Experience of LockNLube Grease Gun

[wptb id=1777]

I got many wrenches to remove the end fitting from Linclon 1162 gun. I need to offer gratitude to Lincoln in light of screwing the fitting onto the male strings utilizing two or three hundred-foot pounds of force. Using many curse words and 2 pipe wrenches, luckily I finally got the Lincoln fitting and screwed the LockNLube Grease Gun onto the end of the hose, snugging it with a crescent wrench. The activities of the thumb lever to increase the collet is flexible, easy, and smooth.

 I was incredibly associated with the measurement of the terminal and it impeccably fits. Wherever including pins at the can end of the FEL where the zerk is in a counterbore into the U-joint and on the sleeve to contact the zerk fitting area. Tap on the thumb lever, release, and slip the collet over the zerk. Every last bit and pump grease goes into the fitting and there is no leakage. Release the thumb lever and the cap removes from the zerk easily, and there is no resistance at all. I gained on all the grease points for the FEL and those under the machine and gives it the same result, no fuss, no muss. For me, the cost which included free shipping was worth it.

Very easy to use

I have wasted a huge amount of grease on fittings and am always concerned that I was not getting sufficient grease into the U-joint which bears failure early. This tool plays the trick very easily. It is constructed perfectly, use very easily, and does accurately. I don’t like the grease for a lot of time. They are messy and stray grease every time jump on me. To get the grease effortlessly, where you want it. Without hold and release the hose makes me like my gun, a lot better. You grease your machine otherwise you have to pay a high price later. It makes your life easier and helps you to complete your task easily.
