GENERAL PoWER TooL SAfETy WARNINGS

Warning! Read all safety warnings and all instructions. Failure to follow the
warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.

1) Work area safety
a) Keep work area clean and well lit. Cluttered or 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.
f)

If operating a power tool in a damp location is unavoidable, use a residual current

device (RCD) protected supply. Use of an RCD 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 personal protective equipment. Always wear eye protection. Protective

equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used
for appropriate conditions will reduce personal injuries.

c) Prevent unintentional starting. Ensure the switch is in the off-position before
connecting to power source and/or battery pack, picking up or carrying the tool.

Carrying power tools with your finger on the switch or energising 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.

18V CIRCULAR SAW ERI490CSW

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 dust collection 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 cannot be controlled with the switch is dangerous and must be repaired.

c)

Disconnect the plug from the power source and/or the battery pack from the
power tool 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 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 tool’s
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, 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) Battery tool use and care
a) Recharge only with the charger specified by the manufacturer. A charger that

is suitable for one type of battery pack may create a risk of fire when used with another
battery pack.

b) Use power tools only with specifically designated battery packs. Use of any
other battery packs may create a risk of injury and fire.

c) When battery pack is not in use, keep it away from other metal objects, like
paper clips, coins, keys, nails, screws or other small metal objects, that can
make a connection from one terminal to another. Shorting the battery terminals

together may cause burns or a fire.

d) Under abusive conditions, liquid may be ejected from the battery; avoid
contact. If contact accidentally occurs, flush with water. If liquid contacts eyes,
additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

6) 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.

SAfETy WARNINGS foR ALL SAWS

a) 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.

b) Do not reach underneath the workpiece. The guard cannot protect you from the

blade below the workpiece.

c) 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.

d) 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.

e) Hold power tool by insulated gripping surfaces when performing an operation

where the cutting tool may contact hidden wiring. Contact with a “live” wire will also
make exposed metal parts of the power tool “live” and shock the operator.

f) When ripping always use a rip fence or straight edge guide. This improves the

accuracy of cut and reduces the chance of blade binding.

g) 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.

h) 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

Kickback causes and related warnings

- 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.

18V CIRCULAR SAW ERI490CSW

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.

SAFETY INSTRUCTION FOR YOUR CIRCULAR SAW WITH INNER PENDULUM
GUARD
a) 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.
b) 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.
c) 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.
d) 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.

VIBRATIoN

The European Physical Agents (Vibration) Directive has been brought in to help reduce
hand arm vibration syndrome injuries to power tool users. The directive requires power tool
manufacturers and suppliers to provide indicative vibration test results to enable users to make
informed decisions as to the period of time a power tool can be used safely on a daily basis
and the choice of tool.
Further Advice can be found at www.hse.gov.uk

Vibration total values (triax vector sum) determined according to EN 60745:

Cutting wood:

a

h,W

=4.51m/s²

Uncertainty K=1.5m/s²

The declared vibration emission value should be used as a minimum level and should be used
with the current guidance on vibration.
Calculating the actual period of the actual period off use can be difficult and the HSE website
has further information.

The declared vibration emission been measured in accordance with a standardised test stated
above and may be used to compare one tool with another tool.
The declared vibration emission value may also be used in a preliminary assessment of
exposure.

Warning: The vibration emission value during actual use of the power tool can differ from

the declared value depending on the ways in which the tool is used dependant on the
following examples and other variations on how the tool is used:­How the tool is used and the materials being cut or drilled.
The tool being in good condition and well maintained.
The use the correct accessory for the tool and ensuring it is sharp and in good condition.
The tightness of the grip on the handles.
And the tool is being used as intended by its design and these instructions.

While working with this power tool, hand/arm vibrations occur. Adopt the correct
working practices in order to reduce the exposure to vibration.

This tool may cause hand-arm vibration syndrome if its use is not adequately
managed.

