• n_3 = -422. This setting turns off the low vacuum warning buzzer, light and/or strobe light

and turns on the vacuum lift light, indicating that the lifter has already reached the

minimum vacuum level (see n_4). Setting n_3 must always be set above n_4.

• n_4 = -419. After the vacuum switch has turned off the vacuum pump(s) (see n_1) and the

vacuum system has lost significant vacuum, setting n_4 turns on the low vacuum warning
buzzer, light and/or strobe light and turns off the vacuum lift light. This signals a loss of
adequate vacuum to the lifter operator.
Note: Setting n_4 corresponds with the minimum vacuum level for lifting loads.

This

setting must not be lowered without first consulting Wood’s Powr-Grip, because

it may reduce the maximum lifting capacity.

3) Each vacuum switch must be locked after all adjustments have been made. Use the arrow

keys to access the locked mode (“LoC”) and press the “SET” button again.

4) Repeat steps 1-4 for the other vacuum switch, to ensure the settings are the same.
