2. THE DRILL STOPS BEFORE THE SCREW
IS COMPLETELY TIGHTENED. WHY?
Verify the torque position of the variable clutch, you
can find the variable clutch between the chuck and
the drill body. Position 1 is the lowest torque (screw
driving force) and position is the highest torque
(screw driving force). The position on the drilling
mark is for drill operation. Regulate the variable
clutch to a higher position to reach the best result.
Recharge battery if the drill suddenly stalls
or rotates intermittently.
3. REASONS FOR DIFFERENT CHARGING
TIMES.
Your charge time can be affected by many reasons,
which are not defects in your product. If the battery
pack is only partly discharged it may be re-charged
in less than 1 hour. If the battery pack and ambient
temperature are very cold then recharging may take
1 to 1-1/2 hours. If the battery pack is very hot it
will not re-charge because the internal temperature
safety cutout will prevent it.
If the battery pack is very hot you must remove your
battery pack from the charger and allow your battery
pack to cool first to ambient temperature and then
recharging can be started. If you charge a second
battery pack immediately after the first then the
charger can be overheated. Always allow at least 15
minutes rest between battery pack charging.
4. REASONS FOR DIFFERENT BATTERY
PACK WORKING TIMES.
Charging time issues, as above, and having not
used a battery pack for a prolonged time will reduce
the working life of the battery pack.
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°C and above
30°C as this will affect performance.
