GENERAL SAFETY RULES
Warning! Read all instructions, Failure to follow all instructions listed
below may result in electric shock, fire and/or serious injury. The term
“Power Tool” in all of the warnings listed below refers to your mains
operated (corded) power tool or battery operated (cordless) power tool.
SAVE THESE INSTRUCTIONS
1) WORK AREA
a) Keep work area clean and well lit. Cluttered and dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as in the
presence of flammable liquids, gases, or dust. Power tools create sparks
which may ignite the dust or fumes.
c) Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
2) ELECTRICAL SAFETY
a) Power tool plugs must match the outlet. Never modify the plug in any
way. Do not use any adapter plugs with earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces such as pipes,
radiators, ranges and refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or
unplugging the power tool. Keep cord away from heat, oil, sharp edges or
moving parts. Damaged or entangled cords increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension cord suitable for
outdoor use. Use of a cord suitable for outdoor use reduces the risk of
electric shock.
3) PERSONAL SAFETY
a) Stay alert, watch what you are doing and use common sense when
operating a power tool. Do not use a power tool while you are tired or under
the influence of drugs, alcohol or medication. A moment of inattention while
operating power tools may result in serious personal injury.
b) Use safety equipment. Always wear eye protection. Safety equipment such
as dust mask, non-skid safety shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.
c) Avoid accidental starting. Ensure the switch is in the off position before
plugging in. Carrying power tools with your finger on the switch or plugging in
power tools that have the switch on invites accidents.
d) Remove any adjusting key or wrench before turning the power tool on. A
wrench or a key left attached to a rotating part of the power tool may result in
personal injury.

e) Do not overreach. Keep proper footing and balance at all times. This enables
better control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair,
clothing and gloves away from moving parts. Loose clothes, jewellery or long
hair can be caught in moving parts.
g) If devices are provided for the connection of dust extraction and collection
facilities, ensure these are connected and properly used. Use of these devices
can reduce dust related hazards.
4) POWER TOOL USE AND CARE
a) Do not force the power tool. Use the correct power tool for your application.
The correct power tool will do the job better and safer at the rate for which it
was designed.
b) Do not use the power tool if the switch does not turn it on and off. Any power
tool that can not be controlled with the switch is dangerous and must be repaired.
c) Disconnect the plug from the power source before making any adjustments,
changing accessories, or storing power tools. Such preventive safety measures
reduce the risk of starting the power tool accidentally.
d) Store idle power tools, unplugged & out of the reach of children and do not
allow persons unfamiliar with the power tool or these instructions to operate
the power tool. Power tools are dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may affect the power tools
operation. If damaged, have the power tool repaired before use. Many
accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc., in accordance with these
instructions and in the manner intended for the particular type of power tool,
taking into account the working conditions and the work to be performed.
Use of the power tool for operations different from those intended could result in a
hazardous situation.
5) SERVICE
a) Have your power tool serviced by a qualified repair person using only
identical replacement parts. This will ensure that the safety of the power tool
is maintained.

DANGER! Keep hands away from cutting area and the blade. Keep
your second hand on auxiliary handle, or motor housing. If both hands
are holding the saw, they cannot be cut by the blade.
a) Do not reach underneath the workpiece. The guard cannot protect you from
the blade below the workpiece.
b) 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.
c) 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 minimize body exposure, blade binding, or loss of control.
d) 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.
e) When ripping always use a rip fence or straight edge guide. This improves
the accuracy of cut and reduces the chance of blade binding.
f) Always use blades 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.
g) 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.
Further safety instructions for all saws
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 toward 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 toward 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.
Kickback is the result of saw misuse and/or incorrect operating procedures or
conditions and can be avoided by taking proper precautions as given below.
a) Maintain a firm grip with both hands on the saw and position your arms to
resist kickback forces. Position your body to either side of the blade, but not
in line with the blade. Kickback could cause the saw to jump backwards, but
kickback forces can be controlled by the operator, if proper precautions are taken.
b) When blade is binding, or when interrupting a cut for any reason, release
the trigger and hold the saw motionless in the material until the blade
comes to a complete stop. Never attempt to remove the saw from the work
or pull the saw backward while the blade is in motion or kickback may occur.
Investigate and take corrective actions to eliminate the cause of blade binding.
c) When restarting a saw in the workpiece, centre the saw blade in the kerf
and check that saw teeth are not engaged into the material. If saw blade is
binding, it may walk up or kickback from the workpiece as the saw is restarted.
d) Support large panels to minimise the risk of blade pinching and kickback.
Large panels tend to sag under their own weight. Supports must be placed under
the panel on both sides, near the line of cut and near the edge of the panel.

