Manual Before Operating This Equipment

The purpose of safety symbols is to attract your attention to possible hazardous conditions. This
manual uses a series of symbols and signal words which are intended to convey the level of
importance of the safety messages. The progression of symbols is described below. Remember
that safety messages by themselves do not eliminate danger and are not a substitute for proper
accident prevention measures.

Indicates an imminently hazardous situation which, if not
avoided, WILL result in death or serious injury.

Indicates a potentially hazardous situation which, if not
avoided, COULD result in death or serious injury.

Indicates a potentially hazardous situation which, if not
avoided, MAY result in minor or moderate injury. It may also
be used to alert against unsafe practices.

This symbol is used to alert the user to useful information

about proper operation of the equipment.

Safety Instructions For Power Tools

1. KEEP GUARDS IN PLACE and in working

order.

2. REMOVE ADJUSTING KEYS AND
WRENCHES. Form habit of checking to

see that keys and adjusting wrenches are
removed from tool before turning on.

3. KEEP WORK AREA CLEAN. Cluttered
areas and benches invite accidents.

4. DON’T USE IN DANGEROUS
ENVIRONMENT. Don’t use power tools in

damp or wet locations, or where any flam­mable or noxious fumes may exist. Keep
work area well lighted.

5. KEEP CHILDREN AND VISITORS AWAY.

All children and visitors should be kept a
safe distance from work area.

6. MAKE WORK SHOP CHILD PROOF with

padlocks, master switches, or by removing
starter keys.

Safety Instructions For Power Tools

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

LENGTH
AMP RATING 25ft 50ft 100ft

0-6 18 16 16
7-10 18 16 14
11-12 16 16 14
13-16 14 12 12
17-20 12 12 10
21-30 10 10 No

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.

13. DON’T OVERREACH. Keep proper foot-

ing and balance at all times.

14. MAINTAIN TOOLS WITH CARE. Keep

tools sharp and clean for best and safest
performance. Follow instructions for lubri­cating and changing accessories.

15. DISCONNECT TOOLS before servicing

and changing accessories, such as blades,
bits, cutters, and the like.

16. REDUCE THE RISK OF UNINTENTIONAL
STARTING. Make sure switch is in off

position before plugging in.

17. USE RECOMMENDED ACCESSORIES.
Consult the owner’s manual for recom­mended accessories. The use of improper
accessories may cause risk of injury.

18. CHECK DAMAGED PARTS. Before fur­ther use of the tool, a guard or other
part that is damaged should be carefully
checked to determine that it will operate
properly and perform its intended func­tion. Check for alignment of moving parts,
binding of moving parts, breakage of parts,
mounting, and any other conditions that
may affect its operation. A guard or other
part that is damaged should be properly
repaired or replaced.

19. NEVER LEAVE TOOL RUNNING
UNATTENDED. TURN POWER OFF.

Don’t leave tool until it comes to a com­plete stop.

Additional Safety Instructions For The G2891

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

6. Make sure cable path is unobstructed at
all times.

⁄16"

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.

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.

-4-

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.

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.

Unpacking

Parts Inventory

This Wood Lathe Copy Attachment is shipped
from the manufacturer in a carefully packed

claim with the carrier. Save the containers and all
packing materials for possible inspection by the
carrier or its agent. Without the packing materials,
filing a freight claim can be difficult. If you need

assistance determining whether you need to file
a freight claim, or with the procedure to file one,
please contact our Customer Service.

When you are completely satisfied with the con­dition of your shipment, you should inventory its
parts.

After all the parts have been removed from the
carton, you should have:

Site Considerations Notes

FLOOR LOAD

Your G2891, when mounted to your wood lathe,
represents a large weight load in a small foot­print. Be sure that the floor in your work area is
adequately reinforced to support the weight of the
lathe and copy attachment.

WORKING CLEARANCES

Working clearances can be thought of as the
distances between machines and obstacles that
allow safe operation of every machine without
limitation. Ensure that your working area offers
plenty of room for free movement and a substan­tial amount of distance between you and others
that may be working in your shop space.

LIGHTING AND OUTLETS

Lighting should be bright enough to eliminate
shadows and prevent eye strain. Electrical cir­cuits should be dedicated or large enough to
handle combined motor amp loads of the lathe
and other machinery connected to that circuit.
Outlets should be located near each machine
so power or extension cords are not obstructing
high-traffic areas. Be sure to observe local elec­trical codes for proper installation of new lighting,
outlets, or circuits.

Make your shop “child safe”. Ensure that
your workplace is inaccessible to young­sters by closing and locking all entrances
when you are away. Never allow visitors in
your shop when assembling, adjusting or
operating equipment.
