5" Random Orbital Sander
Operator’s Manual GROS2304
WARNING:
Never operate the sander without an abrasive disc
installed, doing so will damage the pad and affect its ability to firmly hold
abrasive discs during use and possibly causing personal injury.
Dust Collect Bag
WARNING:
Never operate this tool without the dust collection bag
installed when using perforated abrasive paper.
The dust collection bag is located in the rear of your sander. As mentioned in the previous section,
sanding dust is drawn up into the holes punched in the abrasive paper, then through the matching
holes in the sanding pad and into the dust bag where it’s collected during sanding operations. As the
dust collection bag fills beyond half full the dust collection system becomes less efficient. Therefore, for
more efficient performance, empty the dust bag when it becomes half full.
To Empty the Dust Collection Bag
• Unplug the sander from the power source.
• Remove the dust bag from its rear mount by gripping the sander with one hand and the dust bag
with your other hand. Then pull the dust bag straight back.
• To empty the bag you simply turn it on end with round mounting tube at the front of the bag pointing
downward and shake the content from the bag into a container.
To Reinstall the Dust Collection Bag:
• Unplug the sander from the power source.
• Insert the mounting tube into the dust exhaust port at the rear of the sander until it is firmly set in
place.
Sanding Operation
Your sander smooths the workpiece surface by the pad moving in tiny circles at high speed. This type
of sanding action called "orbital motion", giving your sander a very fast cutting action for quick removal
of large amounts of stock, especially with the coarser grit abrasive papers. On most sanding jobs,
orbital motion gives you the ability to sand in any direction irrespective of the wood’s grain. However, to
attain a better finish, it is best to sand "with" the grain.
This sander is designed to be held either around the main housing or a palm grip on top of the housing.
During long periods of sanding you may find it helpful to relieve hand fatigue by periodically alternating
your grip between the two holding styles.
NOTE:
When holding the sander in the palm grip style, try positioning your
hand and fingers to minimize covering the upper motor cooling vents
.
To Use the Sander
• Clamp or otherwise secure the workpiece to prevent it from moving while you’re sanding.
• Hold the tool in front and away from you and clear of the workpiece. Start the sander by
pressing the
switch to the "I" (ON) position and let it come up to full speed.
• Slowly lower your sander onto the workpiece, the move the sander in slow forward & backward
strokes. Do not force or push the tool down on the workpiece, the weight of the tool is sufficient
pressure, allowing the motor and abrasive paper to operate at their most efficient speed. Excessive
pressure causes the motor to slow down, preventing the abrasive from cutting effectively and
causes the abrasive to prematurely wear out. When the motor is slowed by excessive pressure the
