CUTTING BLADES
A. Removal for Sharpening or Replacement
WARNING: Be sure to disconnect and
ground the spark plug wire and remove
ignition key before working on the cutting
blade to prevent accidental engine start-
ing. Protect hands by using heavy gloves
or a rag to grasp the cutting blades.
1. Remove the large bolt and lock washer which
holds the blade and adapter to the blade spindle.
2. Remove the blade and adapter from the spindle.
3. If the blade or blade adapter needs replacing,
remove the two small bolts, lock washers and
nuts which hold the blade to the adapter.
B. Sharpening
Remove the cutting blades by following the directions
of the preceding section.
When sharpening the blades, follow the original angle
of grind as a guide. It is extremely important that
each cutting edge receives an equal amount of grind-
ing to prevent an unbalanced blade. An unbalanced
blade will cause excessive vibration when rotating at
high speeds, may cause damage to the mower and
could break, causing personal injury.
The blade can be tested for balance by balancing it
on a round shaft screwdriver. Remove metal from the
heavy side until it balances evenly,
NOTE: It is recommended that the blade always be
removed from the adapter for the best test of balance.
C. Reassembly
Before reassembling the blade and the blade adapter
to the unit, lubricate the spindle and the inner surface
of the blade adapter with light oil. Lubricating the bolt
holes, bolts and inner surface of the nuts with light oil
is also recommended. A 4 oz. plastic bottle of light oil
lubricant is available. Order part number 737-0170.
Engine oil may also be used.
When replacing blades, be sure to install the blade
with the side of the blade marked "Bottom" (or with
part number) facing the ground when the mower is in
the operating position.
Blade Mounting Torque
Center Bolt: 450 in. Ibs. rain., 600 in. Ibs.'max.
Blade Adapter Bolts: 200 in. Ibs. rain., 350 in. Ibs. max.
To insure safe operation of your unit, all nuts and bolts
must be checked periodically for correct tightness.
FUEL FILTER

ter. Replace filter whenever contamination or discol-
oration is noticed. Order replacement filter through
