BLADE MAINTENANCE
,_WARNING: The blade will con-
tinue to spin after the engine stops or
after the throttle trigger has been re-
leased. To avoid serious injury, make
sure the blade has stopped coasting
and disconnect the spark plug (or dis-
connect powerhead from power
source) before performing work on the
blade.
,_LWARNING: Always replace a
blade that is bent, warped, cracked,
broken, or damaged in any other way.
Never attempt to straighten and reuse
a damaged blade. Use only specified
replacement blade. Wear protective
gloves when handling or performing
maintenance on the blade to help
avoid injury.
• The blade is reversible. When the
cutting edge on one side becomes
worn, turn the blade over (see
BLADE REPLACEMENT in the SER-
VICE AND ADJUSTMENTS section).
• Check blade for flatness periodically.
Lay the blade on a flat surface to in-
spect for flatness. Throw away a
blade that is not flat.
BLADE REPLACEMENT
,_LWARNING: The blade will con-
tinue to spin after the engine stops or
after the throttle trigger has been re-
leased. To avoid serious injury, make
sure the blade has stopped coasting
and disconnect the spark plug (or dis-
connect powerhead from power
source) before performing work on the
blade.
WARNING: Wear protective
gloves when handling or performing
maintenance on the blade to avoid
injury. The blade is sharp and can cut
you even when it is not moving.
1. To remove the blade, align hole in
the dust cup with the hole in the
side of the gearbox by rotating the
blade.
2. Insert a small screwdriver into
aligned holes. This will keep the
shaft from turning while loosening
the blade nut.
