1. Make sure Power Drive is unplugged and the direc-
tional switch is set to the OFF position (Figure 3) .
2. Clean the speed chuck jaws with a wire brush.
3. Inspect the jaw inserts for excessive wear. Refer to the
Maintenance Instructions if they need to be replaced.
NOTE! For plastic and coated work pieces, special jaw
inserts (Part No. 97365) should be used to pre-
vent damaging the workpiece.
4. Make sure the foot switch is present and attached to
the Power Drive (Figure 3).
Do not operate the Power Drive without a
WARNING
foot switch.
5. Inspect the power cord and plug for damage. If the
plug has been modified, is missing the grounding
pin or if the cord is damaged, do not use the Power
Drive until the cord has been replaced.
6. Inspect the Power Drive for any broken, missing,
misaligned or binding parts as well as any other con-
ditions which may affect the safe and normal opera-
tion of the machine. If any of these conditions are pre-
sent, do not use the Power Drive until any problem
has been repaired.
7. Lubricate the Power Drive spindle bearings if neces-
sary according to the Maintenance Instructions.
8. Use tools and accessories that are specifically
designed for your Power Drive and meet the needs of
your application. The correct tools and accessories
allow you to do the job successfully and safely.
Accessories suitable for use with other equipment
may be hazardous when used with this Power Drive.
9. Clean any oil, grease or dirt from all handles and
controls. This reduces the risk of injury due to a tool or
control slipping from your grip.
Inspect the cutting edges of your tools and dies. If
necessary, have them replaced prior to using the
Power Drive. Dull or damaged cutting tools and
dies can lead to binding, tool breakage and poor
quality threads.
10. Clean metal shavings and other debris from the chip
tray of the 418 Oiler. Check the level and quality of the
thread cutting oil. Replace or add oil if necessary.
NOTE! Thread cutting oil lubricates and cools the threads
during the threading operation. A dirty or poor
grade cutting oil can result in poor thread quality.
