SPECIFICATIONS
ASSEMBLY
WARNING! Wheel guard must be attached when using disc
grinding wheels. Always keep wheel guard between you and
your work while grinding.
WARNING! Before attaching a backing pad be sure its
maximum safe operating speed is not exceeded by the
nameplate speed of the tool.
Wheel guard may not be used for most sanding operations.
Always reinstall wheel guard when converting back to
grinding operations.
WARNING! Always use auxiliary handle for maximum control
over torque reaction or kick-back. Operation of the grinder
without the side handle could cause loss of control of the
grinder, resulting in possible serious personal injury.
WARNING! Do not use water or other cooling fluid with this
tool for cutting.
When using an abrasive cut off wheel, be sure to use only
the special wheel guard designed for use with cut-off wheels.
Never use cut-off wheel for side grinding.
Lock Nut And Backing Flange
Your tool is equipped with a threaded spindle for mounting
accessories. Always use the supplied lock nut (and backing
flange) that has same thread size as spindle.
Mounting The Side Handle
The side handle used to guide and balance the tool can be
threaded into the front housing on either side, and on top of
the tool, depending on personal preference and comfort.
Use the side handle for safe control and ease of operation.
1) Screw the side handle into one of the 3 optional tapped
holes on the gear housing depending on operator.
2) Tighten the side handle securely.
Disc Grinding Wheel Assembly
• Disconnect tool from power source. Be sure that wheel
guard is in place for grinding.
• Thread BACKING FLANGE onto spindle, then place
GRINDING WHEEL on the spindle. Thread on the lock nut
and tighten nut using the supplied lock nut spanner (9), while
holding the spindle lock in. (Fig.1)
• TO REMOVE: Reverse procedure.
• Disconnect tool from power source before attaching cutting
wheel. With cut off wheel guard in place, assemble flange,
cutting wheel and lock nut. When cutting, make only small
passes through workpiece at a time. Be aware that
“Kickback” can occur at any time. Keep both hands on tool
for maximum control. (Fig.2)
Masonry Cutting Wheel Assembly
For cutting masonry materials like brick, tile, stone, etc., it is
best to use a dry diamond cutting wheel. Use only lock nut and
flange with equal diameters.

spindle as far as you can with your fingers. Press in the
spindle lock, then tighten the backing pad securely with the
lock nut spanner (9). (Fig.3)
