Clamping the Workpiece (Fig. U–W, BB)

WARNING: A workpiece that is clamped, balanced and secure before a cut may become
unbalanced after a cut is completed. An unbalanced load may tip the saw or anything the
saw is attached to, such as a table or workbench. When making a cut that may become
unbalanced, properly support the workpiece and ensure the saw is firmly bolted to a
stable surface. Personal injury may occur.

WARNING: The clamp foot must remain clamped above the base of the saw whenever
the clamp is used. Always clamp the workpiece to the base of the saw – not to any other
part of the work area. Ensure the clamp foot is not clamped on the edge of the base of
the saw.

CAUTION: Always use a workpiece clamp to maintain control and reduce the risk of
personal injury and workpiece damage.
34
Use the workpiece clamp provided with your saw. Other aids such as spring clamps, bar
clamps or C-clamps may be appropriate for certain sizes and shapes of material. The left side
fence will slide from side to side to aid in securing.
To install Clamp
1. Insert the workpiece clamp into the hole lateral to the mitre fence.
2. Rotate the clamp arm toward to the front of the mitre saw.
3. Loosen the knob to adjust the clamp up and down and secure it in the choosen height.
4. Use the fine adjust knob to firmly clamp the workpiece.
nOTE: Place the clamp on the right 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.

General Handling

• In the mitre saw mode, the sawhead is automatically locked in the upper "park" position.
• Squeezing the guard release lever will unlock the sawhead. Moving the sawhead down
retracts the moveable lower guard.
• Never seek to prevent the lower guard returning to its park position when the cut
is completed.
• The minimum length of offcut material is 10 mm.
• When cutting UPVC sections, a supporting piece made out of timber with a
complementary profile should be placed beneath the material being cut to provide the
correct level of support.
Vertical Straight Cross Cut (Fig. U)
1. Set the rotating table to 0° and make sure that the locating plunger is engaged.
2. Tighten the rotating table clamping knob.
3. Place the wood to be cut against the fence. Take hold of the control handle and press in
the guard retraction lever.
4. Switch the machine on.
5. Allow the blade to cut freely. Do not force.
6. After completing the cut, release the switch and wait for the saw blade to come to a
complete standstill before returning the head to its upper rest position.
7. Release the guard retraction lever.

WARNING: Do not allow the sawhead to jump back unaided to prevent damage.
Mitre Cuts (Fig. V)
1. Set the required mitre angle.
2. Ensure that the rotating table clamp is tightly secured.
3. Proceed as for a vertical straight cross-cut.
4. Prevent the blade cutting the table if the angle is not 45°.

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: left mitre, off-cut to the right mitre, off-cut to the left.
Bevel Cuts (Fig. A, W)
24
1. Release the bevel clamp knob and tilt the head to the angle required.
2. Tighten the bevel clamp handle.
3. Proceed as for a vertical straight cross-cut.

Compound Mitre

This cut is a combination of a mitre and a bevel cut. The limitations are 35° mitre/30° bevel. Do
not exceed these limits.
Set the bevel angle and subsequently set the mitre angle.
Sawing in the Bench Mode
• Always use the riving knife.
• Always ensure that the riving knife and blade guard are correctly aligned.
• Always ensure that the mitre saw is set and locked in 0° mitre.

WARNING: DO NOT cut any type of metal material.
Ripping (Fig. A, X)
1. Set the bevel angle to 0°.
2. Adjust the saw blade height. The correct blade position is to have the tips of three teeth
above the top surface of the wood.
3. Set the parallel fence to the required distance.
4. Hold the workpiece flat on the table and against the fence. Keep the workpiece approx.
25 mm away from the saw blade.
14
5. Keep both hands away from the path of the saw blade.
6. Switch the machine on and allow the saw blade to reach full speed.
7. Slowly feed the workpiece underneath the upper blade guard, keeping it firmly pressed
against the fence. Allow the teeth to cut, and do not force the workpiece through the saw
blade. The saw blade speed should be kept constant.
8. Remember to use the push stick 19 when close to the blade.
9. After completing the cut, switch the machine off, allow the saw blade to stop and remove
the workpiece.

WARNING: Never push or hold the free or cut-off side of the workpiece.

WARNING: Always use a push stick when ripping small workpieces.
Bevel Cuts (Fig. Y)
1. Release the bevel clamp knob and set the blade to the required angle.
2. In order to prevent material jamming between the blade and the fence, position the fence
to the left of the blade.
3. Proceed as for vertical ripping.
Mitre Cuts (Fig. Z1–Z3)
1. To adjust the mitre fence, loosen the stop screw locknut
out until the mitre pointer reads 0° (Fig. Z1).
2. Set the blade height and angle.
73
3. Insert the slide bar of the mitre fence into the groove
side of the table (Fig. Z2).
75
4. Loosen the mitre locking knob and rotate the fence to set the scale to the required
angle (Fig. Z3).
5. Tighten the mitre locking knob 75 .
6. Place the workpiece against the flat surface of the mitre fence. Switch on and, holding the
workpiece firmly, slide the fence along the groove to take the workpiece into the blade.
When the cut is completed, switch off immediately.
Fence Positions, Bench Saw Mode (Fig. AA)
• For ripping thin materials, use the 11 mm profile of the dual height parallel fence and
position the fence opposite the front edge of the riving knife.
• For ripping thicker materials, use the 62 mm profile of the dual height parallel fence.
• For cross-cutting narrow and short workpieces (Fig. AA):
- Adjust the parallel fence with the low profile facing the blade and install the rear of the
fence in line with the leading edge of the blade.
- Set the workpiece against the mitre fence (at 0° or 90°) and push the mitre fence to
make the cut.
To prevent small offcut pieces fouling against the blade, prepare a tapered length of
-
timber and clamp it on the rear edge of the worktable close enough to the right-hand
side of the blade so that successive offcuts feed automatically to the right.
• For ripping narrow (< 120 mm) and long workpieces:
- Place the fence in rearmost position to maintain accuracy during long cuts.
- Push the workpiece with both hands (one on each side of the blade).
- Use a push stick when close to the blade.
- Support long workpieces at the outfeed side.
• For ripping wider (> 120 mm) workpieces:
- Adjust the fence forward as in figure W if the material being cut tends to jam between
the blade or the riving knife and the fence.
