Safety Instructions for Machinery

7.ONLY ALLOW TRAINED AND PROP- ERLY SUPERVISED PERSONNEL TO OPERATE MACHINERY. Make sure oper- ation instructions are safe and clearly understood.

8.KEEP CHILDREN AND VISITORS AWAY. Keep all children and visitors a safe dis- tance from the work area.

9.MAKE WORKSHOP CHILD PROOF. Use padlocks, master switches, and remove start switch keys.

10.NEVER LEAVE WHEN MACHINE IS RUNNING. Turn power OFF and allow all moving parts to come to a complete stop before leaving machine unattended.

11.DO NOT USE IN DANGEROUS ENVIRONMENTS. DO NOT use machin- ery in damp, wet locations, or where any flammable or noxious fumes may exist.

12.KEEP WORK AREA CLEAN AND WELL LIT. Clutter and dark shadows may cause accidents.

13.USE A GROUNDED EXTENSION CORD RATED FOR THE MACHINE AMPERAGE. Undersized cords overheat and lose power. Replace extension cords if they become damaged. DO NOT use extension cords for 220V machinery.

14.ALWAYS DISCONNECT FROM POWER SOURCE BEFORE SERVICING MACHINERY. Make sure switch is in OFF position before reconnecting.

15.MAINTAIN MACHINERY WITH CARE. Keep blades sharp and clean for best and safest performance. Follow instructions for lubricating and changing accessories.

16.MAKE SURE GUARDS ARE IN PLACE AND WORK CORRECTLY BEFORE USING MACHINERY.

17.REMOVE ADJUSTING KEYS AND WRENCHES. Make a habit of checking for keys and adjusting wrenches before turn- ing machinery ON.

18.CHECK FOR DAMAGED PARTS BEFORE USING MACHINERY. Check for binding and alignment of parts, broken parts, part mounting, loose bolts, and any other conditions that may affect machine operation. Repair or replace damaged parts.

19.USE RECOMMENDED ACCESSORIES. Refer to the instruction manual for recom- mended accessories. The use of improper accessories may cause risk of injury.

20.DO NOT FORCE MACHINERY. Work at the speed for which the machine or acces- sory was designed.

21.SECURE WORKPIECE. Use clamps or a vise to hold the workpiece when practi- cal. A secured workpiece protects your hands and frees both hands to operate the machine.

22.DO NOT OVERREACH. Keep proper foot- ing and balance at all times.

23.MANY MACHINES WILL EJECT WORKPIECE TOWARD OPERATOR. Know and avoid conditions that cause the workpiece to "kickback."

24.ALWAYS LOCK MOBILE BASES (IF USED) BEFORE OPERATING MACHINERY.

25.BE AWARE THAT CERTAIN WOODS MAY CAUSE AN ALLERGIC REACTION in people and animals, especially when exposed to fine dust. Make sure you know what type of wood dust you will be exposed to and always wear an approved respirator.

G7947, G7948 specifications

The Grizzly G7948 and G7947 are powerful, professional-grade milling machines designed for precision metalworking. These models cater to the needs of machinists and hobbyists alike, combining innovation with robust features ideal for various milling tasks.

The Grizzly G7948 is a vertical mill with a large working table, allowing users to handle bigger workpieces efficiently. It features a 2 HP motor, providing a spindle speed range from 50 to 3,000 RPM, enabling operators to tackle a wide range of materials and applications. The G7948’s dovetail column ensures stability and rigidity, minimizing vibrations during operation, which is crucial for achieving precision in milling tasks.

On the other hand, the Grizzly G7947 is a versatile combination of a lathe and a mill, perfect for those looking to maximize functionality in a smaller workspace. It also boasts a robust 1 HP motor, allowing for smooth operation with adjustable spindle speeds, enhancing its versatility. The G7947 is particularly user-friendly, featuring a quick-change tool post that facilitates faster tool swapping and changeovers, which is a significant advantage when working on multiple projects.

Both models come equipped with advanced features such as a digital readout (DRO) system that aids in precision measurements. The DRO provides real-time feedback on the machine's positioning, helping eliminate guesswork and ensuring accuracy. Additionally, the machines' power feed for the table enhances efficiency, making it easier for users to execute repetitive tasks without the strain of manual cranking.

Another notable characteristic of the Grizzly G7948 and G7947 is their user-friendly controls, designed with ergonomics in mind. The intuitive layout ensures that operators can easily navigate through the machine’s settings, allowing for quicker setup times and smoother workflow.
