OPERATION
OVERLOAD PROTECTION
When the tool is forced or the motor is overloaded, the tool
will automatically shut off. To reset the tool, release the trigger
and resume operation. If the tool still does not resume opera-
tion, remove and reinsert the battery. Do not force the tool.
LED LIGHT
The LED emits light from the base of the tool when either the
switch trigger or grip light switch is depressed.
If the tool is not in use, the time-out feature will cause the
light to start fading and then shut off.
The LED light illuminates only when there is a charged bat-
tery pack in the tool.
VARIABLE SPEED SWITCH TRIGGER
See Figure 2, page 10.
The variable speed switch trigger delivers higher speed with
increased trigger pressure and lower speed with decreased
trigger pressure.
To turn the tool ON, depress the switch trigger.
To turn the tool OFF, release the switch trigger.
NOTE:
A whistling or ringing noise coming from the switch
during use is a normal part of the switch function.
NOTE:
Running at low speeds under constant usage may
cause the tool to become overheated. If this occurs, cool the
tool by running it without a load and at full speed.
SHOCK ABSORBER
See Figure 2, page 10.
The shock absorber on the rotary hammer reduces vibra-
tion and dampens impact forces making the tool easier to
control during operation.
DIRECTION OF ROTATION SELECTOR
(FORWARD/REVERSE/CENTER LOCK)
See Figure 3, page 11.
Set the direction of rotation selector in the
OFF
(center lock)
position to lock the switch trigger and help prevent accidental
starting when not in use.
Position the direction of rotation selector to the left of the
switch trigger for forward operation. Position the selector to
the right of the switch trigger to reverse the direction.
NOTE:
The tool will not run unless the direction of rotation
selector is pushed fully to the left or right.
NOTICE:
To prevent gear damage, always allow the tool
to come to a complete stop before changing the
direction of rotation.
INSTALLING/REMOVING BATTERY PACK
See Figure 4, page 11.
Lock the switch trigger.
Insert the battery pack into the product as shown.
Make sure the latches on each side of the battery pack
snap into place and the battery pack is secured on the
tool before beginning operation.
Depress the latches to remove the battery pack.
For complete charging instructions, see the operator’s manu-
als for your battery pack and charger.
WARNING:
Battery tools are always in operating condition.
Lock the switch when not in use or carrying at your
side, when installing or removing the battery pack,
and when installing or removing bits.
ADJUSTING THE DEPTH STOP ROD
See Figure 5, page 11.
The depth stop rod helps control the depth of drilled holes.
To adjust the depth stop rod:
Lock the switch trigger by placing the direction of rotation
selector in the center position.
Press the depth stop rod release lever.
Adjust the depth stop rod so that the drill bit extends
beyond the end of the rod to the required drilling depth.
Release the depth stop rod release lever.
NOTE:
When properly installed, the teeth on the depth stop
rod should be aligned with the teeth indicator on the depth
stop rod holder.
INSTALLING AND REMOVING SDS-PLUS BITS
See Figure 6, page 11.
This tool is equipped with an SDS-Plus connection system.
Only use bits designed for use with the SDS-Plus connec-
tion system.
To install bits:
Remove the battery pack.
Clean the bit and grease it with machine grease before
installing it into the chuck.
Insert the bit into the chuck and push the bit until it is
inserted as far as possible into the chuck.
Pull on the bit to make sure it has locked into place.
To remove bits:
Pull back the clamp collar and remove the bit.
NOTE:
When hammer drilling, use only bits with hardened
metal and SDS-Plus shaft.
