Troubleshooting
Weak Battery Packs
Weak batteries will continue to function but should not be
expected to perform as well. When the appliance is powered
by a battery pack and its charging level falls below 20%, the low
battery indicator isdisplayed.
Battery Pack Protection
To protect the life of the battery pack, the appliance will shut
off when the battery’s charging level becomes too low. If this
happens, connect the TSTAK™ CONNECT RADIO to an outlet
with the AC/DC power adaptor and charge the batterypack.
Music Stops
When dropping the appliance in its vertical position the
battery pack may disconnect from its receptacle. If the music is
operated by the battery pack, the music will stop. To resume,
open the cover and reposition the batterypack.
Lubrication
Your power tool requires no additionallubrication.
Protecting the Environment
Separate collection. Products and batteries marked
with this symbol must not be disposed of with normal
householdwaste.
Products and batteries contain materials that can
be recovered or recycled reducing the demand for raw
materials. Please recycle electrical products and batteries
according to local provisions. Further information is available at
www.2helpU.com.
Rechargeable Battery Pack
This long life battery pack must be recharged when it fails
to produce sufficient power on jobs which were easily done
before. At the end of its technical life, discard it with due care for
our environment:
• Run the battery pack down completely, then remove it from
thetool.
• Li‑Ion cells are recyclable. Take them to your dealer or a
local recycling station. The collected battery packs will be
recycled or disposed ofproperly.
MAINTENANCE
Your power tool has been designed to operate over a long
period of time with a minimum of maintenance. Continuous
satisfactory operation depends upon proper tool care and
regularcleaning.

WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect battery pack
before making any adjustments or removing/
installing attachments or accessories. An accidental
start-up can causeinjury.
The charger and battery pack are notserviceable.
Fast Red Blink
Faulty Battery Packs
This charger will not charge a faulty battery pack. The
charger will indicate faulty battery pack by displaying an
X on the LCD battery image. If this occurs, re‑insert the
battery pack into the charger. If the problem persists,
try a different battery pack to determine if the charger is
working properly. If the new pack charges correctly, then
the original pack is defective and should be returned to a
service center or other collection site for recycling. If the
new battery pack elicits the same trouble indication as the
original, have the charger and the battery pack tested at
an authorized service center.
NOTE: This could also mean a problem with a charger.
