Warning 

1.  Read and understand the entire owner’s manual before attempting assembly or operation. 

2.  Read and understand the warnings posted on the machine and in this manual. Failure to comply with all of 

these warnings may cause serious injury. 

3.  Replace the warning labels if they become obscured or removed. 

4.  This drill press is designed and intended for use by properly trained and experienced personnel only. If you 

are not familiar with the proper and safe operation of a drill press, do not use until proper training and 
knowledge have been obtained. 

5.  Do not use this drill press for other than its intended use. If used for other purposes, JET disclaims any real 

or implied warranty and holds itself harmless from any injury that may result from that use. 

6.  Do not use this machine in damp or wet locations, or expose it to rain. Keep work area well lighted. 

7.  Always wear approved safety glasses/face shields while using this drill press. (Everyday eyeglasses only 

have impact resistant lenses; they are not safety glasses.) 

8.  Before operating this drill press, remove tie, rings, watches and other jewelry, and roll sleeves up past the 

elbows. Remove all loose clothing and confine long hair. Non-slip footwear or anti-skid floor strips are 
recommended. Do 

not

 wear gloves. 

9.  Wear ear protectors (plugs or muffs) during extended periods of operation. 

10.  Some dust created by power sanding, sawing, grinding, drilling and other construction activities contains 

chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these 
chemicals are: 

 

Lead from lead based paint. 

 

Crystalline silica from bricks, cement and other masonry products. 

 

Arsenic and chromium from chemically treated lumber. 

Your risk of exposure 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 face or 
dust masks that are specifically designed to filter out microscopic particles. 

11.  Do not operate this machine while tired or under the influence of drugs, alcohol or any medication. 

12.  Make certain the switch is in the 

OFF

 position before connecting the machine to the power supply. 

13.  Clamp the workpiece or brace it against the column to prevent rotation. 

14.  Use the recommended speed for drill accessories and workpiece materials. 

15.  Make certain the machine is properly grounded. 

16.  Make all machine adjustments or maintenance with the machine unplugged from the power source. 

17.  Remove adjusting keys and wrenches. Form a habit of checking to see that keys and adjusting wrenches 

are removed from the machine before turning it on.  

18.  Keep safety guards in place at all times when the machine is in use. If removed for maintenance purposes, 

use extreme caution and replace the guards immediately after maintenance is complete. 

19.  Check damaged parts. Before further use of the machine, 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. 

20.  Provide for adequate space surrounding work area and non-glare, overhead lighting. 

21.  Keep the floor around the machine clean and free of scrap material, oil and grease. 

22.  Keep visitors a safe distance from the work area. 

Keep children away.

 

23.  Make your workshop child proof with padlocks, master switches or by removing starter keys.
