and abrasive material can wear away the metal
that connects the flat and curved parts of the
blade, check blade before using the mower. If a
slot or wear is noticed, (Fig. 22B & C), replace
blade. Refer to step 5.
6.
REMOVING BLADE—Grasp end of blade
using a rag or thickly padded glove. Remove (2)
blade nuts, anti-scalp cup, accelerator, and blade
(Fig. 21).
Note:
For best performance, install new blade
before cutting season begins. During
the year, file down small nicks to
maintain the cutting edge.
7.
SHARPENING BLADE—Using a file, sharpen
top side of blade (side facing mower housing)
and maintain original cutting angle (Fig. 23).
The blade will remain balanced if the same
amount of material is removed from both cutting
edges.
POTENTIAL HAZARD
•
A worn or damaged blade could break and
a piece of blade could be thrown in
operator’s or bystander’s direction.
WHAT CAN HAPPEN
•
A thrown piece of blade could cause serious
personal injury or death to operator or
bystanders.
HOW TO AVOID THE HAZARD
•
Inspect blade periodically for wear or
damage.
•
Replace a worn or damaged blade.
IMPORTANT: Check balance of blade by putting
it on a blade balancer. An inexpensive balancer
can be purchased at a hardware store. A balanced
blade will stay in a horizontal position and an
unbalanced blade will settle to the heavy side. If
the blade is not balanced, file more metal off
cutting edge on heavy end of blade.
8.
Install sharp, balanced blade, accelerator,
anti-scalp cup, and (2) blade nuts. Sail part of
blade must point toward top of mower housing
to assure correct installation. Tighten the blade
nuts to 15-27 ft-lb (20-37 N
m).
POTENTIAL HAZARD
•
Operating mower without accelerator in
place could cause blade to flex, bend or
break.
WHAT CAN HAPPEN
•
A broken blade could cause serious injury
or death to operator or bystanders.
HOW TO AVOID THE HAZARD
•
Do not operate mower without accelerator.
Lubrication
After every 25 operating hours or when season ends,
front and rear wheels must be lubricated.
1.
Apply 2 or 3 drops of light oil on inside and
outside of all wheel bolts. Spin wheels to
distribute oil into bushings. Wipe up excess oil.
2.
Move rear wheel height-of-cut levers to “C”
setting. Wipe grease fittings with clean rag.
Install grease gun onto fitting and gently apply
two or three pumps of #2 Multi–Purpose
Lithium Base Grease (Fig. 24). Excess pressure
may damage seals and prevent the free wheel
clutch from operating properly.
Cleaning
Underside of Mower Housing
To ensure best performance, keep underside of mower
housing clean. Be especially careful to keep kickers
free of debris (Fig. 25).
Washing Method
Whenever the underside of the mower requires
cleaning, follow this procedure for washing debris out
from underside of deck.
