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
25-ft. extension cable. The manual remote cord (Figure 35)
should be installed under the main control box. Contact
your MAYCO representative for further information.

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 5
inches or about ½ 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 ½ 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.
