Pneumatic grease gun for 400g cartridges, rigid or flexible up to 10bar - Professional lubrication without effort
Are you looking for a reliable, efficient and durable solution for lubricating your machinery and equipment? The 400g Cartridge Pneumatic Grease Gun (model G02907) is a premium pneumatic tool designed for professional use in demanding working environments. This powerful pneumatic grease gun enables fast, precise and uniform application of lubricant under high pressure up to 10 bar, which significantly reduces maintenance time and extends the life of your equipment.
Thanks to the ability to use both standard 400g cartridges and bulk grease, this grease gun offers exceptional flexibility. You get both a rigid and flexible hose in the kit, allowing you to easily access hard-to-reach lubrication points (nipples). Forget about manual pumping and hand fatigue - the pneumatic drive does the hard work for you.
Why choose the G02907 pneumatic lubricator?
Regular and proper lubrication is essential to prevent friction, overheating and premature wear of mechanical parts. The 400g pneumatic cartridge grease gun ensures a constant flow of grease without air bubbles, as it is equipped with a specialized vent and relief safety valve. This ensures safe operation and optimal utilization of each cartridge.

Instructions for safe and effective use
To achieve the best results and a long tool life, we recommend the following steps:

Before first use or changing the cartridge, make sure the lubricator is assembled correctly.
When using bulk grease, be careful not to introduce impurities into the reservoir that could clog the nozzle.
After inserting the cartridge, use the bleed valve to expel any trapped air.
Connect the lubricator to a stable source of compressed air with a working pressure between 2 and 10 bar.
After finishing work, clean the tool and store it in a dry place.

Frequently Asked Questions (FAQ)
1. Can I use this lubricator with a regular compressor?
Yes, the pneumatic grease gun operates on compressed air and can be easily connected to most standard workshop compressors via a standard 1/4" connection. The tool's operating pressure is between 2 and 10 bar, which corresponds to the capabilities of conventional compressors.
2. What is the difference between using a rigid and flexible hose?
A rigid metal tube is ideal for stable and precise application of grease to easily accessible places where you can apply strong pressure to the grease gun. A flexible tube is indispensable for reaching hard-to-reach, hidden or narrow places at angles where a rigid tube would not be able to reach the lubrication point.
3. How do I fill the grease gun with bulk grease?
The grease gun offers dual filling options. In addition to using standard 400g cartridges, you can unscrew the reservoir and fill it manually or with a filling pump with bulk grease directly from a larger container. After filling, use the bleed valve to remove air.

Instructions for using the product:
• Before use, check that the pneumatic lubricator is properly connected to the compressed air source and that the pressure is set according to the manufacturer's instructions.
• Remove the cap from the grease cartridge and insert it into the grease gun according to the manufacturer's instructions.
• Check that the seal is correctly installed and that the lubricator is ready for use.
• By pressing the trigger of the pneumatic grease gun, begin to evenly apply lubricant to the desired parts of the equipment or machine.
• After finishing work, clean the grease gun and store it in a dry place, away from direct sunlight.

Useful tips for work:
• Before use, check the compatibility of the lubricant with the pneumatic lubricator and make sure that the cartridge is installed correctly.
• When using flexible grease, ensure that the pneumatic lubricator is set correctly for the desired pressure to ensure optimal application.
• Regularly maintain the pneumatic lubricator to prevent the build-up of lubricant residue and ensure smooth operation.
• When using solid lubricant, pay attention to proper dosage and even application to prevent over-lubrication or leakage.
• Clean and dry pneumatic lubricators before storing them to prevent clogging and malfunctions the next time they are used.

Warnings:
• Do not exceed the maximum operating pressure of 10 bar.
• Always disconnect the compressed air supply and relieve pressure before changing hoses, attachments or cartridges.
• Never direct compressed air towards yourself or other people.
• When lubricating, be aware of the risk of grease being ejected under high pressure, as grease under pressure can cause serious damage.
• Do not use a damaged grease gun, hoses, fittings or attachments.
• Do not interfere with or block the safety or relief valve.
• Use only the appropriate 400-g cartridges or grease compatible with the grease gun.
