Hydraulic Power Tools
The fluid used in hydraulic power tools must be an approved fire-
resistant fluid and must retain its operating characteristics at the 
most extreme temperatures to which it will be exposed.
The manufacturer's recommended safe operating pressure for 
hoses, valves, pipes, filters, and other fittings must not be 
exceeded.
Jacks
All jacks -lever and rachet jacks, screw jacks, and hydraulic jacks -
must have a device that stops them from jacking up too high. Also, 
the manufacturer's load limit must be permanently marked in a 
prominent place on the jack and should not be exceeded.
A jack should never be used to support a lifted load. Once the load 
has been lifted, it must immediately be blocked up.
Use wooden blocking under the base if necessary to make the jack 
level and secure. If the lift surface is metal, place a l-inch-thick 
hardwood block or equivalent between it and the metal jack head to 
reduce the danger of slippage.
To set up a jack, make certain of the following: the base rests on a 
firm level surface, .the jack is correctly centered, the jack head 
bears against a level surface, and the lift force is applied evenly.
Proper maintenance of jacks is essential for safety .All jacks must 
be inspected before each use and lubricated regularly. If a jack is
