PRIOR TO THE OPERATION
The tool is intended to be operated as a hand held tool. It is always recommended that while using the tool, operators stand on a solid floor, in a secure position
with a firm grip and footing. Be aware that the sander can develop a torque reaction.
ATTACHING DISC PADS (See Figure 4.)
3M™ Disc Pads are specially designed to mate to the 3M™ Electric Random Orbital Sander. Improper Disc Pads could cause damage to the tool and workpiece.
1. Turn to tool to "OFF", or disconnected from the 100-130 VAC or 220-240 VAC socket.
2. Secure the Spindle with the Pad Wench provided with the tool, and screw the Disc pad on. Tighten to firm hand-tightness. Do not over tighten.
3. To remove the Disc Pad, insert the Pad Wrench between the Disc Pad and shroud. Secure the Spindle with the Pad Wrench and unscrew the Disc Pad.
"RUN" MODE (See Figures 1 and 3)
Connect the tool to the 100-130 VAC or 220-240 VAC. At this time it is in "Stand-By" Mode. This mode prevents tool from running if the lever is pushed
accidentally.
1. Press the Power ON/OFF switch to turn the tool "ON". The LED display will indicate that the tool is in Run Mode and will respond to pressing the Activation
Lever or the Speed control "+/-" buttons. The speed setting of the tool will be either 10,000 RPM or the most recent speed selected during the previous use if
it has not been disconnected from AC power.
2. Press either the "+" or "-" button once to change the speed in 1000 RPM increments. The LED display will show increasing and decreasing speed settings by
the number of LED segments illuminated.
3. The tool can now be used normally. While in "Run" Mode", the "+" and "-" buttons can be used to raise and lower the speed of the tool at any time.
STARTING AND STOPPING SANDER (Make certain the Disc Pad is secured onto the tool and that it is the proper sized and type.)
1. Ensure the proper abrasive disc is attached to the disc pad.
2. Press either the "+" or "-" button to set the desired speed. Place the tool onto the surface to be sanded. Ensure the abrasive disc is flat on the surface.
3. Press the Activation Lever to start the tool. Release the Lever to stop the tool. Hold the tool firmly to maintain control. Use moderate hand pressure to keep the
abrasive disc engaged on the surface, If the tool seems difficult to control on the sanding surface, use less hand pressure, or raise the speed setting.
MAXIMUM SPEED FUNCTION
The 3M™ Electric Random Orbital Sander has preset Maximum Speeds (4,000 – 10000 RPM).
When the tool is turned "ON", any speed setting will be stored until Power is turned "OFF". When the Power is turned "OFF", the setting will return to 10,000 RPM
when the Power "ON" again.
OVERLOAD PROTECTION SYSTEMS
The 3M Electric Random Orbital Sander has two systems to protect it from overloading and overheating.
Downforce Overload System
The Sander has the ability to monitor and maintain the preset Maximum Speed as user hand pressure increases or decreases during use.
During periods of overly high hand pressure, the tool will flash the LEDs as a Warning to the user. Continuous high hand pressure should be no greater than
approximately 7 lbs (30 N).
