7.1
Electronics
Smooth start-up
The electronically controlled smooth start-up
ensures that the machine starts up jolt-free.
Speed control
You can regulate the speed steplessly within the
speed range using the adjusting wheel
[1-17]
(see
Technical data). This enables you to optimise the
cutting speed to suit the surface (see table 1).
Current limiting
Current limiting prevents excessive current con-
sumption under extreme overload, which can
lead to a decrease in the motor speed. The motor
immediately restarts after the load is removed.
Brake
The HK 55EBQ is fitted with an electronic brake.
When the saw is switched off, the saw blade slows
to a stop electronically within approx. 2 seconds.
Restart protection
The integral restart protection prevents the
electric power tool from automatically starting
up again after an interruption in power when the
ON/OFF switch is pressed. In this case the electric
power tool must be switched off and then switched
back on again.
Temperature cut-out
When exceeding a certain engine temperature
level, the machine power supply and speed are
capped. The power tool continues operating at
reduced power to allow the ventilator to cool the
motor rapidly. The power tool resumes to full
performance automatically once the motor has
cooled sufficiently.

Adjusting the cutting angle
The saw table must be on an even surface
when adjusting the cutting angle.
between 0° and 50°:
X
Open knob
[4-2]
.
X
Swivel sawing unit to the desired cutting angle
[4-1]
.
X
Close knob
[4-2]
.
Both positions (0° and 50°) are set at the
factory and can be readjusted by the after-
sales service team.
For angled cuts, the cutting depth is
smaller than the value displayed on the
cutting depth scale.
7.4
Adjust pendulum guard
Risk of injury! Sharp edges!
The pendulum
guard swings back quickly in the event of
sudden release.
The pendulum guard
[1-6]
must only be opened
with the retractor lever
[1-4]
.
