Maintenance

WARNING: To avoid serious injury, remove the battery from the tool before performing any maintenance.

1.Keep the air intake slots clean to avoid overheating.

2.Your trimmer line can dry out over time. To keep your line in top condition, store spare pre-wound spools or bulk line in a plastic, sealable bag with a tablespoon of water.

3.Plastic parts may be cleaned by using a mild soap and a damp rag.

4.The line cutter on the edge of the guard can dull over time. It is recommended you periodically touch-up the sharpness of the blade with a file.

PROBLEM

Automatic line feed does not feed more line.

Solution

• Keep the tabs depressed and

remove the spool from the spool

housing in the trimmer head.

• Ensure that the line is not

crisscrossed on the spool as

detailed in figure U. If it is,

unwind the cutting line, then

wind it back on the spool neatly

so that the lines do not cross.

• Inspect tracks at the bottom of

spool for damage. If damaged,

replace spool.

•Read the code on the back of

spool. If it reads “PA66” call

If it reads “ABS” this is not the issue.

• Pull the cutting line until it

protrudes approximately 4-13/16

inches (122mm) from the spool. If

insufficient cutting line is left on the

spool, install a new spool of cutting

line.

• Align the tabs on the spool cap

with the cut outs in the housing.

• Push the spool cap onto the housing

until it snaps securely into place.

• If the cutting line protrudes

beyond the trimming blade, cut

it off so that it just reaches the blade.

If the automatic line feed still does

not work or the spool is jammed, try

the following suggestions:

• Carefully clean the spool and

housing.

• Remove the spool and check if the

lever in the spool housing can

move freely.
