Bolens 132-395A - Manual (Page 17)

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 un­
balanced 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. Make certain
key is in place on the crankshaft.
