Extension cable
If an extension cable is required, it must have a
sufficient cross-section so as to prevent an excessive
drop in voltage or overheating. An excessive drop in
voltage reduces the output and can lead to failure of
the motor. The following table shows
you the correct cable diameter as a function of the
cable length for this machine. Use only U.L. and CSA
listed extension cables. Never use two extension
cables together. Instead, use one long one.

To install a sandpaper disc:
1. Unplug the machine.
2. Peel away the worn out sandpaper disc, leaving
the sponge backing pad in place.
3. Carefully center the new sandpaper disc and
press into place. It will be held securely by the
hook and loop backing.
To replace the Hook and Loop Sponge
Pad:
The sponge pad must be perfectly flat to get good
sanding results. If it is deformed or damaged it will
cause very uneven sanding. Always replace it when
damaged. It is hook and loop on both sides, so to
Replace it, peel it away from the hook and loop on
the Sanding Plate Base and, taking great care to
keep it perfectly centered, affix a new one.
The Brush Bristles on the edge of the
Sanding Plate Cover:
The brush bristles on the edge of the Sanding Plate
Cover serve two purposes, they keep the sanding
disc properly aligned with the work surface without
gouging and they also help the efficiency of the dust
collection by the vacuum cleaner. These brush
bristles will wear with continued use.
The Sanding Plate Cover should be replaced when
the bristles are too worn to ensure effective dust
collection and stabilization of the sanding head.
To replace the cover, follow these steps:
Hold the sanding plate in one hand and with the
other, using the L-hex wrench (supplied), first break
free the center bolt clockwise (1/8 turn only!).
Then only use the L-hex wrench to hold the center
bolt from turning and spin off the sanding plate
counterclockwise.
Then, press the cover down against the spring and,
using snap-ring pliers, remove the circlip which
holds the sanding plate cover to the bracket.
