Safety Rules for Laser Lights
The laser used in this device is a Class 2 laser with maximum power of
≤1mW and a wavelength of 650nm.
These lasers do not normally present an optical hazard, although staring at
the beam may cause flash blindness.
WARNING: Avoid direct eye contact.
A hazard may exist if you deliberately stare into the beam, please observe
all safety rules as follows:
• The laser shall be used and maintained in accordance with the
manufacturer’s instructions
• Do not switch on the laser light until the tool is ready to cut
• Never aim the beam at any person, and particularly not into the eyes of
any person or animal, or any object other than the workpiece
• Always ensure the laser beam is aimed at a sturdy workpiece without
reflective surfaces. i.e. wood or rough-coated surfaces are acceptable.
Reflective sheet steel or similar is not suitable for laser use as the
reflective surface could direct the beam back at the operator
• Do not change the laser light assembly. Repairs must only be carried
out by the laser manufacturer or an authorised agent. Do NOT
exchange with a different type of laser
CAUTION: Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation
exposure.
Please refer to the relevant EN standards, EN60825-1/A1:2002 for more
information on Lasers.
Circular Saw Safety
WARNING. Before connecting a tool to a power source (mains switch
power point receptacle, outlet, etc.) be sure that the voltage supply is the
same as that specified on the nameplate of the tool. A power source with a
voltage greater than that specified for the tool can result in serious injury to
the user, and damage to the tool. If in doubt, do not plug in the tool. Using
a power source with a voltage less than the nameplate rating is harmful to
the motor.
• Do not allow anyone under the age of 18 years to operate this saw
• When operating the saw, use safety equipment including safety goggles
or shield, ear protection, dust mask and protective clothing including
safety gloves
• Hand-held power tools may produce vibration. Vibration can cause
disease. Gloves may help to maintain good blood circulation in the
fingers. Hand-held tools should not be used for long periods without a
break
• Always use recommended blades with correct size and shape of arbor
holes e.g. diamond or round. Blades that do not match the mounting
hardware of the saw will run eccentrically, causing loss of control
• Whenever possible, use a vacuum dust extraction system to control
dust/waste
• Power tools must always be held by the insulated gripping surfaces
when performing an operation, ensuring protection if the cutting tool
makes contact with its own cord or hidden wiring. Contact with a ‘live’
wire will make exposed metal parts of the power tool ‘live’ and shock
the operator if the insulated gripping surfaces are not used
• Ensure hands are kept away from the cutting area and blade. Keep
one hand on the auxiliary handle or motor housing. If both hands are
holding the tool they cannot be cut by the blade
• Do not attempt to cut material thicker than detailed in the Specifications
section of this manual
• Adjust the cutting depth to the thickness of the workpiece i.e. less than
a full tooth of the blade should be visible below the workpiece
• Ensure that work is correctly supported. Large panels may sag under
their own weight and bind the saw blade. Supports must be placed
under the panel on both sides, close to the line of cut and near the edge
of the panel
• Ensure all supports and power cables are completely clear of the
cutting path
• Always secure the workpiece to a stable platform, ensuring body
exposure is minimised, avoiding blade binding, or loss of control
• For accuracy of cut, and to avoid blade binding, always use a rip fence
or straight edge guide
• Never hold a workpiece in your hand or across your legs whilst cutting
• Always stand at an angle to the tool when operating

• Be aware that the blade will project from the underside of the workpiece
• Do not reach beneath the workpiece where the guard cannot protect
you from the blade
• Note the direction of rotation of the motor and the blade
• Inspect the workpiece and remove all nails and other embedded objects
prior to starting work
• Do not apply any sideways or twisting force to the blade whilst cutting
• If a cut does not extend to the edge of the workpiece, or if the blade
binds in the cut, allow the blade to come to a complete stop and lift the
saw out of the workpiece
• Do not attempt to free a jammed blade before first disconnecting the
machine from power
• Do not move the saw backwards at any time whilst cutting
• Beware of projected waste. In some situations, waste material may be
projected at speed from the cutting tool. It is the user’s responsibility
to ensure that other people in the work area are protected from the
possibility of projected waste
• If you are interrupted when operating the saw, complete the process
and switch off before diverting your attention
• The blade bolt and washers were specially designed for your saw. For
optimum performance and safety of operation never use damaged or
incorrect bolt/blade washers
• Periodically check that all nuts, bolts and other fixings have not
loosened, tighten where necessary
The tool must be used only for its prescribed purpose. Any use other than
those mentioned in this manual will be considered a case of misuse. The
user, and not the manufacturer, shall be liable for any damage or injury
resulting from such cases of misuse.
The manufacturer shall not be liable for any modifications made to the tool
nor for any damage resulting from such modifications.

