WARNING

Some dust created by power sanding, sawing, grinding,
drilling, and other construction activities contains chemi­cals known to the State of California to cause cancer,
birth defects or other reproductive harm. Some examples
of these chemicals are:

• Lead from lead-based paints.

• Crystalline silica from bricks, cement, and other
masonry products.

• Arsenic and chromium from chemically treated
lumber.

Your risk from these exposures varies, depending on
how often you do this type of work. To reduce your expo­sure to these chemicals: work in a well ventilated area,
and work with approved safety equipment, such as those
dust masks that are specially designed to filter out micro­scopic particles.

Safety Instructions For Power Tools

SECTION 1: SAFETY

5. KEEP CHILDREN AND VISITORS
AWAY. All children and visitors should be

kept a safe distance from work area.

6. MAKE WORKSHOP CHILD PROOF with

padlocks, master switches, or by removing
starter keys.

7. DO NOT FORCE TOOL. It will do the job

better and safer at the rate for which it was
designed.

8. USE RIGHT TOOL. Do not force tool or

attachment to do a job for which it was not
designed.

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. DO NOT 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.

For Your Own Safety Read Instruction

Manual Before Operating This Equipment

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.

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.

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.

13. DO NOT 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. USE RECOMMENDED ACCESSORIES.

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

Safety Instructions For Power Tools

16. REDUCE THE RISK OF UNINTENTION­AL STARTING. On machines with mag-

netic contact starting switches there is a
risk of starting if the machine is bumped or
jarred. Always disconnect from power
source before adjusting or servicing. Make
sure switch is in OFF position before recon­necting.

17. MANY WOODWORKING TOOLS CAN
“KICKBACK” THE WORKPIECE toward

the operator if not handled properly. Know
what conditions can create “kickback” and
know how to avoid them. Read the manual
accompanying the machine thoroughly.

18. CHECK DAMAGED PARTS. Before fur-

ther 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. Do not

leave tool until it comes to a complete stop.

20. NEVER OPERATE A MACHINE WHEN
TIRED, OR UNDER THE INFLUENCE OF
DRUGS OR ALCOHOL. Full mental alert-

ness is required at all times when running
a machine.

21. NEVER ALLOW UNSUPERVISED OR
INEXPERIENCED PERSONNEL TO
OPERATE THE MACHINE. Make sure

any instructions you give in regards to
machine operation are approved, correct,
safe, and clearly understood.

22. IF AT ANY TIME YOU ARE EXPERIENC­ING DIFFICULTIES performing the intend-

ed operation, stop using the machine!
Then contact our service department or
ask a qualified expert how the operation
should be performed.

-4- G7945/46 Radial Drill Press

1. ALWAYS OPERATE YOUR DRILL PRESS AT SPEEDS that are appropriate for the drill bit size

and the material that you are drilling.

2. FEED THE DRILL BIT EVENLY INTO THE WORKPIECE. Back the bit out of deep holes and clear

the chips with a brush after you have turned the machine off.

3. MAKE SURE THE DRILL BIT YOU ARE USING IS TIGHTENED PROPERLY. Use only round,

hex or triangular shank drill bits.

4. NEVER DO MAINTENANCE OR CHANGE SPEEDS WITH THIS MACHINE PLUGGED IN.

5. NEVER USE TOOLS THAT ARE IN POOR CONDITION. Cutting tools that are dull or damaged

are difficult to control and may cause serious injury.

6. NEVER DRILL SHEET METAL UNLESS IT IS CLAMPED SECURELY TO THE TABLE.

7. WORK SHOULD BE POSITIONED IN SUCH A WAY AS TO AVOID DRILLING INTO THE
TABLE.

8. A FACE SHIELD USED WITH SAFETY GLASSES IS RECOMMENDED.

9. ALWAYS CLAMP WORKPIECE SECURELY TO TABLE BEFORE DRILLING. Never hold a

workpiece by hand while drilling.

10. HABITS – GOOD AND BAD – ARE HARD TO BREAK. Develop good habits in your shop and

safety will become second-nature to you.

11. REMOVE ADJUSTING KEYS AND WRENCHES. Before turning the machine on, make it a habit

to check that all adjusting keys and wrenches have been removed.

Additional Safety Instructions For Drill Presses

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. Use
this and other machinery with caution and
respect. Failure to do so could result in
serious personal injury, damage to equip­ment or poor work results.

110V Operation

SECTION 2: CIRCUIT REQUIREMENTS

A 10-amp fuse or circuit breaker should be used
when fusing this drill press. Circuits breakers
rated any higher may not be adequate to protect
the circuit from power surges.

If you find it necessary to use an extension cord
with the Model G7945/7946, make sure the cord
is rated Hard Service (grade S) or better. Refer to
the chart in the standard safety instructions to
determine the minimum gauge for the extension
cord. The extension cord must also contain a
ground wire and plug pin.

Extension Cords

Grounding

In the event of an electrical short, grounding
reduces the risk of electric shock by providing
electric current a path of least resistance. This
tool is equipped with a power cord having an

equipment-grounding conductor. See Figure 1.

The outlet must be properly installed and ground­ed in accordance with all local codes and ordi­nances.

The Model G7945/46 is wired for 110V, single
phase operation only. The

1

⁄2 HP motor will safely
draw 5 amps at 110V. If you operate this machine
on any circuit that is already close to its capacity,
it might blow a fuse or trip a circuit breaker.
However, if an unusual load does not exist and a
power failure still occurs, contact a qualified elec­trician or our service department.

Figure 1. Typical 110V 3-prong plug and outlet.

Figure 1A. Do not remove grounding pin.

This equipment must be
grounded. Verify that any
existing electrical outlet
and circuit you intend to
plug into is actually
grounded. Under no cir­cumstances should the
grounding pin from any
three-pronged plug be
removed or serious injury
may occur.
