• Sanding of lead-based paint is not recommended. See
Precautions To Take When Sanding Paint for additional
information before sanding paint.
• Do not operate the unit without the dust collection bag.
• Clean your tool out periodically.
• Empty dust bag frequently, especially when sanding resin
coated surfaces such as polyurethane, varnish, shellac,
etc. Dispose of coated dust particles according to the finish
manufacturer's guidelines, or place in a metal can with a tight-fitting
metal lid. Remove coated dust particles from the premises daily.
The accumulation of fine sanding dust particles may self ignite and
cause fire.
• Replace a worn or damaged belt when it causes high
tool rpm. High tool rpm caused by a worn out belt may result
in separation of sanding pad from the sander, possibly causing
personal injury. For instructions on replacing the belt, see
Replacing the Sanding Pad and the Belt under Maintenance.
• Air vents often cover moving parts and should be avoided.
Loose clothes, jewelry or long hair can be caught in moving parts.
• An extension cord must have adequate wire size for safety.
An undersized cord will cause a drop in line voltage resulting in loss
of power and overheating. When using more than one extension
to make up the total length, be sure each individual extension
contains at least the minimum wire size. The following table shows
the correct size to use depending on cord length and nameplate
ampere rating. If in doubt, use the next heavier gauge. The smaller
the gauge number, the heavier the cord.
Voltage (Volts) Total length of cord in meters (m)

220–240V 0–15
Rated Ampere Minimal cross-sectional area of the

0–6A 1.0
6–10A 1.0
10–12A 1.5
12–16A 2.5
WARNING: Some dust created by power sanding, sawing,
grinding, drilling, and other construction activities contains chemicals
known to cause cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry
products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do
this type of work. To reduce your exposure to these chemicals: work
in a well ventilated area, and work with approved safety equipment,
such as those dust masks that are specially designed to filter out
microscopic particles.
• Avoid prolonged contact with dust from power sanding,
sawing, grinding, drilling, and other construction activities.
Wear protective clothing and wash exposed areas with soap
and water. Allowing dust to get into your mouth, eyes, or lay on
the skin may promote absorption of harmful chemicals.
WARNING: Use of this tool can generate and/or disburse dust,
which may cause serious and permanent respiratory or other injury.
