  3. Parking • ONLY PARK OUT FRONT • Any vehicle parked in back lot will be ticketed/towed • All vehicles to be worked on MUST have a properly filled out “BLUE” form on dash

  4. Other things • SMOKING: State law = 25 ft from doors • Butts in containers! • FIRST AID KITS: Note location • KEEP your area clean – leave the classroom/shop clean!

  5. Hydraulic Floor Jacks • Be careful to lift at manufacturer’s recommended locations only. • The jack must be able to roll as the vehicle rises, or the jack pad may slip! • Always use jack stands to support the vehicle after lifting.

  6. Lift Safety (cont’d) • Always follow the lift guide and vehicle manufacturer’s service information when lifting a vehicle. • Ensure proper contact between the lift and the vehicle. • Lift the vehicle about six inches, shake, and recheck contact points.

  7. Hydraulic Jack andSafety Stand Safety • Never attempt to lift something heavier than the jack is designed for. • Be sure the jack lift pad is under the specified vehicle lift point. • Position the safety stands under a strong chassis member. • The safety stand legs must contact the floor evenly. • Remove the jack after the vehicle is sitting on the safety stands.

  8. Lift Safety • Be sure the lift is completely lowered. • Do not run into or over the lift arms. • Be sure the lift pads contact the specified vehicle lift points. • Close the doors and trunk lid. • After the vehicle is raised, be sure the safety mechanism is engaged.

  9. Vehicle Lifts Electric or hydraulic • Frame contact

  10. Vehicle Lifts • Wheel contact

  11. Lifting a Vehicle Safely • Follow vehicle manufacturer’s recommended lift points. • Use lift manufacturer’s precautions for use. • Have the instructor check the position of the rack pads.

  12. Lifting a Vehicle Safely(continued) • Shake the vehicle as soon as the wheels leave the floor. Make sure the vehicle is stable. • After the vehicle is raised, lower to engage a safety stop. • Be aware of the vehicle’s center of gravity (see Figure 2.23).

  13. Question • Technician A uses safety stands when removing large components from a hoisted vehicle. Technician B always lowers the vehicle on the mechanical locks after lifting the vehicle to proper working height. Who is correct? • Technician A only • Technician B only • Both Technicians A and B • Neither Technician A nor B • C = Both Technicians

Who is correct? • Technician A only • Technician B only • Both Technicians A and B • Neither Technician A nor B • B = Technician B only

  25. Hydraulic Presses Be extremely careful using a press: • Parts can explode under the 20–50 tons of pressure applied.

  26. Hydraulic Presses (continued) • Use safety guards. • Wear eye protection. • Watch for sudden pressure increases with no movement of the work.
