Blade Maintenance - Weed Eater PE550 Instruction Manual

SETTING THE EDGING DEPTH
_WARNING:
Never attempt to adjust
the depth adjusting skid when the engine is
running. Always release the throttle trigger,
wait until the blade stops turning, move the
ON/OFF switch to the OFF position, and dis-
connect spark plug before making adjust-
ments. Your edger is equipped with several
edging depths. The depth used will depend
on your personal edging preference and the
condition of the area where the edging opera-
tion is to be done.
NOTE: If the area to be edged has never
been cut or several weeks have passed since
the last cut, the first edging should be done at
no more than half depth.
TO set the depth:
• Move the depth control lever forward for
shallower edging.
• Move the depth control lever backward for
deeper edging.
Depth
Adjusting
When edging, the trigger handle must be
raised until the skid rests on the ground. The
trigger handle must be held in the raised posi-
tion during the entire edging operation to
maintain a consistent edging depth.
DEPTH ADJUSTING SKID
The surface of the depth adjusting skid will
wear over a period of time. This part is revers-
ible to provide a second wear surface.
• Remove the two mounting screws which
hold the skid to the support arm.
• Rotate the skid 180 degrees.
• Reinstall the mounting screws.
EDGING TIPS

the ground.
