1.0 IMPORTANT RECEIVING INSTRUCTIONS
Visually inspect all components for shipping damage. Shipping
damage is not covered by warranty. If shipping damage is found,
notify carrier at once. The carrier is responsible for all repair and
replacement costs resulting from damage in shipment.
2.0 SAFETY ISSUES
Read all instructions, warnings and precautions
carefully. Follow any recommended safety
precautions to avoid personal injury or damage to
the jack. Simplex cannot be responsible for any damage or injury
from unsafe use, lack of maintenance or incorrect operation.
Do
not remove warning labels, tags, or decals.
In the event any
questions or concerns arise, contact SIMPLEX or a local Simplex
distributor for clarification.
The maximum working pressure of the jack hydraulic system
varies between 6,000 and 10,200 psi [414 and 703 bar],
depending on jack model. Refer to pressure listings in Table 1,
General Specifications.
If you have never been trained on high-pressure hydraulic safety,
consult your distributor or service center for information about a
Simplex hydraulic safety course.
A
CAUTION
is used to indicate correct operating or maintenance
procedures and practices to prevent damage to, or destruction of
equipment or other property.
A
WARNING
indicates a potential danger that requires correct
procedures or practices to avoid personal injury.
A
DANGER
is only used when your action or lack of action may
cause serious injury or even death.
Failure to comply with the following safety precautions could
result in equipment damage and/or personal injury:
WARNING:
Wear proper personal protective gear when
operating hydraulic equipment.
WARNING:
The jack is to be used for lifting only! Support
the load after completing the lift using approved
accessories or by other appropriate means. Never get
under a load being supported only by the jack.
WARNING:
Never exceed the rated capacity of the jack.
Allow for a margin of safety that accounts for possible
shifting loads or side loading conditions.
DANGER:
To avoid serious personal injury, keep
hands and feet away from hydraulic cylinder and
related components during jack operation.
DANGER:
Do not handle pressurized lines. Escaping
oil under pressure can penetrate the skin, causing
serious injury. If oil is injected under the skin, see a
doctor immediately.
WARNING:
The jack's internal relief valve must not be
repaired or adjusted except by an authorized service
center. Never tamper with overload protection devices.
Higher settings may result in equipment damage and/or personal
injury.
CAUTION:
When jack is not in use, fully retract the
cylinder and protect the entire unit from external damage.
Keep the jack clean, avoid weld splatter, and store in a
clean dry area. INSPECT ALL JACK COMPONENTS BEFORE USE.
CAUTION:
Keep the jack away from flames and
heat. For optimum performance, do not expose the
jack to temperatures above 150 °F [65 °C].
WARNING: BE SURE LIFTING ARRANGEMENT IS
STABLE BEFORE LIFTING LOAD.
Use jack only on a
solid and level surface, capable of supporting the load
and the base of the jack. Always center the load on the lifting
saddle of the jack. If the jack is not perpendicular to the load,
slipping or loss of load is possible.
WARNING:
Distribute the load evenly when performing
lifts with multiple jacks. Failure to heed this warning may
cause loss of load and/or failure of the jack, resulting in
property damage and/or personal injury.
IMPORTANT:
Hydraulic equipment must only be
serviced by a qualified hydraulic technician. For repair
service, contact the Authorized SIMPLEX Service Center
in your area. To protect your warranty, use only SIMPLEX oil.

WARNING:
Immediately replace worn or damaged parts
with genuine SIMPLEX parts. Standard grade parts will
break causing personal injury and property damage.
SIMPLEX parts are designed to fit properly and withstand high
loads.
CAUTION:
To avoid damage to jack internal
components, do not continue pressurizing the jack
cylinder after it reaches maximum extension or
retraction.