!
!
!
!
e) Do not use dull or damaged blades. Unsharpened or improperly set blades
produce narrow kerf causing excessive friction, blade binding and kickback.
f) Blade depth and bevel adjusting locking levers must be tight and secure
before making cut. If blade adjustment shifts while cutting, it may cause binding
and kickback.
g) Use extra caution when making a "plunge cut" into existing walls or other
blind areas. The protruding blade may cut objects that can cause kickback.
h) Check lower guard for proper closing before each use. Do not operate the saw
if lower guard does not move freely and close instantly. Never clamp or tie the
lower guard into the open position. If saw is accidentally dropped, lower guard may
be bent. Raise the lower guard with the retracting handle and make sure it moves
freely and does not touch the blade or any other part, in all angles and depths of cut.
i) Check the operation of the lower guard spring. If the guard and the spring are
not operating properly, they must be serviced before use. Lower guard may
operate sluggishly due to damaged parts, gummy deposits, or a build-up of debris.
j) Lower guard may be retracted manually only for special cuts such as "plunge
cuts" and "compound cuts." Raise lower guard by retracting handle and as
soon as blade enters the material, the lower guard must be released. For all
other sawing, the lower guard should operate automatically.
k) Always observe that the lower guard is covering the blade before placing saw
down on bench or floor. An unprotected, coasting blade will cause the saw to
walk backwards, cutting whatever is in its path. Be aware of the time it takes for
the blade to stop after switch is released.
l) Recommendation for the use of a residual current device with a rated residual
current device of 30mA or less.
Additional safety instructions for laser lights
The laser light/laser radiation used in the Ozito Circular Saw OZCS1800WA laser is Class 2
with maximun 1mW and 650nm wavelengths. These lasers do not normally present an
optical hazard, although staring at the beam may cause flash blindness.
Warning! Do not stare directly at the laser beam. 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.
• Never aim the beam at any person or an object other than the work piece.
• The laser beam shall not be deliberately aimed at personnel and shall be
prevented from being directed towards the eye of a person for longer than 0.25s.
•Always ensure the laser beam is aimed at a sturdy work piece without reflective
surface’, i.e. wood or rough coated surfaces are acceptable. Bright shiny reflective
sheet steel or the like 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 with a
different type. Repairs must only be carried out
by a power tool repairer.
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 Australian standards, AS 2397 and AS/NZS2211
for more information on Lasers.

Fitting the Blade
Warning! Disconnect the plug from the power source before assembling,
making any adjustments or changing accessories. Such preventive safety
measures reduce the risk of starting the tool accidentally.
1. Press the spindle lock button (3) and using the blade spanner (25) turn until
spindle lock button (3) engages. Whilst depressing the spindle lock button (3),
turn the blade spanner (25) counter-clockwise and remove blade bolt (18) and
outer blade flange (16).
2. Ensure blade flanges and bolt is clean of sawdust, grease, etc.
3. Retract the lower blade guard (15) all the way up into the upper blade guard
(5). While retracting the lower blade guard (15), check operation and condition
of the lower guard spring.
4. Make sure the saw teeth and arrow on the blade (19) point in the same
direction as the arrow on the upper blade guard (5).
5. Slide blade (19) through slot in the baseplate (14) and mount it against the
inner blade flange (17) on the shaft. Make sure the large diameter of the blade
flanges lay flush against the blade (19).
6. Fit outer blade flange (16). First tighten blade bolt (18) to finger tight. Engage
spindle lock button (3). Whilst depressing the spindle lock button (3), tighten
blade bolt (18) firmly with the blade spanner (25) supplied.
7. Before connecting the saw to a power source, ensure that:
• the spindle lock button (3) is released
• the blade (19) rotates freely
• the lower blade guard (15) operates correctly
Note: Do not modify blade spanner (25) to elongate it, since it may lead to over
tightening of the blade bolt (18).
Depth Adjustment
Disconnect plug from power source. Loosen the depth adjustment lever (21). Hold
the baseplate (14) down with one hand and raise or lower the saw by the soft grip
handle (23). Tighten depth adjust lever (21) at the depth setting desired. Check
desired depth.
To obtain minimum splintering while operating, ensure that no more than one
tooth protrudes through the timber.
90º Cutting Angle Check
Disconnect plug from power source. Set baseplate (14) to maximum depth of cut
setting. Loosen bevel adjustment knob (10), set to 0º on bevel scale (9), retighten
bevel adjustment knob (10) and check for 90º angle between the blade (19) and
bottom plane of the baseplate (14), with a square.
Bevel Adjustment
Disconnect plug from power source. The baseplate (14) can be adjusted up to 45º
by loosening the bevel adjustment knob (10) at the front of the saw. Align to
desired angle on calibrated bevel scale (9). Then tighten bevel adjustment knob (10).
Because of the increased amount of blade engagement in the work and decreased
stability of the baseplate (14), blade binding may occur. Keep the saw steady and
the baseplate (14) firmly on the work piece.

