OPERATION
The tool is provided with six Bending Formers.
This enables the following sizes of British Standard Pipe, to BS1387, to 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 former is used, the quality of bend will be severely compromised.
With the pipe resting i n the former , and with the ram in its lowest position, (open the
hydraulic valve by turning it anticlockwise), secure the guide rollers in place using the
R Clip s (see parts diagram).
ALWAYS ensure the pipe is located securely and square in 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. ThIs allows the work to be removed.
To remove the former 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 former.
