Section 1 - General Information Identifying the Machine Serial Numbers

Identifying the Machine Serial Numbers Serial Number Plate

Unit Identification

Each machine has a serial number plate located at X. The 17 digit Vehicle Identification Number (VIN), and the serial numbers of the engine and transmission are stamped on the plate.

The serial number of each major unit is also stamped on the unit itself as shown below. If a major unit is replaced by a new one, the serial number on the plate will be wrong. Either stamp the new number of the unit on the identification plate, or simply stamp out the old number. This will prevent the wrong unit number being quoted when replacement parts are ordered.

Section 1 - General Information

Standard Torque Settings Zinc Plated Fasteners and Dacromet Fasteners Introduction Some external fasteners on Fastrac machines are assembled using an improved type of corrosion resistant finish. This type of finish is called Dacromet and replaces the original Zinc and Yellow plating used on earlier machines. The two types of fasteners can be readily identified by colour and part number suffix as follows: Fastener Type

Colour

Part Number

Zinc and Yellow

Golden finish

Z (e.g. 1315/3712Z)

Dacromet

Mottled silver finish

D (e.g. 1315/3712D)

As the Dacromet fasteners have a lower torque setting than the Zinc and Yellow fasteners, the torque figures used must be relevant to the type of fasteners. A Dacromet bolt should not be used in conjunction with a Zinc and Yellow plated nut, as this could change the torque characteristics of the torque settings further. For the same reason, a Dacromet nut should not be used in conjunction with a Zinc and Yellow plated bolt. Dacromet bolts, due to their high corrosion resistance are used in areas where rust could occur. Dacromet bolts are only used for external applications. They are not used in applications such as gearbox and engine joint seams or internal applications. Note: All bolts used on JCB machines are high tensile and must not be replaced by bolts of a lesser tensile specification.

Section 2 - Care and Safety Safety Check List Safety First

Safety First As well as the warnings in this chapter, specific warnings are given throughout the book. This section is designed to give a safety code for use of the machine generally and for operation and maintenance practices.

Safety - Yours and Others INT-1-3-1_3

All machinary can be hazardous. When a machine is correctly operated and properly maintained, it is a safe machine to work with. But when it is carelessly operated or poorly maintained it can become a danger to you (the operator) and others. In this manual and on the machine you will find warning messages. Read and understand them. They tell you of potential hazards and how to avoid them. If you do not fully understand the warning messages, ask your employer or JCB distributor to explain them. But safety is not just a matter of responding to the warnings. All the time you are working on or with the machine you must be thinking what hazards there might be and how to avoid them.

Section 3 - Maintenance Routine Maintenance Service Requirements

Obtaining Replacement Parts T3-004_2

We recommend you fit only JCB Genuine Parts. A Parts Book will help you identify parts and order them from your JCB distributor. Your dealer will need to know the exact model, build and serial number of your machine. See Identifying Your Machine in INTRODUCTION section. The data plate also shows the serial numbers of the engine, transmission and axle(s), where applicable. But remember if any of these units have been changed, the serial number on the data plate may be wrong. Check on the unit itself.

Lubricants

The collection and disposal of used oil should be in accordance with any local regulations. Never pour used engine oil into sewers, drains or on the ground.

Introduction It is most important that you read and understand this information and the publications referred to. Make sure all your colleagues who are concerned with lubricants read it too.

Handling New Oil

Hygiene

There are no special precautions needed for the handling or use of new oil, beside the normal care and hygiene practices.

JCB lubricants are not a health risk when used properly for their intended purposes.

Used Oil

However, excessive or prolonged skin contact can remove the natural fats from your skin, causing dryness and irritation. Low viscosity oils are more likely to do this, so take special care when handling used oils, which might be diluted with fuel contamination. Whenever you are handling oil products you should maintain good standards of care and personal and plant hygiene. For details of these precautions we advise you to read the relevant publications issued by your local health authority, plus the following.

Used engine crankcase lubricants contain harmful contaminants. Here are precautions to protect your health when handling used engine oil: 1

Avoid prolonged, excessive or repeated skin contact with used oil.

2

Apply a barrier cream to the skin before handling used oil. Note the following when removing engine oil from skin: a

Storage

Wash your skin thoroughly with soap and water.

b Using a nail brush will help.

Always keep lubricants out of the reach of children.

c

Never store lubricants in open or unlabelled containers.

Use special hand cleansers to help clean dirty hands.

d Never use petrol, diesel fuel, or paraffin for washing.

Waste Disposal

!MCAUTION

3

Avoid skin contact with oil soaked clothing.

It is illegal to pollute drains, sewers or the ground. Clean up all spilt fluids and/or lubricants.

4

Don't keep oily rags in pockets.

5

Wash dirty clothing before re-use.

6

Throw away oil-soaked shoes.

