1 Directions for use
The charger ECU 45 has been designed to
charge the battery packs specifi ed under
Chapter 2.
The user will be liable for damage due to
improper use.
For your own safety
• Repairs may only be carried out by quali-
fi ed experts. Warning: ECU 45 charging
device: Even after disconnection from the
mains, there is still a high capacitor volt-
age on the power output component on
the inside of the device.
• Protect equipment against moisture.
• Do not use the charger if the connecting
cable is damaged, unplug immediately
from the main.
• Protect the cable against heat, oil and
sharp edges.
• Never carry the tool by its cable and never
use to the cable to pull the plug out of the
wall socket.
• Do not use defect and damaged battery
packs.
• Only use original Festool battery packs.
Do not use spent and recycled battery
packs. The user shall be liable for dam-
ages if Festool original battery packs are
not used.
• Do not place spent battery packs into
fi re or into domestic waste. Attention:
Festool offers an ecological friendly waste
disposal for used battery packs (refer to
RECYCLING OF BATTERY PACKS).
• Do not open battery packs.
• Do not store battery packs with metal
objects (danger of short circuit).
• No metal objects (metal chips) should
enter the charger at the contact points as
well as through the cooling slits into the
equipment (danger of short circuit).
• Keep out of reach of children.
• Check the tool for damages before use.
Have damaged parts repaired or replaced
by the customer service department.
2 Charge battery pack
All NiCd and NiMH battery packs between 7.2
V and 14.4 V voltage can be charged with the
ECU 45 charger.
The battery type used (NiCd or NiMH) is
detected automatically. Charging is control-
led by a microprocessor.
Warning: If a warm NiMH battery pack
(>37°C) is inserted, charging will only be
carried out at a lower charge current.
In this case the charging time for a battery
pack with 3.0 Ah is around 100 min..
By the infl uence of powerful electromag-
netic perturbations while charging it can be
switched over to conservation charge.
Thereby the charger can not take in a dan-
gerous or unsafe status
The LED (1.10) shows the charge status of
the charger.
LED yellow - steady
= Charger is ready for use.
LED green - fl ashing
= Battery pack being charged.
LED green - steady
= Battery pack fully charged, conservation
charge on.
LED red - fl ashing
= General malfunction, e. g. full contact
not being made, short-circuit, battery pack
faulty.
LED red - steady
= Temperature of battery pack is outside
permissible limit (5° - 45°C).
Charging
Connect charger to mains.
Warning: The line voltage and frequency
must correspond with the data on the rat-
ings plate!
