4. Орнотуу
- Түтүктү даярдоо: Cut the tubing to the desired length using the included Mastercool 70027 Mini Tube Cutter. Ensure the cut is clean and square. Deburr the inside and outside edges of the tubing to remove any sharp edges or burrs that could interfere with flaring or cause leaks.
- Штамптарды жана адаптерлерди тандаңыз: Identify the correct die set and adapter for the desired flare type and tubing size. The magnetic adapter holder helps secure the chosen adapter.
- Түтүктөрдү киргизүү: Place the tubing into the appropriate die set opening. Ensure the tubing extends beyond the die face by the recommended amount for the specific flare type (refer to the operating instructions for each flare type).
- Secure the Die Set: Tighten the die set stabilizing arm to firmly hold the tubing in place.

5. Иштөө нускамалары
This section outlines the general flaring procedure and specific considerations for different flare types.
5.1 General Flaring Procedure
- After preparing the tubing and selecting the correct die/adapter (as per Setup), ensure the flaring cone is clean.
- Position the hydraulic ram assembly so the flaring cone aligns with the center of the tubing opening.
- Slowly pump the hydraulic handle. The flaring cone will advance into the tubing, forming the flare.
- Continue pumping until the hydraulic ram reaches its stop or the desired flare shape is achieved. Do not over-flare.
- To release the pressure, turn the release knob on the hydraulic ram counter-clockwise. The flaring cone will retract.
- Remove the flared tubing from the die set. Inspect the flare for uniformity and absence of cracks or imperfections.

5.2 Specific Flare Types
The Mastercool 72485-PRC can create the following flare types:
- 45° Double & Single Flares: Used primarily for brake lines and other automotive applications. Requires specific dies and adapters for single or double flare formation.
- Push Connect Flares: Essential for modern fuel and transmission lines. Use the designated push connect dies and adapters.
- GM Fuel Line Flares: Specific flare type for General Motors fuel lines. Utilize the GM fuel line dies and adapters.
- ISO Bubble Flares: Common in European automotive applications. Requires metric bubble flaring dies and adapters.
- GM Transmission Cooling Line Flares: Specialized flares for GM transmission cooling lines. Use the dedicated GM transmission cooling line dies and adapters.

6. Техникалык тейлөө
- Тазалоо: After each use, clean the flaring cone, dies, and adapters to remove any metal shavings or debris. Use a clean cloth.
- Майлоо: Periodically apply a light coat of machine oil to the moving parts of the hydraulic ram and the flaring cone to ensure smooth operation and prevent corrosion.
- Сактагыч: Always store the tool and all its components in the provided custom-molded case. This protects the precision dies and the hydraulic unit from damage and keeps all parts organized.
- Текшерүү: Regularly inspect the tool for any signs of wear, damage, or leaks in the hydraulic system. Do not use if damage is observed.
7. Кыйынчылыктарды
| Көйгөй | Мүмкүн себеп | Чечим |
|---|---|---|
| Flare is uneven or cracked. | Tubing not deburred; incorrect tubing extension; wrong die/adapter; tubing material too hard. | Ensure tubing is properly deburred. Verify correct tubing extension. Use appropriate die/adapter for tubing size and type. Consider annealing harder tubing materials if applicable. |
| Hydraulic ram does not advance or retract smoothly. | Low hydraulic fluid; air in system; lack of lubrication; debris. | Check hydraulic fluid level (if serviceable, refer to manufacturer for details). Bleed air from system (if applicable). Lubricate moving parts. Clean tool thoroughly. |
| Tubing slips during flaring. | Die set not tightened sufficiently; incorrect die size; oily tubing. | Ensure die set stabilizing arm is fully tightened. Use the correct die size for the tubing. Clean any oil or grease from the tubing and dies. |
