GENERAL RULES FOR SAFE OPERATION

READ AND SAVE ALL INSTRUCTIONS FOR FUTURE USE. Before use, ensure operators reads and understand this manual. Read and 
understand labeling on machine and components. All operators must view the instruction video. Extra copies of the manual and video are avail-
able.

1. KNOW 

YOUR 

EQUIPMENT: Read this manual carefully to learn equipment applications and limitations, potential hazards associated with 

this type of equipment. Keep this manual with the equipment it is associated with. 

2. GROUND 

YOUR 

EQUIPMENT: See Grounding Page 7.

3.  AVOID DANGEROUS ENVIRONMENTS: Do not use in rain, damp or wet locations, or in the presence of explosive atmospheres (gas-

eous fumes, dust or fl ammable materials). Remove materials or debris that may be ignited by sparks.

4.  KEEP WORK AREA CLEAN AND WELL LIT: Cluttered, dark work areas invite accidents.
5.  DO NOT USE ON STEPS.
6. DRESS 

PROPERLY: Do not wear loose clothing. These may be caught in moving parts. When working wear gloves and insulated non-skid 

footwear. Keep hands and gloves away from moving parts.

7.  USE SAFETY EQUIPMENT: Proper eye protection should be worn at all times. Wear hearing protection during extended use and a dust 

mask for dusty operations. Hard hats, face shields, safety shoes, etc. should be worn when specifi ed or necessary.

8. KEEP 

BYSTANDERS 

AWAY: Children and other bystanders should be kept at a safe distance from the work area to avoid distracting the 

operator and contacting the equipment or extension cord. Operator should be aware of the proximity of bystanders. This appliance is not 
intended for use by persons (including children) with reduced physical, sensory or mental capabilities or lack of experience and knowledge. 
Equipment is not to be used by children.

9.  PROTECT OTHERS IN THE WORK AREA: Provide barriers or shields as needed to protect others from debris.
10. USE PROPER ACCESSORIES: Using accessories that are not recommended may be hazardous. Be sure accessories are properly 

installed and maintained. Do not delete a guard or other safety device when installing an accessory or attachment.

11.  CHECK FOR DAMAGED PARTS: Inspect guards and other parts before use. Check for misalignment, binding of moving parts, improper 

mounting, broken parts and other conditions that may affect operation. If abnormal noise or vibration occurs, turn off immediately and have 
the problem corrected before further use. Do not use damaged equipment. Tag damaged equipment “DO NOT USE” until repaired. Miss-
ing or damaged parts should be properly repaired or replaced immediately. For all repairs, use only identical National replacement parts.

12.  REMOVE ALL ADJUSTING KEYS AND WRENCHES: Make a habit of checking that the adjusting keys, wrenches, etc. are removed from 

the tool before turning it on.

13.  GUARD AGAINST ELECTRIC SHOCK: Prevent body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. 

When making cuts, always check the work area for hidden wires or pipes. Hold your equipment by insulated nonmetal grasping surfaces. 
Use a Ground Fault Circuit Interrupter (GFCI) to reduce shock hazards.

14. AVOID ACCIDENTAL STARTING: Be sure equipment is turned off before plugging in. Do not use equipment if the power switch does not 

turn the equipment on and off.

15.  DO NOT FORCE EQUIPMENT: Equipment will perform best at the rate for which it was designed. Excessive force only causes operator 

fatigue, increased wear and reduced control.

16.  KEEP HANDS AWAY FROM ALL CUTTING EDGES AND MOVING PARTS. 
17. WEAR gloves when changing accessories.
18.  DO NOT ABUSE CORD: Never unplug by pulling the cord from the outlet. Pull plug rather than cord to reduce the risk of damage. Keep 

the cord away from heat, oil, sharp objects, cutting edges and moving parts.

19.  DO NOT OVERREACH. MAINTAIN CONTROL: Keep proper footing and balance at all times. Maintain a fi rm grip.
20. STAY ALERT: Watch what you are doing, and use common sense. Do not use when you are tired, distracted or under the infl uence of 

drugs, alcohol or any medication causing decreased control.

21. STARTING MACHINE: On/Off switch must be in off position before connecting to power source.
22. UNPLUG EQUIPMENT: When not in use and before changing accessories or performing recommended maintenance, unplug machine.
23.  MAINTAIN EQUIPMENT CAREFULLY: Keep handles dry, clean and free from oil and grease. Keep cutting edges sharp and clean. Follow 

instructions for lubricating and changing accessories. Inspect tool cords and extension cords for damage. Replace damaged parts. Use
