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.

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

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.
