1.0 Product Information

DURAPAC – Hydraulic Bottle Jacks are engineered to meet Industrial Standards for Performance and
Safety. The DBJ Series of bottle jacks are a premium range ideally suited to most industrial lifting
and pushing applications. Models from 10-20 ton feature an additional screw extension and most
can be used in both the vertical and horizontal positions. All jacks are repairable and seal kits are
available.

 All jacks have been designed for ease of use and handling
 Operating handle is included with all models
 Carbon steel base is automatically welded to ensure increased resistance to high pressure

and provide greater durability

 Chrome plated steel piston rod resists corrosion and extends life
 Internal stroke limiter prevents piston rod over-extension

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 bottle jack’s suitability for a particular application.

authorised replacement parts only. Any bottle jack 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 bottle jack 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.

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 Bottle Jacks

 Do NOT exceed the rated capacity of the jack or any equipment in the system

 Do NOT use in an unstable or hazardous position
 Always use the jack on solid and level surface that is capable of carrying the load. If

used to lift a vehicle, set the vehicle’s parking brake and chock the tyres

 Keep the load stable during lifting. An unstable load may cause the jack or load to slip
 Centre the load on the jack. Off centre loads can damage seals and cause hydraulic

failure

 Keep non-essential personnel at a safe distance when using the jack
 Do NOT carry the jack by the jacking lever
 Do NOT lift people or loads with people on them
 Ensure that the jack is undamaged and in good working order. Do not use the jack if it

is damaged

 Do NOT use the jack for any purpose other than that for which it is intended
 Keep the jack clean, particularly the head
 Do NOT operate the system with bent or damaged couplers or damaged threads
 Do NOT subject the jack and its components to shock loads
 Use only Durapac approved accessories and components

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

4.0 Installation

4.1 Familiarise yourself with the specifications and illustrations in this owner’s manual.

Know your bottle jack, its limitations and how it operates before attempting to use.
Refer to the specification chart below or if in doubt, contact a Durapac representative.

4.2 Check oil level in reservoir before operating the jack.

4.3 Remove air from the system – Air can accumulate in the hydraulic system during the

initial setup or after prolonged use, causing the cylinder to respond slowly or in an
unstable manner. Should removal of air from the jack be required, please follow the
steps in 6.2 – Bleeding Air from the System in the Maintenance Section.

4.4 Lubrication - Oil the pivots of the manual pump mechanism.
