Discharging the battery
Not only charging batteries is important, discharging is of equal importance or even
greater importance.
• When the battery is charged the cordless drill has to be used until you start noticing that the
power of the drill is diminishing and that the maximum rotational speed is not reached.
• The battery is almost discharged now. Only now you can start charging the battery.
• Charging the battery while it is still charged for say one-third of capacity, the so-called
‘memory effect’can occur. Since during charging only the discharged part of the battery
capacity of the battery is being charged now, the battery can start crystallizing in the one-
third that is still charged. This part of the battery capacity can never be used afterwards.
• Do not discharge the battery to the minimum. As soon as you notice that the power or the
maximum rotational speed is diminishing, you have to charge the battery. When you
proceed using the drill and the battery becomes fully discharged, the so-called ‘switch of
poles effect’can occur. The polarity of the battery poles will be switched: the ‘+’will become
‘-‘ and the ‘-‘ will become the ‘+’. Once this has occurred the polarity will remain switched
during loading and this will damage the battery irreparable.
When the cordless drill is not being used over a longer period of time, the battery
has to be charged fully first. The battery has to be stored in charged condition.
5. SERVICE & MAINTENANCE
Make sure that the machine is not live when carrying out maintenance work on the
motor.
The Ferm machines have been designed to operate over a long period of time with a minimum
of maintenance. Continuous satisfactory operation depends upon proper machine care and
regular cleaning.
Cleaning
Keep the ventilation slots of the machine clean to prevent overheating of the engine.
Regularly clean the machine housing with a soft cloth, preferably after each use. Keep the
ventilation slots free from dust and dirt.
If the dirt does not come off use a soft cloth moistened with soapy water. Never use solvents
such as petrol, alcohol, ammonia water, etc. These solvents may damage the plastic parts.
Lubrication
The machine requiers no additional lubrication.
