ST-45 PUMP — INITIAL START-UP PROCEDURE

C.Push the Hopper Remixer Control lever “DOWNWARD“ (Figure 31) and observe that the blades (Figure 33) inside the hopper are turning in a clockwise direction (forward).

Figure 33. Hopper Remixer Blades (Rotation)

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 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.

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.

Important Notice! During freezing

temperature after pumping, completely

NOTE drain the water box and cover the hopper. Frozen liquid will restrict the piston travel and cause severe damage to the pump.

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.
