HOUR METER
The DGI® TACH/HOUR hour meter tracks the hours of machine operation in order for routine
maintenance to be performed on a timely basis.
Your DGI® hour meter is pre-set at the DGI® factory to go into Flash Alert mode at 25-hour
intervals. Although the engine manufacturer does not require changing engine oil this often, due to
heavy-duty use and extreme conditions inherent to 3107C use, Barreto Manufacturing strongly
recommends frequent oil changes.
Refer to this manual for equipment service requirements and to the Engine Manual for other engine
service requirements.
While Flash Alert is active, hold the tip of the RESET TOOL (Key Kancel Wand) against the meter
as shown. Within several seconds the display will stop flashing indicating the Service Interval has
been reset. If the wand gets lost, a small mechanic’s pick-up magnet will reset the meter.
