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.
DANGER:
To avoid personal injury keep hands and feet away from work area during operation
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 blocked 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 protective gear 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 Toe Jacks
Do NOT exceed the rated capacity of the jack or any equipment in the system
Do NOT tamper with the adjustment of the jacks internal relief valve screw. To do so
may cause the jack to fail
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 block 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
Do NOT lift a load on the end of the toe. Fully engage the load with the toe and where
practical ensure that the top of the vertical face “head-toe” attachment is also
engaged with the load.
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-toe attachment
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.

4.2 Check oil level in reservoir before operating the jack
4.2.1 Open release valve with the handle (not more than two counter-clockwise
turns) and press down on the head-toe attachment to ensure the piston is
fully down.
4.2.2 Remove the oil filler plug.
4.2.3 The oil should be level with the bottom of the filler hole. Adjust level as
necessary and replace plug.
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.
5.0 Operation
IMPORTANT:
Do NOT lift a load on the end of the toe. Fully engage the load with the toe and
where practical ensure that the top of the vertical face “head-toe” attachment is
also engaged with the load
When lifting by the toe, wedge the head of the jack on the load to avoid bending
the column
5.1 Raising the Jack
5.1.1 Close the release valve (clockwise) with the jacking handle.
5.1.2 Position the jack so that the toe or head is under the load point. Do not use
the handle in the release valve to move the jack. Damage will occur.
5.1.3 Pump the jacking lever in an up and down motion.
5.2 Lowering the Jack
5.2.1 Check beneath the load for any obstructions and remove any mechanical
supports.
5.2.2 Slowly open the release valve (counter clockwise) with handle. Control the
rate of descent by smoothly opening or closing the valve.
5.2.3 To stop the jack from lowering the load, close the release valve (clockwise).
5.2.4 Note: The release valve should not be closed abruptly (except in an
emergency) since this shock loads the hydraulic system.
5.2.5 After use, the jack should be stored with the load piston and pump piston
both fully retracted.

6.0 Maintenance
IMPORTANT:
Check oil level regularly
Use only good quality hydraulic fluid. Do NOT use brake fluid, transmission fluid,
turbine oil, motor oil, alcohol, glycerine etc. Use of anything other than good quality
hydraulic oil will void warranty and damage the jack, hose, and application. We
recommend Durapac Hydraulic Oil or equivalent
Equipment must only be serviced by a qualified hydraulic technician. For repair service,
contact your local Durapac authorised service centre
The greatest single cause of failure in hydraulic systems is dirt; keep the jack clean and well
lubricated to prevent foreign matter from entering the system. If the jack has been exposed
to rain, snow, sand or grit, it must be cleaned before and after each use.
Maintenance is required when wear or leakage is noticed. Periodically inspect all
components to detect any problem that may require service and maintenance.
6.1 Adding Hydraulic Fluid
WARNING: Always add oil with cylinders fully retracted (or extended, if pull cylinders)
or the system will contain more oil than the reservoir can hold
6.1.1 Open release valve with handle (not more than two counter-clockwise turns).
6.1.2 Press down on head to ensure piston is fully down.
6.1.3 Remove the oil filler plug.
6.1.4 Use a small funnel to fill the reservoir level with the bottom of the filler hole.
6.1.5 Bleed air from system if necessary.
6.1.6 Close the release valve (turn clockwise).
6.1.7 Wipe up any spilled fluid and reinstall the oil filler plug.
6.2 Bleeding Air from the System
6.2.1 Repeat Steps 6.1.1 to 6.1.4 (above), if required.
6.2.2 Actuate the pump handle 12 times. Air will be released into the jack reservoir.
6.2.3 Recheck oil level after removing air.
6.2.4 Close the relief valve (turn clockwise).
6.3 Changing Hydraulic Fluid
