5. HEALTH AND SAFETY INFORMATION
Wait for the machine to stop. Unless the machine is fitted with a safety brake, some parts may
continue to move due to momentum. Wait for all parts to stop, then unplug it from the power supply
before making any adjustments, carrying out maintenance operations or just finishing using the tool.
Remove and check setting tools. Some machinery requires the use of additional tools or keys to set,
load or adjust the power tool. Before starting the power tool always check to make certain they have
been removed and are safely away from the machine.
Prevent unintentional starting. Before plugging any machine in to the power supply, make sure the
switch is in the OFF position. If the machine is portable, do not hold the machine near the switch and
take care when putting the machine down, that nothing can operate the switch.
Carefully select an extension lead. Some machines are not suitable for use with extension leads. If
the tool is designed for use outdoors, use an extension lead also suitable for that environment. When
using an extended lead, select one capable of handling the current (amps) drawn by the machine in
use. Fully extend the lead regardless of the distance between the power supply and the tool. Excess
current (amps) and a coiled extension lead will both cause the cable to heat up and can result in fire.
Concentrate and stay alert. Distractions are likely to cause an accident. Never operate a power tool if
you are under the influence of drugs (prescription or otherwise), including alcohol or if you are feeling
tired. Being disorientated will result in an accident.
Have this tool repaired by a qualified person. This tool is designed to conform to the relevant
international and local standards and as such should be maintained and repaired by someone
qualified, using only original parts supplied by the manufacturer. This will ensure the tool remains safe
to use.
5.2 ADDITIONAL SAFETY INSTRUCTIONS FOR ALL SAWS
Keep hands away from cutting area and the blade. Keep your second hand on the auxiliary handle,
or motor housing. If both hands are holding the saw, they cannot be cut by the blade.
Do not reach underneath the workpiece. The guard cannot protect you from the blade below the
workpiece.
Adjust the cutting depth to the thickness of the workpiece. Less than a full tooth of the blade teeth
should be visible below the workpiece.
Never hold piece being cut in your hands or across your leg. Secure the workpiece to a stable
platform. It is important to support the work properly to minimise body exposure, blade binding or loss
of control.
Hold power tool by insulated gripping surfaces when performing an operation where the
cutting tool may contact hidden wiring or its own cord. Contact with a “live” wire will also make
exposed metal parts of the power tool “live” and shock the operator.
When ripping always use a rip fence or straight edge guide. This improves the accuracy of cut and
reduces chance of blade binding.
Always use blade with correct size and shape (diamond versus round) of arbour holes. Blades
that do not match the mounting hardware of the saw will run eccentrically, causing loss of control.
Never use damaged or incorrect blade washers or bolt. The blade washers and bolt were specially
designed for your saw, for optimum performance and safety of operation.
Causes and operator prevention of kickback:
– Kickback is a sudden reaction to a pinched, bound or misaligned saw blade, causing an
uncontrolled saw to lift up and out of the workpiece towards the operator.
– When the blade is pinched or bound tightly by the kerf closing down, the blade stalls and the motor
reaction drives the unit rapidly back towards the operator.
– If the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the blade can
dig into the top surface of the wood causing the blade to climb out of the kerf and jump back toward
the operator.

9. BASIC CIRCULAR SAW OPERATIONS
9.1 ON/OFF TRIGGER SWITCH – FIG.4
The trigger switch
(16)
is operated in conjunction with
a safety release button
(15)
so that it is not possible
to start the circular saw by accident.
– To start the saw, press the safety button
(15)
first
and then depress the trigger switch
(16)
.
● Always wear ear defenders during use.
9.2 DUST EXTRACTION – FIG.5
Inhalation of dust particles can be detrimental to
health. The dust outlet
(1)
must be connected with a
dust extraction machine.
Note: Due to the outlet diameter, a size adaptation
may be necessary.
Warning! All wood dust (including dust from
composites like chipboards and fibre boards etc.) is
hazardous to health. It can affect the nose, the
respiratory system and the skin. For example MDF
(medium density fibreboard) which contains
formaldehyde is a known carcinogen. In addition to
the above measures a correctly fitted dust mask,
suitable for the activity and in accordance to the
relevant standard, must be worn.
9.3 CUTTING DEPTH ADJUSTMENT –
FIG.6
– To adjust the cutting depth, loosen the cutting
depth adjustment knob
(12)
.
– Set the required cutting depth, using the depth
scale markings as a guide.
Note: For greater accuracy measure the tip of the
blade back to the base.
– Re-tighten the cutting depth adjustment knob
(12)
when the required depth is set.
9.4 CUTTING ANGLE ADJUSTMENT –
FIG.7
To alter the angle between 0° to 45°, loosen the bevel
angle locking knob
(8)
.
Note: The scale is a guide. If more accuracy is
required a protractor should be used off the underside
of the base against the blade.
