q.  Check functioning of the lower guard spring. Repair the guard and its spring before use when 

they do not work properly. 

Lower guard functioning may be slowed down due to damaged parts, sticky 

sediments or building up of layers of wastes.

r.  Manual pulling off the lower guard is allowed only when special cutting is performed, such as “in-

depth 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 guard works automatically.

s.  Always ensure the lower guard covers cutting blade before putting the circular saw on the work 

bench 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.

CAUSES OF KICK BACK AND WAYS TO REDUCE IT

Ɣ

Kick back is sudden lift and backing of the saw in the line cutting line towards operator. This is caused by  
cutting blade being pinched or incorrectly guided.

Ɣ

When 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.

Ɣ

If the cutting blade is warped 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 blade and the 
saw, and kick back towards operator.

Kick back is effect of improper use of circular saw, or wrong operating procedures or conditions, and can be 
avoided by observing applicable, below mentioned precautions: 

Precautions

Ɣ

Do not use damaged or deformed cutting blades.

Ɣ

Use only cutting blades that are recommended by the manufacturer and comply with the standard EN 847-1.

Ɣ

Do not use cutting blades without sintered carbide tips on teeth.

Ɣ

Use personal protection measures, such as:

Ɣ

earmuff protectors to reduce risk of hearing damage,

Ɣ

eye shield,

Ɣ

respiratory system protection to reduce risk of harmful dusts inhalation,

Ɣ

gloves for maintenance of cutting blades and other rough and sharp materials (hold cutting blades by 
mount hole whenever possible).

Ɣ

Connect dust extraction system when cutting wood.

Safe operation

Ɣ

Match cutting blade with material that you plan to cut.

Ɣ

Never use the saw for cutting materials other than wood and wood-like.

Ɣ

Do not use the saw without guard or when the guard is blocked. 

Ɣ

Floor close to the machine work place must be kept tidy and without loose materials and protrusions.

Ɣ

Provide appropriate work place illumination.

Ɣ

Machine operator must be properly trained for use, operation and working with the machine.

Ɣ

Use only sharp cutting blades.

Ɣ

Observe maximum speed marked on the cutting blade.

Ɣ

Ensure that parts are used in accordance with the manufacturer instructions.

Ɣ

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.

CAUTION! This device is designed to operate indoors.

The design is assumed to be safe, protection measures and additional safety systems are used, 
nevertheless there is always a small risk of operational injuries.

CONSTRUCTION AND USE

Circular saw is a hand-held power tool with insulation class II. It is driven by a single-phase commutator 
motor. This type of power tools is widely used for cutting wood and objects made of wood-like materials 
that match with the tool size. Do not use the saw for cutting firewood. Attempts to use the circular saw 
for purposes other than specified will be considered an improper use. Use the circular saw only with
