ASSEMBLY
SECURING THE MSUV TOP RAILS TO THE
CENTRAL BRACE
See Figure 7, page 14.
 Raise the unit so that it rests on its wheels and frame
support. This is the vertical closed position.
NOTE: Do not place the unit in the vertical closed position
until the frame support is installed and all previous
assembly procedures have been followed.
 Align the holes in the brackets with the holes in the central
brace as shown.
 Insert bolts through the holes in the bracket and central
brace.
 Place nuts onto bolts and tighten securely, do not over
tighten.
WARNING:
To reduce the risk of injury, make sure MSUV top
rails are secured to the central brace. Failure to
secure the top rails could cause instability during
use resulting in possible serious injury.
OPENING THE MSUV
See Figure 8 - 9, page 14.
 Stand at the wheel side of the MSUV and grasp the
handle.
 Step on the release lever and pull the handle toward you
at the same time.
 Ease the MSUV toward the floor by pushing the handle
toward the floor until the MSUV is in an open position.
NOTE: The release lever will close over the center brace
locking the stand in an open position.
ATTACHING SAW TO THE MOUNTING
BRACKETS
See Figures 10 - 11, page 15.
Always position the saw to achieve maximum balance and
stability. All four corners of the saw must be bolted to the
saw mounting brackets before use. Make sure bolts do not
extend above the table of the miter saw.
NOTE: Two sets of bolts have been provided for use when
securing saws to the mounting brackets. Use the M8 x 30
set or the M8 x 50 set depending on the height of the saw.
NOTE: Ensure that saw mounting brackets can be clamped
securely onto stand before mounting saw. If locking lever on
saw mounting bracket cannot easily be pushed down into
the closed position, the adjustment screw is too tight. Do
not force locking lever into the closed position. Loosen the
adjustment screw. Refer to the Maintenance section later in
this manual for mounting bracket adjustment.
If the saw has mounting holes that line up with the slots
in the saw mounting brackets:
NOTE: The holes should align so that the brackets are
parallel to each other when mounted.
 Disconnect the saw from power supply and lock the saw
arm in the down position.
 Place two 2 x 4 or similar type of stable support
underneath the saw to raise the saw and allow access
to the saw's mounting feet.
 Place the saw mounting bracket underneath the raised
side of the saw, and insert bolt through bracket slots and
mounting holes in saw.
NOTE: The saw mounting brackets should be placed so
that the lock levers face the front of the saw.
 Loosely secure in place using a flat washer, lock washer,
and hex nut.
 Insert second bolt through bracket and saw, then loosely
secure.
 Repeat procedure to attach second bracket to saw.
 After making sure both brackets are parallel to each other,
lightly tighten all four nuts to hold in position.
If the saw has holes that do not line up with the slots in
the saw mounting brackets:
 Disconnect the saw from power supply and lock saw arm
in the down position.
 Mount the saw to a mounting surface at least 1/2 in. thick
using bolts, washers, and nuts (not included).
 Drill holes in the mounting surface to match the position
of the slots in the saw mounting brackets.
 Proceed with installation as previously described.
MOUNTING THE MITER SAW TO THE MSUV
See Figures 12 - 13, page 15.
WARNING:
Do not mount miter saw to the MSUV before
ensuring the MSUV can be opened and locked
securely. Failure to do so may result in possible
injury and damage the tool.
 Make sure the mounting bracket lock levers are in the
unlocked position.
 Lift the saw and bracket assembly, allowing the assembly
to tilt slightly toward your body.
 While still tilted toward you, place the front end of the saw
and bracket assembly onto the the top rails so the front
clamps of the bracket assembly seat fully over top rails.
