The best material for the base plate is a natural
wood plywood (hardwood plywood is best). Avoid
using OSB, MDF, or particle board, as these
materials are generally not strong enough to hold
heavy machinery for a long period of time.
3
⁄4" plywood is recommended to make the base
plate, with the included 40mm flat head screws.
However, 30mm flat head screws are also includ-

ed for use with
3
⁄4", longer flat head screws must be acquired
⁄2 " plywood. For base plates over
separately. Use good judgement to determine the
material that best fits your needs.
Preparing Base Plate for Assembly
The size requirements of the base plate vary
depending on the size and weight of the machine
you plan to put on the mobile base. The purpose
of this section is to help you decide the size of
base plate that works best for your machine.
Operating machinery on an unsecured
mobile base may allow the machine to
shift unexpectedly, which could result in
accidental contact with the cutting device
or other moving parts.
If the machine is top-heavy or has a narrow base,
there is an increased risk of tipping when moving
it around on a mobile base. To reduce this risk,
make your base plate wider than the machine
base (see Figure 2). Always secure the machine
to the base plate for added stability—this will
reduce the risk of tipping the machine over when
moving it around the shop. See instructions for
mounting the machine on Page 5.
To prepare base plate:
1. Measure footprint of machine base.

Plate
Figure 2. Example of wider base plate.
2. Cut base plate to chosen measurements.
— If you plan on making the base plate
the same dimensions as the machine
base, add 1" to the width and the depth.
This extra space will make mounting easier and will hardly be noticeable once the
machine is mounted.
— If you plan on making the base plate larger
than the machine base to increase stability, don't make the base plate so large it
becomes a tripping hazard.
3. Use a corner bracket as a template and mark
mounting hole locations on each corner of the
base plate.

4. Drill
⁄8" mounting holes at marked locations.
Note: Think about the final appearance of
your mobile base. If you are concerned about
how the exposed portions of the base plate
will look in your shop, paint or finish the base
plate before completing the assembly.

Assembling Mobile Base
1. Attach swivel caster to each front corner
bracket with (4) M8-1.25 x 16 hex bolts and
(4) M8-1.25 lock nuts (see Figure 3).
3. Attach foot pedal to each front corner bracket
with M8-1.25 x 50 shoulder bolt and M8-1.25
lock nut (see Figure5).

front corner bracket and attach adjustable
foot with M10-1.5 hex nut to the bottom of
each foot pedal plunger (see Figure4).

5. Slide top plate tabs into left front corner
bracket (see Figure 7). Attach bracket and
top plate to base plate with (3) M8-1.25 flat
head screws and (3) M8-1.25 flange nuts.
Note: 40mm flat head screws are used with
3
⁄4" base plate and 30mm flat head screws are
used with
1
⁄2" base plate.
Adjusting Rubber Feet
The height of the rubber feet can be adjusted
to stabilize the machine. To ensure the machine
does not move during operations, always make
sure the adjustable rubber feet (see Figure 9) are
firmly touching the ground before operating the
machine.
direction machine will typically be moved
(see Figure 8). Mounting fixed casters in
wrong direction will make it difficult to move
mobile base around in small spaces.
(TOP VIEW OF CASTER)
Typical Direction of Movement
To adjust rubber foot height:
1. Loosen hex nut on each foot to allow foot
(see Figure9) to move up or down as needed.

4. Raise foot pedals up to lift rubber feet and move machine (see Figure 10).
3. Position machine near front or center of base
plate, so mobile base will not be a tripping
hazard.
4. Drill mounting holes of appropriate size using
machine stand as template.
Foot Pedal

IMPORTANT: When moving the mobile base, the
rubber feet should not touch the floor. Likewise,
when operating the machine, ensure that the rubber feet are fixed firmly against the floor to provide
stability, without lifting casters.
Mounting Machine to Mobile Base
1. Lower rubber feet to ensure mobile base is secure (see Adjusting Rubber Feet on
Page 4).
2. With the help of an assistant, place machine
on base plate.
5. Secure machine with through bolts, flat washers, lock washers, and hex nuts (see Figure
11).

may result in strains, back
or property damage.
To avoid serious personal injury, keep
hands and fingers clear of machine base
and mobile base pinch points when placing
machine.

Using Mobile Base
1. DISCONNECT MACHINE FROM POWER!
2. With machine mounted on mobile base,
adjust each rubber foot so it clears floor by at
1
⁄8". Refer to Adjusting Rubber Feet on
least
Page 4 for details.
— If floor is uneven, retract feet completely to
eliminate the chance of the pads dragging.
3. Check to make sure machine pathway is
clear of all obstructions.
4. Push machine from lowest possible point to
avoid tipping it over, and move it to its new
location. The best control is usually achieved
by pushing from swivel caster side of base.
— If the machine is large, get an assistant to
help stabilize the machine while it is being
moved.
To reduce risk of serious injury when using
this mobile base:
1. LOCKING FEET. Do not operate machine
on mobile base unless both mobile base feet
firmly contact floor and raise base enough
to disable casters. Using the machine on
base when it is not secured could result in
a loss of workpiece control.
2. MACHINE STABILITY. Test for stability
after placing the machine in its new location.
Adjust feet so they each they touch the
ground, then push on machine at several
locations, making sure it is not off balance.
The hex nuts can be adjusted up to top of
foot assembly to lock foot height setting.
5. Adjust each foot until it touches floor, then
lower each foot at least an additional halfturn. This ensures major load of machine is
on feet rather than on casters.
6. Check machine to make sure it is stable in
its new location, and make sure machine is
clear of any obstructions before reconnecting
power and turning machine ON.
Before moving machine and mobile base,
check to make sure pathway is clear of
any hoses, wires, tools or shop debris. An
abrupt impact with an object along path of
travel can lock a wheel and cause machine
to fall over, resulting in serious personal
injury. Disconnect machine from power
supply or dust collection before moving.