– When the required angle is set, re-tighten the
bevel angle locking knob
(8)
.

9.5 PARALLEL GUIDE – FIG.8
– Pass the parallel guide
(6)
through the slots in the
base and secure with locking knob
(7)
.
– Set the required cutting width, using the width scale
markings as a guide.
– Make a test cut on a scrap piece of timber prior to
making any cuts on the workpiece and adjust
accordingly.
– For greater accuracy, measure between the edge of
the blade allowing for the kerf of the blade and the
parallel guide's face.
9.6 LASER GUIDE – FIG.9
Warning! Laser radiation. Do not stare into
beam. Class 2 laser product.
The laser beam aperture
(10)
is
activated by pressing button
(9)
and
will stay on until the button is pressed
again.
– Mark the line of the cut on the
workpiece.
– Adjust the depth and/or bevel angles
of the cut as required.
– Turn on the laser guide by pressing the laser on/off
button
(9)
and align the line of the cut on the
workpiece.
– When the blade is at its maximum speed (approx. 2
sec.) make the cut.
– On completion of the cut, switch off the laser.
9.7 SAW OPERATION
Caution: When using, always cut forward in a straight
line without forcing the saw. Forcing or twisting the saw
will put a strain on the motor, and at the very least result
in decreased efficiency or possible overheating
damage. More seriously, it could cause dangerous
kickback of the saw resulting in severe injury.
– Always operate the saw firmly, using the rear and
auxiliary handles.
– Offer the base of the saw to the workpiece without
blade contact.
– Switch on and wait until full speed is attained, then
advance the saw, keeping it flat and cutting
smoothly until the cut is complete – Straight line
sawing at a uniform speed of advance will obtain
the best clean cuts.
– After releasing the trigger switch, wait until the blade
has fully stopped before withdrawing.
5. HEALTH AND SAFETY INFORMATION
5.1 GENERAL SAFETY INSTRUCTIONS FOR POWER TOOL USE
When using any type of power tool there are steps that should be taken to make sure that you, as the
user, remain safe.
Common sense and a respect for the tool will help reduce the risk of injury.
Read the instruction manual fully. Do not attempt any operation until you have read and understood
this manual.
Most important you must know how to safely start and stop this machine, especially in an emergency.
Keep the work area tidy and clean. Attempting to clear clutter from around the machine during use
will reduce your concentration. Mess on the floor creates a trip hazard. Any liquid spilt on the floor
could result in you slipping.
Find a suitable location. If the machine is bench mounted, the location should provide good natural
light or artificial lighting as a replacement. Avoid damp and dust locations as it will have a negative
effect on the machine’s performance. If the machine is portable do not expose the tool to rain. In all
cases do not operate power tools near any flammable materials.
Keep bystanders away. Children, onlookers and passers by must be restricted from entering the work
area for their own protection. The barrier must extend a suitable distance from the tool user.
Unplug and house all power tools that are not in use. A power tool should never be left unattended
while connected to the power supply. They must be housed in a suitable location, away locked up and
from children. This includes battery chargers.
Do not overload or misuse the tool. All tools are designed for a purpose and are limited to what they
are capable of doing. Do not attempt to use a power tool (or adapt it in any way) for an application it is
not designed for. Select a tool appropriate for the size of the job. Overloading a tool will result in tool
failure and user injury. This covers the use of accessories.
Dress properly. Loose clothing, long hair and jewellery are all dangerous because they can become
entangled in moving machinery. This can also result in parts of body being pulled into the machine.
Clothing should be close fitted, with any long hair tired back and jewellery and neck ties removed.
Footwear must be fully enclosed and have a non-slip sole.
Wear personal protective equipment (PPE). Dust, noise, vibration and swarf can all be dangerous if
not suitably protected against. If the work involving the power tool creates dust or fumes wear a dust
mask. Vibration to the hand, caused by operating some tools for longer periods must be protected
against. Wear vibration reducing gloves and allow long breaks between uses. Protect against dust and
swarf by wearing approved safety goggles or a face shield. These are some of the more common
hazards and preventions, however, always find out what hazards are associated with the
machine/work process and wear the most suitable protective equipment available.
Do not breathe contaminated air. If the work creates dust or fumes connect the machine (if possible)
to an extraction system either locally or remotely. Working outdoors can also help if possible.
Move the machine as instructed. If the machine is hand held, do not carry it by the power supply
cable. If the product is heavy, employ a second or third person to help move it safely or use a
mechanical device. Always refer to the instructions for the correct method.
Do not overreach. Extending your body too far can result in a loss of balance and you falling. This
could be from a height or onto a machine and will result in injury.
Maintain your tools correctly. A well maintained tool will do the job safely. Replace any damaged or
missing parts immediately with original parts from the manufacturer. As applicable, keep blades sharp,
moving parts clean, oiled or greased, handles clean, and emergency devices working.
