UNPACKING

ASSEMBLY & ADJUSTMENTS

UNPACKING

Due to modern mass production techniques, it is unlikely that your King Cananda

Power tool is faulty or that a part is missing. If you find anything wrong, do not operate the tool until the parts have been replaced or the fault has been rectified.

Failure to do so could result in serious personal injury.

1. Remove all loose parts from the carton.

2. Remove the packing materials from around the saw.

3. Carefully lift the saw from the carton and place it on a level work surface.

4. The saw has been shipped with the saw arm locked in the down position. To release the saw arm, push down on the top of the saw arm and pull on the release knob.

WARNING: Do not lift the saw while holding on to the guards. Use the carrying handle.

MITER LOCK KNOB

The saw is supplied almost fully assembled, you must assemble the miter lock knob. Attach the handle by screwing it into position. This handle can be turned to lock the saw at the desired miter angle. Fig.3.

MITER LATCH

It is necessary to push the miter latch Fig.3 down in order to rotate the turntable.

If the latch is released while the table is being rotated, the table will stop at the next positive stop. There are positive stops at 0 and right.

ADJUSTMENTS & OPERATIONS

SELF-RETRACTING ROTATING BLADE GUARD

The rotating blade guard (A) Fig.7 provides protection from both sides of the blade. It retracts over the upper blade guard (B) as the saw is lowered into the workpiece.

DUST BAG

The dust bag fits over the dust bag adaptor at the rear of the saw head. For more efficient operation, empty the dust bag when it is no more than half full.

This allows better air flow through the bag.

Figure 7

DEPTH OF CUT STOP ADJUSTMENT

In its normal position, the depth of cut stop Fig.8 permits the saw blade to cut right through a workpiece.

When the saw arm is lifted, the depth of cut stop (A) Fig.9 can be pulled out so that the depth adjustment screw (B) contacts the stop as the saw arm is lowered. This resricts the cut to a “adjusted depth” in the workpiece. The depth of cut can be adjusted with the adjustment screw and locked in position with the lock nut (C).

BENCH MOUNTING

The saw base has holes to facilitate bench mounting.

1. Fix the saw to the bench using 4 hex. bolts and hex. nuts.

2. If desired, you can mount the saw to a piece of 13mm or thicker plywood which can then be clamped to your work support or moved to other job sites and reclamped.

CAUTION: Make sure that the mounting surface is not warped as an uneven surface can cause binding and inaccurate sawing.