Warning: identify safety measures to protect the operator that are based on an

estimation of exposure in the actual conditions of use (taking account of all parts of the
operating cycle such as the times when the tool is switched off and when it is running idle in
addition to the trigger time).Note The use of other tools will reduce the users’ total working
period on this tool.

Helping to minimise your vibration exposure risk.
ALWAYS use sharp chisels, drills and blades.
Maintain this tool in accordance with these instructions and keep well lubricated (where
appropriate).

direction. Tilt the base plate away from the machine
until the required cutting angle is adjusted on the
angle scale (5 ). Tighten the bevel lock knob (6) by
turning it in clockwise direction.
Note:The adjustment screw (27) is used to set the
accurate bevel angle at 0°. (See Fig.4)

3. CUTTING GUIDE (See Fig.5)

The cutting mark 0° (9) indicates the position of the
saw blade for right-angled cuts. The cutting mark 45°
(8) indicates the position of the saw blade for 45° cuts.
Both cutting marks include the width of the saw
blade. Always guide the saw blade off of the drawn­up cutting line so that the required measure is not
reduced by the width of the saw blade. For this,
choose the corresponding notch side of the cutting
mark 0° (9) or 45° (8) as shown in the illustration.

Note: It is best to carry out a trial cut.

4. HEX KEY STORAGE (See Fig.6)

The hex key provided can be placed in the area under
the machine motor.

5. DUST/CHIP EXTRACTION (See Fig.7)

Fasten the vacuum adapter (15) onto the dust
extraction outlet (28) until it latches. Directly connect
a suitable vacuum hose to the adapter.
Note: There is an arrow on the surface of the adapter
which show the tighten direction.

The vacuum adapter must be mounted
anytime.

Clean the vacuum adapter regularly to ensure
optimum dust extraction. The vacuum cleaner must
be suitable for the material to be worked.

STARTING OPERATION

1. SWITHCING ON AND OFF

For starting operation the machine, actuate the lock­off button (1) first, and then press and hold the On/off
switch (2) afterwards.
To switch off the machine, release the On/off switch (2).

For safety reasons the On/Off switch of the
machine cannot be locked; it must remain
pressed during the entire operation.

2. ELECTRICAL BRAKE

An integrated electrical brake immediately reduces
the speed of the saw together with the saw blade
after switching off the machine.

Always use a blade suited to the material and material
thickness to be cut. The quality of cut will improve as
the number of blade teeth increase. Always ensure
the work-piece is firmly held or clamped to prevent
movement. Support large panels close to the cut line.
Any movement of the material may affect the quality
of the cut. The blade cuts on the upward stroke and
may chip the uppermost surface or edges of your
work piece when cutting, ensure your uppermost
surface is a non visible surface when your work is
finished.

1. PARALLEL GUIDE (See Fig.8)

Used for making cuts parallel to a work piece edge
at a chosen distance. Slide the parallel guide arm
through both fixtures to achieve the required cutting
distance and tighten screw to lock into position
(7). It can be used from both sides of the base plate

(11).There is a cutting guide notch on the front of the
base plate (11) for using with a parallel guide (10).
For straight cuts, use the 0° guide mark to align with
your parallel guide scale. For a 45° bevel cut, use the
45° guide mark to align with your parallel guide scale.
Securely clamp the parallel guide (10) (See Fig. 7).
Always make a trial cut to check the setting.

2. BEVEL CUTS (See Fig.9)

Set required bevel angle between 0° and 50°. Do not
use the depth of cut scale when making bevel cuts
due to possible inaccuracy.
Loosen the base plate bevel lock button (6) and
rotate the base plate (11) to set the bevel angle
using the base plate angle scale (5) provided. Then
clamp the base plate (11) position using the lock
(6) (See Fig. 5). Finally, check the angle and ensure
the base plate is firmly clamped. The angle scale (5)
on the base plate (11) are accurate for most general
purposes but it is recommended for accurate work to
set the angle with a protractor and make a test cut
on other material. Do not use the depth of cut scale
when making bevel cuts due to possible inaccuracy.
