2 – General introduction
2.1 How to use the manual
The service manual is divided into chapters containing the following
information:
• Functions and parameters – This chapter contains a basic descrip-
tion of the main functions of the truck and the control system para-
meters.
• Installation and initial operation – This chapter describes the work
that needs to be done before the truck is used for the first time.
• Maintenance – This chapter contains a general periodic mainte-
nance schedule and a detailed description of the maintenance to be
carried out.
• Troubleshooting – This chapter describes the error codes that ap-
pear in the display when the truck completely or partly stops work-
ing. The chapter also describes the reason why the errors occur and
suggested remedies.
• Step by step – This chapter describes the various parts of the truck,
for example the hydraulic system, including what the parts look like
and the service activities that need to be carried out. The various de-
scriptions are organised according to BT's C-code system.
• Appendixes – The appendixes contain:
- instructions for disposal
- information about electrical components and wiring diagrams
- hydraulics diagrams
- list of required tools
- information about general tightening torques
- oil and grease specifications
- Technical data.

2.2 Warning symbols
The following warning symbols are used in the service manual:
DANGER!
The word DANGER! means there is a risk of accident potentially lead-
ing to death or serious injury and material loss or damage. Always ac-
companied by the warning symbol.
WARNING!
The word WARNING! means that there are components sensitive for
electro-static discharges.
Follow applicable ESD-routines to protect the device.
IMPORTANT
The word IMPORTANT means there is a risk of material loss or dam-
age if the instructions are not followed. Also used to draw attention to
a non-standard torque.
2.3 Pictograms
Where suitable, pictograms are used to describe some actions. Mainly
this applies to the release and fastening of screws:
The pictogram gives information about type of screw head and turning
direction indicated with an arrow.
Additional text below the pictogram gives information about
‘s’: key size, ‘n’: number of screws and, where applicable, recommend-
ed torque.
One example of another pictogram type is “Cut tie wrap”:
The pictogram might have additional information below, saying how
many ties to cut.

3 – General safety rules
Only personnel trained in servicing and repairing this type of truck are
authorised to carry out service and repair activities.
3.1 Safety while working
To ensure that you work safely and to prevent accidents while working
on a truck, remember the following:
• keep the area where servicing activities are performed clean. Oil or
water will make the floor slippery.
• use the correct working position. Service activities often involve
kneeling or bending forward. Try sitting on a toolbox, for example, to
relieve the strain on your knees and back.
• loose articles and jewellery may become trapped in the moving parts
of the truck. So never wear loose articles or jewellery while working
on the truck.
• use the correct tools for the work you are carrying out.
• keep all tools well maintained.
• store and transport old oil according to applicable local regulations.
• do not flush solvents, etc. down the drain unless they are intended to
be disposed of in this way.
Follow the local disposal regulations.
• heated paint gives off harmful gases. So use sanding or a paint strip-
per to remove the paint at least 100 mm around an area where any
welding/grinding is to take place.

815, 816 6051502 2008-08-21 261828-040
3.2 Electrical system
When working on the electrical system of the truck, remember the fol-
lowing:
• a short circuit may occur if metal objects come into contact with live
connections. This can result in burns. So remove watches, rings and
other metal jewellery before starting work.
• always use insulated tools while working on the electrical system.
• always switch off the truck's power supply before opening the hoods
to the drive assembly and the electrical system.
• disconnect the battery when using electric welding equipment. The
welding current may damage the battery.
• always remove the battery plug when carrying out maintenance on
the truck, unless the instructions in this service manual state other-
wise.
• blow electric motors clean using compressed air.
• clean electrical panels, electronic cards, connectors, contactors, so-
lenoid valves, etc. with a moist cloth and a cleaning agent that will
not damage the part.
IMPORTANT
Risk of short-circuiting that may damage electrical components.
Do not break the warranty seal on the electronic cards.

Safe lifting

3.3 Safe lifting
All lifting must be carried out on a flat, nonslip and stable surface.
Asphalt floors must be avoided if possible.
• To prevent the truck moving while it is being lifted, it must not be lift-
ed with anyone on the platform or with the tiller arm in the lowered
position.
• If the drive wheel, which is braked, is being lifted the other wheel
must be chocked to stop the truck moving.
• Select the lifting point so that the lift is as light as possible, for exam-
ple one corner at a time. If the truck has marked lifting points on the
lower part of the chassis, these should be used for a well-balanced
lift.
• Ensure the area where you place the jack is clean and free of oil and
grease.
• Ensure there is no grease or oil on your hands or the jack lever.

815, 816 6051502 2008-08-21 261828-040
• Use the lever supplied with the jack. If the lever is too short, it will re-
quire more effort than is necessary. If the lever is too long there is a
risk that the jack will be overloaded.
DANGER!
Risk of crushing – a poorly chocked truck may fall.
• Never work under a truck that is not blocked with supports or secured
by a lifting device.
• Place supports:
- as close to the raised part of the chassis as possible to reduce the
falling height if the truck tips over
- so that the truck cannot roll.
•Never place a support under the jack to increase the lifting height.
•Never work under a lifted truck without appropriate supports.

Tilt stops
To increase truck capacity, tilt stops are fitted to some trucks. Tilt stops
are also available as an option.
It is, however, permissible to temporarily remove tilt stops when trans-
porting the truck, between different warehouses, for instance; but the
truck may not in this case be used to transport loads.
WARNING!
Reduced stability.
Trucks without tilt stops can tip over, if used to transport loads.
Ensure that tilt stops are refitted at the correct floor distance if they
have been temporarily removed.
The tilt stops are located on the rear corner of the support arm and con-
sist of stops (c), shims (b), bolts (d), and nuts (a) on the inside of the
chassis.
