Removing and installing the blade
(fig. S, T & U)
Warning! Do not touch the blade before the safety key has
been removed and the blades have come to a complete stop.
Release the bail bar (2) to turn mower off, wait for the
u
blade to stop and remove the safety key (1).
Cut a piece of wood (approximately 50 mm x 100 mm x
u
600 mm long) to use to keep the blade from turning while
removing the flange nut (29).
Turn the mower on its side.
u
Warning! Wear gloves and proper eye protection. Be careful
of the sharp edges of the blade.
Position the wood (28) and remove the flange nut (29)
u
with a 13 mm wrench (fig. S).
Remove the washer (30), blade (31), square blade guide
u
(32) and the fan (33) (fig T). Examine the blade guide (32)
and fan (33) for damage and replace if necessary.
When fitting the blade, make sure that the grass side of the
blade (Indicated by arrows on either end) will face the ground
when the mower is returned to its normal upright position.
Install the fan (33). Be sure to position the fan blades (34)
u
so that they face in towards the mower.
Install the blade guide (32). Be sure to position the 'D'
u
shaped pegs (35) so that they face out, away from the
mower.
Be sure to align the flats on the on the fan (33) and the
u
blade guide (32) with the flats of the shaft.
Fit the blade (31) onto the blade guide (32) with the ar-
u
rows facing outwards.
Position the piece of wood (28) to keep the blade (31)
u
from turning (fig. U).
Install the washer (30) and flange nut (29) then tighten
u
with a 13mm wrench.
Blade sharpening (fig. V)
Keep the blade sharp for best performance. A dull blade does
not cut grass cleanly or mulch properly.
Warning! Always make sure that the safety key is removed.
Warning! Wear proper eye protection while removing, sharp-
ening and installing a 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.
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.
(Original instructions)
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.
Remove the safety key (1).
u
Wipe all exposed parts with a damp cloth.
