A tube bender is used to prevent

tubing from kinking or flattening out at the desired bend. To use a bender,

push it over the tube until the center portion of the bender is centered

over the point in the tube where the bend is to be made. The tube can then

be bent by hand to the desired radius. Pull the bender from the tube after

bending.

d. Use of Pullers.

(1) General.

Place a puller firmly in position and secure it if

locking devices are part of the puller. Make certain the puller will not

slip off suddenly while under strain. Check all gripping edges and threads

of a puller for damage before using it.

Use the proper size wrench for

turning the pressure screw or nut to avoid rounding the corners of the nut

or of the screw head. Use the proper size puller for the job.
