The specifications, drawings and photographs in this manual represent the Model G1126, as supplied when the manual was prepared. However, owing to Grizzly’s policy of continuous improvement, changes to the Model G1126 may be made at any time with no obligation on the part of
Grizzly.
The information in this manual has been obtained from sources believed to be reliable and as up-todate as possible. While this manual is intended to be a good source for basic information, it is by no
means the last word on milling or metalworking. Instead, we have focused primarily on the proper
assembly and adjustment of the machine. We have also included some important safety measures
which we believe to be essential to this machine’s operation. Though most safety measures are generally universal, Grizzly cautions that each workshop is different and safety rules should be consid-
ered as they apply to your individual situation.
The Model G1126 is designed for highly-skilled individuals who have an understanding of metals and
machining. A strong knowledge of metalworking is essential for the proper use of the mill / drill. We
realize there are numerous kinds of cutters and specialized techniques used in metalworking. To list
all of the techniques necessary to operate a mill / drill correctly for specific applications would require
many volumes.
If you are not familiar with milling machines and their safe operation, we strongly suggest you obtain
as many books on the subject as you can. A visit to the local library, or time spent browsing through
back issues of machinist’s magazines will prove beneficial in gaining knowledge of mill / drill operations.
III. SAFETY RULES FOR ALL TOOLS
WARNING! As with all power tools, there is a certain amount of danger associated with the Model
G1126 Gear-Head Mill / Drill. Using the tool with respect and caution will considerably lessen the
possibility of mechanical damage or operator injury. However, if normal safety precautions are overlooked or ignored, injury to the operator or others in the area is possible.
There are certain applications for which this tool was designed. We strongly emphasize that this tool
should never be modified and/or used for any application other than that for which it was designed.
If you are confused about any aspect of this machine, do not use it until you have resolved any
questions you might have. The following are important safety rules for all tools:
1. KNOW YOUR POWER TOOL. Read the owner’s manual carefully. Learn the tool’s applications
and limitations, as well as its particular hazards.
2. KEEP GUARDS IN PLACE and in working order.
3. GROUND ALL TOOLS. If the tool is equipped with a three-prong plug, it should be plugged into
a three-hole grounded outlet. If an adapter is used to accommodate a two-prong receptacle, the
adapter plug must be attached to a known ground. Never remove the grounding prong.
4. REMOVE ADJUSTING KEYS AND WRENCHES. Make it a habit to ensure keys and adjusting
wrenches are removed from the machine before turning it on.

5. KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.
6. AVOID DANGEROUS ENVIRONMENTS. Do not use power tools in damp or wet locations or
expose them to rain. Keep your work area well lighted.
7. KEEP CHILDREN AND VISITORS AWAY. All children and visitors should be kept a safe dis-
tance away from your work area.
8. MAKE WORKSHOP CHILD-PROOF with padlocks, master switches, or by removing starter
keys.
9. DO NOT FORCE TOOL. Tools work better and more safely when they are allowed to work at
their own speed.
10. USE THE RIGHT TOOL. Do not use a tool or an attachment to do a job it wasn’t intended for.
11. WEAR PROPER APPAREL. Do not wear loose clothing, gloves, neckties, or jewelry that might
get caught in moving parts. Non-slip footwear is also recommended. Wear a hat or other protective head wear if your hair is long.
12. USE SAFETY GLASSES AND EAR PROTECTION. Also use a dust mask if the cutting oper-
ation creates dust or fumes.
13. SECURE YOUR WORK. Use clamps or a fixture to hold your work. It is safer than using your
hands and frees up both hands for operating the tool.
14. DO NOT OVERREACH. Keep proper footing and balance at all times.
15. MAINTAIN TOOLS IN TOP CONDITION. Keep tools sharp and clean for best and safest per-
formance. Follow instructions for lubricating and changing accessories.
16. DISCONNECT TOOLS FROM POWER before servicing and when changing accessories, such
as blades, bits and cutters.
17. USE RECOMMENDED ACCESSORIES. Consult the current catalog for recommended acces-
sories. The use of improper accessories may be hazardous.
18. AVOID ACCIDENTAL STARTING. Make sure the switch is in the “OFF” position before plug-
ging in the cord.
19. NEVER STAND OR LEAN ON TOOL. Serious injury could occur if the tool is tipped or if the
cutting tool is accidentally contacted.
20. CHECK DAMAGED PARTS. Before further use of the tool, any part or guard that is damaged
should be promptly repaired or replaced. Do not operate the machine until you are certain it is
in perfect running condition. Failure to follow this precaution could result in further mechanical
damage and operator injury.
21. DIRECTION OF FEED. Always feed your work against the direction of blade or cutter travel.
Workpieces fed in the same direction as the cutter travel could be forced out of your control.

V. PIECE INVENTORY
Take a quick inventory of the parts and put them aside for assembly later.
Since the majority of the Model G1126 is pre-assembled at the factory, there aren’t a lot of items to
inventory. You should have the following:
• Mill / Drill Unit
• Power Feed
• Fly Cutter
• Handwheels
• Adjustment Wrench
• Flycutter
• Drill Chuck Arbor
• Quill Feed Rods (3 pcs.)
•
1
/2" Drill Chuck and Key
22. NEVER LEAVE THE TOOL RUNNING UNATTENDED - TURN POWER OFF. Do not leave the
tool until it comes to a full stop.
23. DRUGS, ALCOHOL, MEDICATION. Do not operate the tool under the influence of drugs, alco-
hol, or any medication. Never operate machinery when overly fatigued.
IV. UNPACKING
The Model G1126 comes from the factory in a wooden crate. While it is still on its pallet, use a forklift (if available) to move the machine to its permanent location. Once in place, carefully remove the
crate surrounding the Model G1126 with a hammer or crowbar. Lift the Model G1126 with a sling
wrapped around the milling head to lift the machine off the pallet and onto your bench. Make sure
you tighten all the locks that restrict moving parts to avoid sudden shifts which could unbalance the
machine.
REMEMBER: Always wear ANSI-approved safety glasses when uncrating equipment.
If you find the machine is 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 situation, please call us.
Caution: The mill / drill weighs a hefty 660 pounds in its packaging. DO NOT attempt to move this
machine without proper lifting equipment.
