General Maintenance and Repair
Safety Notes
DANGER
Read the safety notices in the truck Mainte-
nance and Operator's Manuals.
● 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.
● 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.

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.
11. Only use original Crown spare parts to ensure the
reliability, safety and suitability of the Crown truck.
Before Leaving the Truck
● Stop the truck.
● Lower the fork carriage fully.
● Apply the parking brake.
● Turn off the travel switch and remove the key.
● Block all wheels when parking on an uneven
surface.
Before Carrying out Work on the Truck
● Raise the truck to free the drive wheel. Press the
emergency Stop button and disconnect the
battery.
● Prevent the truck from rolling away.
● 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.
● 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
● Check the safety devices.
● Get into the driver's seat.
● Check the operation of the lifting device, travel
direction switch, speed control, steering, warning
devices and brakes.
Warnings and Labels on the Truck
During regular maintenance check that the warnings
and labels on the truck are complete and legible.

Using the Manual
The manual is divided into sections. The following table
shows how the manual is structured.
A01M-gb
General
The present manual is designed for Customer Service
engineers who wish to familiarise themselves with the
maintenance work required for the various truck compo-
nents.
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.The-
se are listed in a separate manual.
Spare parts can be ordered by quoting:
● The truck specification number
● The truck model number
● 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

Jacking up the Truck
CAUTION
Always support a raised truck with wooden
blocks or other suitable equipment, thereby
relieving the jack.
The instruction "jack up the truck" always assumes that
the raised truck will be lowered onto a secure surface.
To jack up the truck, proceed as follows (Picture MS-
6620-003):
● Lift the forks to maximum height.
● Secure both loadwheels with a wedge (1).
● Apply a jack with sufficient capacity (> 900 kg) at
the middle of the chassis frame and raise the
truck (2).
● Place sufficiently sized woodenblocks (hard
wood)
on both sides underneath the chassis and lower
the truck onto the blocks (3).
● Apply the jack to the forks.
● Place a wooden block under the forks and lower
the truck onto it (4).
Fastening
screws
If there is sufficient distance between the truck centre of
gravity (e.g. 1B) and the rear end of the chassis frame
the truck can be supported by placing a block under the
rear end of the chassis frame (instead of the forks) -
point A in figure above. In this case, place an extra
wooden block under the tips of the lowered fork.
Lifting the Truck with a Crane
DANGER
Make sure the capacity of the crane and the
lifting device is sufficient. If a crane or truck
tips or a load falls, fatal injuries can result.
For lifting the truck, the forks must be in a raised posi-
tion (maximum height).
In order to attach the lifting straps to the truck at the
locations indicated, you must first tilt back the battery
compartment cover and remove the side panels.
Attach the straps (ropes, chains) to the hitch points as
shown in.
Required lifting capacity: 730 kg for a GPC with
1000 mm forks, 870 kg for a GPC with 2880 mm forks
(GPC without battery).

Required lifting capacity: 730 kg for a GPC with
1000 mm forks, 870 kg for a GPC with 2880 mm forks
(GPC without battery).
● Place the forks of the truck which is doing the
lifting under the GPC chassis as indicated by the
black forks under the GPC in the figure below.
Exception: GPC with fork length over
2000 mm and without battery. Position the forks
of the truck which is doing the lifting as indicated
by the grey forks under the GPC in the figure
below. The forks of the GPC must be in their
uppermost position. Insert a 120 mm thick block
between the forks of the GPC and the corre-
sponding fork of the lifting truck.
● Firmly secure the GPC to the forks of the truck
which is doing the lifting (e.g with appropriate
straps).

the floor during the procedure.
● Position the fork under the chassis as shown.
● Lift the truck (at the front part) approximately 20

ance with the Maintenance Manual.
● When storing in adverse environmental conditions
(e.g. saline atmosphere), take appropriate meas-
ures to cover the truck to prevent corrosion.
