SAFETY INFORMATION
To avoid personal injury or property damage during system operation, read and follow all
CAUTIONS, WARNINGS, and INSTRUCTIONS included with or attached to each product .
ENERPAC CANNOT BE HELD RESPONSIBLE FOR DAMAGE OR INJURY RESULTING FROM
UNSAFE USE OF PRODUCT, LACK OF MAINTENANCE, OR INCORRECT PRODUCT AND SYSTEM
APPLICATION . Contact Enerpac when in doubt as to applications and safety precautions .
WARNING
JH jacks are NOT equipped with a stop ring to
retain the plunger. To prevent plunger
over-extension, a port is provided to vent the
oil out of the cylinder as the plunger reaches the
maximum stroke. When the RED LINE around the
plunger becomes visible, the plunger is at
maximum extension. Further extension could result
in the plunger being forced out of the cylinder.
WARNING
To avoid personal injury, always wear proper personal protective gear when operating
hydraulic equipment, i.e. safety glasses, gloves, etc.
WARNING
Make sure that jacks are protected from external sources of damage, such as
explosive heat, flame, moving machine parts, sharp objects, and corrosive chemicals.
DO NOT expose equipment to temperatures above 150°F (65°C).
CAUTION
Use only Enerpac hydraulic fluid. DO NOT use brake or synthetic fire resistant fluids
because they will damage the jack seals.
WARNING
Provide a solid and level foundation
adequate to support the load being lifted.
WARNING
Position the jack to distribute the load over the
entire base of the jack. The jack plunger must be
centered in the line of force of the load as it is being
lifted.
WARNING
Stay clear of loads supported by hydraulics.
Jacks are lifting devices ONLY. After the load has
been raised, it should be blocked, using material
capable of supporting the load.
WARNING
DO NOT exceed rated stroke. If you need to lift a
load further, support the load, raise the level of the
jack with a sturdy support and then continue the
lift.
WARNING
DO NOT lift a load which exceeds the capacity of
the jack. The load rating is marked on the jack
nameplate.
WARNING
If the jack is subjected to abnormal or shock loads, it should be inspected immediately
by a qualified hydraulic technician.
