Instruction Manual

This is a safety alert symbol. It is used to alert you to potential personal injury hazards.
Obey all safety messages that follow this symbol to avoid injury or death

DANGER:

 To avoid personal injury keep hands and feet away from work area during operation

1.0 Product Information

DURAPAC – Hydraulic Bench Presses are engineered to meet Industrial Standards for Performance
and Safety. The HP-10 unit incorporates a two speed hydraulic hand pump with force gauge, hose
and a 10 ton 152 mm stroke spring return cylinder. The HP-10 bench press is ideal for workshop
pressing jobs such as the installation or removal of bearings and gears, repair of electric motors or
other press fit parts.

 10 ton hydraulic cylinder with 152 mm stroke. Longer stroke cylinders available on request
 Press plate set and bushing allows for greater pressing flexibility
 Steel frame provides maximum strength and rigidity
 Press bed has multiple working positions
 2 speed hand pump with force gauge and 2 metre hose set

Note – DPR-15R air/hydraulic power unit with remote pendant can also be used to operate the HP­10 press.

Special skill, knowledge and training may be required for a specific task and the product may not be
suitable for all jobs. The user must ultimately make the decision regarding suitability of the product
for any given task and assume the responsibility of safety for all in the work area. Contact a Durapac
representative if you are unsure of your bench press’ suitability for a particular application.

2.0 Receiving Instructions

It is recommended prior to use that an inspection be done by qualified personnel and that any
missing or damaged parts, decals, warning/safety labels or signs are replaced with Durapac
authorised replacement parts only. Any bench press that appears to be damaged in any way, is
worn, leaking or operates abnormally should be removed from service immediately until such time
as repairs can be made. Any bench press that has been or suspected to have been subject to a shock
load should be removed from service immediately until inspected by a Durapac authorised service
centre. Owners and operators of this equipment should be aware that the use and subsequent
repair of this equipment may require specialised training and knowledge.

3.0 Safety

Save these instructions. For your safety, read and understand the information contained within. The
owner and operator should have an understanding of this product and safe operating procedures
before attempting to use this product. Instructions and safety information should be conveyed in the
operator's native language before use of this product is authorised. Make certain that the operator
thoroughly understands the inherent dangers associated with the use and misuse of the product. If
any doubt exists as to the safe and proper use of this product as outlined in this factory authorised
manual, remove from service immediately.

Instruction Manual

 Do NOT handle pressurised hoses. Escaping oil under pressure can penetrate the skin

causing serious injury. If oil is injected under the skin, see a doctor immediately

 Stay clear of loads supported by hydraulics. A cylinder, when used as a load lifting

device, should never be used as a load holding device. After the load has been raised
or lowered, it must always be supported mechanically

WARNING:

 The system operating pressure must not exceed the pressure rating of the lowest

rated component in the system. Install pressure gauges in the system to monitor
operating pressure. It is your window to what is happening in the system

 Always wear appropriate personal protective equipment (PPE) when operating

hydraulic equipment. The operator must take precaution against injury due to failure
of the tool or work piece(s)

 Do NOT hold or stand directly in line with any hydraulic connections while pressurising

 Do NOT attempt to disconnect hydraulic connections under pressure. Release all line

pressure before disconnecting hoses

 All personnel must be clear before lowering load or depressurising the system

 Do NOT attempt to lift a load weighing more than the capacity of the cylinder

IMPORTANT:

 If at any stage, the safety related decals become hard to read, these must be replaced

 Minimum age of the operator must be 18 years. The operator must have read and

understood all instructions, safety issues, cautions and warnings before starting to
operate the equipment. The operator is responsible for this activity towards other
persons

 Do NOT lift hydraulic equipment by the hoses or couplers. Use the carrying handle or

other means of safe transport

 Hydraulic equipment must only be serviced by a qualified hydraulic technician. For

repair service, contact the Durapac authorised service centre in your area. To protect
your warranty, use only high quality hydraulic oil

CAUTION:

 KEEP HYDRAULIC EQUIPMENT AWAY FROM FLAMES AND HEAT. Hydraulic fluid can

ignite and burn. Excessive heat will soften packings and seals, resulting in fluid leaks.
Heat also weakens hose materials and packings. For optimum performance do not
expose equipment to temperatures of 65°C (150°F) or higher. Protect all equipment
from weld spatter

 No alteration should be made to this device

3.1 Hydraulic Presses

 Work pieces must be well supported and aligned so when pressure is exerted; parts

being pressed do not slip out or break

Instruction Manual

 To prevent accidental slippage, do not place work pieces on the press bed, or apply

hydraulic force until all bolster pins are in place and all tension has been removed
from the bolster lift cables

 Do NOT overload equipment. Overloading can cause equipment failure and possible

personal injury. The presses are designed for a maximum pressure of 700 bar

 Do NOT stress adapters beyond their capacities. Any pushing or pulling adapters used

with this press must have a maximum tonnage rating equal to, or higher than, the
maximum tonnage rating of the press, or breakage can occur

 It is impossible for Durapac to provide practical “all purpose” shielding because this is

a general all-purpose press that can be used in many different applications. The owner
of the press must supply shielding that is practical and necessary for each application.
Some safety can be provided by wrapping the piece in a protective blanket before
applying pressure

3.2 Hydraulic Hoses & Fluid Transmission Lines

 Avoid short runs of straight line tubing. Straight line runs do not provide for

expansion and contraction due to pressure and/or temperature changes

 Reduce stress in tube lines. Long tubing runs should be supported by brackets or

clips. Before operating the pump, connections should be tightened securely and
leak-free. Over tightening can cause premature thread failure or high pressure
fittings to burst

 Should a hydraulic hose ever rupture, burst or need to be disconnected,

immediately shut off the pump and release all pressure. Never attempt to grasp a
leaking pressurised hose with your hands. The force of escaping hydraulic fluid can
inflict injury

 Do NOT subject the hose to potential hazard such as fire, sharp objects, extreme

heat or cold or heavy impact

 Do NOT allow the hose to kink, twist, curl, crush, cut or bend so tightly that the fluid

flow within the hose is blocked or reduced. Periodically inspect the hose for wear

 Hose material and coupler seals must be compatible with the hydraulic fluid used.

Hoses also must not come in contact with corrosive materials such as battery acid,
creosote-impregnated objects and wet paint. Never paint a coupler or hose

FAILURE TO HEED THESE WARNINGS MAY RESULT IN PERSONAL INJURY AS WELL AS PROPERTY DAMAGE.

4.0 Installation

Locate the press in an isolated area, or shield the press to minimize danger to others. Hydraulic

pressure can cause materials to break, possibly resulting in personal injury

Do NOT adjust safety valve pressure – safety valve pressure is set at 700 bar

4.1 Familiarise yourself with the details and illustrations in this owner’s manual. Know your

bench press, its limitations and how it operates before attempting to use. If in doubt,
contact a Durapac representative.
