(Refer to Figure 22)
3. Cover the front of the barrel (Item 6) with a rag. With an
air gun (set at a maximum of 3 bar/50 psig) at the rear of
the resistor housing, blow the resistor seal (Item 3), o-ring
(Item 2), and resistor (Item 4) out the front of the barrel.
1. Remove the cable/motor assembly per steps 1 and 2
of “Cable Assembly Replacement” in the “Maintenance”
section. Remove the brush (Item 1) from the resistor
housing (Item 5).
2. Insert a long shaft standard screwdriver into the lower
opening at the rear of the barrel assembly and remove
screw (Item 8) and washer (Item 7).
4 Clean the resistor housing (Item 5) with a nonconductive
solvent and dry thoroughly. (Refer to “Effects of Solvents”
in the “Maintenance” section.) Inspect the ID of each end
of the resistor tube for any signs of high voltage tracking
or arcing.

Resistor is made of ceramic material. Resistor will
break if dropped, mishandled, or exposed to solvents.
If resistor is not pushed out by the air, insert a rigid
wire into the rear of the resistor housing and push the
resistor out. Be careful not to scratch or scar the inside
of resistor housing.
If any such damage is found the resistor housing (Item 5)
needs to be replaced. Contact an authorized Ransburg
representative to replace the resistor housing if damaged.
After two to four resistors failing, the resistor hous-
ing may be permanently contaminated and require re-
placement.
