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.
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,
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.
TO SHARPEN BLADE IN A VISE (SEE Fig. L)
1. Be sure the bail handle 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 L-1 in a vise L-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 L-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 Fig. M)
Check balance of blade by placing center hole in blade
M-1 over a nail or screwdriver shank M-2, clamped
horizontally in a vise M-3. If either end of the blade
rotates downward, file that end. Blade is properly
balanced when neither end drops.
BLADE MAINTENANCE (See Fig. N1, N2)
Renew your metal blade after 50 hours mowing or 2
years, whichever 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 (18) and unscrew the blade bolt (17)
counter-clockwise using a spanner wrench, and then
remove blade.
To re-assemble, position the blade (18) with the cutting
edges towards the ground. Then securely tighten the
blade bolt (17).
STORAGE (See Fig. K1, K2)
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 knob, and fold the
upper handle as shown in Fig. K1 & K2.
