GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating oils, etc., come in contact
with plastic parts. Chemicals can damage, weaken or
destroy plastic which can result in serious personal injury.
LINE REPLACEMENT
See Figures 12 - 13.
Use original manufacturer's replacement line for best per-
formance.
 Remove the battery pack.
When using the bump feed trimmer head:
 Rotate the bump knob clockwise as necessary to align the
arrows on the bump knob with the arrows on the string
head housing.
 Cut one piece of trimmer line 10 ft. long. Insert the line
into the eyelet on the string head housing. Push until the
end of the line comes out the other side of the housing.
MAINTENANCE
Pull the line until equal amounts of line appear on both
sides of the housing.
NOTE: Line may jam if more than 10 ft. is loaded.
 Either by hand or using the SPEED WINDER
bump knob clockwise to wind the line on the spool until
approximately 6 in. of line is showing on each side.
NOTE: For best results, after every five to seven revolutions
of the SPEED WINDER
loading results and to help prevent line from tangling.
