To attach the battery pack:
Align the raised rib on the battery pack with the
grooves of the tool, and then slide the battery pack
onto the tool.
To detach the battery pack:
Depress the battery-release button, located on the
front of the battery pack, to release the battery pack.
Pull the battery pack out and remove it from the tool.
NOTICE: When placing the battery pack on the tool,
be sure that the raised rib on battery pack aligns with
the groove inside the tool and that the latches snap
into place properly. Improper attachment of the
battery pack can cause damage to internal
components.
Battery tools are always in
operating condition. Therefore, the
direction-of-rotation (forward/center-lock/reverse)
selector should always be locked in the center
position when the tool is not in use or when carrying
it at your side.
DIRECTION-OF-ROTATION
(FORWARD/CENTER-LOCK/REVERSE)
SELECTOR
See Fig. 5
After tool use, lock the direction-of-
rotation selector in the
“
OFF
”
position (center-lock) to help prevent accidental
starts and possible injury.
Your tool is equipped with a direction-of-rotation
selector, located above the variable-speed trigger
switch. This selector is designed to change the
direction of rotation of the bit and to lock the
variable-speed trigger switch in the
“
OFF
”
(center-
lock) position.
a.
Position the direction-of-rotation selector to the
far right of the tool for forward rotation.
b.
Position the direction-of-rotation selector to the
far left of the tool for reverse rotation.
c.
Position the switch in the
“
OFF
”
(center-lock)
position helps reduce the possibility of accidental
starting when not in use.
NOTICE: To prevent gear damage, always allow the
hammer drill to come to a complete stop before
changing the direction of rotation.
NOTICE: The hammer drill will not run unless the
direction-of-rotation selector is engaged fully to the
left or right.
VARIABLE-SPEED TRIGGER SWITCH
See Fig. 6
Your tool is equipped with a variable-speed trigger
switch. The tool can be turned
“
ON
”
or
“
OFF
”
by
depressing or releasing the variable- speed trigger
switch.
The variable-speed trigger switch delivers higher
speed with increased trigger pressure and lower
speed with decreased trigger pressure.
AUXILIARY HANDLE
See Fig. 7
Secure the auxiliary handle onto the hammer drill
before working. To clamp the auxiliary handle, rotate
the handle clockwise. To loosen the auxiliary handle,
rotate the handle anti- clockwise.
This tool generates high levels of
torque. Never operate the product
without the auxiliary handle to avoid accidents and
injury!
Always ensure that the auxiliary handle is attached
and secured correctly before operation! The auxiliary
handle provides better control of the tool in case of
sudden jams during use when considerable forces are
released!
TWO-SPEED GEARBOX SWITCH
See Fig. 8
Your tool is equipped with a two-speed gearbox
designed for operating at low (L) or high (H) speeds.
A slide switch is located on the top of the tool to
select either low (L) or high (H) speed.
Low (L) speed provides higher torque and slower
speeds for heavy-duty work or for driving screws,
drilling large diameters, or tapping threads. Use Low
(L) speed for starting holes without a center punch,
drilling metals or plastic, drilling ceramics, or in
applications requiring a higher torque.
High (H) speed provides lower torque and faster
speeds for hammer drilling or lighter drilling work.
High speed is better for drilling wood and wood
composites and for using abrasive and polishing
accessories.
NOTICE: To prevent gear damage, always allow the
tool to come to a complete stop before changing
between high speed and low speed.
FUNCTION SELECTOR AND TORQUE-
ADJUSTMENT RING
See Fig. 9
Your tool is equipped with a function selector for
various applications. Move the selector depending on
the requirements of your task.
Screw-driving position and Torque-
adjustment setting
See Fig. 9
a
Your tool also features 20 clutch settings for the
screw-driving position
“
”
. Output torque will
increase as the clutch ring is rotated from 1 to 20.
When driving a screw, first try torque position 1
and increase until the desired torque is reached.
The proper setting depends on the job and the type
of bit, fastener, and material you will be using. In
general, use greater torque for larger screws. If the
torque is too high, the screws may be damaged or
broken. For delicate operations, such as removing a
partially stripped screw, use a low torque setting.
