Safety First

All mechanical equipment can be hazardous if operated

without care or correct maintenance.

In this manual you will find warning messages. Read them.

Understand them. They tell you of hazards and how to

avoid them. If you do not understand the messages, ask

your employer or local JCB Distributor.

But safety is not just a matter of responding to the warn-

ings. All the time you are working with the attachment you

must be thinking what hazards there might be and how to

avoid them.

Do not work with the attachment until you are sure that you

can control it.

Do not start any job until you are sure that you and those

around you will be safe.

If you are unsure of anything, about the machine or the job,

ask someone who knows. Don’t assume anything - check

it out.

Using the Attachment and Site Safety

This section explains some techniques for efficient and

safe use of the machine and its attachment. Attention is

also drawn to the various safety aspects of operating on

site. Read and understand this section before you start

working with the machine. Practise using the attachments

until you are completely familiar with the controls and what

they do.

Before you start using the machine, tell your work mates

what you you will be doing and where you will be working.

On a busy site, use a signalman.

Remember that your machine is mobile. Whenever

possible, manoeuvre your machine into a position which

combines safety with efficiency.. If you have to choose,

remember that:

SAFETY MUST COME FIRST

!!

WARNING

Work sites can be hazardous. Inspect the site before

working on it. Look for potholes, weak ground, hidden

rocks etc. Check for utilities such as electric cables

WARNING

Underground Gas Pipes

Before you start using the machine, check your local

gas supplier if there are any buried gas pipes on the

site.

If there are buried gas pipes we recommend that you

ask the gas company for any specific advice regarding

the way you should work on the site.

Some modern gas pipes cannot be detected by metal

detectors, so it is essential that an accurate map of

buried gas pipes is obtained before any excavation

work commences.

Hand dig trial holes to obtain precise pipe locations.

Any cast iron pipes found should be assumed to be gas

pipes until contrary evidence is obtained.

Older gas pipes can be damaged by heavy vehicles

driving over the ground above them.

LEAKING GAS IS HIGHLY EXPLOSIVE

If a gas leak is suspected, contact the local gas

company immediately and warn all personnel on the

site. Ban smoking, ensure that all naked lights are

extinguished and switch off any engines that may be

running.

You are strongly advised to make sure that the safety

arrangements on site comply with the local laws and

regulations concerning work near buried gas pipes.

WARNING

Hillsides

Operating the machine on hillsides can be dangerous if

proper precautions are not taken. Ground conditions

can be changed by rain, snow, ice etc. Check the site

carefully.

Going uphill, reverse when unloaded and travel forward

when loaded. Going downhill, travel forwards when

unloaded and reverse when loaded.

Take special care when moving across a slope. If the

slope is too steep your machine could roll over. If you

must drive across a slope, keep the attachments close

to the ground.

Digging Chain Setup

It is recommended that the digging chain is set up as

shown in illustration A. That is in a ‘V’ configuration with the

single tooth 1 in the centre and leading point of the ‘V’. The

‘V’ is formed by using progressively wider spacers 2 and

teeth 1, so that as the chain 3 rotates the cut becomes

wider. Refer to Trench Widths and Depths for width and

depth limits.

Trench Widths and Depths

Refer to Specifications on page 22.

Note: Optional Trencher Chain Kits and Trencher Cleaners

are available (see Specification at the end of this section).

Digging with the Trencher

The following specific guidelines should be followed when

digging with a trencher.

1 Make an initial cut with the trencher boom 1 lying flat

along the ground.

2 As the chain is rotating begin inserting the nose of the

boom into the ground as A while slowly raising the

trencher a few inches off the ground as B. Both of

these operations should be done gradually (see the

Carrier Operator Manual - Loader Controls).

3 Gradually establish the trencher boom angle. Best

results will be obtained with an angle between 45

o

and

60

o

. The skid shoe 2 should be just above ground

level. Make certain the trench cleaner 3 is operating

freely if fitted.

4 The digging chain should rotate anticlockwise as at C

when viewed from the drive chain casing 4 side.

5 Whenever possible always dig along the centre line of

the trench. This makes it easier to control the

machinery and dig a straight trench.

6 Gently creep the carrier backwards as at D. Too fast a

speed will cause the trencher to stall.

7 Control the depth by adjusting the boom controls of

the carrier (see Operator Manual - Loader Controls).

8 Do not engage the ‘float’ control of the arm and

attachment if fitted as this increases the drag on the

system.

WARNING

Before moving the machine onto the trailer, make sure

that the trailer and ramp are free from oil, grease and

ice. Remove oil, grease and ice from the machine tyres.

Make sure the machine will not foul on the ramp angle.

See Static Dimensions in SPECIFICATIONS section for

the minimum ground clearance of your machine

2-2-7-5/1

On Site

Raise the carrier loader arm so that the attachment is

approximately 200 mm (8 in) above the ground. When

moving around the site follow as level a route as possible.

!!

WARNING

Never travel at excessive speed over rough terrain. The

resulting loss of control could cause the carrier to tip

over. This could lead to death or serious personal injury

as well as damage to the attachment and/or carrier.

B-1-2-11

On a Truck

!!

