operation - thusly the hands can be used for
other functions
8. Fuel Shutoff Valve: (See Figure 4.) Located
behind the operator’s seat, the valve has three
(3) positions: “off”, “Left Tank”, “Right Tank”.
Close this valve if you are not going to run the
mower for a period of 30 minutes or more to
prevent flooding the engine. The fuel system
operates under pressure when the engine is
running.
Note:
In the left tank position, fuel will be
drawn from the left tank only, and excess fuel
not consumed by the engine will be returned to
the left tank. This also applies to the right tank.
9. 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. The lever on the side
allows a choice of four seat back angles, plus a
folded-down position. Knobs in each armresr
allow them to be adjusted to the desired height.
10. Hourmeter (Digital Tachometer Optional):
(See Figure 1 on page 10) 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 displays running time.
11. Warning Lights: (See Figure 1) Indicator
lights are provided to notify when conditions of
“Low oil pressure”, “High temperature coolant”,
“Low alternator output”, and “Glo-plug activa-
tion” are present. A buzzer is activated with the
“High temperature coolant” light.
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 #2 Diesel fuel,
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. (see page 29 for more
specs.)
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 operating range.
(see page 29 for more specs.)
Note:
Shell Rimula 15W40 is recommended
and provides service SL and CI-4 plus.
c. Engine Coolant: Use Shell Dex-cool,
extended life anti-freeze diluted with water
to create a 50:50 mixture. Maintain the fluid
level in the expansion overflow tank at the
prescribed level indicated on the tank.
d. 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 1/4” below the oil
tank fill neck. If the oil level is low, fill with
Shell Rimula 15w40 or equivalent oil. Equiv-
alent oil should meet GM Allison C-4.
e. Tires: 10-12 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 10-12
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 proce-
dures 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,
