1. Safety
1.1 Safety Precautions
Failure to observe and comply with the following
precautions could result in death or serious personal
injury. Property damage could also occur.
• Read and completely understand the safety
precautions and instructions in this manual before
operating the SHS or preparing it for use. Always
follow all safety precautions and instructions,
including those that are contained within the
procedures of this manual.
• Always wear protective head-wear, ear protectors,
footwear and gloves (at a minimum rigger type
gloves) suitable for safe operation of the tool.
The protective clothing must not interfere with
safe operation of the tool or restrict the ability to
communicate with co-workers.
• Be sure your workplace is safe. Follow the
instructions in your workplace’s standard
operating procedures and be sure to observe all
communicated safety precautions.
• Ensure all hydraulic components are rated to a safe
working pressure of 700 bar (10150 psi).
• Do not remove or disable the pump relief valve.
• The system operating pressure must not exceed
the pressure rating of the lowest rated component
in the system.
• Never set a relief valve to a higher pressure than
the maximum rated pressure of the SHS. If ratings
are different, relief valve setting should not exceed
the setting of the lowest rated component (pump
or cylinder).
• Do not overload equipment. Never attempt to move
a load with higher weight than the maximum load
value of the SHS. Overloading causes equipment
failure and possible personal injury.
• Always perform a visual inspection of the SHS
before placing it into operation. If any problems are
found, do not use the cylinder. Have the cylinder
repaired and tested before it is returned to service.
• Never use a cylinder that is leaking oil. Do not use
the SHS if is damaged, altered or in need of repair.
• Always lift the cylinder using a crane or other
suitable lifting device of sufficient rated capacity.
Use only the 4 hoisting eyes on the SHS frame to
attach the cylinder to the lifting device.
• Allow only trained and experienced personnel
to supervise and perform lifting and lowering
procedures.
• Be sure the operator has completed safety induction
training, specific to the work surroundings. The
operator should be thoroughly familiar with the
controls and the proper use of the tool.
• Be certain that no persons are working on or near
the SHS before moving of the load begins. Alert all
personnel in advance that the procedure is about
to occur.
WARNING
Read all instructions carefully. Follow all recommended
safety precautions to avoid personal injury as well
as damage to the product and / or damage to other
property. Enerpac 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 that any questions or
concerns arise, contact Enerpac or a local Enerpac
distributor for clarification.
Save these instructions for future use.
If you have never been trained on high-pressure
hydraulic safety, consult your distributor or service
center for information about Enerpac Hydraulic Safety
Courses.
This manual follows a system of safety alert symbols,
signals, words, and safety messages to warn the user of
specific hazards. Failure to comply with these warnings
could result in death or serious personal injury, as well
as damage to the equipment or other property.
The Safety Alert Symbol appears throughout
this manual. It is used to alert you to potential
physical injury hazards. Pay close attention
to Safety Alert Symbols and obey all safety
messages that follow this symbol to avoid the possibility
of death or serious injury.
Safety Alert Symbols are used in conjunction with certain
Signal Words that call attention to safety messages or
property damage messages and designate a degree or
level of hazard seriousness. The Signal Words used in
this manual are DANGER, WARNING, CAUTION, and
NOTICE.
Indicates a hazardous situation that, if not
avoided, will result in death or serious personal injury.
Indicates a hazardous situation that, if not
avoided, could result in death or serious personal injury.
Indicates a hazardous situation that, if not
avoided, could result in minor or moderate personal
injury.

important, but not hazard related (e.g. messages related
to property damage). Please note that the Safety Alert
Symbol will not be used with the signal word.
DANGER
WARNING
CAUTION
NOTICE

