SECTION 2: OPERATION
A. PREOPERATIONALCHECKS
CAUTION: BEFORE USINGTHE EQUIPMENT, THE OPERATOR
MUST CAREFULLYREAD THE INSTRUCTIONS IN THE SAFETY
SECTION OFTHIS MANUALAND IN THIS SECTION. THE
OPERATOR MUSTALSO BECOME FAMILIAR WITH THE TOW
TRACTOR’S CONTROLS, INDICATORS,AND EQUIPMENTAS
DESCRIBED IN TABLES 2-1 thru 2-7 OF THIS SECTION.
CAUTION: NEVER RUN THE ENGINEWITH RECEPTACLE
CONNECTED TO THE OPTIONAL ENGINE COOLANT HEATER.A
FLOW CHECK VALVE STOPS COOLANT FLOW THROUGH THE
HEATER WHILE THE ENGINE IS RUNNING. THE HEATER WILLBE
DAMAGED IF CONNECTED TO THE HEATER RECEPTACLE WHILE
THE ENGINE IS RUNNING.
NOTE: In temperatures below 40 °F(4.4 °C), ensure that in units with an
engine fuel heater option, heaters are operating 10 minutes prior to engine
starting and turned off before ENGINE STOP/RUN switch is placed in the
RUN position.
NOTE: In temperatures below 40 °F(4.4 °C), ensure that units with an
engine coolant heater option are connected to engine external power source 1
hour prior to engine starting and operation.
In order to ensure safe, reliable operation, perform the following checks prior to operating the tractor:
1. Ensure the park brake switch is applied (set to ON).
2. Walk around the tractor and inspect it for damage or missing equipment.
3. Check for damaged or under-inflated tires. Check that cold tire pressure is 130 psi
(896.3 kPa). Look for cuts and cracks in the tire’s sidewalls and for foreign objects in the
tread.
4. Check the front/rear axle differential cases and planetary hubs for oil leaks.
5. Check for proper operation of the hitches.

6. Check for damage to the vehicle’s lights and beacons. Check that all lights are in proper
working order.
7. Check that the fire extinguishers are in place and fully charged .
8. Look underneath the tractor for signs of leaking coolant, hydraulic fluid, transmission fluid,
or lubricating oil. If significant leaks are found, repair them before using the unit for regualar
operation.
9. Check the engine oil.
WARNING: DO NOT LOOSEN OR REMOVETHE RADIATOR CAP
WHEN THE COOLANT IS HOT. HOT COOLANT UNDER PRESSURE
CAN SPRAY OR BOILOUT, CAUSING SEVERE BURNS.
10. Check that the engine coolant level is approximately 1-1/2 in (4 cm) below top of radiator fill
neck. If not, add coolant as necessary, being careful not to overfill. Visually check for
coolant leaks.
11. Inspect the engine compartment for loose hardware, loose wires, and leaking lines or fittings.
12. Check the hydraulic fluid level in the sight glass on the hydraulic reservoir. The sight glass is
slightly above eye level on the driver’s side of the vehicle between the front and rear axles. A
very low fluid level indicates a serious leak in the system. If that is the case, find the leak and
repair it immediately.
13. Check the operation of the hazard flasher, stoplights, taillights, headlights, backup lights, and
dash panel lights.
14. Check the fuel level.
NOTE: By keeping the fuel tank as full as possible, the tendency for
moisture to condense on the inner surfaces of the fuel tank can be minimized
or eliminated. Top off the fuel tank at the end of the day’s operation as part
of the post-operation maintenance routine.
