Notice! During freezing
temperature after pumping, completely
drain the water box and cover the
hopper. Frozen liquid will restrict the
piston travel and cause severe
damage to the pump.
