11. Mixer setting adjustments (cont.)
Calibration – cartridge holder height adjustment
Adjustment should only be performed if multiple sensors and
toggle are significantly out of alignment in uniform direction
(very uncommon).
1. Remove rear panel.
2. On upper section of the mixer, the cartridge holder plate
(knuckle height) should be 2 5/32" from the middle plate.
Measure from bottom side of plate to middle plate.
3. To adjust the height, the locking bolt needs to be
loosened. Twist locking bolt and adjustment knuckle bolt
in opposite directions. Use 17 mm and 13 mm open end
wrench.
4. Turn adjustment knuckle until desired height is achieved.
5. Tighten locking bolt while holding adjustment knuckle in
place with another wrench.
Calibration – toggle switch
The toggle switch is activated at the bottom of the down
stroke. Its proper function allows mixing of the plunger side
in the cartridge. Too low and the mixer may stall or cause
excess movement of the plunger in the cartridge. Too high
and there will be unmixed product near the plunger.
The toggle switch should be approximately 15 to 30 degrees
above the horizontal position at rest, but a horizontal
‘engagement point’ is the critical aspect. The engagement
point can be felt when lightly pressing down on the toggle
switch with your finger. There is a resistance increase that
can be felt at the point when the internal valve is engaged
inside the toggle switch.
If adjustments are needed:
1. Use a 2.5 mm Allen wrench to loosen the underside bolt.
2. Move the toggle to the correct position and re-tighten
bolt. (If lever does not turn on the shaft, use flathead
screwdriver to hold the shaft while moving the lever
manually.)
3. Re-check the engagement point by lightly pressing down
on the lever with your finger to feel a slight resistance to
the lever motion downward. This point should be when
the toggle lever is exactly horizontal.
