SAFETY WARNING & CAUTIONS

WARNING: When using pneumatic equipment, basic safety precautions should always be followed to reduce the risk of personal injury and hazards due to over pressurization. READ ALL

INSTRUCTIONS BEFORE USING THIS TOOL!

1. KEEP WORK AREA CLEAN. Cluttered areas invite injuries.

2. OBSERVE WORK AREA CONDITIONS. Do not use tools in damp, wet, or poorly lit locations.

Don’t expose to rain. Keep work area well lit. Do not use electrically powered air compressors in the presence of flammable gases or liquids.

3. KEEP CHILDREN AWAY. Children must never be allowed in the work area. Do not let them

handle machines, tools, or hoses.

4. STORE IDLE EQUIPMENT. When not in use, tools must be locked up in a dry location to

inhibit rust. Always lock up tools and keep out of reach of children.

5. DO NOT FORCE THE TOOL. It will do the job better and more safely at the rate for which

it was intended. Do not use inappropriate attachments in an attempt to exceed the tool’s capacities.

6. USE THE RIGHT TOOL FOR THE JOB. Do not attempt to force a small tool or attachment

to do the work of a larger industrial tool. Do not use a tool for a purpose for which it was not intended.

7. DRESS PROPERLY. Do not wear loose clothing or jewelry as they can be caught in moving

parts. Non-skid footwear is recommended. Wear restrictive hair covering to contain long hair. Always wear the hood (included), a dust mask, and heavy duty canvas gloves.

8. USE EYE AND EAR PROTECTION. Always wear ANSI approved chemical splash

goggles when working with chemicals. Always wear ANSI approved impact safety goggles at other times. Wear a full face shield if you are producing metal filings or wood chips. Wear and ANSI approved dust mask or respirator when working around metal, wood, and chemical dusts and mists.

9. DO NOT ABUSE THE POWER CORD. Do not yank compressor’s cord to disconnect it

from the receptacle. Do not carry tools by the cord.

10. DO NOT OVERREACH. Keep proper footing and balance at all times. Do not reach over

or across running machines.

11. MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and safer

performance. Follow instructions for lubricating and changing accessories. Inspect compressor’s cord periodically and, if damaged, have them repaired by an authorized technician. Inspect all hoses for leaks prior to use. The handles must be kept clean, dry, and free from oil and grease at all times.

12. REMOVE ADJUSTING KEYS AND WRENCHES. Make it a habit to check that keys and

adjusting wrenches are removed from the tool or machine work surface before plugging it in.

13. AVOID UNINTENTIONAL STARTING. Make sure the nozzle valve is in the off position

when not in use, and before plugging in air compressor.

14. STAY ALERT. Watch what you are doing, use common sense. Do not operate any tool

when you are tired.

15. CHECK DAMAGED PARTS. Before using any tool, any part that appears damaged

should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment and binding of moving parts; any broken parts or mounting fixtures; and any other condition that may affect proper operation. Any part that is damaged should be properly repaired or replaced by a qualified technician. Do not use the tool if any switch does not turn on and off properly.

16. REPLACEMENT PARTS AND ACCESSORIES. When servicing, use only identical

replacement parts. Use of any other parts will void the warranty. Only use accessories intended for use with this tool. Approved accessories are available from Harbor Freight Tools.

17. DO NOT OPERATE TOOL IF UNDER THE INFLUENCE OF ALCOHOL OR DRUGS.

Read warning labels on prescriptions to determine if your judgment or reflexes are impaired while taking drugs. If there is any doubt, do not operate the tool.

18. DRAIN COMPRESSOR EVERY DAY. Do not allow moisture to build up inside the

compressor. Do not allow compressor to sit pressurized for longer than one hour.

19. MAKE SURE ALL EQUIPMENT IS RATED TO THE APPROPRIATE CAPACITY. Make

sure that regulator is set at no higher than 125 PSI.

20. PERIODICALLY CHECK THE ABRASIVE MEDIUM DELIVERY EQUIPMENT. All

equipment that comes in contact with the abrasive medium after it leaves the pressure tank is subjected to the sandblasting action so will wear out more quickly than other components.

21. RELEASE THE AIR PRESSURE OF THE TANK BEFORE OPENING. Open the air

supply valve and the nozzle to release pressure. Make sure pressure gauge reads “0” before opening.

22. MAINTAIN CORRECT AIR PRESSURE WHENEVER WORKING. Do not allow pressure

to exceed 125 PSI. If the safety valve does not release excess air pressure, stop all work and use the air compressor to release pressure in the tank. Do not attempt any repairs to the Sandblaster until its gauge reads “0”.
