Build back up to 125 psi.

2. Shut engine off.
Check leak rate - brakes off. 3 psi per minute.
Apply brakes. Maximum leak rate is 4 psi after initial drop.
Fan off air pressure. Check required visual warning and optional audio
warning - 60 psi.
Tractor protection valve should pop at 20 to 40 psi. Spring brakes should

Interior

Check pedals and clutch adjustment, steering free-play. Start engine. Check oil pressure, temperature, ammeter, low air warning (60 psi), emergency valve pops at 40 psi, air build-up rate (85 to 100 in 45 seconds), horns, wipers, washers, defroster, heater, dome and panel lights. Adjust seat, seat belt, bedding, mirrors, windshield, emergency reflectors, mounted fire extinguisher, registration and permits, spare fuses, bulbs. Secure loose items.

Exterior

Inspect for body damage, doors, flaps, license plates, tires (pressure, cuts, valve caps, stem balance and slippage, tread depth). Hub oil, suspension, cracked or oiled drums and shoes, worn or loose linings, air hoses and light cord, drive line, fuel caps. Bleed air tanks. Fifth wheel. Spare tire rack and chain. Support legs and crank. Brake adjustment within 1 inch. Distribution of load. Security of load. Placards.
