Haier 309292L User Manual

Electrical components inside the gun affect performance 
and safety. The following procedures test the condition 
of the power supply (18) and electrode (29), and electri-
cal continuity between components.

Use megohmmeter Part No. 241079 (AA) and an 
applied voltage of 500 V. Connect the leads as shown.

1.

Flush and dry the fluid passage.

2.

Measure resistance between the electrode needle 
tip (29) and the air swivel (35); it should be 117-137 
megohms for the PRO Xs3, and 156-180 megohms 
for the PRO Xs4. If outside this range, go to the next 
test. If in range, refer to Electrical Troubleshooting 
on page 23 for other possible causes of poor perfor-
mance. 

Megohmmeter Part No. 241079 (AA-see 
F

. 6.) is not approved for use in a hazard-

ous area. To reduce the risk of sparking, do 
not use the megohmmeter to check electri-
cal grounding unless: 

• The gun has been removed from the 

hazardous area;

• Or all spraying devices in the hazardous 

area are turned off, ventilation fans in the 
hazardous area are operating, and there 
are no flammable vapors in the area 
(such as open solvent containers or 
fumes from spraying).

Failure to follow this warning could cause 
fire, explosion, and electric shock and result 
in serious injury and property damage.
