Compound mitre cut

Compound mitre cut

 

v

A compound mitre cut

 

involves using a mitre angle

 

and a bevel angle at the

 

same time (fig. v). It is used

 

in making picture frames, to

 

cut mouldings, making boxes

 

with sloping sides and for roof framing. Always make a test cut on a piece of scrap wood before cutting into the good material.

Use the slide action when cutting wide workpieces.

1.Pull on the release knob (6) and lift the saw arm to its full height.

2.Loosen the mitre lock (25).

3.Rotate the mitre table (21) until the pointer aligns with the desired angle on the mitre scale (22).

4.Retighten the mitre lock (25).

WARNING. Be sure to tighten the mitre lock before making a cut. Failure to do so could result in the table moving during the cut, causing serious personal injury.

5.Loosen the bevel lock (16) and pull out the 0º bevel adjuster (18) and move the saw arm (5) to the left or right to the desired bevel angle (between 0º and 45º). Tighten the bevel lock (16).

6.Place the workpiece flat on the table with one edge securely against the fence (19). If the board is warped, place the convex side against the fence. If the concave side is placed against the fence, the board could break and jam the blade.

7.When cutting long pieces of timber, support the opposite end of the timber with the side bars (37), a roller stand or a work surface that is level with the saw table.

8.Use the clamp assembly (10) to secure the workpiece wherever possible.

9.It is possible to remove the clamp assembly (10) by loosening the clamp assembly lock (11) and moving it to the other side of the table. Make sure the clamp

assembly lock is tight before using the clamp.

10.Before turning on the saw, perform a dry run of the cutting operation to check that there are no problems.

11.Hold the operating handle (7) firmly and squeeze the switch trigger (24). Allow the blade to reach maximum speed.

12.Press the release latch (36) and slowly lower the blade into and through the workpiece.

13.Release the switch trigger (24) and allow the saw blade to stop rotating before raising the blade out of the workpiece. Wait until the blade stops before removing the workpiece.

Adjusting the laser lines

The lower laser is factory set to emit a laser line along the right-hand side of the blade. The upper laser is factory set to emit a laser line to the left-hand side of the blade. This upper laser can be adjusted by the operator to suit blades of different kerf widths.

To adjust the position of the upper laser, proceed as follows:

1. Remove the laser cover by w pulling it towards you.

2.Switch on the laser lights with the on/off switch (2) (fig. w).

3.Using a Phillips head screwdriver (not supplied), adjust the position of the line from the upper laser

by turning the laser pitch

x

control (4) (fig. x).

 

4.Adjust until the left-hand laser line is aligned with the left-hand side of the blade.

5.Switch off the laser lights.
