Operating Procedure
WARNING
Operator should be thoroughly familiar
with preceding Safety Precautions before
attempting to operate this equipment.
1. Mount machine on a stand or bench as instructed.
2. Pour one gallon of Thred-O-Matic oil into the oil
sump. Thred-O-Matic oil is a special oil designed
to stand up under the high speed operation of
this machine. Other oils will have a tendency
to break down, causing excessive die wear and
poor thread quality. If Thred-O-Matic oil is not
available, use a high quality equivalent dark,
sulphur-base thread cutting oil. Oil pump is self-
priming; therefore no priming is needed.
3. For first 10 days of operation, lubricate the spindle
bearings every 4 hours with SAE 30 lubricating oil.
4. Your COLLINS 22A is equipped with two electrical
switches; a safety foot switch, and a
THREAD/OFF/RELEASE (T.O.R.) switch . COLLINS

right- and left-hand 22As have a third switch; a
right- and left-hand directional switch. The func-
tion of these switches are as follows: The safety
foot switch is designed to provide the operator
with a rapid method of stopping electrical power
to the machine if an emergency should occur.
Also, it insures that the machine cannot be oper-
ated unless the operator is in proper position.
The THREAD/OFF/RELEASE switch is the main
operat ing switch. The THREAD position closes the
jaws and rotates the spindle. The OFF position
stops the machine. The REVERSE position opens
the jaws. The REVERSE position is spring-loaded
to return to the OFF position. The right- and left
hand switch changes the direction of the motor
and therefore the direction of the spindle.
5. After making proper electrical connection, step
on foot switch and move the THREAD/OFF/
RELEASE switch to THREAD position in order to
check oil flow. When die head is in the down
position, oil will flow through the die head. If up,
oil will flow from bypass pressure relief valve.
