HOW TO REPLACE THE BLADE
The blade is subject to wear and damage, such as nicks
and dents. This will not generally affect its function.
The blade is designed to not require sharpening. Do
not attempt to sharpen the blade. The blade is also
reversible. If nicks or dents are excessive, remove
the blade and turn it around. This will provide a fresh
cutting edge. Replace the blade if both sides are worn
or damaged.
MAINTENANCE
To replace the blade, follow the steps below.
(Figure 18A & 18B)
1. Disconnect the spark plug wire from the spark plug.
2. Remove blade cover by undoing the 3 wingnuts
(Fig 18A).
3. Remove blade locknut that holds the blade to the
drive shaft. (Fig 18B)
4. Remove the blade.
5. Install a new blade and blade locknut. Tighten the
blade locknut to a torque of 40-45 foot-pounds
[54-61 Nm].
6. Refit blade cover.
STORAGE
NOTE: A yearly checkup or tune-up at an authorised
service centre will make sure that the edger will
provide maximum performance for the next season.
When the edger is put in storage for thirty days or
more, the following steps should be followed to make
sure the edger is in good condition the next season.
1. Let the engine run until it is out of petrol.
2. Remove the spark plug from the cylinder. Pour few
drops of oil into the cylinder. Slowly pull the recoil-
start grip so that the oil will protect the cylinder.
Install a new spark plug in the cylinder. Pull starter
handle slowly a few times to distribute oil.
3. Clean the dirt and debris from the cylinder cooling
fins and the engine housing.
4. Completely clean the edger. Remove all dirt,
grease,leaves, etc.
5. Check the edger for worn or damaged parts. Have
damaged parts replaced if necessary.
6. Tighten all loose hardware.
7. Apply lubrication as directed in Maintenance section.
8. Put the unit in a building that has good ventilation.
9. When engine completely cold, Cover the edger
with a suitable protective cover that does not retain
moisture. Do not use plastic. Plastic cannot breathe
which allows condensation to form and will cause
your unit to rust.
WARNING
Do not sharpen the blade. Sharpening can
damage the blade and cause it to break, which
can cause injury to you or to others.
WARNING
To remove or tighten the blade locknut, always use
the method shown in Figure 18B. Always position
the holding wrench on the nut behind the blade.
WARNING
Never store the edger indoors with fuel in the
fuel tank. Never store in an enclosed, poorly
ventilated area where fumes could reach an open
flame, a spark or a pilot light as on a furnace,
water heater or clothes dryer. Allow engine to
cool before storing unit.
WARNING
Do not remove petrol while inside a building,
near a fire, or while you smoke. Petrol fumes can
cause an explosion or a fire.
