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.

Hold the tool with both

WARNING

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.

CONSTANT RESPONSE CIRCUITRY

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.

SERVICE MINDER™ BRUSHES

Eliminates quess work, stops the tool when

preventive maintenance is required.

abrasive wheels. Always keep wheel guard

between you and your work while grinding.

Position the wheel guard such that the dust

port does not interfere with the On/Off

system. In addition, always wear approved

dust mask.

Your tool is equipped with a dust port for

dust extraction. To use this feature, insert

adapter into dust port (Fig. 2), then insert

vacuum hose (optional accessory) into the

adapter 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.

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.
