OPERATING
INSTRUCTIONS
NOTE: Before using the tool, read the
instruction book carefully.
INTENDED USE
The machine is intended for hammer drilling in
concrete, brick and stone. It is also suitable for drilling
without impact in wood, metal, ceramic and plastic.
BEFORE PUTTING INTO OPERATION
A) CHARGING THE BATTERY PACK
The battery pack charger supplied is matched to the
Li-ion battery installed in the machine. Do not use
another battery charger.
The Li-ion battery pack is protected against deep
discharging. When the battery pack is empty, the
machine is switched off by means of a protective
circuit: The chuck no longer rotates.
In a warm environment or after heavy use, the
battery pack may become too hot to permit charging.
Allow time for the battery pack to cool down before
recharging.
When the battery pack is charged for the first time
and after prolonged storage. The battery pack will
accept a 100% charge after several charge and
discharge cycles.
B) TO REMOVE OR INSTALL BATTERY PACK (SEE
FIG. A)
Depress the battery pack release button to release
and slide the battery pack out from your tool. After
recharge, slide it back into your tool. A simple push
and slight pressure will be sufficient.

OPERATION

1. INSERTING AND REMOVING DRILL BIT IN SDS
Take care that the dust protection cap (2) is not
damaged when changing tools.
— INSERTING
Clean and lightly oil the bit before inserting. Insert the
dust-free bit into the bit holder with a twisting motion
until it latches.
The bit locks itself. Check the locking by pulling on
the tool.
— REMOVING
Retract back the bit holder locking sleeve (3) 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. AUXILIARY HANDLE (SEE FIG. B)

desired working position. To clamp the auxiliary
handle rotates the handle clockwise. To loosen the
auxiliary handle, rotate the handle counter-clockwise.
Warning: Always use the auxiliary handle.
3. ADJUSTABLE DEPTH GAUGE(SEE FIG. B)
Loosen the depth gauge by rotating the handle
counter-clockwise. Slide the depth gauge until the
distance between the depth gauge end and the drill
bit end is equal to the depth of hole/screw you wish
to make. Then clamp the depth gauge by rotating the
handle clockwise.

Depress the On/Off switch (5) 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
(5) that delivers higher speeds with increased trigger
pressure or delivers lower speeds with reduced
trigger pressure - speed is controlled by varying the
pressure applied to the switch.
5. SWITCH LOCK (SEE FIG. C)
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.
