(Original instructions)
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.
Replace bent or damaged blades immediately.
u
When sharpening the blade:
Make sure that the blade remains balanced.
u
Sharpen the blade at the original cutting angle.
u
Sharpen the cutting edges on both ends of the blade,
u
removing equal amounts of material from both ends.
To sharpen a blade in a vice (fig. V)
Release the bail bar (2) to turn the lawnmower off and wait
u
for the blade to come to a complete stop.
Remove the safety key (1) and the battery pack (22) and
u
turn the lawnmower on to its side.
Remove the blade (31) from the mower, see the instruc-
u
tions for removing and installing blades.
Warning! Wear proper eye protection and gloves and be
careful of the sharp edges of the blade.
Put the blade (31) in a vice.
u
Carefully file the cutting edges of the blade with a fine
u
tooth file or a sharpening stone, maintaining the original
cutting edge.
Check the balance of the blade, see the instructions for
u
blade balancing.
Install the blade (31) on the mower and tighten securely,
u
see the instructions for removing and installing blades.
Blade balancing (fig. W)
Check the balance of the blade by putting the centre hole
u
in the blade on to a nail or a round shank screwdriver that
is clamped horizontally in a vice. If either end of the blade
rotates downward, file that end of the blade until the blade
is balanced.
Lubrication
No lubrication is necessary. Do not oil the wheels. They have
plastic bearing surfaces which require no lubrication.
Cleaning
Release the bail bar (2) to turn the lawnmower off and wait
u
for the blade to come to a complete stop.
Remove the safety key (1).
u
Use only mild soap and a damp cloth to clean the mower.
u
Use a blunt tool to clean out any clippings which may have
u
accumulated on the underside of the mower.
After several uses, check all exposed fasteners for tight-
u
ness.
Preventing corrosion
Fertilisers and other garden chemicals contain agents which
greatly accelerate the corrosion of metals. If you mow in areas
where fertilisers or chemicals have been used, the mower
should be cleaned immediately afterward as follows:
Release the bail bar (2) to turn the lawnmower off and wait
u
for the blade to come to a complete stop.
