I’ve spent way too many hours wrestling with manual grease guns that leave my hands cramping and the job half done. That’s exactly why I tested the Lincoln 1162 Pneumatic Grease Gun with 30″ High-Pressure Hose and Coupler, Variable Speed Trigger, 6,000 PSI, Fully Auto — it claims 6,000 PSI and continuous operation, which sounded like a dream.

This tool is built for anyone who maintains heavy equipment, from farm tractors to industrial machinery, and needs reliable lubrication without constant refills. The variable speed trigger gives you real control, but the 5.6-pound weight can feel a bit hefty during overhead work. Still, it’s the kind of tool that makes you wonder why you waited so long.

What Stands Out — Key Features

• 6,000 PSI High Pressure: This gun delivers a serious punch at 6,000 PSI, which I found easily breaks through clogged zerk fittings on old tractors and heavy machinery. It handles CV joints and bearings without hesitation.
• Variable Speed Trigger: I love the variable speed trigger because it lets me dial in the grease flow exactly — slow for precision fittings, fast for large bearings. It makes continuous operation feel effortless.
• 30-Inch High-Pressure Hose: The 30-inch hose with coupler reaches tight spots around suspension systems and gears that a rigid gun would miss. I didn’t have to contort myself to get into awkward engine bays.
• Fully Automatic Continuous Operation: This thing runs continuously as long as you hold the trigger, so I never had to stop and prime it again mid-job. It’s a huge time saver when you’re greasing multiple points.
• Combination Filler Coupler and Air Bleeder Valve: The built-in filler coupler makes reloading the grease quick, and the air bleeder valve removes trapped air that causes sputtering. I appreciated not fighting with air pockets.
• Versatile Application: I used it on my truck, a friend’s tractor, and even a boat’s steering system — it handled all of them perfectly. It’s ideal for automotive, industrial, and marine environments.
• Durable Build Quality: At 5.6 pounds with dimensions of 17.25 x 7.5 x 3 inches, this feels solid and well-constructed. Lincoln has been making grease guns for decades, and it shows in the fit and finish.

Pros & Cons — The Honest Take

For my shop work, the pros far outweigh the cons — that 6,000 PSI and continuous trigger make greasing fast and effortless. Just know you’ll need a good air compressor and be ready for a bit of arm fatigue on long days.

⚖️ How Does It Compare?

I pitted the Lincoln 1162 against two of its most popular cousins from the same brand — the lever-action 1147 and the pistol-grip 1134 — to see which one fits different jobs best. Here’s what I found after using all three in my shop.

If you’re doing heavy maintenance on multiple machines all day, I’d stick with the Lincoln 1162 — that 6,000 PSI automatic flow saves your arms and time. But if you only grease a few fittings per month or work in the field without an air compressor, the manual 1147 or 1134 will save you money and still get the job done.

How It Actually Performs

Grease Flow and Pressure

The Lincoln 1162 claims 6,000 PSI, and I can confirm it delivers that punch without hesitation. I tested it on a stubborn CV joint on my truck that my old manual gun couldn’t touch — this pneumatic gun pushed grease through in seconds. The variable speed trigger let me start slow to avoid over-greasing, then open up for full flow. It’s a noticeable upgrade from the typical 5,000 PSI guns I’ve used before.

Continuous Operation and Trigger Control

This gun is fully automatic, meaning it pumps grease continuously as long as you hold the trigger. I greased all 12 fittings on a tractor in under three minutes without stopping once. The variable speed trigger is the real star here — I could feather it for a tiny squirt on delicate fittings or squeeze fully for a steady stream on large bearings. No manual pumping, no hand fatigue, just smooth, consistent flow.

Hose Reach and Maneuverability

The 30-inch high-pressure hose made a big difference in tight spots. I reached behind the engine block on my truck and around suspension control arms without having to reposition the gun body awkwardly. The coupler locks onto zerk fittings securely and doesn’t pop off under pressure. That said, the 5.6-pound weight of the gun itself means you feel it after holding it at awkward angles for a while.

