Frequently Asked Questions - AHS 66/2 Alpha Tools

How to adjust the cutting depth?

Loosen the locking lever on the back of the guard (4), place the saw foot on the workpiece, raise the saw to the desired depth, then tighten the lever. Check that it holds correctly.

How to change the saw blade?

Disconnect the appliance. Push back the protective guard (19) and hold it with the lever (15). Lock the flange (18) with the blade key, loosen the screw (17) with the hex key, remove the flange and the blade. Clean the flange, mount the new blade respecting the rotation direction, then tighten the screw.

What safety equipment should I wear?

Wear hearing protection, a dust mask and safety goggles. Noise can damage hearing, dust is harmful to lungs, and sparks or splinters can injure eyes.

How to use the parallel guide?

Loosen the fixing screw (8) in the saw foot, insert the parallel guide (16) into the slide, set the desired distance, then tighten the screw. Position the guide against the workpiece edge and start sawing.

How to connect a vacuum cleaner?

Connect the vacuum cleaner to the chip extraction connector (14) at the front of the saw. Ensure the vacuum cleaner is suitable for the material being processed and that the connection is secure. This improves dust extraction.

5.1 Setting the cutting depth (Figure 2/3)

• Release the handle on the rear of the guard hood for adjusting the cutting depth (4).
• Place the saw foot (6) flat on the surface of the workpiece you wish to saw. Raise the saw until the saw blade (12) is at the required cutting depth (a).
• Refasten the handle for adjusting the cutting depth (4). Check the handle is securely fastened.

GBGBR

5.2 Miter stop (Figure 4/5)

• The preset standard angle between the saw foot (6) and saw blade (12) is 90°. You can adjust this angle to carry out angled cuts.
• Release the locking lever for miter setting (7) on the front of the saw foot.
• You can now adjust the cutting angle to around 45°. Keep an eye on the cutting angle scale (9) as you do so.
• Refasten the locking lever for miter setting (7). Check the handle is securely fastened.

5.3 Extraction of dust and chips (Figure 6)

• Connect a suitable vacuum cleaner (a) to the provided chip extractor connector (14) of your circular saw (vacuum cleaner not included). This will provide excellent dust extraction on the workpiece. The benefits are that you will protect both the equipment and your own health. Your work area will also be cleaner and safer.
• Dust created when working may be dangerous. Refer to the section entitled “Safety instructions”.
• Important! The vacuum cleaner you use for the extraction work must be suitable for the workpiece material.
• Check that all the parts are properly connected.

5.4 Parallel stop (Figure 7/8)

• The parallel stop (16) enables you to saw parallel lines.
• Loosen the locking screw for the parallel stop (8) on the saw foot (6).
• To assemble, slide the parallel stop (16) into the guide (a) on the saw foot (6) (see Figure 7)
• Set the required spacing and then tighten the locking screw (8) again.
• Using the parallel stop: Position the parallel stop (16) flat on the edge of the workpiece and start the cut.

⚠️ Important! Carry out a trial cut in a piece of waste wood

6. Operation

6.1 Working with the hand-held circular saw

• Always hold the circular saw firmly.
- The swing guard hood (19) is pushed back automatically by the workpiece.
- Do not use force! Push forwards gently and evenly with the circular saw.
- The waste piece should be on the right-hand side of the circular saw so that the wide section of the support bench supports its full area.
- If you are sawing down a line that has been drawn, guide the circular saw along the corresponding notch.
- Clamp small pieces of wood securely before sawing them. Never hold them with your hand.
• Always follow the safety instructions. Wear safety goggles.
- Do not use defective saw blades or blades that are cracked or broken.
- Do not use any flanges / flange nuts whose bore hole is larger or smaller than those in the saw blade.
- The saw blade must not be decelerated by hand or by applying lateral pressure to the blade.
- The swing guard hood must not jam and must return to its initial position after the operation has been completed.
- Before you use the circular saw, check the function of the swing guard hood with the mains plug disconnected.
- Before you use the machine, ensure that the safety equipment such as the swing guard hood, splitter, flanges and adjustment devices are in working order and are correctly adjusted and secure.
- You can connect a suitable dust extraction system to the sawdust extraction connector (14). Ensure that the dust extractor line is safely and correctly connected.
- The moving swing guard hood must not be fixed in the retracted guard hood when the saw is in use.
- Saw blades whose main body is thicker or tooth set thinner than the thickness of the splitter must not be used.

⚠️ Important. Always pull out the power plug before doing any work on the circular saw!

GBGBR

6.2 Using the circular saw

• Adjust the cutting depth, cutting angle and parallel stop (see section 5.1, 5.2 and 5.4)
• Ensure that the ON/OFF switch (2) is not depressed. Only then should you connect the mains plug to a suitable socket.
• Do not switch on the circular saw until you have fitted a saw blade.
• Place the saw foot flat on the workpiece you wish to saw. The saw blade must not be in contact with the workpiece.
• Hold the circular saw firmly with both hands.

6.3 Switching ON/OFF (Fig. 9)

To switch on:

Press the locking button (3) and the ON/OFF switch (2) at the same time

- Allow the saw blade to accelerate until it reaches full speed. Then slowly move the saw blade along the cutting line. Only exert gentle pressure on the saw blade as you do so.

To switch off:

Release the locking button and ON/OFF switch

• If you release the handle the equipment will shut down automatically which means that it cannot operate accidentally.
• Ensure that you do not cover or block the ventilation openings whilst working with the tool.
• Do not slow down the saw blade after you switch it off by pressing it sideways.
• Important! Do not put down the machine until the saw blade has reached a complete standstill.

⚠️ Important. Carry out a trial cut in a piece of waste wood

6.4 Changing the saw blade (Fig. 10-11)

⚠️ Important. Always pull out the power plug before doing any work on the circular saw!

Only use saw blades of the same type as the saw blade supplied with this circular saw. Ask your dealer for advice.

• Push back and secure the moving swing guard hood (19) using the lever for the swing guard hood (15).
• Use the saw blade wrench (13) to apply counterpressure to the flange (18).

• Undo the screw to secure the saw blade (17) using the Allen key (a).

• Remove the flange (18) and the saw blade (12) in a downwards direction.

• Clean the flange and insert the new saw blade. Pay attention to the running direction (see arrow on the guard hood and saw blade).
• Tighten the screw to secure the saw blade (17), check it runs true.
• Before you press the On/Off switch, make sure that the saw blade is correctly fitted and that moving parts run smoothly and the clamping screws are tightened securely.
