Information:

Safety is basically common sense. There are standard safety rules but each situation has its own peculiarities which cannot always be covered by rules. Your experience and common sense will be your best guide to safety. Be ever watchful for safety hazards and correct deficiencies promptly.Use the following safety precautions as a general guide to safe driving and maintenance practice. It is your responsibility to practice and promote safety. 1. Obey the rules of the road.2. Never adjust or repair engine or vehicle while it is in operation.3. Remove all tools and electrical cords before starting engine or operating vehicle.4. Keep work area clean.5. Store oily rags in containers.6. Store flammable liquids in a safe place away from the work area.7. Do not smoke around batteries. Hydrogen gas generated by charging is explosive. Keep batteries in a well ventilated area.8. Observe NO SMOKING signs.9. Do not wear loose clothing.10. Never operate an engine except in a well ventilated area.11. When cleaning with air do not exceed 30 PSI (2, 1 kg/cm2). Servicing cab-over truck engines require additional safety precautions as follows: Before Tilting Cab:1. Check clearance above and in front of truck cab.2. Keep tool chests and workbenches away from front of cab.3. Inspect sleeper and cab interior for loose luggage, tools and liquid containers which could fall forward.4. Check "Buddy" or "Jump" seats on right side of cab to be sure they are secured in place. While Tilting Cab1. Be sure the governor, transmission and clutch linkage do not interfere with the cab.2. Check position of steering shaft U-joint to prevent binding.
BEFORE TILTING CAB CHECK AREA FOR SUFFICIENT CLEARANCE AND OBSTRUCTIONS3. Never work under a partially tilted cab, unless it is properly secured.4. When cab is tilted past the over-center position, use cables or chains to prevent it from falling. Do not rely on cab hydraulic lift mechanism to retain or break the fall of the cab in any position beyond the over-center point. While Cab is Tilted1. If it's necessary to open a door, take care to avoid damage to door hinges and/or window glass. While Lowering Cab1. Watch all governor, steering, clutch and transmission linkage. Bellcranks may turn over center, shift levers jam against bottom of cab and some models of clutch links separate when tilting cab. These clutch linkage components can miss their mating part when the cab is lowered.2. Be sure mating ends of exhaust and air cleaner inlet pipes align properly.3. Be sure cab lowers properly on mounting and locating pins. Twisted or misaligned cabs may miss locating pins and cab latch will not secure cab in locked position.4. Lock cab latching mechanism when cab is all the way down.
