AWS-125 MAINTENANCE

DAILY

1. Before daily start-up inspect tool, power cord, GFCI, and Saw Blade, looking for chips

and cracks.

2. If damage has occurred, repair affected areas before use.

3. Connect the tool to the correct power source and test the Ground Fault Circuit Interrupter

(GFCI) before using the tool. Push the red RESET button and conrm that the red run

light is on. Push the yellow TEST button and conrm that the red run light is off, push

the red RESET button to use the tool.

4. After daily use of the tool, clean and blow off the exterior of tool and around air intake

vents to remove any standing water or stone dust on the eld coil, carbon brushes,

and bearings. Failure to do this will shorten the life of your tool, and could void your

warranty.

PERIODIC

Preventive maintenance performed by unauthorized personnel may result in misplacing of

internal wires and/or components which voids the warranty and could cause serious hazards.

We recommend that tool service and repairs not covered in the manual be performed by

an Alpha

Repair Center.

Periodic maintenance is done to check the tool and to minimize down time. These checks

are done based on hours of operation and operating conditions. Operating condition can

vary depending on the work surface and job being performed. If the tool is not used for a

long period of time the carbon brushes should be checked and the commutator cleaned,

before putting the tool back into operation.

BEARINGS AND GEARS

To minimize your tool’s downtime and expensive repairs, it is recommended to send the tool

back to an Alpha

Repair Center after about 300 to 400 hours of operation, or every second

carbon brush change. The bearings should be replaced and the gears should be checked.

If your tool starts to sound different, this could be an indication of a worn bearing. Continuing

to use to use the tool in this condition could result in overheating or motor failure.
