5. Let the pump cycle until the hydraulic oil temperature
(Figure 30) is approximately 50° to 60° F.

6. The
accumulator pressure gauge
read approximately 1750 pounds per square inch (psi).

are rotating in a clockwise direction (forward). To
make the blades rotate in a counterclockwise direction
(reverse), push the hopper remixer control lever
upward

9. Place the volume control switch (Figure 27) in the
increase volume position (right) to increase the volume
to 25-30 strokes per minute. Slowly discharge the
concrete from the ready-mix truck into the hopper and
completely fill it. Keep the pump running continuously
until concrete is discharging at the end of the delivery
system. If the pump is stopped during this procedure,
a blockage may occur.

CAUTION
HOSE/LINE BLOCKAGE
If hoses or lines are blocked for any reason, or if the
lines are kinked when starting up or during the pumping
cycle, the pump pressure could straighten out the kink
or force out the blockage. This rapid surge of material
could cause the lines to whip or move in a manner that
could cause injury to personnel.
