2. Loosen the 1/2-13" hex nut (1). If the

blade height is lower than the height of

cut knob, loosen the 1/2-13 x 1.75" (2)

bolt which runs through the height of cut

rotation adjustment weldment (3). If the

blade height is higher than the height of

cut knob, tighten the 1/2-13 x 1.75" bolt

which runs through the height of cut

rotation adjustment weldment.

3. Tighten the 1/2-13" hex nut back down

to lock it into position.

4. Raise the deck back to the transport

height and remove the blocks from

below the deck. Measure the blade

height again to ensure it now matches

the height on the dial. If not, repeat until

the two heights are synchronized.

DRIVE ADJUSTMENTS

Steering and motion controls should be

uniform during forward and reverse motions.

The steering control levers should always

return to neutral when released from the

reverse position.

AIR CLEANER SERVICE

(Figure 24)

IMPORTANT: To prevent excessive engine

wear, do not run the engine without the air

cleaner installed.

IMPORTANT: The engine is air cooled and

requires a large amount of air intake when

running. Reduced air intake can cause

overheating. Always keep air intake screen

and cooling fins clean. Always keep the

covers and screens in place.

The Unloader Valve (1) will allow for the

removal of fine dirt and dust from the canister

body (3) without disassembly. While in

operation, this valve will suck closed at 1/3 to

1/2 throttle.

• With the engine shut off, squeeze the

valve by hand to release dust and

debris.

• In very dusty operating conditions, the

valve may have to be opened every 2

to 3 hours.

Remove the air cleaner cover and make a

general inspection of the entire assembly. If it

is unusually dirty or if dirt build-up is easily

visible on the inside of the canister body, the

entire assembly, including the inlet hose,

must be removed from the carburetor and

engine.

With the air cleaner removed from the engine,

and with the cartridges and gaskets removed,

wash the hard parts with cleaning solvent and

blow them dry with compressed air. DO NOT

wash the air cleaner cartridges.

NOTE: If canister gaskets are broken or

missing, BOTH air cleaner elements MUST

be replaced.

Inspect and clean the primary air cleaner

cartridge (5) assembly every 25 hours.

Replace the paper element yearly or every

250 hours, whichever comes first.

The outer cartridge is cleaned by rolling and

“tapping” it on a hard surface. If the paper

pleats are punctured or torn, the element

must be replaced.

CAUTION: Stop the engine, put

the steering control levers in the

park position and remove the key

from the ignition before

performing any maintenance or

repairs on this unit.

CAUTION: Touching hot surfaces

can burn skin. The engine and

components will be hot after the

unit has been running. Allow the

engine and components to cool

before servicing the unit.
