ASSEMBLY
ADJUSTING THE MITER LOCK LEVER
See Figures 14 - 15.
Prior to squaring the saw blade to the fence, check the miter
lock lever for proper adjustment. The blade must be set at
an "unindexed" miter position other than 0˚, 15˚, 22.5˚, 31.6˚,
and 45˚ to test. In the "locked" position, the action of push-
ing 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 16 - 20.
 Unplug the saw.
 Push saw arm all the way down and lock in transport
position.
 Lift the miter lock lever to unlock the miter table.
