the Forward and Reverse Switch putting it into the 
required rotation position. Push the trigger and the 
drill will start to rotate (See Fig. C1, C2, C3)
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.  
4. REASONS FOR DIFFERENT BATTERY PACK 
WORKING TIMES
Charging time problems, as above, and having not 
used a Battery Pack for a prolonged time will reduce 
the Battery Pack working time. This can be corrected 
after several charge and discharge operations by 
charging & working with your drill. Heavy working 
conditions such as large screws into hard wood will 
use up the Battery Pack energy faster than lighter 
working conditions. Do not re-charge your Battery 
Pack below 0
o
C and above 45
o
C as this will affect 
performance.
MAINTENANCE
Remove the Battery Pack from the tool before 
carrying out any adjustment, servicing or 
maintenance.
Your power tool requires no additional lubrication 
or maintenance.
There are no user serviceable parts in your power 
tool. Never use water or chemical cleaners to 
clean your power tool. Wipe clean with a dry cloth. 
Always store your power tool in a dry place. Keep 
the motor ventilation slots clean. Keep all working 
controls free of dust. Occasionally you may see 
sparks through the ventilation slots. This is normal 
and will not damage your power tool.
ENVIRONMENTAL 
PROTECTION
Waste electrical products must not be disposed 
of with household waste. Please recycle where 
facilities exist. Check with your local authorities 
or retailer for recycling advice.
