(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.
6.MAINTENANCE
Remove the battery pack from the tool before 
carrying out any adjustment, servicing or 
maintenance.
Your 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.
