Fig. 9) and move motor and sanding table
toward the horizontal position. Do not lock.
3. Tension eccentric block by tightening the
nyloc nut (B, Fig. 9) with a 14mm wrench.
Turn the nut in ¼ turn increments and test
locking handle for proper tension. Locking
handle
is properly tensioned when it

eccentric block (attached to the locking
handle) from one side to the other.
The
platen and motor assembly must stay in a
locked position without sliding once the
handle has been moved to the locked
position. Re-adjust as necessary.
