how to use
CAUTION
This power tool is designed for domes-
tic use and is not intended for industrial
purposes. In case of using the power tool
for industrial or professional purposes,
the manufacturer disclaims the product
warranty liabilities.
1. Pressing force of the drill.
You cannot drill holes more quickly even
if you press the drill with a stronger force
than necessary. It not only damages tip
of drill bit and decreases the efficiency of
operation, but also shortens the life of the
drill tip.
2. When a thick drill bit is used.
Your arm is subjected to larger reaction
force when a thicker drill bit is used. Be
careful not to be moved by the reaction
force. For this, establish a foothold; hold
the unit tightly with both hands perpen-
dicularly to the material being drilled.
3. Torque mechanical adjustment.
Before selecting the torque force ensure
that the switch is in «Off» position and
that the screwdriver doesn’t move. For
switching press the switch button and
adjust rotation speed by turning torque
control in the right direction.
4. Reverse function
The drill is equipped with direction
switch function.
For turning the bit clockwise switch the
rotation direction switch in the left end
position.
For turning the bit counterclockwise
switch the rotation direction switch into
the right end position.
5. Precautions right after using.
Do not put the drill with rotating bit in
place, where there is dust and chips, as
the drilling mechanism can suck them in.
CAUTION
When using the screwdriver follow these
rules:
• continuous use of the drill should not
exceed 15 minutes;
• do not allow mechanical damage
(strikes, falls etc.);
• protect the drill from external sources of
heat and chemically active substances, as

• before disconnecting the tool from the
power source turn off the On/Off switch;
• provide effective cooling and drilling
wastes withdrawal from the tool working
zone;
• check the engine temperature, do not
allow overheating;
