Pneumatic Grease Gun from Harbor Freight Air Grease Gun

GET THE AIR OUT. New Pneumatic Grease Gun from Harbor Freight. Fill and bleed air on first use.
I read some product reviews for this tool and it seemed some folks had problems bleeding the air out and getting it to work the first time or after changing the cartridge. This is how I did it. It may be overkill. But, it worked for me.

The trigger is a little flimsy and I may have to modify it. Other than that, it works fine.

Update: I've gone through two cartridges of grease without any failure or major complaint.

Just useful info: The grease fitting at the end of the grease gun hose is threaded on and you can loosen or tighten it's grip on the zerk fitting buy twisting it where its is knurled. Nice to know if it becomes stuck on the zerk fitting or won't stay on the zerk fitting. Most grease guns are designed this way.

If the part won't take any grease because the zerk fitting is clogged, remove it and clean it out with a twist drill or replace the zerk fitting with a new one.
