HINTS FOR OPTIMUM USE
Do not place your hands over the ventilation slots.
Do not exert too much pressure on the tool.
Regularly check the condition of the sanding sheet. Replace when necessary.
Always sand with the grain of the wood.
When sanding new layers of paint before applying another layer, use extra fine grit.
On very uneven surfaces, or when removing layers of paint, start with a coarse grit. On
other surfaces, start with a medium grit. In both cases, gradually change to a fine grit for a
smooth finish.
CAUTION: Respiratory hazard. Never operate this tool for wood sanding unless the
dust canister is in place. Sanding dust exhaust may create a breathing hazard.
WARNING: Fire hazard. Collected sanding dust from sanding surface coatings (polyure

To reduce risk, empty canister frequently and strictly follow sander manual and coating man
ufacturer’s instructions.
WARNING: Fire hazard. When working on metal surfaces, do not use the dust canister
because sparks are generated. Wear safety glasses and a dust mask. Due to the danger
of
fire, do not use your sander to sand magnesium surfaces. Do not use for wet sanding.
MAINTENANCE
Use only mild soap and damp cloth to clean the tool. Never let any liquid get inside the tool;

Stretch sandpaper as tight as possible when clamping.
NOTE: On new tools the sandpaper may be difficult to install because of the stiffness of the
sanding pad. This condition will improve as the pad compresses over time.
