CAUTIONS
USE ONLY CLEAN, DRY, OIL FREE, FILTERED AIR
►DO NOT connect the tester or release vehicle brakes without FIRST CHOCKING THE TIRES and
securely supporting the vehicle. The trailer can move(walk) during testing.
►DO NOT weld on the vehicle while the vehicle is connected to the tester. The tester is grounded
to the vehicle chassis and welding may damage the tester’s circuitry.
►DO NOT operate other systems or electrical devices on the vehicle during brake system testing.
Doing so may cause inaccurate results.
►Engines operating near the tester may interfere with remote control operation. If difficulty is
experienced, install electrical noise suppression on the offending engine.
►Each tester is matched to one remote control via Bluetooth. If you experience interaction of
remotes of multiple testers operated in close proximity, contact LITE-CHECK for assistance.
►For reliable remote control operation, the tester antenna must be fully exposed.
►EMERGENCY air must be supplied to the trailer’s brakes before the 1200’s SERVICE brake
function will operate. This prevents ‘Compounding’ and possible structural damage to brake
components.
►Use only air hoses and fittings as supplied by Lite-Check. Others may produce erroneous results
during brake timing tests.
►In order to safely perform consistent and accurate tests, operators of the LITE-CHECK 1200 must
first familiarize themselves with this manual, the tester, and the brake system being tested.
Should you have any questions, contact LITE-CHECK Technical Support at 800-343-8579, 7:00
