WARNING
Risk of injury, electric shock
Always pull the mains plug out of the socket be-

fore performing any type of work on the ma-
chine!
7.1 Electronics
Smooth start-up
The electronically controlled smooth start-up en-
sures 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 immedi-
ately 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 automatical-
ly once the motor has cooled sufficiently.
7.2 Adjusting the cutting depth
The cutting depth can be set at 0 – 55 mm.
Press cutting depth adjustment [3-1].

Pull up or push down saw at main handle.

Cutting depth without guide rail/cross cut-
ting guide rail
max. 55 mm
Cutting depth with guide rail/cross cutting
guide rail
+FS
max. 51 mm
7.3 Adjusting the cutting angle

The saw table must be on an even surface when
adjusting the cutting angle.
between 0° and 50°:
Open knob [4-2].

Swivel sawing unit to the desired cutting angle [4-

1].
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 sud-
den release.
The pendulum guard [1-6] must only be opened with
the retractor lever [1-4].

Always pull the mains plug out of the socket be-

fore performing any type of work on the ma-
chine!
CAUTION
Hot and sharp tools
Risk of injury
Do not use insert tools that are blunt or defec-

tive.
Wear protective gloves.

Swivel saw to 0° position before replacing the saw

blade and set maximum cutting depth.
Position saw on motor cover when replacing[5-

2].
Turn lever [5-4] as far as stop.

Open the screw [5-10] using the Allen key[5-3].

