Jacks
Proper maintenance of jacks is essential for safety. All jacks must regularly be lubricated.
The jack must be properly inspected and maintained before use.
Each jack must be inspected according to the following schedule:
- When jacks are used continuously or intermittently at one site, they should be inspected at least once every six months.
- When jacks are sent out of the shop for special work, they should be inspected when sent out and inspected when returned.
- When jacks are subjected to abnormal loads or shocks, they should be inspected before use and immediately thereafter.
To set up a jack, make sure:
- the base of the jack must rest on a firm, level surface
- the jack must be correctly centered
- the jack head must bear against a level surface
- the lift force must be applied evenly
