Maintenance - GreenWorks EDA75 Manual Del Operador

WARNING:
To prevent serious injury, never perform
maintenance on the unit while it is running. Always turn the
unit off and allow it to cool. Prevent the unit from starting
accidentally: For gas-powered units, disconnect the spark
plug wire. For electric-powered units, disconnect the unit
from the power source. For battery-powered units, remove
the battery.
NOTE: Some maintenance procedures may require special tools or
skills. If you are unsure about these procedures, take the unit to
a qualified service dealer.
REPLACING THE EDGER BLADE
1. Align the output shaft hole with the locking rod slot. Insert the
locking rod through the locking rod slot and into the output shaft
hole (Fig. 7).
2. Keep the locking rod in place by holding it next to the shaft
housing (Fig.8).
3. While holding the locking rod, loosen the lock nut by turning it
clockwise with a 13 mm wrench (Fig. 9).
4. Remove the locking rod. Remove the lock nut, blade retainer
and edger blade (Fig. 10). Keep the lock nut and blade retainer
for installing the new edger blade.
5. Install the new edger blade, blade retainer and lock nut (Fig. 10).
6. Align the output shaft hole with the locking rod slot. Insert the
locking rod through the locking rod slot and into the output shaft
hole (Fig. 7).
7. Keep the locking rod in place by holding it next to the shaft
housing (Fig.8).
8. While holding the locking rod, tighten the lock nut by turning it
counterclockwise (Fig. 9). Make sure that the edger blade stays
flat and centered against the output shaft while tightening the
lock nut.
If you have a torque wrench, tighten the lock nut to 325-335
in.•lbs (37-38 N•m).
If you do not have a torque wrench, tighten the lock nut with a 13
mm wrench, until the lock nut presses against the blade retainer
and the edger blade is snug. Make sure the edger blade is
installed correctly, then rotate the nut an additional 1/4-1/2 turn.
9. Remove the locking rod.
WARNING:
Make sure the blade is flat against the
output shaft after the lock nut is tightened. If the blade is
off-center, the unit will be damaged by vibration, and the
blade may fly off, which can cause serious personal injury.
