Operation
Connecting to Power Supply

120 V outlet using a heavy-duty outdoor extension power 
cord.

the hole in the handle and around the cord restraint hook, 
then connect the extension cord to the appliance cord 
(Fig. 31).
Starting the Grass Trimmer
Before you start the grass trimmer, make sure the trimmer is 
not contacting any object.
1.  To turn the grass trimmer ON, press and hold the safety 
lock button with your thumb, then squeeze the ON/OFF 
trigger switch with your ngers. Once the machine powers 
on, you can release the safety button and proceed with 
operation (Fig. 32).
Trimming
• Wear non-slip gloves for maximum grip and protection.
• For the best cutting action against walls, fences, and in high 
grass, move the grass trimmer slowly so grass is cut with 
the tip of the high speed nylon line.
• Avoid dragging the grass trimmer and string spool hub in 
contact with the ground.
• Trim only when grass and weeds are dry.
NOTE: As the weather becomes cooler, the tendency for the 
nylon line to break becomes greater. DO NOT USE WHEN 
TEMPERATURE IS BELOW 50ºF (10ºC).
• Cut tall grass from top down. This will prevent grass from 
wrapping around the shaft housing and string head which 
may cause damage from overheating. 
• If grass becomes wrapped around the string head:  
– Stop the grass trimmer. 
– Unplug the grass trimmer. 
– Remove the grass.
• Hold the grass trimmer with your right hand on the rear 
handle and your left hand on the front auxiliary handle. The 
grass trimmer should be held at a comfortable position with 
the rear handle about hip height.
mWARNING! Always hold the trimmer away from 
body. Any contact with the grass trimmer cutting head while 
operating can result in serious personal injury.
• The life of your nylon line is dependent upon following 
instructions for proper use, as well as what is being cut, and 
where the cutting is being done.
