MAXIMUM SPEED FUNCTION
This Electric Random Orbital Sander has nine preset Maximum Speeds (2,000-10,000 RPM.)
The original star�ng speed se�ng is not the maximum speed when the tool was shipped out
from the manufacturer.
When the Sander is started a�er the Power Supply is turned “
ON
”.
The Maximum Speed can be changed at any �me while the Sander is running or when it is
stopped and s�ll in “
Run
” Mode, as long as the Power Supply is turned “
ON
”.
Any se�ng for the Maximum Speed will be stored while the Power Supply is turned “
ON
”.
When the Power Supply is turned “
OFF
”, the se�ng will be kept at the last �me you used
when the Power Supply is turned “
ON
” again.
MAXIMUM SPEED AND INTERMEDIATE SPEED CONTROL
1. Maximum Speed is adjusted by pressing the “
+
” or “
—
” bu�ons on the back of the Sander.
While the Sander is in “
Run
” Mode, each touch will raise or lower the speed to the next se�ng.
2. In the default mode the speed can be adjusted linearly by adjus�ng the posi�on of the lever.
SOFT START FUNCTION
The sander has the so� start func�on that prevents gouging of the work surface.
OVERLOAD PROTECTION SYSTEMS
The Sander is equipped with Downforce Overload System.
During periods of overly high user downforce, the sander LED will flash“red” color and cause
the motor to slow slightly as a warning to the user, and to maintain the most efficiency spinning
power under the condi�on of overload.
Con�nuous downforce should be no greater than approximately 3 Kg.
If the user con�nues with overly high downforce greater than 3 Kg, the sander will change
the LED flashes“red and green” alternately and stop.
Downforce Overload System
The sander is equipped with downforce overload system.
During periods of overly high user downforce, the LED indicator shows “ flash red ” color and
cause the motor to slow slightly as a warning to the user. Con�nuous downforce should be no
greater than approximately 3 kg.
If the user con�nues with overly high downforce greater than 3 Kg, the sander will change
the LED flashes“red and green” alternately and stop.
To restart the sander immediately, released the lever and pressed down again and con�nue sanding.
Repeated overloading will result in frequent motor stops and increased tool temperature.
Temperature Overheat System
The Sander has the ability to monitor temperature of the internal electronic systems, and can shut
the tool down when temperature reach damaging levels.
During periods that result in high internal temperature, the Sander will shut down if the
temperature reaches a damaging level. The Sander will not be able to be restarted un�l the
internal temperature cools to a level safe for the electronic systems.
Cooling �me depends on local condi�ons. An ini�al wai�ng period of 5 minutes is recommended.
Repeated overhea�ng will result in longer cool down �mes.
