• Hold the insulated surfaces of the saw that are designed for such
purpose whenever the rotating cutting blade can encounter live wires.
Contact of device metal parts with live wire may cause operator's electric shock.
• When ripping always use guide for ripping or edge guide. It improves
cutting accuracy and reduces risk of pinching the rotating cutting blade in
material.
• Use only cutting blades with correct arbour hole diameter. Cutting
blades that do not match seating may operate with eccentric offset, which
causes loss of control over operation.
• Never use damaged or incorrect washers or bolts to install cutting
blade. Washers and fixing bolts for cutting blade installation were designed
especially for circular saw to provide optimal operation and safety of use.
KICK BACK, CAUSES AND WAYS TO REDUCE IT
• Kick back is a sudden lift and moving the saw back in the cutting line
towards operator. This is caused by uncontrolled cutting with cutting blade
being caught, pinched or incorrectly guided.
• When the cutting blade is caught or pinched in material, the blade stops
and motor reaction produces sudden movement of the saw to the back,
towards operator.
• If the saw is unaligned or positioned incorrectly in the object being cut, blade
teeth may hit the upper surface of the material when leaving the material. It
will cause sudden raise of the saw, and kick back towards operator.
CAUTION! Kick back is an effect of improper use of circular saw, or wrong
operating procedures or conditions, and can be avoided by observing
applicable, below-mentioned precautions:
• Hold the circular saw firmly with both hands in position that allows to
resist kick-back. Stand to the side of the circular saw but not in the line
of cutting. Kick back may cause sudden move of circular saw to the back, but
its force can be controlled by operator when appropriate precaution measures
are taken.
• When the cutting blade jams or stops cutting due to any reason,
release the switch button and hold the saw still in the material until
the blade or disc stops completely.
• Never attempt to remove the cutting blade from material being cut nor
pull the saw back when the blade is rotating. It may cause kick back.
Investigate and implement correction actions to eliminate causes of cutting
blade seizing.
• When restarting the saw in the processed material, centre the cutting
blade in the kerf and ensure the blade teeth are not blocked in the
material. When the cutting blade jams during restart, it may slide off or cause
kick back against the processed material.
• Support large boards to minimize risk of pinching and kick back of the
circular saw. Large boards tend to bend under own weight. Place supports
under board on both sides, close to the cutting line and close to the board edge.
• Do not use blunt or damaged cutting blades. Blunt or incorrectly
positioned blade teeth create narrow kerf, excessive friction, jamming of
cutting blade and kick back.
• Firmly set clamps for cutting depth and bevel angle before making a
cut. Change of saw settings during cutting may cause jamming and kick back.
• Be very careful during plunge cutting in division walls. Cutting blade
may encounter objects not visible from the outside and cause kick back.
FEATURES OF LOWER PROTECTIVE GUARD
• Make sure the lower guard is appropriately positioned before each
use. Do not use the saw when the lower guard does not move freely
and does not close immediately. Do not fix and do not leave the lower
guard open. When the saw is accidentally dropped the lower guard may get
deformed. Lift the lower guard with pull-handle and ensure it is free to move
and does not touch the blade nor any other part of the tool for any setting of
cutting depth and angle.
• Check functioning of the lower guard spring. Repair the guard and its
spring before use when they do not work properly. Lower guard may be
malfunctioning and slowed down due to damaged parts, sticky sediments or
building up of layers of wastes.
• Manual pulling off the lower guard is allowed only when special cutting
is performed, such as "plunge cutting" and "compound cutting". Lift
the lower guard with its pull handle. As soon as the cutting blade
sinks in the material the guard must be released. For all other cuts it is
recommended that the lower guard works automatically.
• Always make sure the lower guard covers cutting blade before putting
the circular saw away on the workbench or floor. Uncovered, rotating
blade will move the circular saw back and will cut everything in its way.
Consider time required for stopping the blade after the saw is switched off.
ADDITIONAL SAFETY INSTRUCTIONS
• Do not use damaged or deformed cutting blades.
• Do not use grinding wheels.
• Use only cutting blades that are recommended by the manufacturer and
comply with the standard EN 847-1.
• Do not use cutting blades without sintered carbide tips on teeth.
• Dust of certain wood types may be dangerous to health. Direct physical
contact with dusts may cause allergic reaction and/or respiratory system
diseases of operator or bystanders. Dusts of oak and beech are considered
carcinogenic, especially in connection with wood processing substances
(wood impregnants).
• Use personal protection measures, such as:
- earmuff protectors to reduce risk of hearing damage,
- eye shield,
- respiratory system protection to reduce risk of harmful dusts inhalation,
- gloves for maintenance of cutting blades and other rough and sharp
materials (hold cutting blades by mount hole whenever possible).
• Connect dust extraction system when cutting wood.
• Match cutting blade with material that you plan to cut.
• Never use the saw for cutting materials other than wood and wood-like.
• Do not use the saw without guard or when the guard is blocked.
• Floor close to the machine work place must be kept tidy and without loose
materials and protrusions.
• Provide appropriate work place illumination.
• Machine operator must be properly trained for use, operation and working
with the machine.
• Observe maximum speed indicated on the cutting blade.
• Make sure to use parts in accordance with the manufacturer's instructions.
• If the saw is equipped with laser, replacement with laser of another type is
forbidden and all repairs must be carried out by the service.
• Do not use the tool stationary. It is not designed for use with sawing table.
CORRECT OPERATION AND USE OF BATTERIES
• Battery charging process should be supervised by the user.
• Avoid charging the battery in temperature lower than 0°C.
• Use only the charger recommended by the manufacturer. Using charger
designed for other type of battery brings the risk of fire.
• When the battery is not in use, store it away from metal objects such as
paper clips, coins, keys, nails, screws or any other small metal objects
that can short-circuit the battery connectors. Short-circuit of battery
connectors may cause burns or fire.
• In case of battery damage and/or improper use it may produce
gas. Ventilate room and seek medical attention in case of medical
symptoms. Gas can damage respiratory tract.
• In extreme conditions liquid may leak out of the battery. The liquid
coming out of the battery may cause irritations or burns. When a leak is
found, follow the below procedure:
- Carefully wipe the liquid with a cloth. Avoid contact of the liquid with skin
and eyes.
- In case the liquid gets onto skin, immediately wash the spot abundantly with
clean water, you can also neutralize the liquid with a mild acid, e.g. lemon
juice or vinegar.
- When the liquid gets into eyes, wash it immediately with a lot of clean water
for at least 10 minutes. Seek medical advice.
• Do not use damaged or modified battery. Damaged or modified batteries
may behave unpredictably, causing fire, explosion or risk of injuries.
• Do not expose the battery to humidity or water.
• Always keep the battery away from sources of heat. Do not leave the
battery for a long time in high temperature (in direct sunlight, in proximity
of heaters and wherever the temperature exceeds 50°C).
• Do not expose the battery to fire or excessive temperature. Exposure to
fire or temperature above 130°C may cause explosion.
CAUTION! Temperature of 130°C can be also defined as 265°F.
• Observe all charging instructions. Do not charge the battery in
temperature outside of range defined in the rating data table from the
instruction manual. Incorrect charging or charging in temperature outside of
defined range may damage the battery and increase the risk of fire.
BATTERY REPAIRS
• Do not repair damaged batteries. Battery can be repaired only by the
manufacturer or in an authorised workshop.
• When disposing of the worn out battery, take it to a service point
where you can utilize such dangerous wastes.
