5.2 Replacing Power Line Fuse

If the instrument display fails to light after switching it on, check the power outlet first. If power is
available, and the instrument fails to operate, the power fuse may be open (blown).

5.3 Resetting the dryer thermal overload device

Disconnect the instrument from the power supply before cleaning.
Using a screwdriver, turn the fuse holder to the left
(counterclockwise) and remove the fuse.
Check the condition of the fuse. Replace blown fuse by those of the
same type with the same rated value (5 x 20 mm, T6.3H 250 V).
NOTE: If the fuse is good and power is available at the outlet, the
cord or instrument may be defective. Try a new cord. If this does
not work, the instrument should be sent back for servicing.
The use of a fuse of a different type or with a different value, or
bridging or shunting the fuse is not allowed and can possibly
cause a hazard to your safety and lead to instrument damage!
NOTE: This procedure only applies to units that contain an access
hole to the thermal overload protection device. See illustrations.
If the dryer has overheated and the thermal overload protection
device has responded, it can be reset as follows:
Disconnect the unit from the power supply.
Lift the top cover straight up and remove the access hole cover
from the access hole using a flat head screwdriver.
Reset the overload device with your finger.
Replace the access hole cover and reconnect unit to power supply.
