D2057A, D2058A, D2260A Mobile Base Instructions
19. While an assistant lifts up on the back of the
machine, slide the rear fixed caster assembly
onto the side rails of the front rail-corner bracket
assembly so the rear assembly is close to the
machine base, and the corner pads slide under the
machine, as shown in Figure 27.
— If the rear assembly is too narrow or too wide to
fit onto the side rails, loosen the hex bolts that
secure the corner brackets to the rear rail, adjust
the width of the rear fixed caster assembly so it
slides into the side rails, then retighten the hex
bolts.
Note: It may help to place a 6" 2x4 or 2x6 under the
base temporarily if you need to adjust the width
of the rear fixed caster assembly (see Figure 27).
Remove the block after you finish adjustments.
Note: You may need to tap the assembly to slide it
forward onto the side rails and under the machine.

20. Secure each side with (2) M8-1.25 x 25 hex bolt and
8mm lock nut assemblies, as shown in Figure 28.
Note: Thread the hex bolts into the rails but do not
tighten the lock nuts yet.
21. Tighten the knobs enough to raise the corner
brackets, so you can attach the swivel casters in the
next step.
22. Mount each of the two swivel casters to a front
corner bracket using (4) M8-1.25 x 16 hex bolts,
8mm flat washers, 8mm lock washers, and M8-1.25
hex nuts, as shown in Figure 29.
23. Tighten all of the lock nuts.
24. Remove the 2x4's from the mobile base.
25. Assembly of the mobile base is complete.
Note: The feet must not touch the floor when
moving the mobile base, and the feet must be
firmly against the floor in order to operate the
machine.
