Frequently Asked Questions
How do cordless grease guns work?
The main working mechanism involves high levels of air pressure, which serve as a driving force.
High levels of pressurized air put pressure on the air piston which further drives the grease piston and forces the lubricant out of the coupler into a grease fitting.
By letting go of the trigger slowly and gradually, the machine produces a steady flow of lubricant.
What are cordless grease guns used for?
A cordless grease gun’s main function is to reduce operator fatigue and de-clutter the work station of the user.
Additionally, the main usage is to ensure efficient and specific lubrication at a particular ‘nipple’ point.
How many PSI does a grease gun produce?
Different models produce different PSI measurements due to specifications and features.
However, the consensus claims that most grease guns produce several thousand PSIs, with the lowest roughly being around 1500 and the highest going up to about 17000PSI.
How do you load a grease cartridge?
Loading a grease cartridge can be broken down into about five steps.
First, you have to unscrew the cartridge cap.
Pull back on the metal handle and secure the piston rod, further removing the cartridge.
Now, just prepare the cartridge and insert it into the barrel.
What is a grease gun used for?
The main purpose of using a grease gun is for the process of lubrication.
The main reason this tool is employed is that it saves the user a lot of time and can be specified to be consistent when applying grease to a particular aperture.
Furthermore, they are also quite inexpensive.
How much is a shot of grease?
The shot of grease refers to the output of a grease gun and is generally measured by how much is pumped out in one round.
Since different models are made differently, the shot measure is different.
However, the range lies from 0.1 ounces to 2 or 3 grams.
How do you store a grease gun?
The cartridge tubes should always be stored in a vertical position for maximal efficiency and durability.
However, if the cartridge is inside the gun, then the best way to go about it is by first depressurizing the gun, cleaning it with a cloth to avoid contamination and then storing it horizontally to prevent the oil bleeding out of the grease.
What is grease made of?
Generally speaking, grease is made of a soap that is emulsified with either mineral or vegetable oil.
The soapy bit is also referred to as a thickener. About 10% of grease is additives which give grease their useful properties.
The rest of it, as mentioned above, is purely a thickener and oil.
Why is grease bad for you?
Grease is often linked with very high and saturated levels of fat.
Once ingested, the sheer amount of fat present in our body is overwhelming and makes the collective process difficult.
As time goes on, the efficiency of the digestive system decreases, which might often lead to nausea and vomiting.
Does grease evaporate?
Since grease is a semi-solid liquid, there’s a general ambiguity about what would happen when it’s exposed to high temperatures.
Made out of many components, an essential ingredient for grease is mineral oils. At temperatures higher than 177C, the mineral oils present evaporate.
Excessive evaporation hardens the grease.
