Fini FH3OL195N - User Manual

This document is the operator's manual for the Fini Advanced FH3OL195N 3 Gallon Portable Air Compressor. It provides comprehensive information on the compressor's features, assembly, operation, maintenance, and troubleshooting, along with important safety rules and warranty details.

Function Description

The Fini Advanced FH3OL195N is a portable air compressor designed for consumer use. Its primary function is to compress air and store it in a tank for various pneumatic applications. It is suitable for operating air-powered tools requiring less than 2.5 SCFM @ 90 PSI, such as pneumatic nail guns, inflating tires, and cleaning/blowing with pressurized air. The compressor is equipped with an oil-free universal motor, meaning it does not require oil lubrication, simplifying maintenance.

The compressor operates by drawing in air through an air intake filter. A reciprocating piston in the pump compresses the air, which is then forced through a check valve into the air tank. A pressure switch automatically controls the on/off cycling of the compressor, stopping it when the cut-off pressure is reached and restarting it when the air pressure drops below the cut-in pressure. A safety valve is incorporated to prevent system failures by relieving pressure if it exceeds a predetermined limit. The unit also features a thermal overload switch that automatically shuts off the compressor if the electric motor overheats, protecting it from damage.

Important Technical Specifications

Running Horsepower: 1.0 HP
Air Tank Capacity: 3 gallons
Air Pressure (Max): 150 PSI
Air Delivery: 2.5 SCFM @ 90 PSI
Duty Cycle: S3/50% (5 minutes ON and 5 minutes OFF) – This indicates intermittent operation to prevent motor overheating. If run time exceeds this, the application requires more air than the compressor can deliver.
Lubrication: Oil-Free
Gauges: 2.0 in. diameter (Tank Pressure Gauge and Regulator Pressure Gauge)
Input: 120 V, 60 Hz, AC only, 9 Amps
Net Weight (compressor only): 24.3 lbs.
Extension Cord Requirements: For lengths up to 50 feet, a minimum 14 A.W.G. wire gauge is recommended. For lengths exceeding 100 feet, a heavier gauge is advised.
Breathing Air Quality: This compressor/pump is not equipped to supply breathing quality air and should not be used for this purpose without additional filtering and purification equipment.

Usage Features

The FH3OL195N is designed for ease of operation with several user-friendly features:

Manual On/Off Switch: This switch allows the user to manually turn the compressor on or off. When in the ON position, the pressure switch takes over automatic cycling.
Pressure Regulator Knob: This knob allows the user to adjust the outgoing air pressure delivered to the tool. Turning it clockwise increases pressure, while counterclockwise reduces it.
Regulator Pressure Gauge: Displays the current line pressure being delivered to the tool.
Tank Pressure Gauge: Indicates the pressure of the air stored in the tank.
Quick Coupler: Provides a convenient connection point for air hoses and tools.
Drain Valve: Located at the bottom of the tank, this valve is used to remove moisture (condensation) from the air tank, which is crucial for preventing corrosion.
Air Intake Filter: Cleans incoming air to the pump, ensuring a clean, cool, and dry air supply.
Portable Design: The compressor's compact size and relatively light weight (24.3 lbs.) make it easy to transport and store. It includes a handle for carrying.
Safety Features:
- Safety Valve: Automatically releases pressure if it exceeds the preset maximum, preventing system failures. Users are instructed to check its proper function daily by pulling the ring.
- Thermal Overload Protector: Automatically shuts off the motor if it overheats, preventing damage. The motor resets automatically once it cools down.
- Grounding Instructions: The compressor is equipped with a 3-prong grounding plug and must be connected to a properly grounded outlet to reduce the risk of electric shock.

Maintenance Features

Regular maintenance is essential for the compressor's longevity and safe operation. The manual outlines key maintenance tasks:

Daily Tank Draining: The drain valve should be opened daily (or every hour in humid conditions) to remove condensation from the air tank. This prevents corrosion and ensures cleaner air delivery.
Safety Valve Check: The safety valve should be checked daily before use to ensure it is working properly. This involves pulling the ring to release air and verifying that it stops escaping once the ring is released.
Tank Inspection: The air tank should be inspected yearly for rust, pinholes, or other imperfections that could compromise its safety. Welding or drilling holes in the tank is strictly prohibited.
Cleaning: The exterior of the air compressor should be kept dry, clean, and free from oil and grease. Clean cloths should be used, and strong solvents like brake fluids, gasoline, or petroleum-based products should be avoided as they can damage plastic parts.
Oil-Free Lubrication: The universal motor features permanently lubricated bearings, eliminating the need for additional lubrication throughout the unit's normal operating life.
Hose Inspection: Air hoses should be checked for weak or worn conditions before each use, and connections should be secure. Damaged hoses should be replaced or repaired by an authorized service center.
Air Filter Maintenance: The air intake filter should be kept clean and free from obstructions to ensure the pump receives a clean air supply.
Storage: After use, the compressor should be unplugged, the tank drained of air and condensation, and the unit stored in a cool, dry place. The air hose should also be disconnected and hung with open ends down to allow any moisture to drain.

The manual emphasizes that all service and maintenance, especially repairs, should be performed by qualified repair personnel using identical replacement parts to avoid injury and maintain warranty validity.
