MAXIMUM SPEED FUNCTION
The 3M™ Electric Random Orbital Sander has three preset Maximum Speeds (7,000, 9,000 and 10,000/min (RPM)
When the Sander is started after the Power Supply is turned “ON”, the Maximum Speed will be 9,000/min (RPM). The Maximum Speed can be changed at any
time while the Sander is running or when it is stopped and still in “Run” Mode, as long as the Power Supply is turned “ON”.
Any setting for the Maximum Speed will be stored while the Power Supply is turned “ON”. When the Power Supply is turned “OFF”, the setting will return to
9,000/min (RPM) when the Power Supply is turned “ON” again.
MAXIMUM SPEED AND INTERMEDIATE SPEED CONTROL
1.
Maximum Speed is adjusted by pressing the “+” or “-” buttons on the back of the Sander. While the Sander is in “Run” Mode, each touch will raise or lower
the speed to the next setting.
2.
Intermediate speeds between Zero (0)/min (RPM) and the set Maximum Speed can be used with intermediate Lever positions.
OVERLOAD PROTECTION SYSTEMS
The 3M Electric Random Orbital Sander has two systems to protect the motor and circuit board from overloading and overheating.
Downforce Overload System
The Sander has the ability to monitor and maintain the preset Maximum Speed as user downforce increases or decreases during use.
During periods of overly high user downforce, the Sander will fl ash the LED on the back of the tool from Green to Red and cause the motor to slow slightly as a
warning to the user. Continuous downforce should be no greater than approximately 7 lbs (30 N).
If the user continues with overly high downforce, the Sander will change the LED to solid Red and stop. To restart the sander immediately, released the lever and
pressed down again and continue 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 until the internal temperature cools to a level safe for the electronic systems.
Cooling time depends on local conditions. An initial waiting period of 5 minutes is recommended. Repeated overheating will result in longer cool down times.
ATTACHING DISC PADS
3M™ Disc Pads are specially designed to mate to the 3M™ Electric Random Orbital Sander.
1.
Secure the Spindle with the fl at wrench provided with the tool, and screw the Disc pad on. Tighten to fi rm hand-tightness. Do not over tighten.
2.
To remove the Disc Pad, insert the fl at wrench between the Disc Pad and shroud. Secure the Spindle with the fl at wrench and unscrew the Disc pad.
