Maintenance - KRESS KU370.2 Manual

LED indication
The LED will be lit when the switch is
pressed. When the switch is released, the
LED will automatically go out.
The tool and battery are equipped with
automatic power-off protection system.
The LED flickers for 3 seconds and then
goes off, indicating that the protection
system works. At this time, the system
automatically cuts off the power supply
to prolong the battery life. The following
situations may trigger automatic power-off
protection:
• Overload: Tools are overloaded when
they are running, the current is too high.
In this case, release the switch, stop the
operation leading to tool overload, and
restart the switch.
• Overheat: In the case above, if the tool
is not started, the tool and battery may be
overheated. In this case, cool the tool and
battery pack before starting the switch
again.
• Low voltage: The tool does not work
when the remaining capacity is too low.
In this case, dismantle and replace the
battery pack.
Warning: Make sure the reversing
lever is on the left or right, press the
switch and the LED light comes on.
FAQS
1. Why has the switch been pressed and the
machine does not work?
There is a reversing lever at the top of the switch. When it is
in the middle position, the machine will lock the start-stop
switch. Put it where it needs to be turned and press the
button, the machine will start to rotate.
2. Why does the electric drill stop running before
the screw is tightened?
Confirm whether the mode switching ring is on position
, and adjust the torque regulating ring to a higher position.
The tripping torsion corresponding to position 1 is the
smallest, and that corresponding to position 20 is the
largest. Adjust the mode change-over ring to position
for maximum torque (no trip), and you can also adjust the
mechanical shift lever to the low speed (position 1) for
See Figure G greater mechanical transmission torque.
3. Why is the working time of the same battery
pack sometimes long and sometimes short?
As mentioned above, if a battery pack is left unused for
too long, its working time will be shortened. Such situation
will be improved after charging and using for several times.
Under doing heavy work, such as screwing big screw into
hard wood, the battery power will be consumed very fast.
Do not charge in the environment below 0 or above 40°C,
which will also affect the performance of the battery pack.

MAINTENANCE

Be sure to pull out the battery before any repair
work on the machine.
No additional lubrication or special maintenance is needed
for your power tool. Do not use water or chemical detergent
to clean your power tool. Wipe it with a dry cloth. Tools
