BLADE REPLACEMENT

The cutting blade is subject to wear and
damage such as nicks and dents. This will not
generally affect its function.
This blade is specially designed to not require
sharpening. Do not attempt to sharpen this
blade. The blade is reversible. If the nicks and
dents are excessive, remove the blade, turn it
around and reinstall. This will provide a fresh
cutting edge. The blades should be replaced
if both sides are worn and damaged. If any
cracks are evident, replace the blade imme-
diately.

CAUTION

: When removing or tighten-

ing the blade nut, always use the method
shown in Fig. 3- SERV & ADJ. The holding
wrench must always be positioned on the nut
behind the cutting blade.

CAUTION

: Do not attempt to sharpen

this blade. Sharpening could damage it and
cause it to break, which may further result in
injury to yourself or a bystander.
To replace the blade, do the following:
• Always wear gloves when handling the

blade.

• Disconnect spark plug wire.
• Remove the 1/2-20 locknut shown in Fig. 3-

SERV & ADJ securing the blade to the
drive shaft.

• Remove the blade.
• Install the new blade and reinstall nut.

Tighten the nut securely.

• Reconnect the spark plug wire.

V-BELT REPLACEMENT

Your Edger/Trimmer is equipped with a V-belt
made of a special compound. If the belt be-
comes worn or breaks, replace it with an
orignal equipment belt as shown in the Repair
Parts section of this manual. Never use a
substitute.
• Disconnect the spark plug wire.
• Put the clutch lever back or up to release the

tension from the belt.

• Remove the two top screws from the engine

pulley cover as shown in Fig 1-SERV&
ADJ
and remove the cover. Make sure you
do not lose the spacer on the rear screw.
