17. Pull the vent on the reservoir cap open
(Figure 6). Do
not thread with the vent closed. This will reduce
coolant flow and could cause die chipping and poor
quality threads.
Figure 6 – Reservoir Vent Open
18. Move the die head down into the threading position.
Depress and hold the foot switch and look for coolant
flow between die 3 and 4 on the die head
(See Figure
7). It may take up to 10 seconds for the coolant to start
flowing if the die head has been off the machine or sat
for an extended time. Coolant should be dripping at a
rate of at least 1 drop per second. Too high a drip rate
wastes coolant, while too low a drip rate can cause die
chipping, poor quality thread and high thread temper-
atures.
19. To adjust the coolant drip rate, while depressing the
foot switch, use a flat blade screwdriver to turn the
needle pin on the die head
(see Figure 7). Clockwise
needle pin rotation decreases drip rate, while coun-
terclockwise rotation increases drip rate
Figure 7 – Adjusting Coolant Drip Rate
20. Move the die head away from the operator. Die head
position turns the coolant flow on and off while ma-
chine is running. To conserve coolant, only place die
head down in the threading position when threading or
transporting.
21. Move the ON/OFF switch to the OFF position, and
with dry hands unplug the machine.
