ELEVATING AND SUPPORTING SURFACES FOR A SAW WITH NO STAND
Properly secure the saw to a supporting surface.
Failure to provide a sawdust fall-through and removal hole will allow sawdust to build up around
the motor, causing a possible fire hazard and/or motor damage.
Disconnect the tool from the power source!
Position the four mounting holes located on the base of the saw cabinet (two of which are shown at (A) Fig. 14) over
whatever proper support you are using. Then securely fasten the saw to the supports. The saw can be secured by
fastening the stand through the mounting holes with suitable hardware (not supplied).
The saw support must be able to support 300 pounds.
You can also construct a simple elevated support, as shown in Fig. 15.
Use a good grade of plywood with a minimum 3/4" thickness. Do not make the mounting board
from particle board since particle board breaks easily.
A hole must be provided in this support to allow sawdust to fall through.
Square the saw on the sup port ing surface and mark the location to drill four 5/16" holes. (Fig. 15).
Make sure that at least 3" of the plywood extends beyond the saw on all four sides of the base.
Set the saw aside and drill holes at the previously marked locations. Mark an 11" or 12" square centered between the
four mounting holes. Cut and remove the square (Fig. 15).
To elevate the supporting surface, measure two 2x4s (A) Fig. 15 to the width of two opposite sides of the supporting
surface. Attach the supporting surface to the narrow edges of the 2X4s (as shown in Fig. 15) using wood screws (not
provided) in at least three spots (B) Fig. 15 on each side.
Fasten the saw to the surface by inserting suitable hardware (not supplied) through the mounting holes on the saw and
into the previously drilled holes. While using the saw, periodically remove the sawdust build-up from under the saw.
