There are three main kinds of grease guns, which are by hand, air, and electricity.

  • By Hand – It is also called manual grease gun. It’s simply operated by squeezing the handle and thus controls the force and flow rate. Lever type, one hand operation and push type are all commonly used globally.
  • By Air – Air operated grease gun (Pneumatic grease gun) which is only operated when it is connected to air compressor through the hose. In the market, there are two types, single shoot, and continuous flow.
  • By Electricity – Also called cordless grease gun or Battery-powered grease gun.
    This kind of grease gun is suitable for someone who works in some area where their hands are not available for priming the lever, or there is no air compressor such as priming on the Wind turbine.

A different kind of grease gun serves different purposes. In fact, we provide various types of grease gun and also customization.
Now, let’s explore for more details.

Grease Gun Application
Grease gun is commonly found in the area which includes joint, bearing and other hard to reach area, examples include:
  • Auto, Aviation, Ship Maintenance
  • Construction Machine
  • Agricultural
  • Aerospace Industry
  • Wind Turbine
  • Factory processing systems
  • Gardening
Regular maintenance by priming the grease into those areas enable the expensive and heavy machine more precise and smooth, not to mention increasing the service time.

Generally, mostly grease gun can be loaded with cartridge and bulk loading. However, if grease gun is equipped with the filler plug, then, you can use the grease filler pump to fill in the grease.
Below you can find each loading way instruction:

1. Loading with cartridge
(a) Remove the gun head from the container tube.
(b) Draw back the plunger rod entirely
(c) Insert the open-end of cartridge into container tube and push all the way in.
(d) Remove the seal or pull tab end from the cartridge
(e) Reassemble the gun head to container tube.
(f) Release the plunger rod and push into the container tube.

2. Loading with filler plug
(a) Draw back the plunger rod entirely
(b) Operate the filler pump to fill the container tube through filler plug.
(c) Disconnect the grease gun from the filler pump.
(d) Release the plunger rod and push into the container tube.

3. Bulk loading
(a) Remove the gun head from the container tube.
(b) Draw back the plunger rod entirely
(c) Fill the bulk grease into empty container tube
(d) Reassemble the gun head to container tube.
(e) Release the plunger rod and push into the container tube.

There are many kinds of grease.
Depending on the usage or area, lithium grease, synthetic grease, food grade grease, etc. are all perfect for priming.
Distinguished by the NLGI consistency number, it has 9 grades from grade 000, 00, 0,1 to grade 6. When the grade is higher, the grease is thicker.
Basically, users can use different grease for different purposes.
However, if speaking of the viscosity part, NLGI GRADE 1-2 is generally recommended.
In that way, the grease is perfect for priming, not too hard to prime but not to watery.

Many users may face a problem like this. The container is still full of grease, but no matter how hard we try, how much time we prime. The grease won’t come out. Why does this happen? The air pocket may take major part of the reason. But how to remove the air pocket? Here are the instruction steps, following it and the air pocket will be removed:
  • Remove the spout or any accessories out of gun head.
  • Unscrew the gun head 1-2turns until 1-2 threads appear.
  • Prime the grease gun until the grease out.
  • Screw the gun head tightly and the accessory.
  • Ready for use.
What if when you have followed the above instruction, but it is still not working, please do not disassemble the grease gun and send to the shop that you purchased for assistance as soon as possible.

Step 6

Unscrew gun head 1-3 turns and pump the lever handle around 6-8 times until grease comes out. This releases air pockets from barrel and makes it easy to pump the grease

Step 7

Screw the gun head tightly and ready for priming.

Trouble shooting

Problem: Gun not pumping grease
Possible causes: Air pocket between in the tube and gun head,or between in the gun head and spout.

Solution:
  1. Take off spout from gun head.
  2. Unscrew container tube 1-2 turns from gun head.
