Operating Instructions

SLIDE ON-OFF SWITCH WITH LOCK

The tool is switched “ON” by the switch button located at the side of the motor housing. The switch can be locked in the “ON” position, a convenience for long grinding operations.

TO TURN THE TOOL “ON” without locking it, slide the switch button forward by applying pressure ONLY at the REAR portion of the button. When pressure is released the switch button will snap to “OFF” position.

TO LOCK THE SWITCH “ON”, slide the switch button forward and press “IN” the FRONT portion.

TO UNLOCK THE SWITCH, simply press and release the REAR portion of the button. Switch is spring loaded and will snap back automatically.

!WARNING Hold the tool with both hands while starting the

tool, since torque from the motor can cause the tool to twist.

Start the tool before applying to work and let the tool come to full speed before contacting the workpiece. Lift the tool from the work before releasing the switch. DO NOT turn the switch “ON” and “OFF” while the tool is under load; this will greatly decrease the switch life.

ELECTRONIC FEEDBACK CIRCUITRY (EFC) The internal electronic feedback system provides a "soft start", which will reduce the

stresses that occur from a high torque start. The system also helps to keep the no load speed virtually constant between no-load and load conditions.

OVERLOAD PROTECTION

Your tool is equipped with overload protection to protect the motor. If the tool stops during operation TURN OFF SWITCH IMMEDIATELY and allow the motor to cool for about 30 seconds by running at no-load. If the overload protection stops the tool repeatedly, excessive force is causing the tool to overload. Don't press so hard and let the tool do the work.

DUST EXTRACTION

!WARNING This tool must only be used with a dust extraction

system. In addition, always wear approved dust mask.

Your tool is equipped with a dust port for dust extraction. To use this feature, attach vacuum hose (optional accessory) to the dust port, and connect the opposite end of the hose to a shop vacuum cleaner.

Always make sure the vacuum cleaner that you use is designed for extraction of masonry dust.

AUXILIARY HANDLE

The auxiliary handle, used to guide and balance the tool can be bolted to either side of the spindle housing depending on personal preference and comfort. Always use the auxiliary handle for maximum control and ease of operation.

Tool Tips

This tool is intended for grinding, deburring and smoothing mainly mineral materials such as, for example, concrete, stone, marble and poured flooring without the use of water. It also can be used for removing protective coating and adhesive residue.

Do not use water or other cooling fluid with this tool for grinding.

Allow the tool to reach full speed before applying it to the workpiece surface.
