Troubleshooting
NOTE:
The sprayer operates using air pressure. Many
problems are caused by inadequate air supply. The inlet
air pressure gauge cannot drop below 50 psi (0.35 MPa,
3.5 bar) while running.
NOTE:
If an error code displays, see manual XM
sprayer operation manual.
1. Follow
, page 17,
before checking or repairing the gun.
2. Check all possible problems and causes before
disassembling gun.
To avoid injury due to unexpected machine operation
initiated by a remote controller, disconnect the
customer I/O cable from the system prior to
troubleshooting.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the
on page 17 when you stop pumping and
before cleaning, checking or servicing the equipment.
