Safety Instructions For Power Tools
WARNING
14. MAINTAIN TOOLS WITH CARE. Keep
tools sharp and clean for best and safest
performance. Follow instructions for lubri-
cating 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 posi-
tion before plugging in.
17. USE RECOMMENDED ACCESSORIES.
Consult the owner’s manual for recom-
mended 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 mov-
ing parts, breakage of parts, mounting, and
any other conditions that may affect its oper-
ation. A guard or other part that is damaged
should be properly repaired or replaced.
19. DIRECTION OF FEED. Feed work into a
blade or cutter against the direction of rota-
tion of the blade or cutter only.
20. NEVER LEAVE TOOL RUNNING UNAT-
TENDED. TURN POWER OFF. Don’t leave
tool until it comes to a complete stop.
9. USE PROPER EXTENSION CORD. Make
sure your extension cord is in good condi-
tion. When using an extension cord, be
sure it is rated Hard Service (grade S) or
better. Conductor size must be 16 A.W.G.
for cords up to 100 feet in length. An under-
sized 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 Gage for extension
cord: 12 A.W.G. 50ft
10 A.W.G. 100ft
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 cov-
ering 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 safe-
ty 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 footing
and balance at all times.

Additional Safety Instructions For Planers
WARNING
CAUTION
No list of safety guidelines can be com-
plete. 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 person injury, damage to equip-
ment or poor work results.
WARNING
Like all power tools, there is danger asso-
ciated with the Model G1021 15" Planer.
Use the tool with respect and caution to
lessen the possibility of mechanical dam-
age or operator injury. If normal safety pre-
cautions are overlooked or ignored.
Serious personal injury may occur.
WARNING
Always wear ANSI-approved safety glasses
or goggles and hearing protection when
operating equipment. Do not allow visitors
into your workshop when testing or operat-
ing equipment unless similarly equipped.
Serious personal injury may occur.
1. Ensure that the machine sits firmly on the
floor before use. Any “wobbles” must be
corrected by shimming or blocking before
operation.
2. This machine is not designed to process
any other material except wood.
3. Never position fingers or thumbs near the
infeed roller.
4. Long stock should always be fully support-
ed by some type of support fixture.
5. Do not operate planer with dull or damaged
knives.
6. Ensure that the planer is properly adjusted
before using.
7. Do not remove excessive amounts of
wood in a single pass.
8. Inspect your stock before planing. Reject
stock with defects and foreign material.
9. Do not attempt to remove jams until power
is disconnected and all moving parts have
come to a complete stop.
10. Provide adequate infeed and outfeed
space for operating the planer.
11. Do not plane wood less than 12" long and
1⁄4" thick.
12. Do not plane lumber with loose knots or
knots that may become loose during
planing.

-8- G1021 15" Planer
220V Operation
SECTION 2: CIRCUIT REQUIREMENTS
The G1021 Planer motor is wired to operate at
220V only. A cordset without a 220V plug is
included with the Model G1021. Plugs and recep-
tacles can be purchased at your local hardware
store or home center. When connecting to 220V,
ensure that the electrical circuit is in fact a 220V
circuit. Contact your local electrical contractor if
uncertain about converting to 220V operation.
When operating at 220V, we recommend using a
NEMA-style 6-15 plug and outlet as depicted in
Figure 1. You may also “hard-wire” the planer
directly to your panel, provided you place a dis-
connect switch near the machine. Check the
electrical codes in your area for specifics on
wiring requirements.
Under normal load, the Model G1021 draws
about 12 amps. We recommend a 15-amp circuit
or a 20-amp slow-blow fuse. A circuit rated any
higher will not adequately protect the motor.
Equipment returned to us for service that shows
evidence of being over-fused will be repaired or
replaced totally at the customer’s expense,
regardless of the present warranty status.
Fusing If used, extension cords must be rated hard ser-
vice – grade S – or better. Conductor size must
be 12 AWG for cords up to 50 feet in length. Your
extension cord must also contain a ground wire
and plug pin. To ensure safe and dependable
machine performance, inspect cords frequently
for wear or damage. Replace or repair the cord
immediately if evidence of damage is apparent.
Extension Cords
Grounding
WARNING
This equipment must be grounded. Please
ensure that this machine is continuously
grounded from the motor to the machine frame
and then to a known ground. Verify that any
existing electrical outlet and circuit you intend
to plug into is actually grounded. If it is not, it
will be necessary to run a separate 12 A.W.G.
copper grounding wire from the outlet to a
known ground. Under no circumstances should
the grounding pin from any three-pronged plug
be removed. Serious injury may occur.
Figure 1. NEMA 6-15 220V/15A connector.
In the event of an electrical short, grounding
reduces the risk of electric shock by providing a
path of least resistance to disperse electric cur-
rent. This tool is equipped with a power cord hav-
ing an equipment-grounding conductor. The out-
let must be properly installed and grounded in
accordance with all local codes and ordinances.

Unpacking
The bandsaw is shipped from the factory in a
carefully packed carton. If you find the machine to
be damaged after you’ve signed for delivery and
the truck and driver are already gone, you will
need to file a freight claim with the carrier. Save
the containers and all packing materials for
inspection by the carrier or their agent. Without
the packing materials, filing a freight claim can be
difficult. If you need advice regarding this situa-
tion, please call us immediately.
WARNING
The G1021 is a heavy machine with a 475 lb.
shipping weight. DO NOT over-exert your-
self while unpacking or moving your
machine – get assistance. In the event that
your planer must be moved up or down a
flight of stairs, be sure that the stairs are
capable of supporting the combined weight
of people and the machine. Failure to use
care while assembling or moving could
result in serious personal injury.
