MAINTENANCE
wARNING: Stop the mower and
remove the safety key before
removing the grass bag.
NOTE:
To ensure long and reliable service,
perform the following maintenance
procedures regularly. Check for obvious
defects such as a loose, dislodged or a
damaged blade, loose fittings, and worn
or damaged components. Check that the
covers and guards are all undamaged and
are correctly attached to mower. Carry out
any necessary maintenance or repairs before
operating mower. If the mower should happen
to fail despite regular maintenance, please call
our customer helpline for advice.
BLADE ShARPENING
KEEP BLADE SHARP FOR BEST MOWER
PERFORMANCE. A DULL BLADE DOES NOT
CUT GRASS CLEANLY OR MULCH PROPERLY.
WEAR PROPER EYE PROTECTION WHILE
REMOVING, SHARPENING, AND INSTALLING
BLADE. ENSURE THAT SAFETY KEY IS
REMOVED.
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 BLADE
IMMEDIATELY.
whEN ShARPENING ThE BLADE:
1. Make sure blade remains balanced.
2. Sharpen blade at the original cutting angle.
3. Sharpen cutting edges on both ends of
blade to keep it balanced, removing equal
amounts of material from both ends.
TO ShARPEN BLADE IN A VISE (See O)
1. Be sure the switch lever is released, the
blade has stopped and the safety key
removed before removing the blade.
2. Remove blade from mower. See
instructions for removing and attaching
blade.
3. Secure blade O-1 in a vise O-2.
4. Wear safety glasses and be careful not to
cut yourself.
5. Carefully file the cutting edges of the blade
with a fine tooth file O-3 or sharpening
stone.
6. Check balance of blade. See instructions for
blade balancing.
7. Replace blade on mower and tighten
securely. Refer to instructions below.
BLADE BALANCING (See P)
Check balance of blade by placing center hole
in blade P-1 over a nail or screwdriver shank
P-2, clamped horizontally in a vise P-3. If either
end of the blade rotates downward, file that
end. Blade is properly balanced when neither
end drops.
BLADE MAINTENANCE (See Q & R)
Renew your metal blade after 50 hours
mowing or 2 years, which ever is the sooner-
regardless of condition.
Follow these procedures to remove and
replace the blade. You will need garden
gloves (not provided) and a spanner wrench
(not provided) to remove the blade. Hold the
blade (R-2) and unscrew the blade nut (R-5)
counterclockwise using a spanner wrench.
Remove blade nut (R-5), square washer (R-4),
insulator washer (R-3), and blade (R-2).
To re-assemble, first position the blade
with the cutting edges towards the ground.
Assemble the components.
Ensure that the edges of the insulator washer
hook over the edge of the blade. Align the flats
on the square washer (R-4) with the flats on
the shaft.
Then securely tighten the blade nut.
NOTE:
If the blade and insulator washer (R-3)
are cracked or damaged, replace with new
ones.
