Stay alert, pay attention to what you do and keep common 

sense while working with the power tool. Do not use a power 

tool when you are tired or under the in

fl

 uence of alcohol 

or medication.

 Even a moment of inattention while working can 

lead to serious personal injury.

Use personal protective equip-

ment. Always wear eye protection.

 The use of personal pro-

tective equipment such as dust masks, anti-slip safety shoes, 

helmets and hearing protection reduce the risk of serious per-

sonal injury.

Prevent accidental operation. Make sure that the 

electric switch is in the “o

ff

 ” position before connecting to 

the power supply and / or battery, lifting or moving the pow-

er tool.

 Moving the power tool with the 

fi

 nger on the switch or 

powering the power tool, when the switch is in the “on” position 

can lead to serious injuries.

Before turning on the power tool 

remove any keys and other tools that were used to adjust 

it.

 The key left on the rotating parts of the power tool can lead 

to serious injuries.

Do not reach and do not lean too far. Keep 

the right attitude and balance all the time.

 This will allow 

easier control over the power tool in case of unexpected work 

situations.

Dress accordingly. Do not wear loose clothing 

or jewelry. Keep your hair and clothing away from moving 

parts of the power tool.

 Loose clothing, jewelry or long hair 

can be caught by moving parts.

If the devices are 

fi

 tted for the 

connection of dust extraction or dust collection, make sure 

that they are connected and used properly. 

The use of dust 

extraction reduces the risk of dust hazards. 

Do not let the ex-

perience acquired from frequent use of the tool resulted in 

carelessness and ignoring safety rules.

 Carefree action can 

cause serious injuries in a fraction of a second. 

Hold the power 

tool by insulated gripping surfaces, when performing an op-

eration where the fastener may contact hidden wiring or its 

own cord.

 Fastener contacting a “live” wire may make exposed 

metal parts of the power tool “live” and could give the operator 

an electric shock.

Use and care of the power tool 

Do not overload the power tool. Use the power tool appro-

priate for the selected application.

 The right power tool will 

provide a better and safer job if used according to the designed 

load. 

Do not use the power tool, if the electric switch does 

not allow switching on and o

ff

 .

 Power tool, which cannot be 

controlled by means of a power switch is dangerous and must be 

returned for repair.

Disconnect the plug from the power socket 

and / or remove the battery if it is detachable from the pow-

er tool before adjusting, changing accessories or storing the 

tool.

 Such preventive measures will allow you to avoid accidentally 

turning on the power tool.

Keep the tool out of the reach of chil-

dren, do not let people who do not know how to operate 

the power tool or these instructions use a power tool.

 Power 

tools are dangerous in the hands of untrained users. 

Maintain 

power tools and accessories. Check the tool for mismatch-

es or jams of moving parts, damage to parts and any other 

conditions that may a

ff

 ect the operation of the power tool. 

Damage must be repaired before using the power tool.

 Many 

accidents are caused by incorrectly maintained tools.

Keep cut-

ting tools sharp and clean.

 Properly maintained cutting tools 

with sharp edges are less prone to jamming and are easier to 

control when working. 

Use power tools, accessories and 

inserted tools etc. in accordance with these instructions, 

taking into account the type and conditions of work.

 The 

use of tools for work other than designed is likely to result in a 

dangerous situation.

Handles and gripping surfaces must be 

dry, clean and free from oil and grease.

 Slippery handles and 

gripping surfaces do not allow for safe operation and control of 

the tool in dangerous situations.  

Repairs

Repair the power tool only in authorized facilities using only origi-

nal spare parts. 

This ensures proper operation safety of the power tool

PREPARATION FOR WORK  

Safety recommendations for battery loading

Attention! 

Before loading may start make sure the body of the 

charger, the cable and the plug are not broken or damaged. It 

is prohibited to use a damaged loading dock and charger! For 

the purpose of loading batteries only the charging dock and the 

charger provided may be used. Using another charger may be 

a cause of 

fi

 re or damage the tool. Batteries may be charged 

only in a dry room, protected from unauthorised persons, par-

ticularly children. Do not use the charging dock and the charger 

without permanent supervision of an adult! If it is necessary to 

leave the room where loading is taking place, it is required to dis-

connect the charger from the mains, removing the charger from 

the mains socket. In case when smoke comes out of the charger, 

or a strange smell is emitted, etc., it is required to immediately 

remove the plug of the charger from the mains socket! The drill 

and automatic return screwdriver is provided with an unloaded 

battery, so before work may commence, it is required to charge 

it following the procedure below, using the charger and charg-

ing dock provided. Li-ION batteries do not show the so called 

“memory e

ff

 ect”, so it is allowed to charge them at any moment. 

However, it is recommended to discharge them during normal 

work, and then load them to their full capacity. If due to the nature 

of the task it is not possible to do so each time, then it is required 

to do it at least from time to time. Under no circumstances is it 

allowed to discharge the batteries short-circuiting the electrodes, 

since this would cause irreversible damage! It is also prohibited 

to check the load of the batteries, short-circuiting the electrodes 

for sparking.

Storage of the battery

In order to prolong the life of the battery, it is required to provide 

adequate storage conditions. The batteries can go through ap-

proximately 500 „loading - discharging” cycles. The battery must 

be stored between 0 and 30°C, at the relative humidity of 50%. 

In order to store the battery for a prolonged period, it is required 

to charge it to approximately 70% of its capacity. In case of pro-

longed storage, it is required to recharge the battery once a year. 

Do not permit excessive discharging of the battery, since this 

would reduce its life and may cause irreversible damage. During 

storage, the battery will be gradually unloading due to leakage 

conductance. The process of automatic unloading depends on 

the temperature of storage, since the higher the temperature, 

the fastest the process. In case of incorrect storage of batteries, 

there is a danger of electrolyte leakage. In case of leakage, it 

is required protect the leakage with neutralizing agent. In case 

of contact of electrolyte with the eyes, it is required to rinse the 

eyes abundantly, and then immediately seek medical assistance. 

It is prohibited to use a tool with a damaged battery. 

In case 

the battery is completely worn out, it is required to deposit it at a 

special point dedicated to disposal of such waste.

Transport of the batteries

Lithium-ion batteries are in accordance with legal regulations 

treated as dangerous waste. The user of the tool may transport 

the tool with the battery or only batteries by land. Then no addi-

tional conditions must be complied with. In transport is realised 

by third parties (for example dispatch through courier service), 

then it is required to proceed in accordance with regulations for 

transport of dangerous materials. Before shipment, contact an 

authorised person. It is prohibited to transport damaged batter-

ies. During transport the battery must be removed from the tool, 

and the exposed contacts protected, e.g. with insulating tape. 

Protect the batteries so that they do not move inside the package 

during transport. It is also required comply with the national reg-

ulations for transport of dangerous materials.
