e) Do not attach a saw chain woodcarving blade or
toothed saw blade.
Such blades create frequent kickback and loss of
control.
SAFETY WARNINGS SPECIFIC FOR SANDING
OPERATIONS
a) Do not use excessively oversized sanding disc
paper. Follow manufacturers recommendations,
when selecting sanding paper.
Larger sanding paper extending beyond the sanding
pad presents a laceration hazard and may cause
snagging, tearing of the disc or kickback.
SAFETY WARNINGS SPECIFIC FOR
POLISHING OPERATIONS
a) Do not allow any loose portion of the polishing
bonnet or its attachment strings to spin freely.
Tuck away or trim any loose attachment strings.
Loose and spinning attachment strings can entangle

to the power requirements specifi ed on the product
nameplate.
2. Power switch
Ensure that the power switch is in the OFF position. If
the plug is connected to a receptacle while the power
switch is in the ON position, the power tool will start
operating immediately, which could cause a serious

PRACTICAL SANDER POLISHER
APPLICATIONS
1. Sander operation
metal
When utilizing this tool as a disc sander, set the speed
to high (H) for maximum effi ciency.
(1) Do not excessively push the sanding disc against the
surface of the material. Optimum sanding can be
achieved by the weight of the machine alone. Excessive
pressure will reduce the revolving speed of the disc,
creating an unevenly fi nished surface and causing
overload to the motor.
