11. Safety Rules For Cleaning The Water Box
11.1
Crushing and amputation hazard! Stop the concrete pump
before removing the water box covers. If your unit has bolt down guards, do not
remove them for cleaning. If there is not a bolt-down guard over the water box,
then stop the pump, take the transmission out of gear, and lock the cab so the
pump cannot be restarted until you are finished cleaning and the covers are back
in place. If a bolt-down grate is installed, you may simply stop the pump from
stroking before removing the water box covers. Replace the covers before restart-
ing the pump.
11.2
If possible, position the folded boom in a slightly raised posi-
tion when cleaning the water box (watch for power lines and other wires when
raising the boom). The outriggers must be extended and jacked. If the boom is
raised, it will be unnecessary to bend over the water box for cleaning. Be sure
boom is stowed and outriggers are secured for travel before moving the unit.
11.3
Falling hazard! Be sure of your footing when cleaning the
water box.
11.4
Crushing and amputation hazard! Do not remove the water box
guards for cleaning. Clean the water box with water jets only. Do not put your
hands or any other body part into the water box for cleaning, or at any other
time when the hydraulic system is operational.
12. Safety Rules For Cleaning A Separately Laid Pipeline
12.1
Flying particle hazard! Clear the discharge area of personnel
and equipment before forcing a ball or go-devil through the pipeline, even if you
are cleaning with water. Some air will be trapped in the pipeline, and the trapped
air will become compressed before discharge.
12.2
Short pipelines and single pipe sections should be cleaned by
removing the clamps and dumping the pipe sections. Remember to lift with your
legs, not with your back.
