Use the workpiece clamp provided with your saw. The left or right fence will slide from
53
side to side to aid in clamping. Other aids such as spring clamps, bar clamps or C-clamps may
be appropriate for certain sizes and shapes of material.
To Install Clamp
1. Insert it into the hole behind the fence. The clamp should be facing toward the back of the
mitre saw. The groove on the clamp rod should be fully inserted into the base. Ensure this
groove is fully inserted into the base of the mitre saw. If the groove is visible, the clamp will
not be secure.
2. Rotate the clamp 180° toward the front of the mitre saw.
3. Loosen the knob to adjust the clamp up or down, then use the fine adjust knob
firmly clamp the workpiece.
nOtE: Place the clamp on the opposite side of the base when beveling. ALWAYS MAKE DRY
RUNS (UNPOWERED) BEFORE FINISH CUTS TO CHECK THE PATH OF THE BLADE. ENSURE THE
CLAMP DOES NOT INTERFERE WITH THE ACTION OF THE SAW OR GUARDS.
Basic Saw Cuts
Vertical Straight Cross Cut (Fig. A, Y)
1. Release the mitre lock handle and depress the mitre latch button
4
2. Engage the mitre latch button at the 0° position and tighten the mitre lever.
3. Place the wood to be cut against the fence
4. Take hold of the operating handle 17
5. Depress the head to allow the blade to cut through the timber and enter the plastic kerf
plate .
28
6. After completing the cut, release the trigger switch and wait for the saw blade to come to
a complete standstill before returning the head to its upper rest position.
Performing a Sliding Cut (Fig. Z)
The guide rail allows cutting larger workpieces using an out-down-back sliding motion.
1. Release the rail lock knob 13 .
2. Pull the saw head towards you and switch the tool on.
3. Lower the saw blade into the workpiece and push the head back to complete the cut.
4. Proceed as described above.

WARNING: Remember to lock the saw head in the rear position when the sliding cuts
are finished.
Vertical Mitre Cross-Cut (Fig. A, AA)
1. Release the mitre lock handle 4 and depress the mitre latch button
or right to the required angle.
2. The mitre latch button will automatically locate at 10°, 15°, 22.5°, 31.62° and 45° both left
and right, and at 50° left and 60° right. If any intermediate angle is required hold the head
firmly and lock by tightening the mitre lever.
3. Always ensure that the mitre lock handle is locked tightly before cutting.
4. Proceed as for a vertical straight cross-cut.

WARNING: When mitring the end of a piece of wood with a small off-cut, position the
wood to ensure that the off-cut is to the side of the blade with the greater angle to the
fence; i.e. left mitre, off-cut to the right - right mitre, off-cut to the left.
Bevel Cuts (Fig. A, BB)
Bevel angles can be set from 48° left to 2° right and can be cut with the mitre arm set between
zero and a maximum of 45° mitre position right or left.
1. Loosen the left side fence clamping knob
fence 3 to the left as far as it will go. Loosen the bevel clamp handle
as desired.
2. Tighten the bevel clamp handle 11 firmly.
3. Proceed as for a vertical straight cross-cut.
Quality of Cut
The smoothness of any cut depends on a number of variables, e.g. the material being cut.
When smoothest cuts are desired for moulding and other precision work, a sharp (60 tooth
carbide) blade and a slower, even cutting rate will produce the desired results.

WARNING: Ensure that the material does not creep while cutting; clamp it securely
in place. Always let the blade come to a full stop before raising the arm. If small fibres
of wood still split out at the rear of the workpiece, stick a piece of masking tape on the
wood where the cut will be made. Saw through the tape and carefully remove tape
when finished.
Cutting Picture Frames, Shadow Boxes & Other Four Sided
Projects (Fig. CC, DD)
Trim Moulding and Other Frames
Try a few simple projects using scrap wood until you develop a "feel" for your saw. Your saw is
the perfect tool for mitring corners like the one shown in Figure CC. The joint shown has been
made using either bevel adjustment.
- Using bevel adjustment
The bevel for the two boards is adjusted to 45° each, producing a 90° corner. The mitre arm is
locked in the zero position. The wood is positioned with the broad flat side against the table
and the narrow edge against the fence.

. Press the trigger switch 1 to start the motor.
5 . Move the arm left
26 and slide the upper part of the left side
11 and set the bevel
- Using mitre adjustment
The same cut can be made by mitring right and left with the broad surface against the fence.
The two sketches (Fig. CC, DD) are for four side objects only. As the number of sides changes,
so do the mitre and bevel angles. The chart below gives the proper angles for a variety of
shapes, assuming that all sides are of equal length. For a shape that is not shown in the chart,
divide 180° by the number of sides to determine the mitre or bevel angle.

Compound Mitre (Fig. AA, BB, EE, FF)
A compound mitre is a cut made using a mitre angle (Fig. AA) and a bevel angle (Fig. BB) at the
same time. This is the type of cut used to make frames or boxes with slanting sides like the one
shown in Figure EE.

WARNING: If the cutting angle varies from cut to cut, check that the bevel clamp knob
and the mitre lock knob are securely tightened. These knobs must be tightened after
making any changes in bevel or mitre.
• The chart shown below will assist you in selecting the proper bevel and mitre settings
for common compound mitre cuts. To use the chart, select the desired angle "A" (Fig. FF)
of your project and locate that angle on the appropriate arc in the chart. From that point
follow the chart straight down to find the correct bevel angle and straight across to find
the correct mitre angle.

SET THIS BEVEL ANGLE ON SAW
• Set your saw to the prescribed angles and make a few trial cuts.
• Practice fitting the cut pieces together.
• Example: To make a 4 sided box with 25° exterior angles (angle "A") (Fig. FF), use the upper
right arc. Find 25° on the arc scale. Follow the horizontal intersecting line to either side to
get the mitre angle setting on the saw (23°).
Likewise follow the vertical intersecting line to the top or bottom to get the bevel angle
setting on the saw (40°). Always try cuts on a few scrap pieces of wood to verify the
settings on the saw.
Cutting Base Mouldings
The cutting of base moulding is performed at a 45° bevel angle.
• Always make a dry run without power before making any cuts.
• All cuts are made with the back of the moulding laying flat on the saw.
Inside Corner
Left side
• Position the moulding with top of the moulding against the fence.
• Save the left side of the cut.
Right side
• Position the moulding with the bottom of the moulding against the fence.
• Save the left side of the cut.
Outside Corner
Left side
• Position the moulding with the bottom of the moulding against the fence.
• Save the right side of the cut.
