— REMOVING (See Fig. B3)
Retract back the bit holder locking sleeve (2) 
and pull out the bit.
WARNING: Your new WORX Rotary 
Hammer Drill generates powerful 
forces to get your job done quickly and 
effectively. These forces may cause 
inferior quality SDS bits to break and jam 
in the chuck, We therefore recommend 
that only high quality SDS bits be used 
with this tool.
2. INSERTING A TOOL INTO CHUCK (13) 
(See Fig. C)
To open the chuck jaws rotate the front section 
of the chuck while holding the rear section. 
Insert the drill bit between the chuck jaws 
and rotate the front section in the opposite 
direction while holding the rear section. 
Ensure that the drill bit is in the center of 
the chuck jaws. Finally, firmly rotate the two 
separate chuck sections in opposite directions. 
Your drill bit is now locked in the chuck.
3. ON/OFF SWITCH (See Fig. D)
Depress the On/Off switch (4) to start and 
release it to stop your tool. 
— ON/OFF SWITCH WITH VARIABLE 
SPEED CONTROL 
Depress the On/Off switch to start and release 
it to stop your tool. This tool has a variable 
speed switch (4) that delivers higher speeds 
with increased trigger pressure - speed is 
controlled by varying the pressure applied to 
the switch.
4. SWITCH LOCK (See Fig. D)
The switch trigger can be locked in the OFF 
position. This helps to reduce the possibility of 
accidental starting when not in use. To lock the 
switch trigger, place the direction of rotation 
control in the center position.
5. FORWARD AND REVERSE ROTATION 
CONTROL (See Fig. D)
With the hammer pointing away from you, push 
the forward/reverse-lever “ 
 “ to the left for 
forward rotation. Push the forward/reverse-lever “ 
 “ to the right for reverse rotation.
WARNING: Never change the 
direction of rotation while the tool 
is rotating, wait until it has stopped.
6. FUNCTION MODE SELECTION 
(See Fig. E)
The operation of the gearbox for each 
application is set with the function mode 
selection switch (8). To change between 
functions, depress the unlocking button 
(15) and rotate the selector to the desired 
operating mode.
For simultaneous 
drilling and impacting 
of concrete or masonry, 
choose the Hammer 
drilling position.
For screw driving, 
drilling into steel, wood 
and plastics choose the 
Rotary drilling position.
WARNING: The operating mode 
selector switch may be actuated 
only at a standstill.
7. LED LIGHT (See Fig. F)
To turn on the light simply press the on/off 
switch. When you release the on/off switch, 
the light will be off. 
LED lighting increases visibility-great for 
dark or enclosed area. LED is also a battery 
capacity indicator. It will flash when power 
gets low.  
8. TEMPERATURE DEPENDENT 
OVERLOAD PROTECTION
When using as intended for, the power tool 
cannot be subject to overload. When the 
load is too high or the allowable battery 
temperature of 75°C is exceeded, the 
electronic control switches off the power 
tool until the temperature is in the optimum 
temperature range again.
9. PROTECTION AGAINST DEEP 
DISCHARGING
The Li-Ion battery is protected against deep
