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 as well as for light
chiseling work. It is also suitable for drilling
without impact in wood, metal, ceramic and
plastic.
1. CHANGING THE DRILL CHUCK (See
Fig. A) (WX330)
• Removing the replacement drill chuck
WARNING: Before removing the
replacement drill chuck, always
remove the tool or bit!
With the drill pointing toward you, grasp the
locking ring (7) of the SDS-plus “quik-change”
chuck and pull forward firmly, then rotate it to
the side. The SDS-plus “quik-change” chuck
will come free.
• Attaching the replacement drill chuck
When mounting the precision keyed chuck,
grasp the precision keyed chuck with the
whole hand, pull it back as far as it will go,
then rotate it to the side until it can clearly
be heard to latch. The precision keyed chuck
locks itself. Check locking by pulling on the
precision keyed chuck. Make replacements in
a corresponding manner.
2. INSERTING AND REMOVING DRILL
BIT IN SDS
Take care that the dust protection cap
(9) 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 (8)
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.
3. MOUNTING OF BIT IN KEYED CHUCK
(WX330/WX330.2)
WARNING: Do not use tools without
SDS-plus for hammer drilling or
chiseling!
Before mounting the drill bit, attaching the 13
mm keyed chuck, insert bit between the chuck
jaws as far as it will go. Ensure drill bit is in
the center of the chuck jaws. Using the chuck
key provided, there are three holes in which
the chuck key should be inserted. Tighten them
equally in turn at each of the three holes, not
just at one hole. Your drill bit is now locked
in the chuck. The bit can be removed by
reversing the above procedure (See Fig. B).
4. INSERTING/REMOVING THE DRILL
CHUCK (See Fig. C)
• Inserting the drill chuck
To work with tools without SDS-plus (e.g.,
drills with cylindrical shafts), a suitable drill
chuck must be used. Insert the adapter (14) of
the drill chuck (13) with a twisting motion into
the SDS-plus chuck (12) until it can be heard to
lock. The adapter locks itself. Check the locking
by pulling on the drill chuck.
• Removing the drill chuck
To remove the drill chuck (13), pull the locking
sleeve (8) to the rear, hold in this position and
remove the drill chuck from the tool holder.
5. ON/OFF SWITCH WITH VARIABLE
SPEED CONTROL
Depress to start and release to stop your tool.
This tool has a variable speed switch (1) that
delivers higher speeds with increased trigger
pressure - speed is controlled by varying the
pressure applied to the switch. (See Fig. D)
6. SWITCH LOCK-ON BUTTON
Depress the on/off switch (1) then the lock
on button (2) (See Fig. D); release the on/off
switch first and the lock-on button second.
Your switch is now locked on for continuous
use. To switch off your tool just depress and
release the on/off switch.