Transportation
• Lift the mitre saw only when the
saw arm is locked in the down
position, the saw is switched off
and the plug is removed from the
power point.
• Only lift the saw by the Carrying
Handle (8) or outer castings (Fig.
A). Do not lift the saw using the
guard or Operating Handle (7).
Bench mounting
The saw base has holes in each
corner to facilitate bench mounting
(Fig. B).
• Mount the saw to a level,
horizontal bench or work table
using bolts (not supplied) through
the fixing holes in the saw base
• Alternatively, mount the saw on 13mm or thicker plywood, and clamp
the plywood to the work support; this makes it easy to re-locate the
saw, clamping it to a work support wherever needed
CAUTION: Make sure that the mounting surface is not warped as an
uneven surface can cause binding and inaccurate sawing
Stabiliser bar
When the saw is not fitted to a
bench, always fit the Stabiliser Bar
(40) into the holes at the rear of the
saw base (Fig. C). The stabiliser
helps prevent the saw from tipping
backwards when the slide action
is used.
Release knob
The Release Knob (6) is provided for
holding the cutting head down whilst
transporting or storing the mitre saw
(Fig. D). Never use the saw with the
release knob locking the head down.
Slide lock
When tightened, the Slide Lock
(29) prevents the saw head from
sliding. Tighten the slide lock during
transportation (Fig. E)
Mitre table lock
The Mitre Table Lock (25) is used
to lock the table at the desired mitre
angle (Fig. F). The mitre saw cuts
from 0° to 52° both left and right. To
adjust the mitre angle:
1. Loosen the mitre table lock
2. Using the mitre table handle, adjust
the mitre angle to the desired

from 0° to 45° to the left and right. To
adjust the bevel angle:
1. Loosen the bevel lock and pull out
the 0° Bevel Adjuster (18)
2. Adjust the saw arm to the desired
bevel angle
3. Retighten the bevel lock to secure
in position
WARNING: Be sure to tighten the bevel lock before making a cut. Failure
to do so could result in the saw arm moving during the cut and cause
serious personal injury.
Bevel adjuster
The Bevel Adjuster (18) must be
pulled out before the bevel angle can
be adjusted (Fig. H).
To return the saw arm to the vertical
(0° bevel) position:
1. Move the saw arm to the left and
push in the 0° bevel adjuster
2. Return the saw blade to
the vertical position, it will
automatically stop at the 0° bevel
position
3. Tighten the bevel lock
Clamp assembly
• The Clamp Assembly (10) can be mounted to the fence, either sideof the
saw blade, to suit the task at hand (Fig. I).
• Use the Clamp Assembly Lock (11) at the back of the fence to secure
the clamp assembly in position (Fig. J).
Rotating lower
blade guard
The Rotating Lower Blade Guard
(12) provides protection from both
sides of the blade (Fig. K). It retracts
over the Upper Blade Guard (9)
as the saw is lowered into the
workpiece.
Dust bag
The Dust Bag (15) fits over the Dust
Extraction Port (27) (Fig. L). For most
efficient operation, empty the dust
bag when it is no more than half full;
this allows better air flow through
the bag.
Attaching
the side bars
• The Side Support Bars (37) help
to support the material when
working with long workpieces.
There are two Location Holes
(38) for a support bar on either
side of the table. Loosen the Lock
Screws (39) with the 6mm hex
key. Ensure the side bars are fully
inserted before using them to
support the workpiece (Fig. M).

Trench depth adjustment
• In its normal position, the
Trenching Stop (31) permits the
saw blade to cut right through a
workpiece
• When the saw arm is lifted, the
trenching stop can be moved
to the left so that the Trenching
Depth Adjustment Screw (30)
contacts the stop as the saw
arm is lowered. (Fig. O). This
restricts the cut to a ‘trench’ in the
workpiece.
• The depth of the trench can be adjusted with the Trenching Depth
Adjustment Screw (30) (Fig. P) and locked in position with the
Trenching Depth Lock Nut (32) (Fig. Q).
