Unpacking Your Tool
Carefully unpack and inspect your tool. Familiarise yourself with all its features and
functions.
Ensure that all parts of the tool are present and in good condition. If any parts are missing
or damaged, have such parts replaced before attempting to use this tool.
Operating Instructions
Dust extraction
• For a cleaner, safer work environment connect a dust extraction system or workshop
vacuum cleaner to the Dust Extraction Port (1)
Notes:
• Before you use your saw, it is recommended that you practice on scrap material. The
settings of the machine are crucial to achieving a good quality finish, and your work
could easily be damaged by using an incorrect setting
• The supplied blade comes pre-fitted. Make sure the Blade Securing Bolt (5) is securely
tightened before first use
WARNING: Always disconnect the saw from the power supply before fitting or removing
any accessory.
Fitting and removing blades
• Always check the blade being fitted is suitable for the material you intend to cut
• Only fit blades that are in perfect condition. Blunt, bent, and cracked blades should be
discarded
1. Hold the Blade Flange in position using the Pin Spanner (20). Unscrew the Blade
Securing Bolt (5) anti-clockwise using the Spanner (21)
2. Remove the blade securing bolt, washer and blade flange. A saw blade can now be
fitted or removed
3. Use the Guard Retraction Lever (10) to rotate the guard out of the way
4. Fit the required blade, making sure the direction indicator on the face of the blade is
in the same direction as the Blade Direction Indicator (2)
5. Re-fit the blade flange, washer and blade securing bolt, and tighten using the pin
spanner and spanner
6. Ensure the blade is secure before use
Setting bevel angle
• This saw is equipped with a tilting Base Plate (7). This allows bevel cuts to be made
• To alter the angle of the base plate, loosen the Bevel Angle Locking Screw (3) and the
Bevel Locking Screw (14). The base plate will now be free to pivot
• Select the angle required (0-45°) using the angle scale next to the bevel angle locking
screw and re-tighten both bevel screws
• To ensure accuracy, the angle between the blade and the base plate should be checked
using a suitable protractor
Setting depth adjustment
• This saw is equipped with a depth adjustment mechanism
• To alter the depth of the cut, loosen the Depth Locking Screw (15). The base plate is
now free to adjust to the required depth
• Adjust the base plate to the required depth using the depth scale or a ruler and retighten
the depth locking screw
• When set correctly, the blade teeth should project approximately 3mm from the
underside of the material being cut
Handling your circular saw
• Always hold the saw securely, with both hands, by the handles provided
• Always allow the blade to come to a complete stop before placing the machine down
• Always unplug the machine if it is to be left unattended
• Always make sure that work will not move whilst being cut. Use clamps where
appropriate
Making a cut
1. Hold the saw securely and rest the front edge of the Base Plate (7) on the edge of the
work piece
2. Check that the blade is not in contact with the work piece, or any other object
3. Start the machine by pressing in the Lock Off Button (18) and squeezing the On/Off
Trigger (17)
4. Allow the motor to reach full speed, and push the saw smoothly forwards across the
workpiece
5. Maintain a steady movement and ensure the base plate is kept pressed against the
work
NOTE: The front edge of the base plate features a guide notch. For normal cutting align
the notch marked ‘0˚’ with the intended cutting line; for 45˚ bevel cutting align the notch
marked ‘45˚’ with the cutting line.
6. Allow the blade to pass through the material and release the trigger switch.
Alternatively, if the cut does not reach the edge of the workpiece, release the trigger
switch and allow the blade to stop moving before lifting out of the cut
7. Do not place the machine down until the blade has stopped completely
Using the parallel guide fence
1. When working parallel to an edge, the Parallel Guide Fence (8) should be used
2. The guide fence attaches to the Base Plate (7), and is secured using the Guide
Locking Screw (6). Ensure the guide fence is attached securely
3. The position of the guide fence can be adjusted to suit different tasks
4. To follow an edge, keep the vertical foot of the guide fence pressed against the
vertical edge as the cut is made
Riving knife
• This power tool has a fitted Riving Knife (13) which is a small blade situated behind the
saw blade. This is an important safety device which helps prevent kickbacks during use
• The thickness of the riving knife (A) should fall between the thickness of the kerf (B) and
the thickness of the blade body (C), see Fig. A.
• The supplied blade has a kerf of 2.5mm and a blade body thickness of 1.4mm. The
riving knife is 1.7mm. When replacing blades ensure the blade body thickness is below
1.7mm and the kerf is above 1.7mm when using the supplied riving knife
• Minor adjustment of the riving knife position can be achieved by loosening the Riving
Knife Bolts (11), re-positioning and then re-tightening
• In some instances the riving knife may need to be re-flattened, replaced or temporarily
removed, in which case the riving knife bolts should be fully removed before sliding the
riving knife out
• Replace immediately if the riving knife becomes damaged or cannot be made flat
• Position the riving knife so it is centralised behind the saw blade. The riving blade
bolts may require additional washers to centralise the riving knife when using different
thickness saw blades
• The riving knife can be removed for plunge cuts. Plunge cuts needs special care and
attention. Take time to prepare and make sure all safety precautions are followed
WARNING: Always re-fit the riving knife. It is an essential safety feature for normal use.
