INITIAL START-UP /OPERATION
MIXING
1.On the hydraulic valve, push lever inward (Figure 20) 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.
Figure 20. Hydraulic Paddle Lever
5.Manual dump machines only: When mixing plaster or mortar, the drum lock lever (Figure 21) should be in the horizontal (down) position. (Does not apply to hydraulic dump mixers.)
Figure 21. 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.
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.
