Description
Electric handheld drill machine (drill) is a rotary machine consisting of electric drive and gearbox, on the output shaft of which the possibility of fixing the rig with the help of  a three-cam self-centering chuck is provided.
The actuator is an AC collector motor housed in a plastic housing. Engine control is carried out using the trigger switch with built-in motor speed control. It is possible to  switch the direction of rotation of the spindle to use different tooling.
The machine is equipped with an impact function implemented by using two crowns, providing a reciprocating movement of the spindle during rotation. This feature  increases the efficiency of the machine when drilling hard and brittle materials (brick, concrete, etc.).
The machine is equipped with a side handle that allows you to hold the tool with two hands, providing convenience when working.

OPERATION

ATTENTION!
Always disconnect the power cable from the electrical outlet before preparing for the operation, adjustment, maintenance of power tools.

Installing the side handle

ATTENTION! 
Always use the additional handle supplied with the machine. Losing control of the machine can cause injury.
ATTENTION!
Before work, always check the reliability of the side handle.
Turn side handle 11 (pic. 1) counterclockwise relatively to securing collar by 2..3 turns to loosen it.
Install the side handle on the neck of the machine body behind the chuck. In this case, the chuck 1 (pic. 1)
is not an obstacle to the installation of the handle, if necessary, rotate the side handle another 1..2 turns.
Set the handle to a position that is convenient for operation and tighten the clamp by turning the handle clockwise.

Installation/ withdrawal of the working tool
ATTENTION!
When installing, removing, replacing the tooling, disconnect the power plug. Accidental switching on of the machine when changing accessories may cause significant injury.

Open the chuck by rotating its outer sleeve counterclockwise until the chuck’s cams spread over a distance sufficient to install shank snap. If the chuck is tightened, use the key supplied with the machine. Install shank snap into the chuck. Use tooling with round or hex shank. Never use a snap with an SDS-plus shank, designed for rotary hammers, this shank cannot be centered properly in the three-jaw chuck. Close the chuck by turning the outer sleeve clockwise by hand. Make sure the cams converge evenly and center the tool shank. Tighten the chuck with the supplied key.

ATTENTION!
In order to avoid damage to the engine of the machine and injury, do not tighten or open the drill chuck, turning on the engine while holding the outer sleeve of the chuck with the hand.

Main connection
ATTENTION!
Power tools should only be connected to single-phase AC power, the voltage of which corresponds to the voltage indicated on the rating plate located on the tool housing. If  the rating plate indicates a voltage of 230V, then the power tool can also be switched on to a main with a voltage of 220 V.

When working outdoors use industrial extension cords intended for outdoor use. Do not use homemade extensions. When working outdoors connect power tools to the  power circuit equipped with a differential automatic with a response current of not more than 30 мА, this will reduce the risk of electric shock. When connecting ensure that the insulation of the electrical cable and the power plug of the machine is intact.
Make sure the machine’s power switch is in the “off” position.
This power tool can be connected to power outlets that do not have a protective ground, since it has double insulation (protection class II).

Spindle speed adjustment
Depending on the type of the tooling used, the type of material being processed and the nature of processing, you can choose the optimum spindle speed of the machine.  Adjustment is carried out from the minimum to the maximum value (Section 4, Table 1) by changing the effort of pressing the key 9 (pic. 1) of the switch. You can change the  speed when the engine is running, including under load. Key 9 of the switch can be locked in the “on” position by pressing the fixing button 6 (pic. 1). To unlock key 9,  you need to click on it again. The key stroke of the switch and, accordingly, the maximum spindle speed of the machine can be adjusted by using the setting-ring 10 (pic. 1).  When the switch 9 is locked in the “on” position (pic. 1), the spindle speed of the machine can be adjusted by rotating the setting-ring 10 (pic. 1).

ATTENTION! 
Do not overload the machine operating at reduced speeds. Decreasing the engine rotor speed impairs the cooling of the machine.

Reversing spindle rotation
Spindle rotation direction can be changed from right to left and back if necessary, for example, when using lefthanded drills or grinding tooling. Switching the direction of rotation is carried out using switch 5 (pic. 1), located above the key switch. Switching must be performed only after the engine has completely stopped and when the switch key 9 (pic. 1) is in the “off” position.

ATTENTION!
It is not recommended to use a drilling machine for screwing and unscrewing screws as long work at low rotation may lead to overheating of the engine.

Enable impact mode
To increase the drilling efficiency of hard and brittle materials such as bricks, concrete, etc. the machine is equipped with an impact function. To activate the impact function,  move the mode switch 3 (pic. 1) to the position marked with:
Switching can be done regardless of whether the engine is on or not. To deactivate the impact function move the switch to the position marked:
Please note that it is necessary to apply force of about 200H (20kgs) to the machine in the direction of supply to work effectively in impact mode when drilling brick or  concrete. For efficient drilling of holes with a diameter of more than 10 mm in concrete foundations, it is recommended to use rotary hammers with appropriate accessories.

Using of the drilling depth gauge
When drilling holes to a given depth or a series of holes to the same depth it is convenient to use the included drilling depth gauge. Install the gauge 12 (pic. 1) into the hole  of the bracket of the side handle, previously turn the handle 11 (pic. 1) to 2-3 turnings counter clockwise. Set the gauge overhang so that the difference of the radius between  the gauge and the drill installed in the chuck corresponded to the required hole depth. Lock the gauge, tightening the handle 11 (pic. 1) by turning it clockwise.

Gear speed switching (for item code 26312)
Use the switch 13 (рiс. 1) to switch the gearbox to a higher or lower speed. Switching to reduced speed is recommended when performing work requiring significant torque – drilling with large-diameter drills, mixing mixtures and solutions using mixers, etc. Increased speed will provide effective drilling with drills up to 10 mm in diameter, grinding,  etc. Switching must be done with the engine off, waiting for the spindle full stop.
