Product Description

Product Description

Q: what is it?

This item is a manual grease gun, a commonly used lubrication tool in mechanical maintenance. Key information is as follows:

Structure
Main body: Blue grease reservoir (for holding grease), metal pressure rod (provides pressure), handle;
Accessories: Black high-pressure hose (connects gun head to grease fitting), metal grease fitting nozzle (inserts into machine grease port).

Function and Usage
Used to apply lubricating grease to bearings, hinges, and other components of mechanical equipment to reduce wear and tear;
Operation involves loading grease into the reservoir, then pressing the handle to leverage hydraulic pressure. Grease is then delivered through the hose and nozzle to the lubrication point.

Applications
Commonly used in automotive repair, agricultural machinery maintenance, industrial equipment upkeep, and other scenarios. Suitable for all types of mechanical components requiring grease lubrication.  

Q: how do I use?

Here are the correct steps for using a manual grease gun:

Filling with grease: Unscrew the rear cap of the grease reservoir, fill the cylinder with grease (or draw grease through the front suction port), expel any air, then tighten the cap.

Connecting fittings: Attach one end of the high-pressure hose to the front of the grease gun and the other end to the grease nozzle.

Air Bleeding: Press the trigger several times until grease flows from the nozzle tip (to expel air from the line).

Greasing: Align the nozzle tip with the machine's grease fitting and secure it. Repeatedly press the trigger until grease fills the lubrication point.
Finishing: After greasing, remove the nozzle tip. Clean residual grease from the hose and nozzle tip, then store properly.

Q:I need a troubleshooting guide for common issues.
 

Malfunction Symptom	Common Causes	Troubleshooting Methods
No grease discharge	1. Air trapped in the grease cylinder 2. Grease clumping 3. Clogged pipeline	1. Re-bleed air 2. Replace with softened grease 3. Disassemble and clean the hose/nozzle
Low grease output	1. Worn seal of the lever 2. Excessively high grease viscosity	1. Replace the seal 2. Use low-viscosity suitable grease
Grease leakage from the nozzle	1. Poor seal between nozzle and grease fitting 2. Damaged nozzle seal	1. Re-secure the nozzle 2. Replace the nozzle seal
Stuck lever (cannot press)	1. Hardened grease 2. Grease cylinder overfilled	1. Preheat to soften the grease 2. Pour out some grease to leave space

	Part Name	Core Function
	Grease Gun Lever	It is manually pressed to generate pressure, which drives the transmission mechanism inside the grease gun to push the grease outward.
	Grip Handle	It is used for operators to hold the grease gun firmly, making it easier to apply force when pressing the lever.
	Grease Cartridge / Barrel	It serves as a container for storing lubricating grease and provides a stable space for the grease to be pushed and conveyed.
	Rear Cap	It seals the tail of the grease cartridge. It can be unscrewed when filling grease, and it also helps to fix the internal piston and spring structure.
	Piston Rod	It is connected with the internal piston of the grease cartridge. When force is applied, it pushes the piston to move forward, so as to continuously push the grease in the cartridge to the output end.
	High - pressure Hose	It connects the main body of the grease gun with the grease coupler. It can withstand the high pressure generated during grease injection and transmit the grease smoothly.
	Grease Coupler / Nozzle	It is connected with the grease fitting of the mechanical equipment. It has a sealing and clamping structure to ensure that grease will not leak during injection and realize accurate grease filling.
	Internal Spring	It is usually arranged between the piston and the rear cap. It assists the piston rod and piston to reset after each pressure application, maintaining the stability of the grease pushing rhythm.
	Bleeder Valve	It is generally installed on the gun head. It can discharge the air trapped in the grease cartridge or the pipeline, avoiding the situation that grease cannot be discharged due to air blockage.
