Unpacking Your Mobile Base
Safety
While unpacking your mobile base verify that all the components shown on this page are included.
1. Never place ngers, toes or other body parts under the saw when it is raised onto the mobile base. The base
may suddenly lower on you and cause a severe injury.
2. Do not attempt to use or move the saw on an inclined surface. The weight of the saw makes it di󰀩cult to stop
on an inclined surface. Attempting to use or move the saw on an inclined surface could result in a severe injury.
3. Make sure the saw is fully lowered to the ground and stable before operating the saw. Otherwise, the saw could
move unexpectedly and cause a severe injury.
4. Be sure to unplug or disconnect the saw from power before moving or repositioning it. The main power cord or
the power outlet could be damaged if the saw is not disconnected from power before moving it.
Note: If you are using the SawStop Out-Feed Table you must remove it before moving your saw with the Contractor
Saw Mobile Base. Attempting to lift the saw with the out-feed table attached may damage the out-feed table.

1. Locate all of the mobile base components shown on page 1. All of the hardware
needed to install the mobile base is located on the mobile base hardware pack
(see Fig. 1). In order to easily identify the hardware used in each of the following
steps, the di󰀨erent pieces of hardware are numbered on the hardware pack and
in the gures. If you are missing the hardware pack or any of the other mobile
base components, call the SawStop Service Department at 503-582-9934 for
replacements.
You will need the following tools to complete the mobile base installation:
• two 10 mm wrenches
• two 13 mm wrench
• a 14 mm wrench
• a 5 mm hex key
Note: The stand for your contractor saw must be fully assembled before installing the mobile base.
2. Take the wheel support and mount one of the 3
inch wheels to the end furthest from the foot pedal.
Use the short axle, one M6 washer, and one M6
nylon hex nut to mount the wheel to the support
as shown in Fig. 2. Fully tighten the nut using a 10
mm wrench and a 5 mm hex key.
3. Mount the other 3 inch wheel to the other end of the
wheel support. Use the long axle, one M6 washer,
and one M6 nylon hex nut to mount the wheel to
the support as shown in Fig. 3. Do not tighten the
nut because it will be removed in a later installation
step.

4. Each end of the wheel support has a cylindrical projection. Mount the wheel support to the left side of the stand
by inserting the cylindrical projections into corresponding mounting holes in the legs of the stand, and then
securing the support to the stand with two M8 x 20 button head socket screws, two M8 lock washers, and two
M8 washers, as shown in Figs. 4a and 4b. Fully tighten the two M8 x 20 button head socket screws using a 5
mm hex key. When you mount the support to the stand, make sure the foot pedal is extending out to the left.
5. Position the caster support plate on top of the
caster support as shown in Fig. 5. Note that the
connecting lever on the caster support and the
SawStop logo on the support plate both face up.
Secure the support plate to the caster support with
two M6 x 40 hex bolts, two M6 washers, and two
M6 ange lock nuts. Fully tighten the two M6 x 40
hex bolts using two 10 mm wrenches.

6. The caster support must be positioned inside the stand. If your contractor saw is not yet on the stand, then lift
the right side of the stand a few inches o󰀨 the oor and slide the caster support into position between the two
right legs, as shown in Fig. 6a. Make sure that the SawStop logo on the support plate is facing up and that the
connecting lever is on the inside of the stand. If your contractor saw is already mounted to the stand, you can
remove the lower bracket on the right side of the stand and angle the caster support into place as shown in Fig.
6b. Once the caster support is in place, reinstall the bracket that you removed.
7. Each end of the caster support has a cylindrical projection. Mount the caster support to the right side of the
stand by inserting the cylindrical projections into corresponding mounting holes in the legs of the stand, and
then securing the support to the stand with two M8 x 20 button head socket screws, two M8 lock washers, and
two M8 washers, as shown in Fig. 7. Fully tighten the two M8 x 20 button head socket screws using a 5 mm
hex key. Make sure that the SawStop logo on the support plate is facing up and that the connecting lever is on
the inside of the stand.

