Opsætning
Proper setup is crucial for the efficient operation of your grease gun.
Loading a Grease Cartridge:
- Unscrew the barrel from the head assembly.
- Pull the plunger rod all the way back and lock it into the slot on the head assembly.
- Remove the plastic cap from one end of a new grease cartridge and insert the open end into the barrel.
- Remove the pull-tab seal from the other end of the cartridge.
- Screw the barrel back onto the head assembly until hand-tight.
- Release the plunger rod from its locked position and push it forward slightly to ensure it engages with the cartridge follower.
- Prime the gun by pumping the lever several times until grease begins to flow from the nozzle. If air pockets persist, loosen the head assembly 1.5 turns and pump until grease flows, then retighten.

Betjeningsvejledning
Follow these steps for effective lubrication:
- Ensure the grease gun is properly loaded and primed.
- Clean the zerk fitting on the component to be lubricated to prevent contamination.
- Press the coupler firmly onto the zerk fitting until it snaps into place.
- Operate the lever handle with steady, full strokes until fresh grease appears or resistance is felt. Refer to the equipment manufacturer's recommendations for specific lubrication intervals and quantities.
- To remove the coupler, tilt it slightly and pull it straight off the zerk fitting.
- Wipe any excess grease from the zerk fitting and the grease gun nozzle.

Opretholdelse
Regular maintenance ensures the longevity and optimal performance of your Lincoln 1142 grease gun.
- Rensning: After each use, wipe down the exterior of the grease gun to remove any excess grease or dirt.
- Check Valve Cleaning: The accessible check valve allows for easy cleaning. If hardened or contaminated grease is suspected, disassemble the check valve (as shown in the setup image) and clean its components. Lincoln recommends cleaning at least twice a year, which takes less than five minutes.
- Koblingsinspektion: Periodically inspect the coupler for wear or damage. Replace if it no longer forms a tight seal on zerk fittings.
- Opbevaring: Store the grease gun in a clean, dry environment to prevent corrosion and contamination.

Fejlfinding
Almindelige problemer og deres løsninger:
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Grease gun does not pump grease (no prime/loss of prime) | Air pockets in the system; grease too cold or thick; improper cartridge loading. | Follow priming instructions (loosen head 1.5 turns, pump, retighten). Verify grease is NLGI 2 or less. Warm grease if operating in cold temperatures. Ensure cartridge is loaded correctly and plunger rod is engaged. |
| Grease gun is leaking | Worn coupler; old/bad grease causing oil separation; loose connections. | Check what is leaking and where. Replace worn coupler. Ensure all connections are tight. If oil is leaking, it may indicate old or bad grease; replace grease. |
| Grease around the spring (inside the barrel) | Improper positioning of the follower lip seal (older models); worn follower. | Ensure the follower lip seal is properly positioned to prevent grease bypass. If the follower is worn, it may need replacement. |
