ELECTRIC IMPACT DRILL
EN
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 8 (pic. 1) of the switch. You can change
the speed when the engine is running, including under load. Key 8 of the switch can be locked in the “on” position
by pressing the fixing button 5 (pic. 1). To unlock key 8, 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 limiter 9 (pic. 1). When the switch 8 is locked in the "on" position (pic. 1), the spindle speed
of the machine can be adjusted by rotating the limiter 9 (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 left-
handed drills or grinding tooling. Switching the direction of rotation is carried out using switch 4 (pic. 1), located
above the key switch. Switching must be performed only after the engine has completely stopped and when
the switch key 8 (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 2 (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 supplied
drilling depth gauge. Install the gauge 11 (pic. 1) into the hole of the bracket of the side handle, previously
loosening the mount of the side handle. 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
by tightening the side handle mounting collar by turning the handle clockwise.
