ible with the tool cannot be properly protected and are not safe.
The grinding surface of centre depressed wheels must be mounted below the plane of the guard lip. An improperly
mounted wheel that projects through the plane of the guard lip cannot be adequately protected.
The guard must be secured to the tool and placed in a position which ensures maximum safety, so that the smallest
possible area of the disk is unprotected towards the operator. The guard helps to protect the operator from broken fragments
of the disk and prevents accidental contact with the disk.
The disk must be used as intended. For example: do not grind with disks designed for cutting. Abrasive disks for cutting
are designed for circumferential load, and the lateral forces applied to such a disk may destroy it.
Always use undamaged fi xing disks, whose dimensions must be compatible with the grinding disk. Adequate fi xing disks
for the abrasive disk reduce the risk of damaging the grinding disk. The fi xing disks for cutting disks may diff er from the fi xing disks
designed for grinding disks.
Do not use worn abrasive disks from bigger tools. An abrasive disk of a bigger diameter is not adapted to a bigger rotational
speed of smaller tools and may break.
Warnings related to grinding with abrasive paper
Do not use discs with abrasive papers of an excessive size. While selecting the grinding wheel, follow the guidelines of
the manufacturer. Abrasive paper which signifi cantly exceeds the size of the disc may cause injuries and increases the risk of
seizure, tearing or rebounding towards the operator.
Warnings related to work with wire brushes
Be careful, since fragments of wires are ejected from the brush also during normal work. Do not overload the wires exert-
ing excessive force on the brush. The wires may easily perforate light clothes and/or the skin.
If it is recommended to use guards while working with wire brushes, preclude any contact of the brush with the guard.
The diameter of the wire brush may increase due to the load and the centrifugal force.
PREPARATION FOR WORK
ATTENTION! All the operations mentioned in this point must be realised with the power supply off .
- the battery must be disconnected from the tool!
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, particularly 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 disconnect 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 tool 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 charging dock provided. Li-ION batteries do not show the so
called "memory eff 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 prolonged
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
