the lawn edge. Press the locating button on the angle adjustment 
knob and simultaneously turn the head of the trimmer 90 
degree.

OPERATING 
WARNING: Do not allow familiarity with this type of product to make 
you careless. Remember that a careless fraction of a second is 
sufficient to inflict serious injury.  
Do not operate a string trimmer in a tree, on a ladder, or on a 
scaffold; this is extremely dangerous.  
Wear non-slip gloves for maximum grip and protection. 
LINE FEEDING 
Your trimmer uses .065” (1.65mm) diameter nylon line to cut grass 
and weeds quickly and easily. In time, the tip of the nylon line will 
become worn and the auto feed mechanism will automatically feed 
and trim a fresh length of line. The cutting line will wear faster if the 
cutting is done along sidewalks or other abrasive surfaces or heavier 
weeds are being cut. The line will extend approximately ¼ in. with 
each stop and start of the switch trigger until the line reaches the 
length of the grass deflector blade. Do not bump unit on ground in 
attempt to feed line or for any other purpose.  
Automatic feed 
With each switching off and on, the line is adjusted out of the spool 
hub. 
NOTE: Frequently switching on and off without reason results in 
increased line wear.  
NOTE: If the cutting line becomes too short during operation due to 
wear, switch the device off and then back on again to extend the 
working length of the cutting line automatically.  
Manual feed 
If your trimmer line hits sharp or abrasive objects, such as stones, 
metal pieces or concrete the trimmer line can be cut too short to 
continue trimming. In this case, you can manually extend the line ( Fig 
10):  
1.  REMOVE THE BATTERY PACK.  
2.  Press the line-feeding button with one hand while pulling the line 
out with the other.  
3.  Press the button repeatedly to release line to the proper length. 
Each press of the button will release approximately 1/4 inch of 
line. (Note: Release only enough line to extend just beyond the 
blade. If too much line is released, the blade will be unable to cut 
it to the correct working length and it may become tangled on the 
rotating shaft.)  
4.  Install the battery pack.  
5.  Restart the trimmer and return to normal operation.
