1. IMPORTANT safety regulations and warnings
WARNING
Read and understand the operating instructions before you start using the strut spring compressor. Misuse can result in DEATH
or SEVERE INJURIES .
These operating instructions are an integral part of the strut spring compressor. Keep them at a safe place for future reference,
and always pass them on to subsequent users of the strut spring compressor.
The purchaser of the strut spring compressor must ensure that the user has read and understood the operating instructions
completely before he uses the spring-compressing system.
The operating instructions must be available for the user at any time.
1.1 Target group
These operating instructions are intended for skilled personnel in motor vehicle workshops.
The strut spring compressor may only be used by trained specialists in motor vehicle workshops who are familiar with the
safe handling of special vehicle tools.
• Never allow unauthorized persons or minors to use the strut spring compressor.
1.2 Intended use

• Never use the strut spring compressor if it is damaged!
• Always ensure that no other persons are present in the working area while working with the strut spring compressor and,
if necessary, ask them to leave the area immediately!
• Always keep hair, clothing, and gloves away from moving parts!
• Interrupt your work immediately if you are unsure about using the strut spring compressor, and contact the customer
service department of GEDORE Automotive GmbH if necessary!
1.8 Emissions
Molybdenum disulde paste may leak when the strut spring compressor is used and may cause skin irritation when in
contact with the skin, and also pose a risk to the environment.
• After skin contact, clean the aected area immediately with a fat-dissolving soap.
• Immediately remove excessive molybdenum disulde paste with a cleaning cloth and dispose of in an environmentally
acceptable manner.
1.9 Maintenance
The spindles of the strut spring compressor can be damaged.
• Before each use, check the spindles of the strut spring compressor for damage and soiling, clean them if necessary, and
lubricate them only with molybdenum disulphide paste! (for example, GEDORE Automotive molybdenum disulde
paste - KL-0014-0030)
1.10 Troubleshooting
Always carry out maintenance work on the strut spring compressor in a de-energized state!
Problem: The spindle clamping nuts of the strut spring compressor are sluggish.
Reason: Spindles soiled or insuciently lubricated; wrong lubricant used.
Remedy: Clean the spindles of the strut spring compressor for damage and lubricate exclusively with molybdenum
disulphide paste. (for example, GEDORE Automotive molybdenum disulphide paste - KL-0014-0030)

3. Preparation
Before using the strut spring compressor for the rst time,
check that all parts included in the delivery are present, and
follow the instructions below.
3.1 Checking the scope of delivery.
3.2 Preparing the tool.
1. Depending on the vehicle, determine and prepare the
required components of the strut spring compressor as well
as the required accessories, according to the repair guide of
the vehicle manufacturer .
WARNING
The support plate [C] can slip o the strut; thus, the strut spring
compressor can drop or be catapulted around, and this can
result in DEATH or SEVERE INJURIES.
•Before use, always check the mounting of the support
plate [C]!
•Always mount the support plate
[C]with the mark “Top/
oben“ pointing upwards to the basic unit [A]!
2. Mount the support plate [C] according to Chapter 7. -
Check individual parts overview.
Then attach the support plate [C]as shown in Fig. 1, in the
correct position to the basic unit [A] using the socket head
cap screws [B] .
Fasten the socket head cap screws [B]clockwise with 10 Nm.
3.3 Preparing the vehicle.
ATTENTION
The vehicle can be damaged.
• Always observe the vehicle-specic application sequence in
the vehicle manufacturer's repair guide.
1. Lift the vehicle safely according to the manufacturer's
instructions and loosen or prepare all necessary parts.
For example:
Remove wheels. Secure the wheel suspension for example
using the support device VAS 6931/1 (accessory) and the
gearbox jack VAS 6931 or VAG 1383A (accessory) (Fig. 1).
Loosen the strut from the spring dome, and lower it slightly
above the gearbox jack.

4. Typical application
This application example describes the preload of a MacPherson
strut on the front axle. The basic vehicle-specic application
sequence is described in the repair guide of the vehicle
manufacturer.
4.1 Placing the strut spring compressor ...
Depending on the strut, the strut spring compressor
must be applied accordingly!
... e.g. On a MQB plattform / See Chapter 4.1.1
... e.g. On a MEB plattform / See Chapter 4.1.2
4.1.1 Placing the strut spring compressor
e.g. on a MQB platform
WARNING
The hooks
[A1]
as well as the support plate [C]can slip o
the strut and thus, the strut spring compressor can drop or
be catapulted around; this can result in DEATH or SEVERE
INJURIES.
• Be careful to remove dirt and loose rust from the suspension
strut support bearing.
• Make sure that the hooks [A1] engage fully and securely
at the top of the strut support bearing and that the pins of
the support plate [C] fully engage into the holes of the lower
spring plate!
1. Position the strut spring compressor on the strut as shown
in Fig. 3.
Make sure that the hooks [A1] securely engage at the top
of the strut support bearing (Fig. 3 A), and that the pins
of the support plate [C] fully engage into the holes of the
lower spring plate (Fig. 3 B).
2. Proceed to:
• Chapter 4.2 / Strut removal.
• Chapter 4.3 / Strut installation.

strut support bearing as shown in Fig. 4 A + B.
WARNING
The hooks [A1]as well as the support plate [C]can slip o the
support ring [D]or the strut and thus, the strut spring compressor
can drop or be catapulted around; this can result in DEATH or
SEVERE INJURIES.
• Make sure that the hooks [A1] engage fully and securely at
the top of support ring [D] , and that the pins of the support
plate [C] fully engage into the holes of the lower spring plate!
2. Position the strut spring compressor on the strut as shown
in Fig. 4.
Make sure that the hooks [A1] securely engage at the top
of the support ring [D] (Fig. 4 B), and that the pins of the
support plate [C] fully engage into the holes of the lower
spring plate (Fig. 4 C).
