16) COOLANT LOW Light illuminates when the engine Coolant Level falls below the normal operating range.
(Applies to water-cooled engines only. On air-cooled engines this light is renamed “V-Belt Failure” and will
illuminate if the engine cooling fan drive belt breaks)
17) HYDRAULIC FLUID Light illuminates when the hydraulic fluid temperature exceeds the normal operating
range. (>200°)
18) CYLINDER A ACTIVE Light illuminates when main drive cylinder A is pumping.
20) CYLINDER B ACTIVE Light illuminates when main drive cylinder B is pumping.
3.3 Machine Controls @ Hopper
1) REMIXER FORWARD / REVERSE Lever shifts the Remixer motor between Forward, Reverse, or Neutral.
This control lever is detented to remain in position selected by the operator. This lever is normally in the For
-
ward position so that stiff concrete will be drawn from the walls of the hopper and pushed into the material
cylinders.
Warning
The operator shall carefully determine that the hopper is clear of personnel and/or equipment before engag
-
ing the Remixer.
2) HYDRAULIC JACK STAND Levers control the extending/retracting of the machine support stands. These
control levers are spring returned.
Warning
The operator shall carefully determine that personnel and/or equipment are clear of the jack stand feet be
-
fore extending the Hydraulic Jack stands.
3.4 Hydraulic Fluid Level and Temperature Gauge
Never operate the pump when oil level is below the Low Level mark. Inspection of oil level periodically during
operation and at shutdown is considered good operator awareness. This will protect against accidental loss
of oil. With the motor running, the proper level should be at the High Mark.
Normal range of oil temperature is 100°-160°F. Oil temperature of less than 50°F is in the cautionary
range. The machine should not be operated at full output until the oil temperature is above 50°F, otherwise
hydraulic pump damage may occur. Oil that is below 10°F should be preheated to 50°F ideally but at least
to 20°F prior to starting the engine.
4 Procedures
4.1 Set up
Positioning of the shotcrete pump will, of course, differ from job to job. The operator must determine how
close the machine can be placed to the work location while still providing good access to ready-mix trucks.
After a relatively flat location is found, the outrigger legs must be extended to isolate the machine’s road
suspension from the weight of the loaded hopper.
Warning
The operator shall carefully determine that personnel and/or equipment are clear of the jack stand feet be
-
fore extending the Hydraulic Jack stands.