WARNING

Water, mud, ice, grease and oil on ramps or trailers can

cause serious accidents. Make sure ramps and trailers

are clean before driving onto them. Use extreme

caution when driving onto ramps and trailers. Always

reverse up a ramp if unloaded, travel forwards if loaded.

Always reverse down a ramp if loaded, travel forwards

if unloaded.

3-1-1-3

1 Drive the carrier up the ramps and onto the truck after

proceeding as described for On Site.

a If the attachment is being transported alone, lower

the assembly to the floor of the truck. Remove

from the machine (see Removing - JCB Robot

150, 160, 165, 170, 185, 190, 1105, 1110 and

1CX) and drive the carrier off the truck. Secure the

attachment to the truck using straps or chain of

sufficient strength.

b If the attachment is being transported with the

machine, lower the assembly to the floor of the

truck and switch off the engine. Block the wheels

and using the attachment points chain the carrier

to the bed of the truck as shown in the illustration.

Hydraulic Oils, Filtering and Cooling

Introduction

Generally speaking the hydraulic oil specified for the carri-

er can be used in the Trencher. However, since working

with the Trencher will heat the oil much more than excava-

tion work, the viscosity of the oil must be checked period-

ically when working in hot climates.

When the Trencher is used continuously, the temperature of

the hydraulic oil normalises at a certain level depending on

conditions and the carrier. At this temperature, the viscosi-

ty of the hydraulic oil should be 20 - 40 cSt (2.90 - 5.35

o

E).

The Trencher must not be started if the viscosity of the

hydraulic oil is above 1000 cSt (131

o

E) or operated when

the viscosity of the hydraulic oil is below 15 cSt (2.35

o

E).

Possible Result of using incorrect Oil

Oil too thick:

- Difficult start up.

- Stiff operation.

- Danger of cavitation in the pumps and motor.

- Sticky Valves.

- Filter bypass, impurities in oil not removed.

- Motor runs slowly.

Oil too thin:

- Efficiency losses (internal leaks).

- Damage to gaskets and seals, leaks.

- Accelerated wearing of parts, because of decreased

lubrication efficiency.

Note: We recommend different hydraulic oils for use in

summer and winter if there is an average temperature

difference of more than 35

o

C (95

o

F).

Special Oils

In some cases special oils (e.g. biological oils and non-

inflammable oils) can be used with the Trencher. Observe

the following aspects when considering the use of special

oils.

- The viscosity range in the special oil must be in the

given range (15 - 1000 cSt).

- The lubrication properties must be good enough.

- The corrosion resistance properties must be good

enough.

Note: Although a special oil could be suitable for the

carrier, it may not be suitable for the Trencher. Please check

with your JCB Distributor.

JCB OWNERS SHOULD ALWAYS CONSULT THEIR JCB

DISTRIBUTOR BEFORE CHANGING THE MACHINE

HYDRAULIC OIL.

Hydraulic Oil Purity

No separate filter is required for the Trencher. The carrier’s

oil filter will clean the oil flowing through the Trencher. The

purpose of the oil filter is to remove impurities from the

hydraulic oil since they cause accelerated component

wear, blockages and even seizure. Impurities also cause

the oil to heat and deteriorate. Air and water are also impu-

rities in oil. Not all impurities can be seen with the naked

eye.

Impurities enter the hydraulic system:

- During hydraulic oil changes and refilling.

- When components are repaired or serviced.

- When the Trencher is being installed on the carrier.

- Because of component wear.

Oil Filter

The carrier oil filter must fulfil the following specifications:

- The oil filter must allow maximum particle size of 25

microns (0.025 mm).

- The oil filter material must be man-made fibre cloth

or very fine gauge metallic mesh to withstand pres-

sure fluctuations.

- The oil filter must have a volume flow capacity of at

least twice the Trenchers maximum flow.

In general, oil companies guarantee new oils to have a

particle count of 40 microns maximum. When adding oil to

the system the oil must be filtered.

Lubricants

In the EEC all JCB lubricants are covered by individual

COSHH (Control of Substances Hazardous to Health)

leaflets which are available on request from your JCB

Distributor.

It is most important that all personnel concerned with

lubricants read and understand the information contained

in the relevant leaflets.

Some general guidance is given in the JCB Carrier Machine

Handbook.

Main Inspection

We recommend that the following inspection is done dur-

ing the first 50 - 100 hours of operation of a new Trencher

attachment. It is advisable to have this work done by your

JCB Distributor.

Check

1 Torque tightness of all mounting and securing

bolts/nuts.

2 All hydraulic connections.

3 For hydraulic hoses rubbing (check throughout full

operating pressure).

4 Trencher operating pressure/flow (see SPECIFICA-

TION).

5 Hydraulic oil temperature during continuous operation

(see SPECIFICATION).

6 Correct operation of Spoil Auger.

7 Correct operation of Trench Cleaner Assembly.

8 Check digging teeth for cracks and wear.

9 Change the carrier hydraulic filter(s).

Obtaining Replacement Parts

We recommend that you fit only genuine JCB replacement

parts. Your distributor will need to know the equipments

serial number, which is stamped on the Trencher data

plate(see GENERAL DESCRIPTION section).

Washing

Periodically, and before doing any maintenance work, we

recommend that the outside of the Trencher is steam

washed. Ensure that the pressure and return lines are

plugged before washing, to prevent ingress of moisture.
