more than half full. This allows better air flow through the bag.

5. SETTING THE TABLE SQUARE WITH THE BLADE

Make sure that the electrical plug is removed from the power point

6

Push the saw arm (5) down to its lowest position and engage the release knob (6) to hold the saw arm in the transport position.

7

Loosen the mitre lock (25).

8

Rotate the table (21) until the pointer is positioned at 0 º .

9

Tighten the mitre lock (25).

10

Loosen the bevel lock (16) and set the saw arm (5) at 0 º bevel (the blade at 90 º to the mitre table). Tighten the bevel lock (16).

11

Place a set square against the table (21) and the flat part of the blade.

NOTE.

Make sure that the square contacts the flat part of the saw blade, not the teeth.

Rotate the blade by hand and check the blade-to-table alignment at several points.

The edge of the set square and the saw blade should be parallel.

12

If the saw blade angles away from the set square, adjust as follows:

•

Use a 13mm wrench or adjustable wrench to loosen the lock nut securing the 0 ° bevel adjustment screw (34).

Also, loosen the bevel lock (16).

• Adjust the 0 ° bevel adjustment screw (34) with the wrench to bring the saw blade into alignment with the square.

•

Loosen the screw holding the pointer of the bevel scale (17) and adjust the position of the pointer so that it accurately indicates zero on the scale. Retighten the screw.

•

Retighten the bevel lock (16) and the lock nut securing the 0 ° bevel adjustment screw (34).

13

NOTE. The above procedure can also be used to check the angle of the saw blade to the table at 45 º bevel

8

angle. The 45 ° bevel adjustment screw (33) is on the opposite side of the saw arm.

14. ADJUSTING THE LASER LINES

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

15 TRENCH DEPTH ADJUSTMENT

In its normal position, the trenching stop (31) permits the saw blade to cut right through a workpiece.

When the saw arm is lifted, the trenching stop can be adjusted so that the trenching depth adjustment screw (30) contacts the stop as the saw arm is lowered.

This restricts the cut to a “ trench ” in the workpiece. The depth of the trench can be adjusted with the trenching depth adjustment screw (30) and locked in position with the trenching depth lock nut (32).

16 SIDE SUPPORT BARS

The side support bars (36) can be used to support long pieces of timber.

There are two location holes (37) for a support bar on either side of the table.

Ensure that the side bars are fully inserted before using them to support the workpiece.

V-Operation

WARNINGS.

- Do not stare directly at the laser beam. Never aim the beam at any person or an object other than the workpiece.

- Do not deliberately aim the beam at personnel and ensure that it is not directed towards the eye of a person for longer than 0.25s.

- Always ensure the laser beam is aimed at a sturdy workpiece without reflective surfaces. Wood or rough coated surfaces are acceptable. Bright shiny reflective surfaces are not suitable for laser use as the reflective surface could direct the beam back at the operator.

- Always remember to switch off the laser on/off switch (2) after finishing a job. Only turn the laser beam on when the workpiece is on the mitre saw table.

- Mark the line of the cut on the workpiece.

- Adjust the angle of mitre and bevel of the cut as required.

With the saw arm (5) in the raised position, use a soft brush to dust away the sawdust build-up around the assembly.

NOTE. Wear eye and respiratory protection whilst brushing the dust away.

2 CROSS-CUTTING (WITHOUT SLIDE ACTION)

When cutting a narrow piece of wood it is not necessary to use the slide mechanism. In these cases ensure that the slide lock (29) is screwed down to prevent the saw arm from sliding.

1)

A crosscut is made by cutting across the grain of the workpiece. A 90 º crosscut is made with the mitre table set at 0 º . Mitre crosscuts are made with the table set at some angle other than zero.

Pull on the release knob (6) and lift the saw arm (5) to its full height.

2)

Loosen the mitre lock (25).

Rotate the mitre table (21) until the pointer aligns with the desired angle.

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 and cause serious personal injury.

Place the workpiece flat on the table with one edge securely against the fence (18). If the board is warped, place the convex side against the fence (18). If the concave side is placed against the fence, the board could break and jam the blade.

10

3)

When cutting long pieces of timber, support the opposite end of the timber with the side support bars (36), a roller stand or a work surface that is level with the saw table.

4)

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

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.

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

Press the release latch (35) and slowly lower the blade into and through the workpiece.

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.

3 CROSS-CUTTING (WITH SLIDE ACTION)

When cutting wide workpieces, first unscrew the slide lock (29).

Pull on the release knob (6), raise the saw arm (5) to its highest position and slide it towards you.

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

Press the release latch (35) and slowly lower the blade into the workpiece and slide it away from you at the same time until the workpiece is cut.

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.

4 BEVEL CUT

A bevel cut is made by cutting across the grain of the workpiece with the blade angled to the fence and mitre table.

The mitre table is set at the zero degree position and the blade set at an angle between 0 º and 45 º .

Use the slide action when cutting wide workpieces.

Repeat Steps 29 and 30.

Loosen the bevel lock (16) and move the saw arm (5) to the left to the desired bevel angle (between 0 º and 45 º ).

Tighten the bevel lock (16).

Repeat Steps 31 and 32.

5 COMPOUND MITRE CUT

A compound mitre cut involves using a mitre angle and a bevel angle at the same time.

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.

VI - Maintenance and repair

DANGER.

- Never try to use a blade larger than the stated capacity of the saw. It might come into contact with the blade guards.

- Never use a blade that is too thick to allow the outer blade washer to engage with the flats on the spindle. It will prevent the blade screw from properly securing the blade on the spindle.

- Do not use the saw to cut metal or masonry.
