Speed regulation:
The speed controller (1.9/2.3) provides infinitely variable
setting between 1800 and 3800 rpm of the speed of the saw
blade. This enables you to optimise the cutting speed to suit
the material.
Constant speed:
The pre-selected speed remains constant whether the machine
is in operation or in neutral position.
Diode display:
- The green diode (2.2) shows the operator that the machine
is in operation.
- The red diode (2.1) shows that the motor is overloaded by
about 70 %. If the motor is thus overloaded for a lengthy
period, it is switched off by the safety electronics.
Our recommendation: If the red diode lights up, lower the
feed power until the red diode goes off again. You are then
working within the allowed load.
Overload protection:
Current limiting prevents permissibly high current con-
sumption under extreme overload. This can lead to a decrease
in the motor speed. The motor immediately restarts after the
load is removed.
Temperature protection:
To prevent overheating, the safety electronics switches the
machine off when it reaches a critical motor temperature.
Let the machine cool down for approx. 3-5 minutes before
using it again. The machine requires less time to cool down if
it is running, i.e. in neutral position.
Note: The lower the AWG number, the stronger the cable.
3 Machine construction
Always disconnect the plug from the power
supply before making any adjustments to the circular saw or
installing or removing any accessory!
3.1 Electronics
The AT 65 E hand-operated circular saw has solid shaft
electronics with the following functions:
Smooth start-up:
The electronically controlled smooth start-up facility enables
start-up of the machine without jerks and requires a lower
start-up current.
No-load speed limitation:
The electronics limit the idling speed in relation to the operating
speed to max. 3800 /min. By this means the saw is rendered
very quiet during idling, ensuring that the gears and the motor
are treated with care.
