10. It is important that once the slurry procedure is
completed, and concrete is flowing through the hose,
DO NOT stop the pour until all the slurry is pumped
out and the concrete has reached the end of the hose.
The only reason to stop the pump during the priming
procedure is if a blockage occurs.
11. If it is necessary to replace or add a section of delivery
system, after the initial lubrication procedure, wet the
inside area of the hose, pipe or elbow with 5 gallons of
water per 25-foot length, before adding it to the system.
REMOTE CONTROL (OPTIONAL)
The LS450 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 (radio) or
a hardwire method, which utilizes a 25-foot extension cable.
Contact the MQ Sales Department to order a remote control.

NOTICE
When pumping long distances or pumping stiff mixes,
expect a drop in volume compared to shorter lines or
wetter mixes due to the change in valve efficiency or
cavitation.
