Preparation for Assembly
There is more than one way to assemble the mobile
base. Each method has advantages and disadvantages,
depending on the size and weight of the machine that
Corner Bracket
you plan to put on the mobile base. The purpose of this
section is to help you decide which method will work best
for your situation.
If the machine can be lifted, the easiest method is to
assemble the mobile base according to the dimensions of
your machine, and then lift and place the machine on the
corner bracket pads of the mobile base (see Page 5).
Pad
Figure 7. One of four corner bracket pads
If the machine is top heavy or has a narrow base (such as
a drill press), there is an increased risk when moving it
around on a mobile base. To reduce the risk, a mounting
base plate should be used between the mobile base and
machine (see Page 12).
machine will sit on.
If the machine is too heavy to lift into position on the
mobile base, then the base can be built around the
machine. For instructions on how to build the base around
the machine, refer to Page 8.
Note: Anything extending or opening outward within a 3"
high band (see Figure 8) around the base of the machine
may interfere with the installation of the machine on the
base, so be sure to account for that prior to assembly.
3"
Figure 8. Example of 3" high band on
machine base.
Lift heavy machinery carefully and with
the proper equipment. Get assistance
if needed to reduce the risk of lifting
injuries.

Assembling Base & Mounting Machine
1. Mount the two swivel casters to the corner brackets
with threaded posts (see Figure 9), using (4)
M8-1.25 x 16 hex bolts, 8mm flat washers, 8mm lock
washers, and M8-1.25 hex nuts on each.

hex bolts, 8mm flat washers, 8mm lock washers and
M8-1.25 hex nuts on each.

direction that your machine will typically be moved
(see Figure 11). Mounting the fixed casters in the
wrong direction will make it difficult to move your
mobile base.

which the machine will typically be pushed (see
Figure 12).
Note: Wipe a light coat of machine oil onto the top,
bottom, and sides of the rail ends before the next
step to make it easier to slide the rails into the
brackets and simplify later adjustments.

6. Adjust the assembly so the inside dimension fits the
footprint of your machine.
Note: Side rails may be cut down to accommodate
machines with smaller footprints. However,
reducing the length of the mobile base decreases
stability and increases the likelihood of tipping tall
or top heavy machines. Instead, tall or top heavy
machines should be mounted on a base plate (see
Page 12).

Maximum Extension Line
Do not extend the corner brackets beyond the "MAX"
line marked on the rails (see Figure 14). Extending
the brackets beyond the maximum line may weaken
the rail-bracket connections and damage the mobile
base.

Each side rail-to-corner bracket connection must use
both hex bolts, making a total of four bolts at each
corner, as shown in Figure 15. Do not load a machine
onto the base until all of these bolts have been
installed and tightened. Loading a machine onto the
base before completing assembly can result in the
machine falling or tipping over, resulting in serious
personal injury.

brackets.

9. Thread the knobs into the top of each foot post
several turns, then insert a foot into the bottom
of each foot post, as shown in Figure 16. The
magnetized knob shaft should pick up the foot when
it comes in close proximity.
10. Thread the knobs down to raise the swivel casters
off the floor.

11. Lift the machine into position above the mobile base
using any necessary help, and lower the machine
onto the corner bracket pads.

12. Check to make sure the machine is properly seated
on the pads and that there is no sign of stress or
deflection in the mobile base.
— If there is any deflection, immediately remove
the machine from the base and check that all
fasteners have been tightened and the base is
properly assembled. If this does not solve the
problem, double check the weight specification of
the machine and make certain it does not exceed
the load limit listed in Specifications on Page 1.

slide the front rail-bracket assembly from Step 7
under the machine, as shown in Figure 21.
Note: It may be necessary to re-adjust the position
of the rails once the machine is actually on the base
assembly.
Side rails may be cut down to accommodate
machines with smaller footprints. However,
reducing the length of the mobile base decreases
stability and increases the likelihood of tipping
tall or top heavy machines. Base plates should be
constructed for tall or top heavy machines (see Page
12).

Orient the fixed casters so they point in the same

Making a Base Plate
If the footprint of the machine is too small for the mobile
base or the machine doors or fixtures do not clear the
side rails, you can mount it to a base plate, as shown in
Figure 30.
OR
A good quality base plate can increase the standard
footprint of machines, such as drill presses, to make them
1
more stable. The base plate must be at least 1 ⁄2" thick
and made of plywood (do not use OSB, MDF, or particle
board) to hold the weight of the machine.

Note: Use 2" to 21⁄4" long hex bolts.
7. Place your machine on the base plate.
8. Position the machine close to the front or center of
the mobile base, so the mobile base will not be a trip-
ping hazard.
9. Mount the machine to the base plate with lag bolts
and flat washers (see Figure 30); or drill holes
through the base plate and secure the machine with
through bolts, flat washers, and hex nuts.

Using Mobile Base
1. DISCONNECT THE MACHINE FROM POWER!
Lift heavy equipment carefully and
with the proper equipment. Get
assistance if needed to reduce the risk
of serious personal injury.
2. With the machine mounted on the mobile base, turn
the knobs on the corner brackets counterclockwise
so the feet clear the floor by at least 1⁄8".
— If the floor is uneven, retract the feet completely
to eliminate the chance of the pads dragging on
the floor.
3. Check to make sure the pathway is clear of all
To avoid serious personal injury,
keep your hands and fingers clear of
machine base and mobile base pinch
points when placing the machine.
obstructions.
Before moving the machine and mobile base, check
to make sure the pathway is clear of any hoses,
wires, tools or shop debris. An abrupt impact with
an object in the path of travel can lock a wheel and
cause the machine to fall over, resulting in serious
personal injury. Disconnect the machine from any
power supply or dust collection system before
moving.
To reduce risk of serious injury when
using this mobile base:
1. LOCKING FEET. Do not operate the
machine on the mobile base unless
both mobile base feet firmly contact
the floor and raise the base enough
to disable the casters. Using the
machine on the base when it is not
secured could result in a loss of
workpiece control.
4. Push the machine from the lowest possible point to
avoid tipping it over and move it to its new location.
Note: The best control is usually achieved by
pushing on the side with the swivel casters.
2. TIPPING HAZARD. To avoid tipping it
over, push the machine and base at
the lowest possible point and have
an assistant stabilize the machine if
it is large.
— If the machine is large, get an assistant to help
stabilize the machine while it is being moved.
5. Turn the knobs until the feet touch the floor, then
turn the knobs at least an additional half turn. This
will ensure that the major load of the machine is on
the feet rather than on the casters.
3. PINCH HAZARD. Keep your hands
clear of any potential obstructions
between the machine you are
moving and other equipment or
tables that may protrude into the
path of travel.
6. Check the machine to make sure it is stable in its
new location, and make sure the machine is clear of
any obstructions before reconnecting the power and
turning the machine ON.
4. MACHINE STABILITY. Test for
stability after placing the machine
in its new location. Turn the knobs
down enough to move the feet
against the ground, then push on
the machine at several locations,
making sure it is not off balance.
