5. To separate the power supply (7) from the turbine
(8), disconnect the 3-wire ribbon connector (PC)
from the power supply. See F
IGURE
32.
Smart models only:
disconnect the 6–pin flexible
circuit (30) from the power supply.
Slide the turbine up and off the power supply.
6. See
Test Power Supply Resistance
, page 22.
Replace the power supply if necessary. To repair
the turbine, see
Turbine Removal and Replace-
ment
, page 34.
7. Connect the 3-wire ribbon connector (PC) to the
power supply.
Smart models only:
connect the 6–pin flexible cir-
cuit (30) to the power supply.
Tuck the ribbon forward, under the power supply.
Slide the turbine (8) down onto the power supply
(7).
8. Insert the power supply/turbine assembly in the gun
body (10). Make sure the ground strips (EE) make
contact with the handle.
Smart models only:
align the connector of the
6–pin flexible circuit (30) with the socket (CS) at the
top of the handle. See F
IGURE
32.
Push the connector securely into the socket as you
slide the power supply/turbine assembly into the
handle.
9. Make sure the gasket (9), ground spring (6), and
power supply spring (7a) are in place. Replace gas-
ket (9) if damaged. Assemble the barrel (1) to the
gun body (10). See Barrel Installation, page 42.
10. See
Test Gun Resistance
, page 22.
Turbine Removal and
Replacement
NOTE:
Replace turbine bearings after 2000 hours of
operation. Order Part No. 24N706 Bearing Kit. Parts
included in the kit are marked with a symbol (
). See
F
IGURE
33 through F
IGURE
36.
1. See
Prepare the Gun for Service
, page 28.
2. Remove the power supply/turbine assembly and
disconnect the turbine. See
Power Supply
Removal and Replacement
, page 33.
3. Measure resistance between the two outer termi-
nals of the 3-wire connector (PC); it should be
2.0–6.0 ohms. If outside this range, replace the tur-
bine coil (8a).
4. Using a flat blade screwdriver, pry the clip (8h) off
the housing (8d). Remove the cap (8f), using a thin
blade or screwdriver.
5. If necessary, rotate the fan (8e) so its blades clear
the four bearing tabs (T) of the housing (8d). See
F
IGURE
34.
NOTICE
To prevent damage to the cable and possible inter-
ruption of the ground continuity, bend the turbine’s
3–wire ribbon cable (PC) upward and back, so the
bend faces the power supply and the connector is at
the top.
