OPERATING THE ON/OFF
SWITCH
WARNING:
Do not
operate for long periods at
low speed because excess heat
will be produced internally.
See Fig. F
LED LIGHT INDICATOR (See Fig. F)
To turn on the light, press the on/off switch and make
sure the forward/reverse rotation control is on right/
left position. When you release the on/off switch, the
light will be off.
LED lighting increases visibility-great for dark or
enclosed area. LED is also a battery capacity indicator.
It will flash when power gets low.
The tool and battery pack are equipped with a
protection system. When the LED Light is quickly
flashing and turn off, the system will automatically
cut off power to the tool to extend battery life. The
tool will automatically stop during operation if the
tool and/or battery pack are placed under one of the
following conditions:
• Overloaded:
The tool is operated in a manner that
causes it to draw an abnormally high current. In this
situation, release the Trigger Switch on the tool and
stop the application that caused the tool to become
overloaded. Then pull the Trigger Switch again to
restart.
• Overheated:
Under the condition above, if the
tool does not start, the Tool and Battery Pack are
overheated. In this situation, let the Tool and Battery
Pack cool before pulling the Trigger Switch again.
•
Low battery voltage:
The remaining Battery
capacity is too low and the tool will not operate. In
this situation, remove and recharge the Battery Pack.
PROBLEM SOLUTION
1. WHY DOES THE DRILL NOT TURN ON WHEN
YOU PRESS THE SWITCH?
The Forward and Reverse Switch, which is on top of
the trigger, is positioned in the lock function. Unlock
the Forward and Reverse Switch putting it into the
required rotation position. Push the trigger and the
drill will start to rotate (See Fig.B)
2. THE DRILL STOPS BEFORE THE SCREW IS
COMPLETELY TIGHTENED. WHY?
Verify the torque position of the Torque Adjustment
Ring, you can find the Torque Adjustment Ring
between the Chuck and the drill body. Position
1 is the lowest torque (screw driving force) and
position 18 is the highest torque (screw driving
force). Position is for drill operation. Position
is for hammer drill operation. Regulate the Torque
Adjustment Ring to a higher position to reach the
best result. (See Fig. E1, E2, E3)
3. I CAN NOT FIT THE BATTERY PACK INTO
THE BATTERY CHARGER. WHY?
The battery pack can be inserted into the charger
only in one direction. Turn the battery pack around
until it can be inserted into the slot. The charger LED
indicator should turn on when the battery pack is
charging.
