SAFETY

SAFETY PRECAUTIONS

Your Carrier Transicold unit has been designed with the safety of the operator in mind. During normal operation, all moving parts are fully enclosed to help prevent injury. During all pretrip inspections, daily inspections, and problem troubleshooting, you may be exposed to moving parts. Please stay clear of all moving parts when the unit is in operation and when the unit main power switch is in the START/RUN position.

Engine Coolant

The engine is equipped with a pressurized cooling system. Under normal operating conditions, the coolant in the engine and radiator is under high pressure and is very hot. Contact with hot coolant can cause severe burns. Do not remove the cap from a hot radiator. If the cap must be removed, do so very slowly in order to release the pressure without spray.

Battery

This unit is equipped with a leadacid type battery. The battery normally vents small amounts of flammable hydrogen gas. Do not smoke when checking the battery. A battery explosion can cause serious physical harm and/or blindness.

SPECIFIC WARNING AND CAUTION STATEMENTS

To help identify the label hazards on the unit and explain the level of awareness each one carries, an explanation is given with the appropriate consequences:

DANGER

DANGER -- warns against an immediate hazard which WILL result in severe personal injury or death.

WARNING

i 62-11161

SPECIFIC WARNING AND CAUTION STATEMENTS (Continued)

WARNING

When removing the radiator cap, wait at least ten minutes after the engine has stopped and cooled down. Otherwise, hot water may discharge from the radiator, scalding anyone nearby.

WARNING

Check the injection nozzle only after confirming that nobody is near the spray. If the spray from the nozzle contacts the human body, cells may be destroyed and blood poisoning may result.

CAUTION

Stop the engine when attempting to check and change the fuel line.

1.2.1 E2B ENGINE

Carrier/Kubota supply diesel engines conforming to federal emission regulations. The emission controls that have been put into effect have been stepped up to the second stage. Carrier/Kubota has executed the improvement in the engines to conform to this regulation.

In order to discriminate between engines conforming to

Tier 1 / Phase 1 requirements and those conforming to

Tier 2 / Phase 2 requirements, we have adapted E2B as a new model name for the engines conforming to Tier2 /

Phase 2 regulations.

In the after--sale services for Tier 2 / Phase 2 engines, only use the dedicated parts for E2B models and carry out the maintenance services accordingly.

1.2.2 CYLINDER NUMBER

1.3 GENERAL PRECAUTIONS

During disassembly, carefully arrange removed parts in a clean area to prevent confusion latter. Screws, bolts and nuts should be replaced in their original position to prevent reassembly errors.

When special tools are required, use Carrier Transicold genuine special tools. Special tools which are not frequently used should be made according to the drawings provided.

Before disassembling or servicing electrical wires, make sure to always disconnect the grounding cable from the battery first.

Remove oil and dirt from parts before taking any measurements.

Use only Carrier Transicold genuine parts for parts replacements to maintain engine performance and to ensure safety.

Gaskets and o--rings must be replaced during reassembly. Apply grease to new o--rings or oil seals before assembling.

The cylinder numbers of diesel engines are designated as shown above. The sequence of cylinder numbers is given as No.1, No. 2, and No. 3 starting from the gear case end of the engine.

3 3

1. Grease

2. Force

3. Place the Sharp Edge against the Direction of Force

A External Snap Ring

B Internal Snap Ring

When reassembling external or internal snap rings, position them so that the sharp edge faces against the direction from which force is applied.

A newly serviced or reassembled engine should be run--in with no load for 15 minutes. Serious damage to the engine may result otherwise.

1--3 62--11161

1.4 TORQUE SPECIFICATION

Screws, bolts and nuts must be tightened to the specified torque using a torque wrench. Several screws, bolts and nuts such as those used on the cylinder head must be tightened in the proper sequence and at the proper torque.

1.4.1 Torque Specifications For Special Use Screws, Bolts and Nuts

In removing and applying the screws, bolts and nuts marked with “*”, a pneumatic wrench or similar tool, if employed, must be used with care. Failure to do so may result in stripped or seized screws, bolts and nuts.

When replacing “*” marked screws, bolt and nuts, apply engine oil to their threads and seats before reassembly.

The letter “M” in size and pitch means that the screw, bolt or nut dimension is metric. The size is the nominal outside diameter in mm of the threads. The pitch is the nominal distance in mm between two threads.
