Grease guns

Many car components need to be regularly greased. For example, bearings, oil seals, universal joint cross and other parts. For this you should use the grease gun which supplies oil under the pressure. Thanks to it the agent is discharged efficiently, and the process of components treating becomes significantly easier.

Types of grease guns

By the working principle, there are such devices:

• Plunger. Lubricant comes out of the hole due to backward pressure created by the device spring mechanism. These devices have high pressure in the working chamber and are usually used for working with dense material and at low temperatures.
• Manual. These are inexpensive tools which deliver the lubricant at pressing the functional element and don’t have a spring. Intensity of material supplying is determined by amount of efforts made.
• Pneumatic. These are devices which function due to the built-in compressor which supplies pressed air. They can work from electrical mains or from the battery. They are characterized by high speed of lubricant delivery, but aren’t notable for low price.

The guns also differ in the body production material. Plastics or steel are usually used for its production. In catalogues of some manufacturers, there are devices with the reinforced shock-resistant frame.

Design

Depending on the type, the device can have such actuators as spring mechanism or the compressor. Moreover, the grease gun structure includes the case, elastic hose, rigid pipe, connection adapter, tip for agent delivery, sealing elements.

Some models are equipped with changeable caps of different diameters, additional flexible pipes for treating hard-to-reach places. Also, there can be the product discharge regulator, function of automatic air removal from the body, and others.

Tips on grease gun use

Performing of lubricating works should be entrusted to service station specialists. In case of operating the pump by yourself, following safety regulations is important:

• Adhere to manufacturer’s instructions and don’t use the device with the materials it is not made for.
• Before starting works, make sure that the device is not damaged.
• Use equipment for eyes and skin protection.
• Don’t use the device near fire sources.

After completing the works the tool should be cleaned, and the dosing cap should be wiped only with lint free cloth. The device should be stored in a dry room at the temperature not lower than +5 °C. It is important to avoid dust getting onto the device elements.
