Turn off the product and remove the battery pack for DC trimmer.

 

Rotate the bump knob clockwise as necessary to align the arrows  on 

the bump knob with the arrows on the trimmer head housing.

 

Insert the trimmer line into the eyelet on the trimmer head housing. 

Push the trimmer line until the end of the line comes out on the 

other side of the housing. Pull the trimmer line until equal amounts 

of line appear on both sides of the housing.

NOTE:

 When replacing the trimmer line, do not insert more than 

548 cm of line. Line may jam if more than 548 cm is loaded.

 

Either by hand or using the speed winder, rotate the bump knob 

clockwise to wind the line on the spool until approximately 15 cm 

of line is showing on each side.

NOTE:

 After every five to seven revolutions of the speed winder,  

pull both line ends outwards to tighten the spool for best loading 

results and to help prevent line from tangling.

 

Push the bump knob down while pulling on line(s) to manually 

advance the line.

INSTALLING THE LINE

For shafts without arbors:

 

Place the spring into the upper housing around the arbor and

underside of the guide with the corresponding holes in the 

spool.

 

Insert the spool into the upper housing and onto the arbor.

 

Secure the spool in place by pressing it firmly into the upper 

housing and installing a bolt (M8) into the opening in the arbor. 

For curved shaft models, install the black bolt and turn clockwise. 

Make sure the bolt is fully screwed into arbor. Do not overtighten. 

For straight shaft models, install the silver bolt and turn 

counterclockwise. Make sure the bolt is fully screwed into arbor. 

Do not overtighten.

 

Align the ribs on the knob with the slots in the spool and place 

the knob onto the spool.

 

Slide lower housing over the knob and onto the upper housing. 

Push together until the tabs in the upper housing snap into the 

slots in the lower housing.
