7. Lubrication and Maintenance
Maintenance
Regular maintenance and inspection will help
ensure
trouble-free
unnecessary downtime, and extend the life of
your ProAll Mobile Mixer. Keeping your mixer
clean and free from cement build-up helps to
maintain a good image to your customers. The
operator should perform a daily pre-operation
check, inspecting the truck and mixer for any
mechanical defects.
Speed Sensor
If equipped, ensure the GAP SPACE between the
speed sensors and shafts are set to 0.1 inch
(2.5mm). Speed sensors are located on the left-
hand side conveyor shaft at the rear of the
machine, on the cement auger drive shaft and
the colour feeder if equipped.
NOTE: The sensor must align with the center of
the shaft. Misalignment will result in sensor
reading errors.
Take Up Bearing
Ensure the take-up bearing has a ¼ inch gap
between the washer and tubing as shown in
Figure 18.

Oil
In this hydraulic, the optimum viscosity range is
16 – 36 cSt (75 – 168 SUS), at normal operation
temperatures. Viscosity should never fall below
10 cSt (47 SUS.) At the lowest expected start-up
temperature, the viscosity – less than one
minute – should not exceed 1600 cSt (7500 SUS.)
