Problem Solution; Maintenance - Yamato CD 12 L Instruction Manual

PROBLEM SOLUTION

1. WHY DOES THE DRILL NOT TURN ON WHEN YOU PRESS THE SWITCH?
The forward/reverse rotation control, which is on top of the trigger, is positioned in the lock function.
Unlock the forward/reverse rotation control by putting it into the required rotation position. Push the
trigger and the drill will start to rotate.
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 16 is the
highest torque (screw driving force). Position 17 is for drill operation. Regulate the variable clutch to
a higher position to reach the best result.
3. I CANNOT FIT THE BATTERY CHARGER. WHY?
The battery can be inserted into the charger only in one direction. Turn the battery around until it
can be inserted into the slot.
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 50°C as this will affect performance.
5. HOT BATTERY PACK PROTECTION
The normal charging temperature is between 0°C and 50°C. When the battery pack is too hot, it
automatically starts a HOT battery pack delay, and suspends charging until it has reached the
correct temperature. The charging process will then automatically begin.
6. BATTER PACK OVERLOAD AND LOW-VOLTAGE PROTECTION
When max. allowable battery current is exceeded during working, the overload protection is
activated to protect the battery against overheating. When the battery is under normal voltage
during working, the power tool will cease to operate.

MAINTENANCE
