SECTION 2

SAFETY

Please take the time to carefully read this users manual. It
will assist you in fully utilizing the features of the
ACCUTEK III in a safe and effective manner.

The ACCUTEK III has the potential to deliver high voltage

and can produce much higher voltages when connected to other devices
(eg. ignition coils).

This device utilizes storage capacitors and can hold a charge for an
extended period of time - even if the power switch is in the OFF posi-
tion.

This manual has been published for negative ground systems. Leads
must be reversed when testing positive ground systems.

Purge all fuel from the engine before performing any static engine tests.

As with any electrical device, caution must be observed when using this
product.

Multi-strike ignition systems must be operated in single strike mode
when testing with the ACCUTEK III.

DO NOT USE IN AN EXPLOSIVE ATMOSPHERE

No tests should be performed with the ACCUTEK III unless the opera-
tor is fully capable of protecting himself from electrical shock.

Do not exceed the input or output specifications of the ACCUTEK III.

Should any assistance be required in the safe operation of the
ACCUTEK III, please contact:
