8. Cleaning/Maintenance
WARNING : All cleaning operations must be done only with depressurized compressed air with
a 2,5 bar maximum pressure, a cloth or a brush, if necessary. Never use water or solvents to
clean equipment, with the exception of the deflector.
Fouling and wear of the Mach Jet spray gun caused by the passage of powder vary according to
operating conditions and the type of powder used.
For this reason, the maintenance frequency indicated here is given as a guide only. With a little
experience of using SAMES equipment, the user will be able to draw up his own maintenance schedule.
Nevertheless, as an initial guide, the following maintenance programme is recommended:
Frequency
Action
Before starting work
Check the safety regulations.
Every 8 hours
Switch off the “CRN 457” mains power supply, disas-
semble and clean the nozzle and compressed air elec-
trode. Make sure that there is no accumulation of
powder on the electrode.
Clean the powder ducts by blowing compressed air
through the powder end-piece below the handle
assembly without disassembling it.
Between 40 and 60 hours of work
Clean the round spray deflector by leaving it to soak for
a few hours in methyl-isobutyl-ketone (MIBK)*.
From 3 to 6 months
Check the state of wear and soiling of the powder
elbow, replace it if necessary.
WARNING : * MIBK solvent is toxic and flammable.
