Descrizione
Friction is the quiet tax every machine pays.
Bearings, pins, and pivot points work hardest exactly when they are least lubricated. The Pressure Scribe delivers grease at a sustained 10,000 PSI, punching through packed fittings and reaching the journals that hand pumps cannot touch. Its brushless motor runs cool, fast, and without the carbon dust that strangles cheap electric guns, so the tool outworks and outlives the fleet it services.
Built for the Makita 18V battery platform, it drops straight into the battery ecosystem most workshops already own instead of demanding a proprietary power system. The high-pressure steel head, precision-cast gear housing, and bleed valve convert battery power into controlled, repeatable grease delivery. Exhaust old grease, purge air, and refill from cartridges or a bulk barrel without stopping the job.
Machinery does not fail from wear. It fails from neglect, measured in ungreased fittings.
Key Features
- 10,000 PSI (69 MPa) maximum pressure drives grease into seized and high-torque fittings
- Brushless motor delivers longer runtime, higher torque, and no carbon-brush wear
- Compatible with Makita 18V slide-on batteries, sharing power with existing shop tools
- Heavy-duty steel pump head and die-cast gear case built for daily workshop abuse
- Air-bleed valve expels trapped air for instant priming after cartridge changes
- High-pressure rigid hose with premium coupler locks onto standard grease nipples
- Works with both 400g cartridges and bulk-filled reservoir for workshop efficiency

Application Scenarios
The Pressure Scribe is the daily tool of tractor and truck fleets, agricultural workshops, construction yards, and any facility that keeps heavy pivots alive. Operators use it to grease loader pins and fifth wheels at 10,000 PSI without climbing under a second time, while workshop teams service excavator bushings, conveyor bearings, and trailer axles between shifts. Because it rides the Makita 18V platform, the same battery that powers a drill keeps the grease gun fed all day, and the bulk-fill option turns a 50-pound barrel into the cost-effective heart of a preventive maintenance routine.
Frequently Asked Questions
Q: Will this gun work with my Makita batteries?
Yes, the tool is built for Makita 18V slide-on batteries. Any Makita 18V battery, including the popular 3.0Ah and 5.0Ah packs, powers the gun. The battery clicks in firmly and the trigger lock prevents accidental discharge.
Q: How do I prime the gun after changing a cartridge?
Install the cartridge, then open the air-bleed valve and run the motor briefly until grease flows cleanly from the vent. Close the valve and the gun is ready. The 10,000 PSI pump self-primes quickly and rarely needs more than a few seconds.
Q: Can it handle bulk grease instead of cartridges?
Yes. Remove the cartridge tube and insert the suction hose into a bulk grease barrel. The piston draws grease directly from the barrel, which is the most economical way to service a large fleet.
Q: What pressure can this gun actually reach?
The pump is rated to a maximum of 10,000 PSI (69 MPa). Actual delivery pressure depends on the fitting and the grease grade, but standard chassis nipples seal easily without leaking at this pressure.
Q: Is the hose included?
Yes, a high-pressure rigid hose with a premium locking coupler is included and attaches to the steel head. The coupler grips standard grease nipples securely and releases with a simple pull.
Q: Is this gun suitable for automotive DIY use?
Absolutely. It is equally at home on passenger cars, where it greases ball joints, tie rod ends, and U-joints with less effort than any hand gun, making suspension service a ten-minute task.
Q: How much grease does it deliver per stroke cycle?
The pump delivers a steady, controlled flow rated for high-pressure lubrication work, moving grease quickly through long lines and into tight fittings. The brushless motor maintains consistent delivery pressure whether the cartridge is full or nearly empty, so the last fitting gets the same charge as the first.
Q: What maintenance does the grease gun need?
Very little. Keep the grease inlet clean, wipe the coupler after every session, and store the gun with the trigger locked. The brushless motor has no carbon brushes to replace, and the steel pump head is designed for years of service with periodic inspection of the coupler seal.
Q: Does it come with a warranty?
Yes, the tool is covered by a manufacturer warranty against defects in materials and workmanship. Register the serial number after purchase for full coverage details and keep the receipt with your workshop documentation.
