Hi Pot Test Instructions
This test must only be performed by a qualified electrician.
Your Trackmaster ® Treadmill has been Hi-Pot tested at the factory just prior to shipment and
found to be within specifications. However, some facilities require Hi Pot test verification
before the treadmill is put into service. The following instructions must be followed to
prevent permanent damage to the Trackmaster
® electronic control system. Failure to follow
these instructions will void your warranty.
NEVER USE AN AC HI-POT TESTER ON THIS TREADMILL !
Using an AC HI-Pot tester will permanently damage the DC
motor controller board rendering the treadmill inoperable.
