3.2 - Installing the Leveling Feet
Set the machine down in its desired location and determine if the
machine is level, making sure that it does NOT rock in any direc-
tion. If it does, determine which Leveling Feet need to be adjusted
and whether they need to be adjusted up or down.
If adjustment is needed, start by loosening the four (4) nuts which
are accessed through the rear of the machine.
Next adjust the four (4) Leveling Feet by screwing them clockwise
to raise the or counter-clockwise to lower. After each adjustment
set the machine down completely to verify that the machine no
longer rocks. Continue adjustment as needed until the machine
sits securely in place. Tighten the four (4) nuts down to secure the
position of the Leveling Feet.
