Operation
the trencher does work best if you set it close to
nine o'clock so that the traction unit will creep
slowly when trenching.
Note: The flow divider control can be fixed
in place by turning the knob on the
control clockwise until it contacts the
dial (Fig. 13).

Indicator Lights

The indicator lights warn you in the case of a system
malfunction and, in the case of the glow plug light,
indicate that the glow plugs are on. Figure 14
illustrates the four indicator lights.

required and replace any worn or slipping belts. If
the problem persists, contact your Authorized Toro