8. Mount the two casters to the outer corners of the
caster support by inserting the threaded shaft on
the casters through the corresponding holes in the
support and holding the casters in place with two
M10.5 x 25 washers, two M10.5 x 17 lock washers
and two caster nuts, as shown in Fig. 8. Fully
tighten the caster nuts with a 14 mm wrench.
9. Next, install the linkage bar between the wheel
support and the caster support. To do this, remove
the M6 nylon hex nut and the M6 washer from the
axle for the wheel closest to the foot pad (this is
the nut that was not tightened in step 3), but do
not remove the axle or wheel. Locate the linkage
bar and note that it has a non-threaded hole at one
end and a plastic washer glued near the middle of
the linkage bar. Position the linkage bar so that the
plastic washer faces toward the inside of the stand,
and slide the non-threaded hole at the end of the
linkage bar over the exposed shoulder on the axle,
as shown in Fig. 9. Reinstall the M6 washer and
the M6 nylon hex nut on the axle and fully tighten
the nut with a 10 mm wrench and a 5 mm hex key.
10. Connect the other end of the linkage bar to the
connecting lever on the caster support by inserting
the M8 x 15.7 shoulder socket screw through the
hole in the connecting lever so that the hole ts
over the shoulder on the screw, and then threading
the screw into the threaded hole in the linkage bar,
as shown in Fig. 10. Fully tighten the shoulder
socket screw with a 5 mm hex key.

12. The release lever attaches to the foot pedal arm
of the wheel support. The release lever includes
a non-threaded hole, roughly in the middle of the
lever, that aligns with a threaded hole in the foot
pedal arm, as shown in Fig. 12. Place the M10.5
x 14.5 wave washer over the shoulder of the M8
x 17.7 shoulder socket screw. Then insert the
shoulder socket screw through the non-threaded
hole in the release lever so that the hole ts over
the screw’s shoulder, and then thread the screw
into the hole on the foot pedal arm. Fully tighten
the screw with a 5 mm hex key.

shoulders, one with a larger diameter next to the
head, and one with a smaller diameter next to the
threads. Slide one end of the extension spring over
the larger shoulder (see Fig. 13).

14. The end of the release lever opposite the foot pedal
includes a slot. Pivot the release lever until the slot
aligns with the plastic washer and threaded hole
in the middle of the linkage bar. Insert the release
lever locking screw through the slot in the release
lever and thread it into the hole in the linkage bar,
making sure to keep the extension spring on the
screw (see Fig. 14). Fully tighten the release lever
locking screw with a 5 mm hex key.
15. Locate the M8 nylon hex nut and thread it onto the
release lever locking screw to hold the screw in
place as shown in Fig. 15. Fully tighten the nut with
a 13 mm wrench.
16. Stretch the free end of the extension spring over
the end of the M8 x 30 hex screw that extends from
the release lever. Thread the M8 cap nut onto the
M8 x 30 hex screw to hold the extension spring in
place (see Fig. 16) , and fully tighten the cap nut
with two 13 mm wrenches.

Using Your Mobile Base
1. To move your saw with the mobile base, step down
on the foot pedal to raise the saw o󰀨 the oor and
onto the wheels (see Fig. 17). Step on the foot
pedal until the release lever locking screw slides
into the locked position in the release lever. Make
sure that your foot does not come into contact with
the release lever while you are stepping on the
foot pedal to raise the saw, otherwise the mobile
base will not stay in the raised position.
2. Push the saw to its desired location. The mobile
base has two wheels on the left side and two
casters on the right side, and therefore it may be
easier to maneuver the saw by pushing from the
right side.
3. To unlock the release lever and lower the saw back
to the oor, step down on the foot pedal and the
release lever simultaneously (see Fig. 18). Slowly
lift your foot upwards to allow the saw to gently
lower to the oor. Do not step on the release lever
without having your foot on the foot pedal or your
saw will lower to the oor rapidly.

Note: The SawStop Contractor Mobile Base
has been engineered to lift saws with or
without extension tables. You do not need an
additional arm extending out from the mobile
base to support your extension table.
However, if you have a SawStop 30” Out-Feed
Table attached you must remove it before
using the mobile base to move your saw.
