If any adjustments are made to the
engine while the engine is running
(e.g. carburetor), disengage all
clutches and blades. Keep clear
of all moving parts. Be careful
of heated surfaces and muffler.
DECK ADJUSTMENT HANGER ROD
(See figure 26)
If an uneven cut is obtained, the deck may be ad­
justed. A deck adjustment hanger rod and ferrule
is located on the left side of the unit.
To adjust the deck, remove the hairpin cotter
which holds the ferrule into deck bracket. Thread
ferrule upward on the deck adjustment hanger rod
to raise left side of the deck. Thread ferrule
downward to lower left side of deck. Replace the
hairpin cotter after adjustment is made.
CHAIN ADJUSTMENT (See figure 27)
After the first five hours of operation, the initial
slack should be removed from the chain. The
chain should be tight enough so that it deflects
approximately V
2 " when it is depressed with the
thumb.
To Adjust:
The adjusting bolt is located under the frame,
above the cutting deck on the right side of the
mower. See figure 27.
Turn the adjusting bolt clockwise with an open
end wrench until the chain reaches the proper ten­
sion.
NOTE
If the transmission mounting plate
will not slide forward to adjust the
chain tension, it may be necessary
to loosen the four nuts mounting
the transmission to the frame.
NOTE
Deck was removed for photograph­
