MOTOR SAFETY PROTECTION

IMPORTANT: To avoid motor damage, this motor should be blown out or vacuumed frequently to keep 
dust from interfering with normal motor ventilation.

1.  

Connect this tool to a power source with the appropriate voltage for your model.

2.  

If the motor won’t start, turn the switch “OFF” immediately and unplug the tool.

3.  

If the motor suddenly stalls while milling, release the trigger switch and unplug the tool.  The motor may 

now be restarted. 

4.  Fuses may "blow" or circuit breakers may trip frequently for the following reasons:

a.  Motor Is Overloaded - Overloading can occur if you make too many start/stops in a short time.
b.  Line voltages should not be more than 10% above or below the nameplate voltage. For heavy loads, 

however, the voltage at motor terminals must equal the voltage specified for your model. Improper 
or dull milling head is being used.

5.  Most motor troubles may be traced to loose or incorrect connections, overload, low voltage, (such as 

small size wire in the supply circuit) or to an overly long supply circuit wire. Always check the connections, 
the load and the supply circuit whenever motor doesn’t work well. Check wire sizes and length with the 
Wire Size Chart. 

UNPACKING

WARNING: To reduce the risk of injury from unexpected starting or electrical shock, do not plug the 
power cord into a power source outlet during unpacking and assembly. The cord must remain 
unplugged whenever you are working on the tool.
Your tool is shipped complete in one box.

Remove the tool and all loose parts from the carton. Place all parts on a secure, stationary work surface and 
look the machine over carefully.
