MAINTENANCE
WARNING: Stop the mower and
remove the Safety Key before
removing the Grass Collection 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 1-866-354-9679
for advice.
BLADE (13) 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:
(See Fig. K)
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.
NOTE: 1. Be sure the mower is turned off and
remove the key.
2. Place the mower in stand up storage mode.
BLADE BALANCING (See Fig. L)
Check balance of blade by placing center hole
in blade L-1 over a nail or screwdriver shank
L-2, clamped horizontally in a vise L-3. If either
end of the blade rotates downward, file that
end. Blade is properly balanced when neither
end drops.

BLADE MAINTENANCE
(See Fig. M1 M2)
Replace your metal Blade (13) 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
and unscrew the Blade Bolt (12) counter-
clockwise using a spanner wrench, and then
remove the Blade.
To re-assemble, position the Blade with the
cutting edges towards the ground. Then
securely tighten the Blade Bolt.
STORAGE: (See Fig. J1 J2)
Stop the mower and always remove the
Safety Key. Clean the exterior of the machine
thoroughly using a soft brush and cloth. Do
not use water, solvents or polishes. Remove
all grass and debris, especially from the
ventilation slots.
Turn the machine on its side and clean the
blade area. If grass cuttings are compacted
in the blade area, remove with a wooden or
plastic implement.
Store the machine in a dry place. Do not place
other objects on top of the machine.
To aid storage, release the Handle knobs (7),
and rotate or fold the Upper Handle.
