WARNING: To prevent personal injury and / or death, or damage to property, do not operate vehicle if there is loss of steering or suspension, which could cause loss of vehicle control.

WARNING: To prevent personal injury and / or death, or damage to property, if wheels or tires must be changed, obtain expert tire service help. Mounting and demounting of tires should only be performed by qualified personnel using necessary safety procedures and equipment.

NOTE: Retread tires are not recommended for use on steering axles of trucks.

Steering gear: Look for missing or loose fasteners, power steering fluid leaks, and damage to power steering hoses.

Frame: Check for cracks or bends in frame. Make sure there are no loose, cracked, bent, broken or missing crossmembers or crossmember fasteners.

Shock absorber: Check for cracks, leaks, and missing or broken mounting bolts or bushings.

Spring suspension: Check condition of spring for cracks, breaks, or shifting. Inspect spring hanger fasteners, shackles, U-bolts, and nuts for wear, damage, and tightness.

Brake chamber and hoses: Check to see that the brake chambers are not cracked or damaged, and are securely mounted. Check for broken, loose or missing parts. Check for cracked, worn or frayed hoses, and for secure couplings.

Brake lining and drum: With brakes released, check to see that brake linings (where visible) are not worn excessively thin (less than 1/4 inch [6 mm]) or contaminated by lubricant.

WARNING; To prevent personal injury and / or death, or damage to property, use only the following procedure to remove the pressure cap from the radiator or expansion tank. Allow the engine to cool first. Wrap a thick, heavy cloth around the cap. Unscrew the cap slowly to allow pressure to release from under the cap. After the pressure has been released, the pressure cap may be removed.

Cowl vent: Ensure air inlet cover is free of dirt and debris.

Coolant level: Do not remove pressure cap unless coolant is cool. Ensure fluid level is between the minimum and maximum fluid level range as marked on the plastic translucent reservoir.

Radiator and charge air cooler: Check for loose mounting and damage. Inspect condition of all hoses for damage, cracks, and leaks. Inspect for foreign material on face of cooling package. Carefully brush away collected materials without bending cooling fins to maintain proper airflow through cooling package.

Drive belts: Inspect all belts for frays, cracks, loose fibers, or visible signs of wear. With engine off, press on all belts to test for proper belt tensioner performance.

Windshield washer fluid level: Inspect the reservoir and see that the fluid level is enough to accomplish the upcoming mission. See Lubricant and Sealer Specifications chart, in the Maintenance Intervals and Specifications section, for the correct fluid type before filling. Do not use water in freezing climates.

NOTE: Check air lines and electrical wiring for proper security, damage, and chafing. Listen for audible air leaks.

NOTE: Check for signs of fluid puddles under vehicle or wet components in the engine compartment.

Trailer coupling cords: Inspect air lines and electrical cord for cuts, chafing, damage, and proper security. Check air lines for audible air leaks.

Work light(s): Check operation, and clean as needed.

Sliding fifth wheel (optional): Check for loose or missing pins in the slide mechanism. If air powered, check for air leaks. Make sure that fifth wheel is not so far forward that tractor frame or mud flaps will strike trailer landing gear during turns.

Lubrication: Make sure that top surface (face) of the fifth wheel has a coat of grease.

Mounting bolts and release handle: Look for loose or missing mounting brackets, clamps, bolts or nuts. All locking pins must be in place and free of damage. Ensure that release handle is in the engaged position and the safety latch is functioning and free of damage.

Deck plate and access steps: Check to ensure that the deck plate and steps are clean, securely bolted in place, and clear of loose objects.

WARNING: To prevent personal injury and / or death, or damage to property, if wheels or tires must be changed, obtain expert tire service help. Mounting and demounting of tires should only be performed by qualified personnel using necessary safety procedures and equipment.

Frame: Check for cracks or bends in frame. Make sure there are no loose, cracked, bent, broken, or missing crossmembers or crossmember fasteners.

Torque rods and shock absorbers: Check to see that torque rods are not cracked, broken, or missing. Check shock absorbers for cracks or leaks. There should be no missing or broken mounting bolts or worn bushings.

Brake lining and drum: With brakes released, check to see that brake linings (where visible) are not worn excessively thin (less than 1/4 inch [6 mm]) or contaminated by lubricant.

Wheel and lug nuts: Check for damaged or bent wheel. Check to see that all lug nuts are present and not loose (look for rust trails around nuts). Ensure that no cracks or damage are present at wheel mount holes.

Brake chamber and hoses: Check for cracked, worn or frayed hoses, and for secure couplings. Check to see that the brake chambers are not cracked or dented and that they are securely mounted. Check for broken, loose or missing parts.

Tires: Check tread depth and tire inflation, and note if tread is evenly worn. Minimum tread depth is 2/32 inch (2 mm) on all drive tires. Look for cuts or other damage to the tread sidewalls. See if valve caps and stems are missing, broken, or damaged. Check dual spacing to ensure that dual wheels are evenly separated, and that tires are not touching one another.

Hub: Check for obvious leaking on outside or inside of wheel. Inspect axle flanges and wheel seals for leaks and loose mounting hardware or broken items.

Spring suspension: Check condition of spring for cracks, breaks, or shifting. Inspect spring hanger fasteners, shackles, U-bolts, and nuts for wear, damage, and tightness.
