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.
