For Spare Parts and Service,please contact your nearest dealer, or CLARKE International,
on one of the following numbers.
Thank you for purchasing this CLARKE Hydraulic Pipe Bending Kit, which is designed for bending STEEL
PIPE ONLY, either galvanised or black finish.
IMPORTANT: This tool is NOT designed to bend thin wall tube - copper for example, and this should not
be attempted. This tool benefits from being able to be used on its side, unlike many other types.
Please read this leaflet thoroughly before use, to familiarise yourself with its operation, so that it may be
used properly in order to provide you with long and satisfactory service.
GUARANTEE
This CLARKE product is guaranteed against faulty manufacture for a period of 12 months from the date of
purchase. Please keep your receipt as proof of purchase.
This guarantee is invalid if the product is found to have been abused or tampered with in any way, or not used
for the purpose for which it was intended.
Faulty goods should be returned to their place of purchase, no product can be returned to us without prior permission.
This guarantee does not effect your statutory rights.
METHOD OF USE
The tool is provided with six Bending Dies or Formers, in order that the following sizes of British Standard Pipe, to
BS1387, may be bent to any angle up to 180 degrees.
1/2 , 3/4, 1, 1-1/4, 1-1/2, and 2 inches
Consult the chart below to ensure the correct die for the corresponding pipe is used. If the wrong die is used, the
quality of bend will be severely compromised.
With the pipe resting on the die, and with the ram in its lowest position, (open the hydraulic valve by turning it
anticlockwise), secure the guide rollers in place using the Hitch Pin (see parts diagram).
ALWAYS ensure the pipe is sitting firmly and squarely on the die,
Close the hydraulic valve by turning it clockwise fully, then pump the operating lever gently.
NOTE: For best results, bend the pipe progressively. Set the guide rollers wide apart to begin with, bringing them
closer together as the degree of bend increases.
When completed, open the hydraulic valve, thus allowing the work to be removed.
To remove the Die from the work, a short sharp tap with a hammer and brass drift should be all that is required. TAKE
CARE when removing...NEVER hammer directly on the edges of the Die.
MAINTENANCE
This tool requires no maintenance except for keeping it clean. Always inspect before each use to ensure no welds
are cracked or broken, and that the tool is in good general condition. If it is damaged or if in doubt as to its
serviceability, consult your CLARKE dealer immediately.
ALWAYS store the tool with the ram in its lowest position, IN AN UPRIGHT POSITION - DO NOT lay on its side as air
could enter the system resulting in poor performance and the need to bleed before putting to use once again.
If the ram fails to operate satisfactorily, it should be bled as follows: With the ram in its vertical position, close the
release valve at the base of the ram unit (turn it clockwise), then remove the rubber bung on the upper part of the
cylinder. Pump the handle several times to expel all air, then replace the rubber bung.