4L4627_b
• Lift only dead weight loads. Avoid lifting live weight
loads.
• Be especially careful when lifting loads such as
partially filled storage tanks, in which the center of
gravity could move or shift during lifting. Be aware
that the distribution of some loads can change
quickly and without warning.
• Keep all personnel clear of the work area while
lifting or lowering is in progress. To avoid personal
injury, keep hands and feet away from cylinder and
load during operation.
• Maintain communication with the operator at all
times during lifting or lowering to avoid accidents.
Use hand signals, two-way radios or other
appropriate forms of communication (as required
by applicable laws and regulations) if the load is
not visible to the operator.
• Operate SHS as required to ensure that the load is
moved evenly and at a controlled rate.
• Closely watch the load at all times during the moving
process. Stop immediately if the load becomes
unstable or appears to be moving unevenly.
• Always be certain that hydraulic pressure is fully
relieved and that the load is fully removed from
the SHS before disconnecting hydraulic hoses,
loosening hydraulic fittings, or performing any
cylinder disassembly or repair procedures.
• Any components that are blocked or stuck in
any way (and any parts connected to these
components) will be under mechanical tension.
If you release these parts, they could change
position suddenly and serious injury could result.
• Brake valves of pressurized functions (cylinders,
motors and accumulators) must never be removed
before depressurizing the respective function.
Failure to observe and comply with the following
precautions could result in minor or moderate
personal injury. Property damage could also occur.
• Be careful to avoid damaging hydraulic hoses.
Avoid sharp bends and kinks when routing hydraulic
hoses. Do not exceed the minimum bend radius
specified by the hose manufacturer. Using a bent
or kinked hose will cause severe back-pressure.
Sharp bends and kinks will internally damage the
hose, leading to premature hose failure.
• Ensure components are protected from external
sources of damage, such as moving machine parts,
sharp edges, weld spatter, corrosive chemicals
and excessive heat or flame.
• Do not drop heavy objects on hoses. A sharp
impact may cause internal damage to hose wire
strands. Applying pressure to a damaged hose
may cause it to rupture.
• Keep hydraulic equipment away from flames and
heat. Excessive heat will soften packings and
seals, resulting in fluid leaks. Heat also weakens
hose materials and packings.
• For optimum performance, do not expose hydraulic
equipment to temperatures of 150˚F [65˚C] or
higher.
CAUTION
• Immediately replace worn or damaged parts with
genuine Enerpac parts. Enerpac parts are designed
to fit properly and to withstand high loads. Non-
Enerpac parts may break or cause the product to
malfunction.
• To prevent damage to pump electric motor, check
specifications. Use of incorrect power source will
damage the motor.
• Any modifications to the SHS could cause a
dangerous situation and void the warranty.
• Keep the hydraulic and moving components of the
SHS clean to prevent the SHS from jamming or
causing damage to itself or other equipment.
• Switch the power off before inspection,
maintenance or repair of the SHS. Make sure that
relevant parts are no longer receiving power. If
possible, make a ground connection. Insulate any
adjacent components that are still receiving power.
• If work does need to be performed on components
receiving power, then a second person must be
present in the area to switch off the main power
switch in the event of an emergency. Cordon off
the work zone and only use certified and properly
insulated tools.
• Lubricate tools as directed in this manual prior to
operation. Use only approved lubricants of high
quality, following the lubricant manufacturers
instructions
Failure to observe and comply with the following
precautions could result in property damage and/or
void the product warranty.
• Always use Enerpac pumps and hoses.
• Always use Enerpac replacement parts.
• Check and inspect the electrical system of the
SHS at regular intervals. Problems, such as loose
connections and damaged or stuck wiring, must
be resolved immediately. Only use original fuses
and circuit breakers with the correct current value.
• Always follow the inspection and maintenance
instructions contained in this manual. Perform
maintenance and inspection activities at the
specified time intervals.

3. Transport
Lifting and hoisting work must be performed by trained
operators with certified lifting and hoisting equipment.
Before use, check the validity of these certificates and
qualifications.
For loading and unloading, only use lifting and hoisting
equipment capable for holding the loads in question.
The lifting and hoisting equipment must be stable
enough and have suitable lifting and hoisting capacity.
Loading and offloading should always be performed by
properly trained personnel.
Lift loads as described in the user manual (connection
points for lifting hooks) and observe the professional
standards.
Only use suitable containers with adequate load
bearing capacity for transport purposes. Secure the
load properly using suitable connection points and
twist locks (for the containers). When using twist locks,
secure them properly and check the locking mechanism
is working correctly.
Disconnect any power connections in advance, even if
the SHS only needs to be moved a short distance.
The equipment must be transported in a frame designed
for this purpose. This frame can be placed in a container
to provide good protection against weather influences
and give a good rigid protection. Make sure that all parts
are secured against sliding around. Refer to Figure 1 for

6. Installation
6.1 Handling
The frame can be lifted with a crane, holding it by the
lifting points previously explained. Refer to paragraph 1
for further information.
6.2 Hydraulic Oil Requirements
Use of Enerpac HF Series ISO 32 hydraulic oil is
recommended. Enerpac HF oil is available at your local
Enerpac Distributor or Authorized Service Center.
NOTICE
• Failure to use the correct oil type (high-quality ISO 32
hydraulic oil) may result in damage to cylinder hydraulic
components and will void the product warranty.
• Be sure that the oil is clean. The oil cleanliness should
be maintained to a maximum level of 18/16/13 per the
ISO4406 standard. If the oil develops a milky, cloudy
or dark appearance, it should be changed immediately.
• To avoid overfilling and possible equipment damage,
add oil to the pump reservoir only after all Synchoists are
completely retracted and system pressure is released.
• When using a hand-operated pump to power the
cylinder(s), it is permissible to use a high-quality brand
of ISO 15 hydraulic oil. The lower oil viscosity will result
in reduced pumping effort, especially in cold weather
conditions.
6.3 Hydraulic Connections
CAUTION
On double-acting cylinders be certain that hoses
are connected to BOTH couplers. Never attempt to
pressurize a double-acting cylinder if only one hose
is connected.
For installation of Synchoist cylinders, it is not necessary
to start-up the power pack.
It is advisable to connect the hoses with retracted and
horizontal positioned cylinders. If hoses are connected
with cylinders in the vertical position it may be impossible
to connect the hose in the small chamber due to the
pressure created by plunger weight.
Connect hydraulic hoses as follows:
• A Port is connected to the retract outlet of the HPU.
• B Port is connected to the advance outlet of the
HPU.
Figure 9: Distribution manifold ports
Perform the following steps to correctly connect the
hoses:
1. Keep cylinders connected to a hydraulic system
with a fluid cleanliness level minimum of NAS 1638
Class 6.
2. Remove dust covers/rubber plugs from oil ports
3. Inspect all threads and fittings in search of wear or
damage signs and replace as needed.
4. Clean all threads and fittings.
5. Make hydraulic connections for double-acting
cylinders using two hoses.
6. Fully hand-tighten all couplers. Loose coupler
connections will block the flow of oil between the
pump and the cylinder.
Check for leaks in system and have repaired by qualified
personnel.
