RULES FOR SAFE OPERATION
READ AND SAVE ALL INSTRUCTIONS FOR FUTURE USE. Before use, be sure everyone
operating this equipment reads and understands this manual as well as any labels packaged with or
attached to the machine. Extra copies of the manual are available upon request.
1. KNOW YOUR EQUIPMENT: Read this manual and view instruction video carefully to learn
equipment applications and limitations as well as potential hazards associated with this type of
equipment.
2. GROUND YOUR TOOL: See Grounding page 6.
3. AVOID DANGEROUS ENVIRONMENTS: Do not use in rain, damp or wet locations, or in the
presence of explosive atmospheres (gaseous fumes, dust or flammable 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 outdoors, wear rubber gloves and insulated non-skid footwear. Keep hands and gloves away
from moving parts.
7. USE SAFETY EQUIPMENT: Everyone in the work area should wear safety goggles or glasses
complying with current safety standards. Wear hearing protection during extended use and a dust
mask for dusty operations. Hard hats, face shields, safety shoes, etc. should be worn when specified
or necessary.
8. KEEP BYSTANDERS AWAY: Children and bystanders should be kept at a safe distance from the
work area to avoid distracting the operator and contacting the tool or extension cord. Operator should
be aware of who is around them and their proximity.
9. PROTECT OTHERS IN THE WORK AREA: Provide barriers or shields as needed to protect others
from debris and machine operation.
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 any other conditions that
may affect operation. If abnormal noise or vibration occurs, turn the tool off immediately and have the
problem corrected before further use. Do not use damaged equipment. Tag damaged tools “DO NOT
USE” until repaired. A guard or other damaged parts should be properly repaired or replaced. For all
repairs, insist on 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 scoring or making cuts, always check the work area for
hidden wires or pipes. Hold machine 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 it in. Do not use
if the power switch does not turn the machine on and off.

RULES FOR SAFE OPERATION
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 MOVING PARTS.
17. WEAR GLOVES WHEN CHANGING ACCESSORIES.
18. DO NOT ABUSE CORD: Never unplug by yanking 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 firm grip.
20. STAY ALERT: Watch what you are doing, and use common sense. Do not use when you are tired,
distracted or under the influence 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 it is not in use, unplug tool before changing blades, accessories or
performing recommended maintenance or when not in use.
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.
Periodically inspect tool cords and extension cords for damage. Have damaged parts repaired
or replaced.
24. STORE IDLE EQUIPMENT: When not in use, store in a dry, secured place. Keep away
from children.
25. MAINTAIN LABELS AND NAMEPLATES: These carry important information. If unreadable or
missing, contact National for a free replacement.
26. MACHINE IS HEAVY, DO NOT DROP: Counter weights are heavy. Take caution when removing
or reassembling. Take caution when moving or transporting.
WARNING: Exposure to dust may cause respiratory ailments. Use approved NIOSH or OSHA
respirators, safety glasses or face shields, gloves and protective clothing. Provide adequate ventilation
to eliminate dust, or to maintain dust level below the Threshold Limit Value for nuisance dust as
classified by OSHA.

SAFETY SITE ASSESSMENT
Before starting blasting operations as site assessment should be performed. During the site assessment
verify the following:
1. Work area is clean, dry, free of debris, and machine will clear all obstructions. NEVER BLAST AWET
FLOOR AND NEVER ALLOW PERSONNEL, ELECTRICAL CORDS, OR CONNECTIONS TO COME INTO CONTACT WITH
MOISTURE. NEVER BLAST OVER NUTS, BOLTS, SCREWS, NAILS OR OTHER DEBRIS AS THIS MAY RESULT IN SIGNIFICANT
DAMAGE TO THE MACHINE AND SERIOUS INJURY TO THE OPERATOR.
2. Operator any any other personnel in the work area are wearing safety glasses with side shield, dust
masks, ear plugs, hard hats, steel toed work boots, long sleeved shirts and gloves.
3. All glass and equipment are protected from steel shot. This can be done by loosely hanging a sheet of
visquene or other protective material in front of the window or equipment in a curtain like fashion. THE
IMPORTANCE OF PROTECTING EQUIPMENT AND MACHINERY FROM STEEL SHOT CANNOT BE OVER EMPHASIZED.
4. Plug or cover all floor drains to prevent steel shot from falling into the drains.
5. Do not allow pedestrians or unprotected personnel into the work area. In the event pedestrians or
other unprotected personnel enter the work area, cease blasting operations.
