ASSEMBLY
ADJUSTING THE MITER LOCK LEVER
See Figures 17 - 18.
Prior to squaring the saw blade to the fence, check and align
the miter lock lever. The blade must be set at an "unindexed"
miter position other than 0˚, 15˚, 22.5˚, 31.6˚, 45˚, and 60˚ to
test. In the "locked" position, the action of pushing the miter
lock lever down should feel tight and secure. Considerable
effort should be required to move the miter table. If the table
moves easily when in the "locked" position, an adjustment
of the miter lock lever is required.
To adjust:
 Unplug the saw.
 Lift the miter lock lever to unlock.
 Locate the set screw under the miter lock lever.
 Using a hex key, adjust the set screw until the proper
amount of tension in the lock lever is attained.
 Once all adjustments have been made, push the miter
lock lever down to relock the miter table.
SQUARING THE SAW BLADE TO THE FENCE
See Figures 19 - 23.
 Unplug the saw.
 Loosen the screws holding the throat plate and move
the throat plate as far away from the saw blade as
possible.
 Pull the saw arm all the way down and lock in transport
position.
 Lift the miter lock lever.
