manual, remove from service immediately.

DANGER:

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

WARNING:

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)

IMPORTANT:

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

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

4.0 Installation

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

Know your hydraulic cutter, its limitations and how it operates before attempting to

use. Refer to the specification table below or if in doubt, contact a Durapac

representative.

4.2 Check oil level in reservoir before operating cutter.

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 hydraulic cutter be required, please

follow the steps in 6.3 –Bleeding Air from the System in the Maintenance Section.

5.0 Operation

IMPORTANT:

The maximum cutting capacity of this tool includes the thickness of the cable covering.

Keep this in mind when selecting the appropriate cable to use. If in doubt, use another

tool to cut away the cable covering before commencing cutting with this tool

Only attempt to cut cables which fit the tool specifications. No other materials are to

be cut

5.1 Before Operation

5.1.1 Make sure all parts of the product are clean, without rust or loose parts.

5.1.2 Check that no leakage occurs while the tool is resting or while the product is

being tested without cables.

5.2 Operation

Stop operating immediately in the case of any abnormalities

5.2.1 Release the hydraulic fluid pressure and retract the piston before opening

the tool head. To release the pressure; pull out the moving handle and

rotate it clockwise. Push down the moving handle. Once the piston returns

to its starting position the product is ready to operate.

6.0 Maintenance

IMPORTANT:

Check oil level regularly and make sure the reservoir is full

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 cutter. 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

Tools with worn or damaged blades may cause property damage or even personal

injury

The hydraulic relief valve pressure should only be adjusted by a Durapac

representative

Maintenance is required when wear or leakage is noticed. Periodically inspect all

components to detect any problem that may require service and maintenance.

Keep the tool head free of dirt and metal chips. Use a lubricant to clean the tool when

necessary.

Routine application of rust preventative oil to the product is needed. Avoid bringing the tool

into contact with water or solvents.

6.1.1.3 Ensure that all components are tight and that the blade opens and

closes smoothly.

6.1.2 Moving Blade Replacement

6.1.2.1 Advance the lower blade until the connecting pin is visible on the

main piston.

6.1.2.2 With the tool head open, remove the connecting pin to unfasten the

blade.

6.1.2.3 Insert the new blade and reassemble the connecting pin to secure

the blade in place.
