GENERAL SAFETY RULES

POWER TOOL USE AND CARE

1. REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure the power switch is in the OFF posi-
tion before connecting the plug to a power source or carrying the tool. 

2. CHECK POWER TOOL 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 condi-
tions that may affect its operation. Do not use the power tool if the switch does not turn ON/OFF. Any part that is 
damaged should be properly repaired or replaced before use.

3. USE THE RIGHT TOOL. Don’t force tool or attachment to do a job for which it was not designed. Use the 
correct power tool and accessories and follow the instructions for your application to prevent hazardous situations. 

4. DO NOT FORCE THE TOOL. It will do the job better and safer at the rate for which it was designed. 

5. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that keys and adjusting 
wrenches are removed from tool before turning it on.

6. KEEP GUARDS IN PLACE and in working order before operating the tool. 

7. NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Don’t leave tool until it comes 
to a complete stop.

8. 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.

9. 

USE RECOMMENDED ACCESSORIES. Consult the owner’s manual for recommended accessories. The use 

of improper accessories may cause risk of injury to persons.

10. 

NEVER STAND ON TOOL. 

Serious injury could occur if the tool is tipped or if the cutting tool is unintention-

ally contacted.

11. DIRECTION OF FEED.

 

Feed work into a blade or cutter against the direction of rotation of the blade or cut-

ter only.

WARNING: 

Dust generated from certain materials can be hazardous to your health. Always operate 

the tool in a well-ventilated area and wear dust mask. Use dust collection systems when processing 
wood and plastics. Dust extractors or dust bags must not be connected when processing metals.

POWER TOOL MAINTENANCE

1. Always disconnect the power cord plug from the electrical outlet when making adjustments, changing parts, or 
storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.

2. MAINTAIN TOOLS WITH CARE. Safely store power tools out of the reach of children. Keep tools sharp and 
clean for best and safest performance. Follow instructions for lubricating and changing accessories. 

3. Only have your power tool serviced by a qualified repair person using only identical replacement parts. Use of 
any other part can cause personal injury and damage to the tool.
