on the adjuster midway along the leadscrew. The longitudinal leadscrew adjuster can be tightened
with a long Allen wrench reached under the table. Once again, the setscrew in the tension adjuster
is located just above the longitudinal leadscrew. These adjusters may require you to fabricate
extensions for your hex wrenches. Make adjustments in small increments. Over-adjustment can add
unnecessary wear to both the leadscrews and the adjusters.
XI. EQUIPMENT MAINTENANCE
Your Model G1126 Gear Head Mill / Drill requires very little maintenance. A thorough cleaning, now
and again, will increase the machine’s durability and efficiency, by removing dust and grime that can
gum up moving parts. Sharp cutters are essential for top performance. If you find that the machine
cuts less efficiently than usual, inspect the cutters and repair or replace them as necessary. An
occasional application of a protective spray coating will keep the Model G1126’s table and other
bare metal parts from rusting and pitting.
REMEMBER: When performing maintenance or repairs on shop equipment, always disconnect the
machine from its power supply.
The Model G1126 features factory-sealed bearings. A sealed bearing requires no lubrication during
its lifetime. Should a bearing fail, your mill / drill will probably develop a noticeable rumble, which will
increase when the machine is put under load. If allowed to get worse, overheating of the journal con-
taining the bad bearing could occur. If the bad bearing is not replaced, it will eventually seize – pos-
sibly doing damage to other parts of the machine. Bearings are standard sizes and can be replaced
through Grizzly.
Points requiring periodic lubrication are:
1. The internal spline drive assembly. Insert top-quality non-hardening grease into the hole at the
top of the spindle pulley spline once every six months.
2. The main column. A light film of oil will smooth action and prevent rust and corrosion.
3. The quill. A light coating of oil will ensure smooth movement.
4. The quill return spring. Oil annually with a light lubricant (SAE 20). Apply with a brush or squirt
can.
5. The gear box. Replace lubricant annually with non-detergent SAE 30 oil.
6. The quill pinion. Lubricate every 90 days with non-hardening grease.
Note: Use care when performing maintenance. Never attempt maintenance procedures on the
machine while it’s running.
