Blade sharpening
Keep blade sharp for best mower performance. A dull blade
does not cut grass cleanly. Use proper eye protection while
removing, sharpening, and installing blade. Sharpening the
blade twice during a mowing season is usually sufficient under
normal circumstances.
Sand causes the blade to dull quickly. If your lawn has sandy
soil, more frequent sharpening may be required.
Note: Replace bent or damaged blade immediately.
When sharpening the blade:
u
Make sure blade remains balanced.
u
Sharpen blade at the original cutting angle.
u
Sharpen cutting edges on both ends of blade, removing
equal amounts of material from both ends.
To sharpen blade in a vice (fig. P)
u
Be sure the blade has stopped and the mower is
unplugged before removing the blade.
u
Remove blade from mower. See instructions for removing
and installing blade.
u
Secure blade (11) in a vice (14).
u
Wear proper eye protection and gloves and be careful not
to cut yourself.
Carefully file the cutting edges of the blade with a fine
tooth file (15) or sharpening stone, maintaining the angle
of the original cutting edge. Check balance of blade. See
instructions for blade balancing.
u
Replace blade on mower and tighten securely.
Blade balancing (fig. Q)
Check balance of the blade (11) by placing centre hole in
the blade over a nail or round shank screwdriver, clamped
horizontally in a vice. If either end of the blade rotates
downward, file along the sharp edge of that dropping end.
Blade is properly balanced when neither end drops.
Lubrication
No lubrication is necessary. Do not oil the wheels. They have
plastic bearing surfaces which require no lubrication.
Cleaning
Turn the mower off and let the blade come to a stop. Use only
mild soap and a damp cloth to clean the mower. Clean out any
