Detailed introduction
1. Product Introduction
1.1 Product Overview
The explosion-proof automatic greaser is an independent oil supply device. It runs a small reducer according to the time stored in the microprocessor, drives the worm gear inside the pump, and sucks/sprays the grease in the container through the reciprocating motion of the vertical piston.
This product adopts an explosion-proof electrical device structure to ensure that electrical equipment can operate normally in a potentially explosive environment and prevent the ignition of surrounding explosive gases under abnormal conditions. Its circuits and components are all automatic oilers made based on the explosion-proof principle.

Note: The oil injection amount per stroke of the oil injector is 0.34ml at 20℃. The amount of grease injection will be affected by factors such as temperature, air pressure, and grease concentration. If the average temperature is different, please select the appropriate oil injection cycle according to the actual situation on site.
4. Installation and debugging
4.1 Installation methods
Direct installation and remote installation

4.1 Installation steps and precautions
1. Before installation, confirm whether the grease of the lubricator meets the lubrication requirements of the equipment;
2. Before installation, clean the dirt around the lubrication point, and use a manual grease gun to dredge the oil circuit if necessary;
3. During installation, each connection point needs to be sealed to prevent oil leakage;
4. If there are vibrations, overheating, unsafe operation locations, etc. during use, it is recommended to use remote installation.
4.2 Debugging
1. Long press the POWER button to turn on the machine and confirm that the display is normal;
2. Start the test mode to test whether the lubricator is operating and greasing normally. The test can be ended manually (refer to 3.2 button instructions);
3. Select the grease bag capacity and set the greasing cycle. When entering the locked state, the greaser will work normally according to the settings;
4.3 Remote installation accessories (optional)

5. Spare kit
5.1 Spare kit description
1. The spare kit includes: grease pack (125ml or 250ml), battery pack (4.5V alkaline battery pack), and dust cover.
2. It is recommended to replace the grease pack and battery pack at the same time to ensure sufficient power.

5.2 Steps and precautions for replacing the kit
1. Before replacing, please make sure it is in the off state;
2. There is a spring in the top cover. Please pay attention to the elastic force when removing and installing the top cover;
3. After installing the new battery pack, rotate the battery pressing piece to press the battery pack firmly;
4. Before replacing the grease bag, press the grease bag to make a small amount of grease overflow from the outlet, and then tighten it to the interface;
5. After replacing the kit, perform the clear data operation (refer to 3.2), and then re-debug;
6. After debugging, put on the dust cover;
6. Fault and alarm
Causes of the phenomenon and treatment
The motor stall indicator lights up. Grease hardening, grease overflow, pipe blockage, pipe length, etc. will cause excessive back pressure, resulting in motor stall. Confirm the back pressure level;
You can use a manual grease gun to pressurize and unclog the pipe;
Shorten the length of the connecting pipe;
The indicator light flashes continuously. When the oil filling cycle ends, the battery is low, the motor stops or the grease is insufficient, the indicator light will flash continuously (frequency 1Hz). Please follow the instructions to check the equipment status;
(Refer to 3.2 Display Instructions)
