ASSEMBLY
WARNING:
To avoid serious personal injury, make sure the
curved front edge of the saw mounting brackets
are securely seated onto the MSUV top rails before
seating the other end of the brackets. Failure to
do so could cause you to lose control of the saw
and bracket assembly, which could cause serious
personal injury.
 Lower the saw and bracket assembly to allow the rear
clamp of the bracket to seat fully over the toprails.
 Lock the brackets in position by lowering the locking
levers.
NOTE: Continue to hold the saw and bracket assembly
with one hand until both levers are securely locked.
 Check position and adjust, if necessary, to make sure the
weight of the saw is evenly balanced over the top rails.
 Ensure the saw is fully seated and locked in position, then
securely tighten the four nuts holding the saw to the saw
mounting brackets.
WARNING:
The saw mounting brackets are designed to fit
snugly over the top rails with locking levers in
the open position. With the locking levers in the
lowered (locked) position, you should not be able
to slide the saw mounting bracket assembly along
the top rails or remove the bracket assembly from
the top rails. If the saw mounting brackets will
not fit over the top rails, or if the brackets can be
removed from the top rails when the levers are
locked, remove bracket assembly immediately
and adjust bracket adjustment screw. See the
Maintenance section of this manual. Failure to heed
this warning may result in serious personal injury.
To remove saw from the MSUV:
 Squeeze locking lever release trigger and raise the locking
levers to unlock the saw mounting brackets assembly.
 Grasp the brackets on either side of the assembly and
lift away from the top rails to disengage.
 With the assembly tilted slightly toward you, lift the front
part of the assembly to disengage from the front edge of
the top rails.

CLOSING THE MSUV
See Figure 16 - 18, pages 16 - 17.
 If a miter saw is assembled on the stand, make sure to
place the blade 90° to the table (if applicable), miter the
blade to the right as far as it will go, lock the saw arm in
the down position, and lock all knobs and levers.
NOTE: ALWAYS move mounted saw opposite the
wheeled end of stand (in the open position) prior to
transporting or taking down unit and ensure saw
mounting brackets are securely locked.
NOTE: If a sliding compound miter saw is mounted on
the stand, it may be necessary to slide the power head/
blade assembly forward and lock in place when going
through doorways or other narrow openings.
 Remove any workpieces, clamps, or other accessories
from the tool.
 Retract support arm. Refer to Using the Support Arms
later in this manual.
 Stand at the wheel end of the MSUV and grasp the handle.
 Step on the release lever. Lift the handle up and away
from the body until the unit rests on the wheels and frame
support and release lever clicks into place. This is the
vertical closed position.
NOTE: You may have to step onto the axle frame between
the wheels to securely lock the release lever into place.
WARNING:
To avoid serious personal injury when raising the
front of the MSUV, bend your knees so you can lift
