MAINTENANCE
WARNING: Disconnect spark plug wire and
ground it against the engine before per­
forming any repairs or maintenance.
CUniNG BLADE
A. Removal for Sharpening or Repiacement
A WARNiNG: Be sure to disconnect and
ground the spark plug wire before work­
ing on the cutting blade to prevent ac­
cidental engine starting. Protect hands by
using heavy gloves or a rag to grasp the
cutting blade.
1 . Remove the large bolt and lock washer which holds
the blade and adapter to the blade spindle. See
figure 16.
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. See figure 16.
B. Sharpening
Remove the cutting blade by following the directions
of the preceding section.
When sharpening the blade, follow the original angle
of grind as a guide. It is extremely important that each
cutting edge receives an equal amount of grinding 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 the blade, 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.