Used fluids and/or lubricants, filters and contaminated materials must be disposed of in accordance with local regulations. Use authorised waste disposal sites. INT-3-2-14

All waste products should be disposed of in accordance with all the relevant regulations.

Section 3 - Maintenance Routine Maintenance Health and Safety First Aid - Oil Eyes In the case of eye contact, flush with water for 15 minutes. If irritation persists, get medical attention. Swallowing If oil is swallowed do not induce vomiting. Get medical advice. Skin In the case of excessive skin contact, wash with soap and water.

Spillage Absorb on sand or a locally approved brand of absorbent granules. Scrape up and remove to a chemical disposal area.

Fires

!MWARNING Do not use water to put out an oil fire. This will only spread it because oil floats on water. Extinguish oil and lubricant fires with carbon dioxide, dry chemical or foam. Fire fighters should use self contained breathing apparatus. 7-3-1-3_1

Section 3 - Maintenance Routine Maintenance Service Schedules

Service Schedules A badly maintained machine is a danger to the operator and the people working around him. Make sure that the regular maintenance and lubrication jobs listed in the service schedules are done to keep the machine in a safe and efficient working condition.

!MWARNING Maintenance must be done only by suitably qualified and competent persons. Before doing any maintenance make sure the machine is safe. It should be correctly parked on firm level ground. To prevent anyone starting the engine, remove the starter key. Disconnect the battery and block the wheels when you are working beneath the machine. If you do not take these precautions you could be killed or injured. 9-3-1-1

Apart from the daily jobs, the schedules are based on machine running hours. Keep a regular check on the hourmeter readings to correctly gauge service intervals, see Instruments in Operation Section. Do not use a machine which is due for a service. Make sure any defects found during the regular maintenance checks are rectified immediately. If the machine is operating in ambient temperatures below -18째C [0째F] or above 38째C [100째F], change engine oil and filter, air and fuel filters at shorter intervals. Shorter maintenance intervals are also required if the machine is operated in a dusty environment or if frequent stops are made. Calendar equivalents: 10 Hours = Daily 50 Hours = Weekly 250 Hours = Three Months 500 Hours = Six Months 1000 Hours = Yearly 2000 Hours = 2 Years 4000 Hours = 4 Years

How to Use the Service Schedules T3-012_2

In the example shown, A shows all service requirements to be carried out every 10 hours and B shows the requirements to be carried out every 500 hours.

Fluids, Lubricants and Capacities Note: New engines DO NOT require a running-in period. The engine/machine should be used in a normal work cycle immediately, glazing of the piston cylinder bores, resulting in excessive oil consumption, could occur if the engine is gently run-in. Under no circumstances should the engine be allowed to idle for extended periods; (e.g. warming up without load). Whilst 15W/40 oil is

Coolant Mixtures T3-009_3

Check the strength of the coolant mixture at least once a year, preferably at the start of the cold period. Replace the coolant mixture according to the intervals shown in the machine's Service Schedule.

!MWARNING Antifreeze can be harmful. Obey the manufacturer's instructions when handling full strength or diluted antifreeze. 7-3-4-4_1

You must dilute full strength antifreeze with clean water before use. Use clean water of no more than a moderate hardness (pH value 8.5). If this cannot be obtained, use de-ionized water. For further information advice on water hardness, contact your local water authority. The correct concentration of antifreeze protects the engine against frost damage in winter and provides year round protection against corrosion. The protection provided by JCB High Performance Antifreeze and Inhibitor is shown below. 50% Concentration (Standard) Protects against damage down to -40 °C (-39 °F) 60% Concentration (Extreme Conditions Only) Protects against damage down to -56 °C (-68 °F) Important: Do not exceed a 60% concentration, as the freezing protection provided reduces beyond this point. If you use any other brand of antifreeze: – Ensure that the antifreeze complies with International Specification ASTM D6210. – Always read and understand the manufacturer's instructions. – Ensure that a corrosion inhibitor is included. Serious damage to the cooling system can occur if corrosion inhibitors are not used. – Ensure that the antifreeze is ethylene glycol based and does not use Organic Acid Technology (OAT).

Section 3 - Maintenance Routine Maintenance Greasing

Greasing General Information Read and understand Lubricants - Health and Safety, before greasing. You must grease the machine regularly to keep it working efficiently. Regular greasing will also lengthen the machine's working life. Refer to the Service Schedules for the recommended frequencies. Note: If working in muddy conditions the propshafts and PTO driveshafts must be greased daily. Note: The machine must always be greased after pressure-washing or steam cleaning. Extra care must be taken to ensure that propshaft universal joints and splines are greased regularly Greasing should be done with a grease gun. Normally, two strokes of the gun should be enough. Stop greasing when fresh grease appears at the joint. Use only JCB HP Grease. In the following illustrations the grease points are numbered. Count them off as you grease them. Refit the grease point dust caps after greasing.
