6.3 Precautions and Solutions to Common Problems

6.3.1 Precautions
1） The transparent tubes are made of glass. So, do not place other items around the device to avoid scratching
and fragmenting the tubes.
2） Disassembly of the tubes should be performed after the system pressure is displayed as zero.
3） It must be ensured that the power supply provided is grounded well.
4） Take good care of the machine. If the protective film on the control panel is stained with cleaning agent,
please wipe it off in time. Also, keep the pulse signal lines away from the cleaning agent and test solution.
Warning!
Blind and imprudent overhauls can lead to the expansion of the fault area of the device, causing difficulties for
formal maintenance. When the device is powered on, the electrical system inside the machine contains factors
that can cause danger! Careless operations can result in personal injury accidents, which can lead to physical
disability and even death in serious accidents.
6.3.2 Solutions to Common Problems
1. No response on startup
Check if the fuse at the bottom right side of the machine is damaged. If it is damaged, please change it.
2. Fuel leak at coupling element of fuel distributor
Fuel leaked at coupling element of fuel distributor. Please check whether the "O" ring installed matches and if it
deformed or damaged. If it does not match or is damaged, please change it. The two adjusting screws should not
be too tight, which may also cause the coupling element of fuel distributor to leak fuel.
3. Test solution in the transparent tubes can be drained completely by pressing [Drain] button twice.
The solenoid valve of the machine has a 60-second automatic shutoff function; Multiple drainages may be
required if there is a large amount of test solution in the transparent tube.
