WARNING: Stop engine, remove key,
wait for moving parts to stop and remove
wire from spark plug before attempting
any maintenance procedures.
CAUTION: Wear of mower blade will
cause structural weakness. DO NOT in­
stall new or replacement vanes on worn
blades.
When blade needs sharpening, block blade to
prevent rotation, remove nut, lock washer and
blade from shaft.
Sharpen both ends of blade at original angle
(25 degrees), removing equal amounts of
material from each end to maintain proper
blade balance. New blades are balanced to
within 1.3 inch ounces at factory. DO NOT
grind around corner at tip of blade. If cutting
edge of blade cannot be sharpened in a
straight line to within 1/8 of an inch of its end,
replace blade with Ariens replacement blade
only. Blades are available through your Ariens
Dealer.
