Thank you for buying our product. Dear Valued Customer: Thank you for buying our Pneumatic Airless Painting Equipment, Model <SP1636/28/(S)> LIGHT BEAR. Please read this manual carefully before starting to operate the equipment. Please pay particular attention to major specifications, warnings and precautions, including prohibited items. -
Page 3: For Your Safety
For Your Safety Please carefully read this manual and get acquainted with the equipment. Please observe the operating procedures in the manual. Failure to do so may result in personal injury and/or damage to property. This manual covers only minimum safety precautions, and it does not suggest or imply that no other precautions are required. - Page 4 WARNING Injection Hazard <<General Safety Precautions>> ● This is a high-pressure painting equipment and an extreme care should be exercised to prevent serious personal injury. This pump generates very high pressure to feed paint fluid to the airless spray gun. High-pressure spray or ruptured component pieces from point-blank range can inject fluid or fragments into your body, causing skin injury from which no small amount of toxic substances might enter into the body.
- Page 5 WARNING <<Nozzle Safety Precautions>> ● Don’t put your hand or fingers or anything over the spray nozzle. ● Be extra careful when cleaning or replacing the nozzle. If the nozzle gets clogged while spraying, immediately lock the trigger safety lock and relieve the fluid pressure in accordance with the “Pressure Relief Procedure,”...
- Page 6 WARNING Equipment Misuse Hazard <<General Safety Precautions>> ● Misuse, such as use of too much pressure, unauthorized component modification, improper paints or solvents, use of worn or broken part, may result in a serious accident like pump breakage, unexpected fluid injection, fluid splashed in the eyes or on the skin that possibly causes personal injury, or even fire or explosion.
- Page 7 WARNING ● When you fluid find leak, take no stopgap measures, such as covering the leak hole by hand or adhesive tape. Such measures will only increase potential hazards. ● When you find fluid leak, replace the hose with a new one or contact our authorized repair shop. ●...
- Page 8 WARNING Fire and Explosion Hazard <<Source of Fire>> As liquid flows through the pump and hose, static electricity is generated. If each component of the painting equipment is not properly grounded, sparks may occur due to static electricity. When there are vaporized solvent, sprayed paint particles, floating dust and other flammables in the atmosphere near the painting equipment, these sparks can cause fire or explosion, possibly causing serious injury to the operator and damage to the equipment.
- Page 9 WARNING □ Grounding Fluid Container When your fluid container is made of conductive metal, you can place it on the grounded floor or table. When it is made of something else, you cannot. □ Grounding Cleaning Solvent Can When the cleaning solvet is made of conductive metal, you can place it on the grounded floor or table.

If you find anything wrong, please get in touch with our agency near you or us directly at Asahi Sunac. (1) Upon unpacking you’ll find that the equipment, high-pressure hose, and spray gun are not assembled yet. -
Page 12: Operation
(6) Repeat Step (1) through (3), with paint fluid. (7) Adjust the air regulator to keep compressed air pressure at 0.2 to 0.5MPa. The fluid pressure of: SP1636 is 20 times the compressed air pressure, SP1628 is 30 times the compressed air pressure. Therefore, when the ratio is: 1:20, fluid pressure will be 4MPa ~ 10MPa, 1:30. - Page 13 ② Shutdown and Equipment Care (1) Check the equipment and hose for leak from joints. 1. Interruption or overnight shutdown with resumption due in 24 hours ① Leave the equipment filled with fluid. In this case, because air will be purged from the fluid passage keeping the fluid in the way as if it were stored in a paint can, the fluid in the equipment will be kept free from solidification.

Page 14: Color Change And Additive Addition Precautions
WARNING When you shutdown the equipment for interruption or overnight stoppage, always lock the spray gun trigger. If you fail to do so, it may be pulled accidentally, and personal injury may result. ③ Color change and additive addition precautions (1) When you change paint fluids, thoroughly flush the can with solvent so that no paint residue may be left unremoved. -
Page 15: Tear Down Inspection And Parts Replacement Procedure
Tear Down Inspection and Parts Replacement Procedure WARNING Before you take parts apart, always drain all paint fluid in the system and completely relieve the pump operating pressure and wrap air pressure down to zero. ① Air Motor When you apply grease to the cylinder interior or replace perishable parts, follow the procedure shown below. (See the exploded diagrams for the numbers referred to in the text.) Before you take parts apart, always drain all paint fluid in the system and shutdown compressed air supply. - Page 16 ② Material Cylinder (See page 21 for configurations and part names.) Shown below are the replacement procedures for the booster “V packing” at the upper end of the cylinder and the two suction “V packings” at the lower end of piston rod. Packing can be adjusted by retightening the packing retainer (2).

Page 17: Troubleshooting
Troubleshooting Symptom Cause Remedy 1. No fluid pressure ① Air regulator valve not opened. ① Fully open (turn clockwise). ② Defective pressure gauge ② Replace it with a new one. ③ Poor cleaning: Pump valve stuck due ③ Flush thoroughly with thinner. to hardened paint If hardened paint still remains after that, disassemble pump and clean. -
Page 18: Performance Tips
NOTICE V Packing Replacement Precautions (1) Install V packings in the correct direction with the convex side pointing in the right direction. (2) Cylinder⑭ clearance should be such that it can be pushed in by hand. When it’s too tight, do not use plain washers⑪ at all or use only one washer. If the clearance is too tight, cylinder stroke may get sticky. -
