5.  Carefully file the cutting edges of the blade 
with a fine tooth file K-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. 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)
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 
(14) and unscrew the blade bolt (13) counter-
clockwise using a spanner wrench, and then 
remove blade. 
To re-assemble, position the blade (14) with 
the cutting edges towards the ground. Then 
securely tighten the blade bolt (13). 
STORAGE: 
(See Fig. N)
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, and 
rotate or fold the upper handle.
