Safety Notes
DANGER
Read the safety notices in the truck Mainte-
nance and Operator's Manuals.
l Failure to do so could result in severe or
fatal injuries to maintenance personnel
and/or other persons.
Motorised vehicles can be dangerous if maintenance
and service are neglected. For this reason maintenance
and inspections must be carried out at regular short
intervals by trained personnel working to approved
company guidelines.
DANGER
Follow all national/local safety regulations
applicable for maintenance work, e.g. for
work on higher levels.
l Failure to do so could result in severe or
fatal injuries to maintenance personnel and/
or other persons.
Maintenance and Repair
1. Maintenance work must only be carried out in
accordance with the test and maintenance pro-
gram contained in the present Maintenance
Manual and any applicable service notices.
2. Only qualified and authorised personnel may
carry out work on the truck.
3. Always keep fire extinguishers in good working
condition. Do not approach fluid levels or leaks
with a naked flame.
4. To clean, use a non flammable, non combustible
cleaning solution which is groundwater-neutral.
Only carry out cleaning with an oil separator.
Protect the electrical system from dampness.
5. Keep the service area clean, dry and well-venti-
lated.
6. Do not allow oil to penetrate the ground or enter
the draining system. Used oil must be recycled.
Oil filters and desiccants must be treated as
special waste products. Relevant applicable
regulations must be followed.
7. Neutralise and thoroughly rinse any spilled battery
fluid immediately.

REV. 1 4/00
8. Keep the truck clean. This will facilitate the loca-
tion of loose or faulty components.
9. Make sure that capacity and data plates, warnings
and labels are legible at all times.
10. Alterations or modifications by the owner or
operator are not permitted without the express
written authorisation from Crown.

battery.
l Prevent the truck from rolling away.
l Before carrying out work on the hoist frame, the
lift mast or on the fork carriage: Block these parts
according to maintenance instructions in order to
prevent them from dropping.
l Only carry out operational testing when there is
sufficient room to manoeuvre, to avoid the risk of
injury to yourself and others.
Before Operating the Truck
l Check the safety devices.

General
The present manual is designed for Customer Service
engineers who wish to familiarise themselves with the
maintenance work required for the various truck
components.
It also contains troubleshooting sections which can be
used to identify and remedy truck faults.
INFORMATION
This book is not an operating manual. It is
designed solely for specialist personnel
who have been trained and authorised to
carry out the work described in the manual.
This manual therefore contains fewer and less detailed
warnings than the Operator's Manual, as the latter is aimed
at persons who have very little or no prior experience at
all.
Operating Instructions
This manual contains no operating instructions. An
operating instructions manual is supplied with the vehicle.
Additional copies can be ordered as required.
With the help of this manual you and your personnel will
be able to ensure the long service life, operational safety
and error free functioning of your CROWN vehicle.
Service Training
CROWN offers the appropriate vehicle related training for
service personnel. Details on this training can be obtained
from CROWN on request.
Ordering Spare Parts
The maintenance manual does not cover spare parts.
These are listed in a separate manual.
Spare parts can be ordered by quoting:
l The truck specification number
l The truck model number
l The truck serial number
This information can be found on the truck's data plate.
Only if this information is provided can the order be
processed quickly, correctly and reliably.
Please refer to the Technical Specifications Sheet for the
utilisable loads, technical data and dimensions for this
