Before Use

Dust extraction
• For a cleaner, safer work environment, and to protect the tool from dust and over-heating,
connect a dust extraction system or workshop vacuum cleaner to the Dust Extraction Port
(9) and ensure the Motor Vents (27) are kept free of wood chippings and dust. Regularly
clean the area of the tool with a vacuum when a dust extraction system cannot be fitted
or used
Notes:
• The supplied blade is pre-fitted; make sure the Blade Securing Bolt (13) is securely
tightened before first use
Removing a battery
• Remove the Battery (6) from the tool by pressing the Battery Release (5), then slide the
Battery out of the Battery Slot (7)
WARNING: DO NOT try to remove the Battery without pressing the Battery Release button.
The tool or Battery could be damaged.
Fitting a battery
1. Fit a battery by sliding it on to the Battery Slot (7) of the tool until it clicks and locks into
position
Note: Make sure the Battery and tool are lined up correctly. If the Battery does not slide into
the tool easily, do not force it. Instead, slide the Battery out of the tool again, check the top of
Battery and the tool battery slot are clean and undamaged and that the contacts are not bent.
Setting up the battery charger
1. If fitted, remove any Battery from the Battery Charger (30)
2. Insert the Battery Charger mains plug into a suitable mains socket
Note: The Green LED (31) on the Battery Charger will flash to indicate that the charger is
ready to charge the battery.
WARNING: Use this charger ONLY to charge the supplied battery or additional purchased
batteries that are specifically designed for this tool.
WARNING: The charger is designed for indoor use only, and MUST NOT be used in damp
or wet conditions.
Charging the battery
WARNING: Failure to follow the correct procedure when charging batteries will result in
permanent damage.
Note: Normal charging time is approximately 80 minutes for a recently discharged 4.0Ah
capacity battery. However, if the Battery (6) has been left in a discharged state for some time,
it may take additional time to charge.
1. Slide a fully or partially discharged Battery on to the Battery Charger (30)
Note: Make sure the Battery and Battery Charger are lined up correctly. If the Battery does
not slide on to the Battery Charger easily, don't force it. Instead, remove the Battery, check
the top of Battery and the Battery Charger slot are clean and undamaged and that the
contacts are not bent.
2. Once charging commences, the Red LED (29) will illuminate
3. When the Battery is fully charged, the Green LED (31) will illuminate
Battery Charge Level: The Battery has a built-in Battery Charge Indicator (10) (Fig. I).
Pressing on the button to the right will indicate the charge level. The right LED indicates a
high charge level and the left a low charge level that will mean the battery pack will require
charging soon.
IMPORTANT: When a low charge level is indicated, the tool may stop operating while in use,
which is dangerous when operating a circular saw. Always ensure the battery pack has a
good charge level.
Note: It is highly recommended to only use 3.0Ah and 4.0Ah batteries with this tool due to
the high current motor and safety issues with the battery fully discharging in use stopping the
tool operating.

Notes about battery charging:
• The battery should be charged at ambient temperatures between 10 and 40°C (ideally
around 20°C)
• After charging, allow 15 minutes for the battery to cool before use
• Ensure that the charger is disconnected from the mains supply after use, and is stored
correctly
• DO NOT leave batteries on charge for extended periods and NEVER store batteries on
charge
• The Battery Charger monitors battery temperature and voltage while charging. Remove
the Battery once charging is complete to maximise charge cycles of the battery and not
waste power
• Batteries can become faulty over time, individual cells in the battery can fail and the
battery could short. The charger will not charge faulty batteries. Use another battery, if
possible, to check correct functionality of the charger and purchase a replacement battery
if a faulty battery is indicated
• DO NOT store lithium-ion battery packs in a discharged state over a long period as this
can damage the lithium-ion cells. For long-term storage, store batteries in a high charge
state disconnected from the power tool
• The capacity of batteries will reduce over time. After 100 charge cycles, the battery's
operation time and the maximum torque performance of the driver will slightly reduce. This
decline will continue until the battery has minimal capacity after 500 charge cycles. This is
normal and not a fault with the battery pack
Fitting and removing blades
WARNING: Remove battery pack if fitted.
WARNING: Wear cut-proof gloves when handling sharp blades.
• Always check the blade being fitted is suitable for the material being cut
• Only fit blades that are in perfect condition. Blunt, bent, and cracked blades should be
discarded
1. Press in the Spindle Lock Button (28) and carefully rotate the blade by pushing on the side
face of the saw blade until the spindle lock engages. Unscrew the Blade Securing Bolt (13)
anti-clockwise using the supplied hex key
2. Remove the Blade Securing Bolt, washer (if fitted) and Blade Flange (15).
3. Use the Lower Guard Lever (12) to rotate the Lower 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 Direction Indicator (26)
5. Re-fit the Blade Flange, washer and Blade Securing Bolt. Press in the Spindle Lock Button
and tighten using the hex key
6. Ensure the blade is secure before use
Setting bevel angle
• This saw is equipped with a tilting Base Plate (14). This allows bevel cuts to be made
• Alter the angle of the Base Plate by loosening the Bevel Angle Locking Knob (22). The
Base Plate will now be free to pivot
• Select the angle required (0-45°) using the Bevel Angle Gauge (25) and retighten the
Bevel Angle Locking Knob
• Ensure accuracy by checking the angle between the Blade (11) and the Base Plate using
a suitable protractor
Setting depth adjustment
• This saw is equipped with a depth adjustment mechanism
• Alter the depth of the cut by loosening the Depth Locking Knob (23). The Base Plate (14)
is now free to adjust to the required depth
• Adjust the Base Plate to the required depth using the Depth Scale (24) or a ruler and
retighten the Depth Locking Knob
• When set correctly, the blade teeth should project approximately 3mm from the underside
of the material being cut
