To clean the waterbox, start by lowering the engine
RPM to an idle. Leave the waterbox cover in place, for
now. Open the drain and allow the existing water to
flow out the bottom. When water stops flowing, give
the unit a stroke or two in either forward or reverse.
This will force the water in the extended cylinder back
into the waterbox, and therefore out of the drain. The
waterbox is empty when no more water flows out of the
drain, even after the unit is cycled.
STOP THE PUMP
and secure it against unintentional starting by pushing
the emergency stop button. Be sure of your footing.
Remove the waterbox covers, and spray the waterbox
and cylinders until all cement fines and grout are loose
(Figure 39).
If you will not be filling the waterbox again until just
before the next pour (a highly recommended practice),
then you should do the following procedure:
• Replace the waterbox cover.
• Put the pump into “FORWARD” or
“REVERSE” for 1 or 2 strokes, to force the
clean water out of the drain.
• Close the drain.
If you need to refill the waterbox immediately, simply
close the drain, and finish filling the waterbox. Don’t
forget to replace the waterbox cover before restarting
the unit.
IMPORTANT!
If the machine will be tran s ported or s tored in below freezing
temperature s , you mu s t drain all the water out of the waterbox.
