Introduction This publication is designed for the benefit of JCB Distributor Service Engineers who are receiving, or have received, training

by JCB Technical Training Department.

These personnel should have a sound knowledge of workshop practice, safety procedures, and general techniques associated with the maintenance and repair of hydraulic earthmoving equipment.

Renewal of oil seals, gaskets, etc., and any component showing obvious signs of wear or damage is expected as a matter of course. It is expected that components will be cleaned and lubricated where appropriate, and that any opened hose or pipe connections will be blanked to prevent excessive loss of hydraulic fluid and ingress of dirt. Finally, please remember above all else SAFETY MUST COME FIRST! The manual is compiled in sections, the first three are numbered and contain information as follows: 1 2 3

= = =

General Information - includes torque settings and service tools.

Care & Safety - includes warnings and cautions pertinent to aspects of workshop procedures etc.

Routine Maintenance - includes service schedules and recommended lubricants for the whole machine.

The remaining sections are alphabetically coded and deal with Dismantling, Overhaul etc. of specific components, for example: A B

= =

Attachments Body & Framework ...etc

The page numbering in each alphabetically coded section is not continuous. This allows for the insertion of new items in later issues of the manual.

Section contents, technical data, circuit descriptions, operation descriptions etc. are inserted at the beginning of each alphabetically coded section.

All sections are listed on the front cover; tabbed divider cards align directly with individual sections on the front cover for rapid reference.

Where a torque setting is given as a single figure it may be varied by plus or minus 3%. Torque figures indicated are for dry threads, hence for lubricated threads may be reduced by one third.

‘Left Hand’ and ‘Right Hand’ are as viewed from the rear of the machine facing forwards.

Note: In this manual the term ‘swing’ may sometimes be used in place of ‘slew’ and the term ‘arm’ may sometimes be used in place of ‘dipper’.

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

First Aid - Oil

Handling

Swallowing

New Oil

If oil is swallowed you should not induce vomiting. Get medical advice.

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

Used Oil Skin In the case of excessive skin contact you should wash with soap and water.

Used engine crankcase lubricants contain harmful contaminants. In laboratory tests it was shown that used engine oils can cause skin cancer.

Eyes

Here are precautions to protect your health when handling used engine oil:

In the case of eye contact, flush with water for 15 minutes. If irritation persists, get medical attention.

1. Avoid prolonged, excessive or repeated skin contact with used engine oils.

Fires

2. Apply a barrier cream to the skin before handling used engine oil.

Extinguish with carbon dioxide, dry chemical or foam. Firefighters should use self contained breathing apparatus.

! WARNING 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

3. Note the following when removing engine oil from skin: a. Wash your skin thoroughly with soap and water. b. Using a nail brush will help. c. Use special hand cleansers to help clean dirty hands. d. Never use petrol, diesel fuel or gas oil. e. Avoid skin contact with oil soaked clothing. f. Don't keep oily rags in pockets.

Hygiene

g. Wash dirty clothing before re-use.

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

h. Throw away oil-soaked shoes.

Waste Disposal

However, excessive or prolonged skin contact can remove the natural fats from your skin, causing dryness and irritation.

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

Low viscosity oils are more likely to do this, therefore particular care is necessary in handling used oils which can be diluted with fuel contamination.

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

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, and note the following:

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

Storage Always keep lubricants out of the reach of children.

Never store lubricants in open or unlabelled containers.

Service Intervals for Hydraulic Oil and Filters when using a Breaker or Crusher When using a breaker or crusher, contamination and degradation of the hydraulic oil occurs much more quickly than in normal excavating use. If the machine is used with increasingly degrading oil it can cause problems in the control valve, premature wear of the hydraulic pump and damage to the hydraulic system as a whole.

Servicing of the hydraulic oil and filters must be done more frequently according to the percentage of total operating hours involving use of the breaker or crusher. When a breaker or crusher is fitted, ensure that the oil and filters are changed at the intervals shown in the table below.

The hydraulic oil must be sampled and checked for contamination and degradation at the intervals shown.
