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

subjected to an abnormal load or shock, it should be thoroughly
examined to make sure it has not been damaged.
Hydraulic jacks exposed to freezing
temperatures must be filled
with an adequate antifreeze liquid.
General Safety Precautions
Employees who use hand and power tools and who are exposed to
the hazards of falling, flying, abrasive and splashing objects, or
exposed
to harmful dusts, fumes, mists, vapors, or gases must be
provided with the particular personal equipment necessary to
protect them from the hazard.
All hazards involved in the use of power tools can be prevented by
following five basic safety rule.
•
Keep all tools in good condition with regular maintenance- .Use
the right tool for the job.
•
Examine each tool for damage before use.
•
Operate according to the manufacturer's instructions. Provide
and use the proper protective equipment.
Employees and employers have a responsibility
to work together to
establish safe working procedures. If a hazardous situation is
encountered, it should be brought to the attention of the proper
individual immediately.
