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, warn-
ings 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.

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 truck 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.

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
thisseries. Brochures can be obtained from your CROWN
dealer or from the following address:

Jacking up the Truck
To jack up the truck, proceed as follows:
The platform must be lowered (see illustration).
DANGER
Always support the raised truck on square
blocks or other appropriate material to
relieve the trolley. Never put your hands or
other parts of the body underneath a non-
supported truck.
● Improper handling of the truck or the
auxiliary equipment can result in fatal
accidents.
● Secure both loadwheels with a wedge (1).
● Apply a jack with sufficient capacity
(for LP without battery: > 1100 kg, with max.
battery: > 1400 kg) at the middle of the chassis
frame (2) and raise the truck (max. 20 mm).
● Place sufficiently sized wooden blocks (hard
wood) on both sides underneath the chassis and
lower the truck onto the blocks (3).
● Apply the jack to one of the outriggers.
Raise the outrigger until the loadwheel clears the
floor.
Maximum loadwheel distance off the floor 20 mm.
● Place a wooden block underneath the outrigger
and lower the outrigger onto the block (4).
● Jack up the outrigger on the other side and lower
it onto a block (5).

Lifting the Vehicle with a Crane
Attach the chains or lifting straps as shown in Figs.
M1908 and 1909.
DANGER!
Check that both the crane/lift truck and lifting
equipment have sufficient lifting capacity.
● A toppling crane or fork-lift truck or a falling
load can cause fatal injuries.
Lifting the Vehicle with a Fork-Lift
Truck
The LP 3010 / 3020 can be raised using a fork-lift truck.
Required capacity:
for the LP without battery, 1500 kg.
● The drive wheel must be pointing straight ahead;
the platform must be fully lowered.
● Position the fork of the lifting vehicle as shown in
the diagram.
● Secure the LP firmly to the forks of the lifting
vehicle (e.g. with transport straps).

Towing the vehicle away
If the vehicle is de-energised the drive-wheel brake is
active. The vehicle can be lifted and towed with a mini-
mum 1400 kg capacity fork-lift truck. The load wheels
remain on the floor.
● Position the forks under the chassis as shown in
the diagram.
● Raise the vehicle (at the front end) approximately
20 mm off the ground.
WARNING!
The drive wheel must no longer touch the
ground.
● Otherwise you will damage the vehicle.
● Tow the vehicle slowly forwards and only in a
