Tools, Fasteners, and Safety

Figure 1-43. This vehicle fell from the hoist because the pads were not set correctly. No one was hurt, but the vehicle was a total loss.

(a)

SAFETY ARM CLIP

Figure 1-44. The safety arm clip should be engaged to prevent the possibility that the hoist support arms can move. (b)

Figure 1-42. (a) Tall safety stands can be used to provide additional support for a vehicle while on a hoist. (b) A block of wood should be used to avoid the possibility of doing damage to components supported by the stand.

5. Before lowering the hoist, the safety

latch(es) must be released and the direction of the controls reversed. The speed downward is often adjusted to be as slow as possible for additional safety.

ELECTRICAL CORD SAFETY Use correctly grounded three-prong sockets and extension cords to operate power tools. Some tools use only two-prong plugs. Make sure these are double insulated. When not in use, keep electrical cords off the floor to prevent tripping over them. Tape the cords down if they are placed in high foot traffic areas.
