SANDING DISC

Before assembling wire brush to this tool, disconnect from the power source. Wire brushes are equipped with their own threaded hub, simply thread on to spindle. Be sure to seat against shoulder before turning tool “ON”.

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.

!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.
