7. OPERATION

7.1. Pretrip inspection

The pre-trip inspection should be performed before picking up any load. This inspection is essential to

anticipate and help minimize the possibility of "over-the-road" problems. These checks take only a few

minutes.

1. Place the unit's main switch (4.) in the STOP (O) position.

2. Fuel - drain any water and impurities from the sump of the refrigeration unit fuel tank by opening

the drain-cock located on the bottom of the tank (if so equipped). Close the valve when only pure

fuel emerges. Check the fuel level in the tank, ensuring that the fuel supply is adequate for unit

operation. Refuel if necessary.

3. Engine Oil - the engine oil should be checked last since it is necessary for oil to drain out of the

block and into the oil pan to obtain a correct reading. Remove the plug/dip-stick, wipe it off and re-

insert it fully into the engine block. Once again, remove the dip-stick and observe the oil level; it

should be somewhere between the full and add marks. If it is below the add mark, add oil until the

level is correct.

4. Check coolant level through the

openings of the front grill:

complete coolant level if

necessary.

DO NOT remove the cap

from a hot radiator : burns

risks.

5. Battery - on unit equipped with serviceable batteries, the level of the electrolyte in each of the cells

should be checked. If the level is low, distilled water should be added to the correct level. Most

units, however, are equipped with low or no-maintenance batteries. Check battery connections

and battery supports.

6. Over-all Unit inspection - visually inspect the entire unit for leaks, loose bolts, frayed, loose, or

broken wires, etc. The radiator and condenser coils of the unit should be free of dirt, bugs,

cardboard, or any other debris that may obstruct airflow across the coils. The evaporator (located

inside the body) should be free of debris also, especially shrink-wrap, which is often used during

transport to prevent cargo shifting.

7. Truck body - The body should be inspected prior to loading. Check the door and vent seals for

damage and wear. Inspect the entire interior and exterior of the body to detect any damage

including in the inner and outer skins of the body. Damage to the insulation may compromise the

unit's ability to maintain the product temperature by increasing the amount of heat gain across the

truck body.
