MIXING
1. On the hydraulic valve, push lever inward (Figure 23)
for clockwise mixing rotation of blades.
2. The paddle shaft inside the drum should be rotating at
this time.
3. Add a small amount water to the mixing drum.
4. Lift the mixing bag compound onto the steel safety
grate over the bag cutter and let the contents fall into
the drum. Add more water if desired and mix compound
to desired consistency.

WARNING — Dump Handle Safety
ALWAYS stand clear of the dump
handle when the mixer is operational.
Any binding of material between the
mixer blades and the drum will cause
the drum handle to quickly move and
could cause severe bodily harm.
Figure 23. Hydraulic Paddle Lever
Figure 24. Drum Lock Lever
When the drum lock lever is placed
horizontally, the drum will be maintained in
the vertical position as the paddles rotate.
This condition does not apply to models that
have hydraulic dump capability.
