Cautions
Block vehicle wheels from movement before releasing brakes
The antenna must be fully exposed for a clear radio signal
Do not arc weld while the tester is connected to the trailor. The tester is
grounded to the chassis and will be damaged.
Do not hook up electrical devices on the same trailer that the tester is
diagnosing. The tester needs a clean power supply.
Do not lengthen existing power cord on the tester. Attach the tester
power cord directly to a 12-volt battery or a regulated power supply.
Lengthening the power cord will cause a power drop.
Be aware of voltage spikes. The tester will only operate on regulated
power. Use a 12-volt battery or LITE-CHECK 311R Regulated Power
Supply.
Using a battery charger or power converter as a power source will
damage the tester. Do not charge a battery when the battery is
connected to the tester.
The tester will not operate efficiently
below 10.5 volts and will indicate “LOW
BATTERY” (LOW BAT)
The tester may shut down below 9.0
volts
If operating gasoline motors near the tester, be sure that they have
static suppression on the engine. Static can cause radio interference.
The emergency air must be applied before the service brakes will
operate. This prevents brake compounding.
