MAINTENANCE
WARNING: Stop the mower and remove the
batteries 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 ttings, 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
BATTERIES ARE REMOVED.
Sharpening the blade twice during a mowing season
is usually sufcient 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. M)
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
batteries.
2. Place the mower in stand up storage mode.
BLADE BALANCING (See Fig. N)
Check balance of blade by placing center hole in blade
N-1 over a screwdriver shank N-2, clamped horizontally
in a vise N-3. If either end of the blade rotates
downward, le that end. Blade is properly balanced
when neither end drops.
BLADE MAINTENANCE (See Fig. O1, O2)
Replace your Mower 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.
Make sure batteries are not installed. Wedge a block
of wood between the blade and the mower deck to
prevent the blade from turning and unscrew the Blade
Bolt 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.
