Extension Cord
If an extension cord is required, it must have suffi-
cient cross-section to prevent overheating or an ex-
cessive drop in voltage. An excessive drop in voltage
reduces the output and can lead to failure of the
motor. The table below shows you the correct cord
diameter as a function of the cord length for this
power tool.
Use only U.L. and CSA listed extension cords.
Never use two extension cords together. Instead,
use one long one.
L
The lower the AWG number, the stronger the
cord.
Electronics
Consider the pictures on the fold-out page.
The machine features full-wave phase control elec-
tronics with the following features:
Smooth start-up
The electronically controlled smooth start-up en-
sures that the machine starts up jolt-free.
Speed control
The available speed when the ON/OFF switch
[1-4]
is pressed down fully can be set
[1-3]
between 600
and 1400 rpm (RAP 150-14) or 900 and 2100 rpm
(RAP 150-21) using the adjusting wheel. This en-
ables you to optimise the cutting speed to suit the
surface (see table).
L
The power tool is fitted with a variable speed
trigger: Pressing the ON/OFF switch harder in-
creases the speed.
Constant speed
The preselected motor speed is maintained on a
constant level. Electronic controls ensure a steady
cutting speed even when operating under different
loads.
Temperature cut-out
The machine power supply is limited and the speed
reduced if the motor exceeds a certain tempera-
ture. The machine continues operating at reduced
power to allow the ventilator to cool the motor rap-
idly. The machine starts up again automatically
once the motor is cooled down sufficiently.
Electric current limit
AC limiting prevents excessive current consump-
tion under extreme overload, which can lead to a
decrease in the motor speed. The motor immedi-
ately restarts after the load is removed.
Settings
Attaching polishing pads
Only use polishing pads that are suitable for the
maximum speed specified.
The polishing pads M 14 are fitted with a thread M
