When only one diode is lit, the battery is discharged and must
be recharged.
INSTALLATION AND REPLACEMENT OF WORKING TOOLS
The rotary hammer drill is designed to operate with working tools
with SDS Plus shanks. Prior to operation clean the rotary hammer
drill and working tools. Use grease and apply thin layer onto shank
of the working tool.
The rotary hammer drill incorporates clic-clic system (which does
not require to pull off the fixing sleeve (2) when installing a working
tool).
• Set the direction selector switch (3) in middle position.
• Insert working tool shank into chuck (1) and slide it to mechanical
stop (it may be necessary to turn the working tool so it can reach
appropriate position) (fig. D).
• Working tool is properly seated if it cannot be removed without
pulling off the fixing sleeve.
• If the sleeve (2) does not return to its default position, remove the
working tool and repeat the whole operation.
High efficiency of the rotary hammer drill operation can be
achieved by using sharp and undamaged working tools.
DEINSTALLATION OF WORKING TOOL
Just after the operation is finished the working tool may be hot.
Avoid direct contact and use appropriate protective gloves. Clean
the working tool after removal.
• Pull the fixing sleeve (2) to the back and hold.
• Remove the working tool with your second hand by pulling it to
the front (fig. D).
OVERLOAD PROTECTION
The rotary hammer drill is equipped with overload protection.
Spindle of the rotary hammer drill stops immediately after working
tool jams, which could overload the power tool.

SWITCHING ON / SWITCHING OFF
Switching on – press the switch button (4).
Switching off – release pressure on the switch button (4).
Rotational speed of the spindle is controlled with pressure on the
switch button (4).
Each time the switch button (4) is pressed, the LED diode (6) lights
up to illuminate the workplace.
LEFT – RIGHT DIRECTION OF ROTATION
Choose direction of rotary hammer spindle rotation with the
selector switch (3).
Clockwise rotation – set the switch (3) to the extreme left position
(fig. E).
Counter-clockwise rotation – move the switch (3) to the extreme
right position.
* In certain cases position of the switch related to rotation may be different than
specified. Please refer to graphic signs placed on the switch or tool body.
Safe position of the direction selector switch (3) is in the middle, it
prevents accidental starting of the power tool.
• When the switch is in this position, the device cannot be started.
• Use this position of the switch to change drills.
• Before starting the tool make sure the position of the direction
selector switch (3) is correct.
Do not change direction of rotation when the spindle of the rotary
hammer drill is rotating. Check if the position of the selector
switch is correct before starting the tool. You should not use
counter clockwise rotation when impact function is on.
OPERATION MODE SWITCH
Rotary hammer drill is equipped with 2-function switch of the
working mode (5). Depending on its setting, a drilling only or impact
drilling is possible (fig. F).
Impact drilling requires slight pressing on the rotary hammer. Too
great pressure would cause unnecessary, excessive load of the
motor. Check technical condition of the working tools regularly.
Sharpen or replace working tools when needed.
Press the switch lock button 'a' prior to change of position of the
working mode switch (5) (fig. F).
Pos. O – drilling with no impact (drill symbol)
Pos I – impact drilling (symbol of a drill and a hammer)
Do not try to change position of the working mode switch when
the rotary hammer motor is operating. Such action may lead to
serious damage of the rotary hammer, or even injury of the user.
DRILLING HOLES
• When drilling a hole with large diameter, it is recommended to
drill smaller hole and then ream it to desired diameter. It prevents
overloading the rotary hammer drill.
• When drilling deep holes drill gradually to smaller depths, then
slide the drill out of the hole to remove chips and dust.
• If a drill jam occurs during drilling, the overload protection will
engage. Turn off the rotary hammer drill immediately to prevent
its damage. Remove jammed drill from the hole.
• Keep the rotary hammer drill in the axis of the hole. Keeping the
drill perpendicular to the surface of the processed material ensures
the most effective operation. If a drill is not kept perpendicular to
the surface during operation, it may get jammed or broken in the
hole, and injure the user.
Long lasting drilling at low rotational speed of the spindle may
cause motor overheating. Long lasting drilling at low rotational
speed of the spindle may cause motor overheating. Do not cover
holes for motor ventilation in the rotary hammer drill body.
IMPACT DRILLING
• Choose appropriate mode of drilling, impact drilling in this case.
• Insert appropriate drill with SDS-Plus shank into the chuck (1).
• To get the best results use high quality drills with sintered carbide
inserts.
• Press the drill against processed material.
• Switch on the rotary hammer drill by pressing the switch button
(4), the power tool mechanism should operate smoothly and the
tool should not bounce on the processed material surface.
• Increase speed when needed by pressing the switch button (4).
OPERATION AND MAINTENANCE
Remove the battery from the device before commencing
any activities related to installation, adjustment, repair or
maintenance.
MAINTENANCE AND STORAGE
• Cleaning the device after each use is recommended.
• Do not use water or any other liquid for cleaning.
• Clean the tool with a dry cloth or blow through with compressed
air at low pressure.
• Do not use any cleaning agents or solvents, they may damage
plastic parts.
• Clean ventilation holes in the motor casing regularly to prevent
device overheating.
• In case of excessive commutator sparking, have the technical
condition of carbon brushes of the motor checked by a qualified
person.
• Always store the tool in a dry place, beyond reach of children.
• Store the device with the battery removed.
