Daily Care and Cleaning Checklist

Clean the fluid and air line filters

Warning: Megohmmeter Part No. 241079 (AA) is not approved for use in a hazardous location. Follow the safety instructions to avoid fire, explosion, and electric shock.

Flush and dry the fluid passage.

For Model L40M14, L40T14, L40M15, and L40T15 guns only: Is the resistance between the metal pin (GP) and the air swivel (21) less than 100 ohms?

For all guns: Is the resistance between the electrode needle tip (3) and the air swivel (21) within the specified range for your gun type?

Remove the power supply (11). Follow the steps in Power Supply Removal and Replacement, page 54.

Remove the alternator (15) from the power supply. See Alternator Removal and Replacement, page 55.

Is the resistance from the power supply’s ground strips (EE) to the spring (11a) within the specified range for your gun type?

Remove the electrode (3). See Electrode Replacement, page 50.

Is the resistance between the contact (HH) and the electrode wire (GG) between 8–30 megohms?

Prepare the Gun for Service (Refer to page 48)

Remove the power supply/alternator assembly and disconnect the alternator (Refer to Power Supply Removal and Replacement, page 54)

Measure resistance between the two outer terminals of the 3-wire connector (PC); it should be 2.0–6.0 ohms

If resistance is outside the 2.0-6.0 ohms range, replace the alternator coil (15a)

Using a flat blade screwdriver, pry the clip (15h) off the housing (15d). Remove the cap (15f), using a thin blade or screwdriver

If necessary, rotate the fan (15e) so its blades clear the four bearing tabs (T) of the housing (15d)

Push the fan and coil assembly (15a) out the front of the housing (15d)

Hold the coil assembly (15a) on a workbench with the fan end facing up. Using a wide blade screwdriver, pry the fan (15e) off the shaft (S)
