Sprintex recommends performing the following vehicle checks prior to installing the supercharger.

1. Check that the factory fuel system is operating correctly.
2. Inspect the factory exhaust catalyst for blocks or damage
3. Ensure that the vehicles ignition system is working correctly.
4. Install new standard spark plugs and set gap.
5. Replace the fuel filter if the vehicle has travelled more than 15,000 Km or 9000 miles.
6. It is recommended to run at least one full tank of premium unleaded fuel through the vehicle prior to installing the supercharger system to prevent any possible damage that may occur due to running the supercharged engine on lower octane fuel. (Refer details on the next page)

DISASSEMBLY INSTRUCTIONS

SAFETY WARNING

No unauthorised service or alteration may be undertaken to the Sprintex supercharger. Installation should be carried out in a workshop which is a safe and ventilated working environment with equipment and procedures compliant with local authority guidelines and legal requirements. Installers should ensure adequate hearing, eye, and physical protection is used at all times during the installation process. Installers should take reasonable precautions to avoid fatigue and closely follow the installation instructions during every installation. Sprintex recommends installation should not be carried out unsupervised. Sprintex, its directors, employees and agents will not accept liability for damage accident or injury resulting from the installation process. Safety warnings are also provided throughout this document.


Preparation

NOTES:

It is critical during the programming process that the tuner doesn’t get interrupted. This could cause the vehicle computer to “crash”, and the vehicle to be inoperable.

Interruptions can be caused by a drop in battery voltage, causing the vehicle’s computer to cycle on and off, by accessories that communicate with the vehicle’s computer or by the programming cable being unplugged or not securely connected.

We recommend removing fuses for any aftermarket accessories that draw voltage from the battery.
