9. USE PROPER EXTENSION CORD. Make
sure your extension cord is in good condition. Conductor size should be in accordance with the chart below. The amperage
rating should be listed on the motor or tool
nameplate. An undersized cord will cause a
drop in line voltage resulting in loss of
power and overheating. Your extension
cord must also contain a ground wire and
plug pin. Always repair or replace extension cords if they become damaged.
Minimum Gauge for Extension Cords
10. WEAR PROPER APPAREL. Do not wear
loose clothing, gloves, neckties, rings,
bracelets, or other jewelry which may get
caught in moving parts. Non-slip footwear
is recommended. Wear protective hair covering to contain long hair.
11. ALWAYS USE SAFETY GLASSES. Also
use face or dust mask if cutting operation is
dusty. Everyday eyeglasses only have
impact resistant lenses, they are NOT safety glasses.
12. SECURE WORK. Use clamps or a vise to
hold work when practical. It’s safer than
using your hand and frees both hands to
operate tool.

mounting, and any other conditions that
may affect its operation. A guard or other
part that is damaged should be properly
repaired or replaced.

Additional Safety Instructions For The G2891
No list of safety guidelines can be complete.
Every shop environment is different. Always
consider safety first, as it applies to your
individual working conditions. Failure to do
so could result in serious personal injury,
damage to equipment or poor work results.
This equipment has the potential to propel
debris into the air which can cause eye
injury. Always wear safety glasses or goggles when operating equipment. Everyday
glasses or reading glasses only have
impact resistant lenses, they are not safety
glasses. Be sure your safety glasses meet
American National Standards Institute
(ANSI) standards.
Like all power tools, there is danger associated with the Model G2891 Lathe Copy
Attachment. Accidents are frequently
caused by lack of familiarity or failure to
pay attention to the tool or your work. Use
this tool with respect and caution to lessen
the possibility of operator injury. If normal
safety precautions are overlooked or
ignored serious personal injury may occur.
7. Before any copying operation, ensure
that the headstock and tailstock of your
lathe are centered on the same axis.
8. While working, position yourself so you
are within easy reach of all lathe and
Copy Attachment controls.
9. Keep base lubricated to ensure smooth
carriage movement during copying. DO
NOT lubricate the cable, it is friction
operated.
10. Do not make any adjustments to the
lathe or copy attachment while the lathe
is operating. If adjustments are necessary, turn the lathe off, unplug the power
cord and wait for the moving parts to
stop.
11. Habits - good and bad - are hard to
break. Develop good habits and safety
will become second-nature.
1. Before turning your lathe on, ensure
that the cutting tool is well away from
the turning square. Ensure that the turning square will rotate freely.
2. Make sure the workpiece and the tem-
plate or master spindle are securely
mounted.
3. Always start the lathe at its slowest
speed.
4. Maintain minimal play in the guide cable
and carriage.
5. To prevent excessive vibration, don’t
force the cutting tool or take too big a
cut in one pass. Recommended maximum cut is
1
⁄16"
6. Make sure cable path is unobstructed at
all times.
