Note: When moving the mobile base, the rubber
feet should not touch the floor. However, when
operating the machine, ensure that the rubber feet
are fixed firmly against the floor to stabilize the
machine.
Adjusting Rubber Feet
The height of the rubber feet can be adjusted to stabi-
lize the machine. To ensure the machine does not move
during operations, always make sure the swiveling caster
wheels (see Figure 21) are not touching the ground before
operating the machine.

should not touch the floor. Likewise, when operating
the machine, ensure that the rubber feet are fixed
firmly against the floor to provide stability.

(see Figure 21) to move up or down as needed, then
re-tighten each hex nut.
