direction until it stops, it will shut off the flow of
fuel to the engine. When turned in a counter
-
clockwise direction it will open and allow fuel to
flow to the engine. Close this valve if you are not
going to run the mower for a period of 30 min
-
utes or more to prevent flooding the engine.

Seat Adjustment Lever:
The Seat Adjustment
Lever is located beneath the seat. The Seat
Adjustment Lever is used to move the seat for
-
ward and backward. To place the seat in the
desired position pull the seat adjustment lever to
the left then push the seat forward or back to the
desired position. Release the lever so the seat
will lock in place.

Digital Tachometer and Hour Meter:
(See Fig-
ure 1) Located on the right side of the mower in
front of the ignition switch. When the machine is
running the tachometer displays engine rpm.
When the machine is off the tachometer dis
-
plays running time.
10.
Choke Lever:
(See Figure 1) The Choke Lever
is located on the left instrument panel next to the
seat. The Choke Lever is operated manually.
Having the Choke Lever in the ON position helps
the engine to start during initial start-up. During
normal operation the Choke Lever should be in
the OFF position.
Note: The Tanks equipped with E.F.I. do not
have a choke control.
Note: There will be a flashing “LUBE” for
each recommended lubrication interval. There
is a flashing “OIL” at each recommended
engine oil and filter change.
C.Initial Adjustments
1. Check the fluid levels and tires:
Note: These checks should be made daily,
before starting the engine.
a. Fuel: Using a good grade of unleaded, reg-
ular gasoline (for a gasoline engine), fill the
fuel tank (beside the engine on the left or
right side of the mower). When the fuel
reaches one inch from the top of the tank,
stop. DO NOT OVERFILL. Space must be
left for expansion.
b. Engine Oil: (Filled at the factory before
shipment.) Pull out the oil dipstick, wipe it
off and reinsert it. Pull it out again and read
the oil level. If it is below the operating
range, add oil through the fill tube using a
funnel to bring it up to the top of the operat
-
ing range.
Note: Gasoline Engine: Use SAE 10W30 or
SAE 10W40 engine oil, rated for service SJ.
Shell Rimula 15W40 is also recommended and
provides service SL and CI-4 plus.
c. Hydraulic Oil: (Filled at the factory before
shipment.) The hydraulic oil tank is located
beneath the operator’s seat. Always wipe
off the area around the oil tank fill neck
before checking the oil level to prevent dirt
from contaminating the oil. Remove the cap
and make sure the oil level is a 1/4” below
the oil tank fill neck. If the oil level is low, fill
with Shell Rimula 15W40 or equivalent oil.
Equivalent oil should meet GM Allison C-4.
d. Tires: 8-10 psi Rear, 20-25 psi Front Caster
Tires
Note: New tires are overinflated in order to
properly seat the bead to the rim. The normal
working pressure for the traction tires is 8-10
psi. The front caster wheels should be inflated
to 20-25 psi.
2. Check that all Nuts, Bolts and Screws are
Tight.
3. Check the tension of the deck drive belts.
a. Remove the deck cover
b. The tension of the deck drive belts are
maintained by a spring mechanism that
adjusts for wear and stretch.
c. Examine the belts for cuts, fraying, and
excessive wear. Replace if any of these are
detected.
d. Replace the deck cover.
4.
Adjust the Mowing Deck:
The cutting height
is set anywhere in the range of 1-1/2" to 5".
You may need to adjust the mowing deck to
achieve the proper angle for mowing. Follow
the procedures below to set the appropriate
angle to the mowing deck.
a. Park the mower on a flat paved surface,
engage the parking brake, shut off the
engine, remove the key from the ignition
switch, remove connection of the spark
plugs and using the second foot pedal,
lower the mowing deck into the cutting posi
-
tion.
b. Using a ruler, pencil and paper, measure
and note the distance from the paved sur
-
face to the bottom edge of the mowing
blade at the front and the back of the deck
on each side of the mower. (Four dimen
-
sions.)
Note: The front edge of the mowing deck
should be 1/8"-1/4" below the rear edge of the
deck so that the blades are cutting grass in
only the front half of their circular path. This
decreases friction and reduces the drive power
required.
c. If the dimension at the front of the mowing
deck is 1/8"-1/4" lower than the dimension
at the rear of the deck on each side of the
mower, do not adjust. If not, you will need to
adjust the Deck Lift Spring Assist (See Fig