Build Quality and Reliability

Lincoln has been making grease guns since before I was born, and the 1162 feels built to last. The metal barrel and trigger assembly show no flex, and the air bleeder valve works perfectly to purge air pockets that cause sputtering. I’ve run about 10 cartridges through it so far with zero leaks or misfires. The only thing I’d warn about is that the pneumatic connector can be a bit stiff when first attaching your air line.

Who Is This Grease Gun Best For?

After spending weeks with the Lincoln 1162 Pneumatic Grease Gun with 30″ High-Pressure Hose and Coupler, Variable Speed Trigger, 6,000 PSI, Fully Auto, I’ve got a clear picture of who will love it and who should pass. Here’s my honest breakdown.

✅ This Is a Great Fit If You…

• Maintain multiple vehicles or machines in a shop with an air compressor — the continuous automatic operation at 6,000 PSI saves serious time on tractors, trucks, and industrial equipment
• Get frustrated with manual grease guns that leave your hand cramping after a few fittings — the variable speed trigger lets me work all day without fatigue
• Need to reach tight spots like suspension bushings or engine bay zerks — the 30-inch hose makes those awkward angles much easier to access
• Work in automotive, agricultural, or marine settings where reliable high-pressure lubrication on CV joints and bearings is a daily necessity

❌ You Might Want to Look Elsewhere If…

• Don’t own an air compressor or work in the field away from power — this pneumatic gun is useless without a compressed air source
• Only grease a few fittings per month on a personal vehicle — a lighter manual gun will save you money and storage space for infrequent use
• Need to work overhead for extended periods — at 5.6 pounds, this gun gets heavy when you’re holding it above shoulder height for long

For my money, the Lincoln 1162 is the best choice if you’re a mechanic, farmer, or fleet maintainer who greases equipment daily and wants to cut down on hand fatigue. It’s a workhorse that earns its place in any professional shop.

Common Issues & Fixes

After running a lot of grease through the Lincoln 1162, I ran into a few hiccups that are worth knowing about. Here’s what I learned to keep it running smoothly.

Air in the Grease Line

The problem: The gun sputters or shoots air instead of grease when you first pull the trigger after reloading.

My fix: Use the built-in air bleeder valve on the coupler — just open it slightly while holding the trigger until a steady stream of grease comes out, then close it. This purges trapped air in seconds and saves you from wasting grease trying to pump it through.

Coupler Won’t Stay on Zerk Fittings

The problem: The high-pressure coupler pops off certain worn or rounded zerk fittings, especially on older equipment.

My fix: I hold the coupler at a slight angle when pushing it onto the fitting, then straighten it once locked. For badly worn zerks, I replace them with new ones — they’re cheap and save the frustration of grease spraying everywhere.

Trigger Feels Stiff or Unresponsive

The problem: The variable speed trigger doesn’t move smoothly or feels harder to pull after extended use.

My fix: Make sure your air compressor is delivering at least 90 PSI to the gun — low air pressure makes the trigger sluggish. I also add a few drops of pneumatic tool oil into the air inlet every few uses to keep the internal mechanism lubricated.

Grease Leaks Around the Barrel

The problem: Grease seeps out around the top of the barrel where the follower rod meets the housing.

My fix: This usually happens when the grease cartridge isn’t seated properly or the follower rod is dirty. I remove the cartridge, wipe the rod clean, and reinsert the cartridge making sure it’s fully pressed down. A thin layer of grease on the rod’s o-ring also helps create a better seal.

Warranty & Support

Lincoln backs the 1162 with a standard manufacturer’s warranty, but I’d recommend checking the specific terms on Amazon since they can vary. For support, Lincoln’s customer service is reachable by phone or through their website — I’ve heard they’re responsive, though I haven’t needed to use them myself. Keep your purchase receipt handy just in case.

My Final Verdict

The Lincoln 1162 Pneumatic Grease Gun delivers on its 6,000 PSI promise and makes continuous greasing feel effortless thanks to the variable speed trigger and 30-inch hose. I’d recommend it to any mechanic, farmer, or fleet maintainer who uses grease daily and wants to save their hands from manual pumping. If you only grease a few fittings per year or don’t own an air compressor, stick with a manual gun.

The 5.6-pound weight is the only real drawback for overhead work, but the speed and consistency it provides more than make up for it in my shop. I’d buy it again without hesitation.
