8. Insert expander in tube as required.
9. Completely depress throttle valve trigger lever to find
forward speed. When preset torque has been reached, drive will
dis-engage and mandrel will stop rotating; release throttle
valve lever when this occurs.
10.Fully squeeze reverse valve trigger into reverse position
(depressed). Valve locks in this position and only releases when
throttle valve trigger lever is released. Depress throttle valve
trigger lever to reverse drive and back expander out of tube.
Note: There must be a positive resistance to turning on the tool
spindle of 5-6 inch— pounds in the reverse direction before
drive will reengage and set latching pawls for rotation in the
forward direction.
11. Measure tube’s actual inside diameter. If the amount of ex-
pansion is not sufficient, adjust torque control to a slightly
higher value and roll the next tube.
12. When desired expansion has been attained, maintain the set-
ting and roll the entire lot. Reroll all trial tubes which were
not completely expanded.
13. Always record settings used and tube data such as tube 0.D.
and gauge with tube sheet thickness for future reference.
Amount of oil used will vary with tool usage but daily filling
of handle oil reservoir should normally be adequate. Check that
a fine mist of oil is always present in the air which passes
out through exhaust deflector holes. For continuous and heavy
tool usage, it is preferable to use an automatic air line lu-
bri-cator. For this purpose, the Wilson Air Filter-Lubricator
Unit (Cat. #8596 for 3/8” lines) is recommended. This unit com-
bines an automatic lubricator with an efficient air filter.
Caution: To inhibit rust during tool storage be sure a liberal
amount of oil has been introduced into valve and air motor.
Also be sure operat-ing air moisture content is kept at a mini-
mum. Compressor after coolers, air line traps, water separators
and use of rust-inhibiting lubricat-ing oil all help. Thor-
oughly clean or replace any rusted parts found during service
checks.
