TROUBLESHOOTING

There is an auto-greasing warning lamp and injector actuation indicator at the position to inform of abnormalities in
the auto-greasing system.
AUTO-GREASING WARNING LAMP (RED)
If there is any abnormality in the pressurization of the grease line,
the buzzer sounds and the warning lamp (red) lights up.
INJECTOR ACTION INDICATOR
The indicator pin moves up and down according to the increase or
decrease in pressure in the grease line to inform the operator that
grease is being supplied to the greasing points. If the grease is not
being supplied normally, the indicator pin does not move even
when the pressure increases or decreases, so it is possible to
detect the abnormality.
