2.2. Loading Grease
2.2.1. Cartridge Loading Method
- Remove the gun head by rotating it in an anticlockwise direction.
- Pull the Plunger Rod Handle all the way back.
- Remove the plastic cap from the grease cartridge and insert the cartridge into the grease gun barrel.
- Remove the pull-tab seal from the cartridge.
- Screw the gun head tightly back onto the barrel.

2.2.2. Bulk Fill Method
- Remove the gun head by rotating it in an anticlockwise direction.
- Insert the open end of the barrel approximately 2 inches into the grease container.
- Slowly pull the plunger rod handle to draw in grease while pushing the grease gun deeper into the container.
- Gently shake the grease gun to allow grease to settle.
- Screw the gun head back onto the barrel.

2.2.3. Dispenser/Filler Pump Method
- Clean the grease gun's bulk loader valve to ensure it is free of grease.
- Connect the bulk loader cum Air Release Valve tightly onto the grease loader adapter.
- Begin operating the transfer pump, maintaining a firm grip on the grease gun.
- When the gun barrel is full, pumping will become noticeably harder.
- Stop pumping and disconnect the Bulk Loader cum Air Release valve.
2.3. Initial Priming and Air Release
After loading grease, it is crucial to prime the grease gun to remove any trapped air. Locate the air release valve (often integrated with the bulk loader valve) and open it slightly while operating the gun until grease flows smoothly. Close the valve once all air is purged.
2.4. Attaching the Hose and Coupler
Screw the 18-inch flexible hose extension onto the grease gun head. Attach the coupler securely to the other end of the hose. Ensure all connections are tight. For optimal performance and to prevent leaks, applying Teflon tape to threaded connections (gun head to body, hose to gun head, and hose to coupler) is recommended before assembly.
3. Operation
3.1. Adjusting Pressure and Volume
The Milton S-3101 features an adjustable stroke handle to switch between high-pressure and high-volume settings, adapting to different lubrication needs.
- High Pressure Setting (for cold weather or stubborn fittings): Lower the adjustment lever by pushing the bar downward. This setting provides maximum force for difficult lubrication points.
- High Volume Setting (for faster greasing): Lift the adjustment lever. This setting delivers more grease per stroke for quicker lubrication of accessible points.
Description: A diagram illustrating how to adjust the pistol handle of the Milton S-3101 Grease Gun. It shows two positions: one with the lever lowered for the "HI PRESSURE SETTING" and another with the lever lifted for the "HI VOLUME SETTING".
3.2. Applying Grease
- Ensure the grease gun is properly loaded and primed.
- Select the appropriate pressure/volume setting using the adjustable stroke handle.
- Connect the coupler firmly to the grease fitting (Zerk fitting) on the component to be lubricated.
- Operate the pistol grip handle to dispense grease. Continue pumping until fresh grease appears or resistance increases.
- To disconnect the coupler, apply a slight tilt and twist motion while pulling it off the fitting. If it remains stuck, slightly loosen the threaded connection between the coupler and the hose by a couple of turns to relieve pressure, then try to remove it. Remember to retighten the connection after removal.
4. Maintenance
4.1. Cleaning
Regularly wipe down the exterior of the grease gun to remove excess grease and dirt. Keep the coupler and hose clean to prevent contamination of grease fittings and ensure proper function.
4.2. Storage
Store the grease gun in a clean, dry place away from extreme temperatures. If storing for an extended period, ensure it is free of old grease and properly capped to prevent contamination and maintain its condition.
4.3. Inspection
Periodically inspect the hose, coupler, and seals for any signs of wear, cracks, or damage. Replace any worn components promptly to maintain optimal performance, prevent leaks, and ensure safe operation.
5. Troubleshooting
5.1. Grease Not Dispensing / Air Lock
If grease is not dispensing or the gun feels "air locked":
- Check Priming: Ensure the gun is properly primed. Open the air release valve slightly and pump the handle until grease flows, then close the valve.
- Cartridge Issues: Verify the grease cartridge is correctly installed and that the pull-tab seal has been completely removed.
- Plunger Position: Ensure the plunger rod is fully engaged and effectively pushing the grease forward. If the plunger is stuck or not moving, remove the bottom cap and gently push it into the correct position.
5.2. Coupler Stuck on Fitting
If the coupler is difficult to remove from a grease fitting:
- Tilt and Twist: Apply a slight tilt and twist motion while pulling the coupler off.
- Loosen Connection: If still stuck, slightly loosen the threaded connection between the coupler and the hose by a couple of turns. This can relieve pressure and allow easier removal. Remember to retighten the connection after removal.
5.3. Leaks
If grease is leaking from connections:
- Tighten Connections: Ensure all threaded connections (gun head, hose, coupler) are securely tightened.
- Teflon Tape: Consider applying Teflon tape to threaded connections during assembly to improve sealing and prevent leaks.
- Inspect Seals: Check O-rings and internal seals for wear or damage and replace them if necessary.
