Maintenance
Generator Capacitor
Replacement
The capacitor located in the rear of the generator
controls and regulates the voltage in the generator while
in operation. If this capacitor fails, the voltage will drop to
little or no output at all.
Replacing this capacitor with one of the same type and
value will help determine if the capacitor is at fault.
1. Ensure that the paver and generator engines are off.
2. Detach the wires at the top of the capacitor.
3. Remove the capacitor and replace with a new one
of the same type and value.
4. Re-attach the leads at the top of the capacitor.
There are no other voltage adjustments that can be
made to the generator.
Testing Element Relays
The element relays are 12VDC controlled, and have dual
contacts rated for 240VAC.
1. Disconnect any wires to the relay, or completely
remove it from the control box (Figure 7-15).

2. Place the leads of an ohm meter, or continuity tester
across the contact terminals (2 to 4) or (6 to 8) as
shown in Figure 7-16.
There is a ow control adjuster (Figure 7-14,1) provided
on the front of the manifold. This adjustment controls
speed of the generator and should only be made by an
authorized LeeBoy dealer.
Improper adjusting will overspeed
generator.

To Fine Tune Generator Speed:
Over adjustment will cause damage to
the generator and void the warranty.
NOTE: Generator Speed should only be adjusted by an
authorized LeeBoy dealer.
• Locate the Flow Control Adjuster (Figure 7-14,1) and
turn to increase or decrease the speed as needed.
NOTE: Clockwise (CW) adjustment will slow the
generator down.
Counter Clockwise (CCW) adjustment will speed
the generator up.
If your generator will not operate at the correct speed
it may be necessary to test the hydraulic ow from the
pump, or check the generator motor for excessive case
drain ow. The case drain of the motor should not leak
more than 1 gallon per minute. Replace the generator
motor or paver pump if either are found to be operating
incorrectly.
