Ariens 911 - Manual (Page 18)

Lubrication and Maintenance (Continued)
A WARNING: Stop engine, wait for
moving parts to stop and remove wire
from spark piug before attempting any
maintenance procedures.
When blade needs sharpening, block blade to
prevent rotation, remove cap screw(s), lock washer(s)
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.
Install blade, lock washer(s) and tighten cap screw(s)
until lock washer is fully compressed (requires 25-30
foot pounds of torque on nuts).
NOTE: The 01172300 mulching blade is the only
blade to be used with the mulchmaster insert dome.
IMPORTANT: If mower is used under sandy soil
conditions, replace blades when air lifts become
eroded through at end.
