1.1 Introduction
This manual describes the service procedures for ATLET picking trucks in the OP
series. Use the manual for quick and correct service of respective truck models.
You may find contradictions in the manual compared to the models supplied due to
optional designs and the like.
Warning!
If the truck is rebuilt after delivery or supplemented in such a manner that
safety may be affected, ATLET AB or its authorised representative should be
contacted.
The content of this service manual is protected by copyright law and may not be
copied, fully or in part, without written permission. The material has undergone
careful examination with regard to correctness. Subject to alteration.
In the event of inconsistent information in the Swedish and translated editions, it is
the Swedish edition that applies.

How to use the manual ATLET SERVICE MANUAL
1.3 How to use the manual
The manual is arranged according to the same principles as ATLET’s spare part
catalogues, i.e. a system consists of 12 sections, where sections 4 -12 contain
information limited to a specific part of the truck. For example, Chassis (section 4)
and Hydraulic System (section 8). Sections 1 - 3 in this manual contain more
comprehensive information regarding technical data, general service, instructions
and tools. The main principle for extra accessories is to place them under the
respective sections. Otherwise they are placed under section 12 “Miscellaneous”.
For this reason section 12 is not always included in the Service Manual.
For specific problems or information about procedures, look in the main index for
the correct section.

1.4.1 Lifting points
Figure above shows where the permitted lifting points are placed on the truck.
When lifting complete truck: Lift in the first instance in the upper mast strut, point
A. Make sure not to damage the hydraulic pipe between the cylinders.
Lifting with jack: Lift at point C.

SERVICE MANUAL Tips before next step
1.4.2 Safety instructions
When the truck is lifted using a jack, make sure you secure it with blocks. The truck
must not rest on the jack, while work is carried out.
Ensure that straps, wires or chains have a sufficient lifting capacity before lifting the
truck.
Pull out the battery plug before working on the electrical system.
Ensure that the drive wheel runs free of the floor before trouble shooting.
The system should not be pressurised, e.g. the pump motor shut off and the forks
down, when dismantling parts of the hydraulic system.
1.4.3 General safety risks when working on fork trucks
Extreme importance must be placed on precautionary measures to avoid accidents
during all work on the vehicle.
A general rule is to always implement preventive measures that are adapted to the
type of vehicle to be worked on. The general rules below must always be observed:
• Smoking or naked flames are strictly forbidden as there is a risk of explosion in
the vicinity of batteries and while working on gas equipped vehicles.
• The battery should always be protected during grinding work.
• The fire regulations for the building should also be observed.
The drive wheel should always be lifted up free from the floor during service work
to prevent the vehicle from moving. The vehicle must not rest solely on the jack, but
must be secured by some form of blocking.
To prevent injuries caused by crushing, the battery plug should always be pulled out
when working around the mast, reach carriage and hydraulic unit on electric Reach
Trucks. The mast, reach carriage and hydraulic unit can be actuated due to an
electrical fault or a mistake while working. The battery plug may only be connected
while trouble shooting, and when the greatest of care is exercised, (with the truck
raised).
Warning!
Standing on the reach carriage between the mast and battery partition with the
current connected to the truck can result in fatal injury!
When working on and around the mast and hydraulic unit, they must be locked by
using a mast lock, wooden blocks or some other appropriate means.
No other persons should be in the vicinity of the truck when it is test run in
conjunction with repair work, in view of the risk of accidents or near-accidents
caused by the truck making an unexpected manoeuvre.
When working on the gas equipment on gas driven vehicles the gas system should
be emptied first, if possible, by shutting the main tap and running the motor or
equipment until the system is empty and stops.

9. General information and technical data 1.7
Tips before next step ATLET SERVICE MANUAL
Escaping gas is heavier than air and has a tendency to collect in cavities, and can be
ignited by sparks or a naked flame. The machine should therefore be ventilated with
compressed air before service work is begun. Ventilation should also be carried out
after repairs before the motor or another unit is started, since sparks from the starter
or relays can cause explosions.
The system should not be pressurised, e.g. the pump motor shut off and the forks
down, when dismantling parts of the hydraulic system.
All metal objects such as watches and rings should be removed when working on
the electrical system, or in its immediate vicinity. A short-circuit from such objects
can result in serious burn injuries.
1.4.4 Environmentally hazardous waste – environment
Atlet AB takes care of the environment. Waste material in conjunction with repairs,
maintenance, cleaning, or scrapping, should be collected and disposed of in an
environment-friendly way and in accordance with the directives of respective
countries. Such work must only be carried out in areas intended for this purpose.
Environmentally hazardous waste, such as oil filters, batteries, hydraulic hoses and
electronics, can have a negative effect on the environment, or health, if handled
incorrectly. Recyclable material should be taken care of by specialised authorities.
1.4.5 Handling
Make sure that you have all the essential tools close at hand before starting work.
Before cabling or other electrical components are disconnected, check the colour
codes and check for damage to cables or connections.
When complex, complete components are repaired and dismantled, make sure that
you have good control of the different component parts to avoid the risk of confusion.
When repairing or maintaining sensitive components, make sure that you use clean
tools and work on a clean work surface.
Dismantle, inspect and adjust components according to the prescribed routines. See
respective sections for detailed information.
Make sure that gaskets and O-rings, etc. are replaced with new parts each time they
are dismantled.
Always use ATLET’s original spare parts.
Use the screws and bolts specified in the spare parts catalogue. Tighten according
to instructions. In those cases where the tightening torque is not specified, refer to
the table of standard tightening torque in section 1.7.

1.4.6 Trouble shooting
When you suspect a faulty component, do not replace it immediately. First check
the surrounding equipment and carry out complete trouble shooting routines. Make
sure you know the reason for the fault before replacing a component.

Note!
In cases where the machine plate has been lost or become illegible, it must be
renewed immediately. In order to identify the machine's serial number, there
is a plate located on each main component such as drive motor, gearbox,
hydraulic unit, TMC etc. For some machines there is even a plate attached
inside the battery compartment, or serial number punched on the side of the
mast.