Line Guide
For a straight 90º cut, use the cutting guide notch (13a) in the baseplate (14). For 45º
bevel cuts, use cutting guide notch (13b). The cutting guide notch will give an
approximate line of cut. Make sample cuts in scrap timber to verify actual line of cut.
This will be helpful because of the number of different blade types and thicknesses
available. To ensure minimum splintering on the good side of the material to be cut,
face the good side down.
Switch
Warning! When starting the circular saw, hold it securely with both hands.
The torque from the motor can cause the tool to twist.
To turn the tool “ON”, depress the lock-off button (2) and squeeze the on/off switch (1).
To turn the tool “OFF”, release the on/off switch (1), which is spring loaded and will
return to “OFF” automatically.
Your saw should be running at full speed BEFORE starting the cut and turned off
only AFTER completing the cut. To increase switch life, do not run switch on and off
while cutting.
Using the laser light
Warning! Do not stare directly at the laser beam.
Always ensure that the laser light is turned off when the tool is not in use.
Do not, under any circumstances, point the laser beam at any person or animal.
Always ensure that the laser beam is only directed at the work piece.
Do not deliberately direct the laser beam towards the eye of a person for longer than
0.25 seconds, whether the tool is in use or not.
Always ensure that the laser beam is aimed at solid work pieces with non-reflective
surfaces such as raw timber. Transparent, shiny or reflective surfaces are not suitable for
laser use as the laser beam could be directed back to the operator or bystanders
causing injury.
1. Select work piece and mark the cutting line.
2. Select angle and depth of cut on the saw as necessary.
3. Position the saw on the work piece with the front edge of the base plate resting on
the work piece. Ensure the blade is not touching the work piece.
4. Switch the laser light on by depressing the laser light switch (4).
5. Line up the laser light with the cutting line on the work piece.
6. Turn on the motor by engaging lock-off button (2) and squeezing the on/off
switch (1). Allow the motor to reach maximum speed before starting the cut.
7. Maintain a firm grip and slowly push the saw forward without forcing it through the
work piece while keeping the laser guide on the cutting line.
8. When the cut has been completed, release the on/off switch and wait for the blade
to come to a complete stop.
9. Switch the laser light off by depressing the laser light switch (4).
10. Remove the saw from the work piece.

General Cuts
Always hold the soft grip handle (23) with one hand and the front handle (7) with
the other.
Warning! Always make sure either hand does not interfere with the free
movement of the lower blade guard (15).
Maintain a firm grip and operate the on/off switch (1) with a positive action.
Never force the saw. Use light and continuous pressure.
Warning! After completing a cut and the on/off switch (1) has been released,
be aware of the necessary time it takes for the blade (19) to come to a
complete stop during coast down. Do not allow the saw to brush against your
leg or side, since the blade guard (15) is retractable, it could catch on your
clothing and expose the blade (19). Be aware of the necessary blade exposure
that exist in both the upper and lower blade guard areas.
When cutting is interrupted, to resume cutting, depress the lock-off button (2) and
squeeze the on/off switch (1) and allow the blade (19) to reach full speed, re-enter
the cut slowly and resume cutting.
When cutting across the grain, the fibres of the wood have a tendency to tear and
lift. Advancing the saw slowly minimizes this effect. For a finished cut, a cross cut
blade or mitre blade is recommended.
Cutting Masonry/Metal
This tool is not recommended for metal or masonry abrasive wheels. If you use
your saw for cutting these materials your warranty will be voided.
Warning! This machine is not intended to be used with Wet Diamond
Wheels. Using water or other liquid coolants with this machine may result
in electrocution or shock.
Cutting Large Sheets
Large sheets and long boards sag or bend, depending on support. If you attempt
to cut without levelling and properly supporting the piece, the blade will tend to
bind, causing KICKBACK and extra load on the motor.
Use timber underneath the sheet or board to raise it for support. This will ensure a
safe and stable cutting operation. Support the panel or board close to the cut. Be
sure to set the depth of the cut so that you cut through the sheet or board only
and not the table or work bench. If the sheet or board to be cut is too large for a
table or work bench, use supporting timbers on the floor and secure.
Rip Cuts
The combination blade provided with your saw is for both cross cuts and rip cuts.
Ripping is cutting lengthwise with the grain of the wood. Rip cuts are easy to do with
a rip fence (24). To attach rip fence (24), insert rip fence (24) through rip fence slots
(11) in baseplate (14) to desired width and secure with the rip fence lock knob (12).
Rip Board Guide
When rip cutting large sheets, the rip fence (24) may not allow the desired width of
cut. Clamp or nail a straight piece of 25mm thick timber to the sheet as a guide.
Use the right side of the baseplate (14) against the board guide.
