Maintenance Tips

"Daily inspection (every 10 hours): Before starting each shift, visually inspect the screen display and buttons, remove dust, strictly prohibit the use of hard objects or corrosive solvents to wipe the screen, and check whether there is a black screen, flashing, or communication bus fault code during the power on self-test.

Physical dust and moisture prevention (every 250 hours): Check and clean the cabin air conditioning filter every 250 hours, clean the heat dissipation grille on the back of the monitor, and prevent conductive mining dust and trace moisture from entering the internal precision microcomputer motherboard.

Electrical link clearance (every 1000 hours): no more than 1 year (or 1000 hours), conduct a thorough inspection of the main harness connectors behind the dashboard. Check the voltage stabilization status of the battery and the generator voltage (strictly prevent overvoltage breakdown), and strictly control the electrochemical damage to the chip caused by black box static electricity and surges."

Installation Tips

"Power off installation (core avoidance pit): Before any disassembly or installation operation, the main power switch of the entire vehicle must be forcibly cut off (or the negative lead of the battery must be disconnected). It is strictly prohibited to plug and unplug electrical connectors with electric heating, otherwise the instantaneous surge electromotive force will cause irreversible physical erosion of the internal communication chip within 0.1 seconds.

Anti static and stress free fastening: Operators should release static electricity before assembly. When fixing the display panel to the cab bracket, all high-strength fixing screws must be symmetrically and cross tightened in stages using a micro torque wrench to prevent excessive unilateral force from causing slight stress deformation of the plastic shell of the display, which may cause local compression color deviation or backlight cracking of the internal LCD screen."
