Safety is a combination of common sense, staying alert 

and knowing how to use your power tool.

understood the following.
1. 

READ and become familiar with the entire 

      Operator’s Manual. 

LEARN the tool’s application,   

limitations and possible hazards.

2. 

KEEP GUARDS IN PLACE and in working order.

3. 

REMOVE ADJUSTING KEYS AND WRENCHES. 

Form the habit of checking to see that keys and 

adjusting wrenches are removed from the tool 

before turning ON.

4. 

KEEP WORK AREA CLEAN. Cluttered areas and 

benches invite accidents.

5. 

DO NOT USE IN DANGEROUS ENVIRONMENT.  

Do not use power tools in damp or wet locations, or 

expose them to rain. Keep work area well lighted.

6. 

KEEP CHILDREN AWAY. All visitors should be 

kept a safe distance from work area.

7. 

MAKE WORKSHOP CHILD PROOF with padlocks, 

master switches, or by removing starter keys.

8. 

DO NOT FORCE THE TOOL. It will do the job better 

and safer at the rate for which it was designed.

9. 

USE THE RIGHT TOOL. Do not force tool or 

attachment to do a job for which it was not designed. 

10. 

USE PROPER EXTENSION CORD. Make sure 

your extension cord is in good condition. When 

using an extension cord, be sure to use one heavy 

enough to carry the current your product will draw. 

An undersized cord will result in a drop in line 

voltage and in loss of power that will cause the tool 

to overheat. The table on page 5 shows the correct 

size to use depending on cord length and nameplate 

ampere rating. If in doubt, use the next heavier 

gauge. The smaller the gauge number, the heavier 

the cord.

11. 

WEAR PROPER APPAREL. Do not wear loose 

clothing, gloves, neckties, rings, bracelets or other 

jewelry that may get caught in moving parts. Non-

slip footwear is recommended. Wear protective hair 

covering to contain long hair.

12. 

ALWAYS WEAR EYE PROTECTION. Any Scroll 

Saw can throw foreign objects into the eyes that 

could cause permanent eye damage. ALWAYS 

wear Safety Goggles (not glasses) that comply with 

ANSI Safety standard Z87.1 Everyday eyeglasses 

have only impact–resistance lenses. They ARE 

NOT safety glasses. 

NOTE: Glasses or goggles not 

in compliance with ANSI Z87.1 could cause serious 

injury.

13. 

WEAR A FACE MASK OR DUST MASK. Sawing 

operation produces dust.

14. 

SECURE WORK. Use clamps or a vise to hold work 

when practical. It’s safer than using your hand and it 

frees both hands to operate tool.

15. 

DISCONNECT TOOLS before servicing; when 

changing accessories such as blades, bits, cutters, 

and the like.

Consult the Operator’s Manual for recommended

NEVER STAND ON TOOL. Serious injury could 

occur if the tool is tipped or if the cutting tool is 

unintentionally contacted.

19. 

CHECK FOR 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 

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.

cutter against the direction of rotation of the blade or 

cutter only.

DO NOT OPERATE the tool if you are under the 

influence of any drugs, alcohol or medication that 

could affect your ability to use the tool properly.

25. 

DUST generated from certain materials can be
