TC-12 TREE CHIPPER OPERATING INSTRUCTIONS
To disengage the clutch, set engine speed below 1200 rpm and push the “Engage/Disengage Button”. The clutch will
immediately disengage.
The controller will allow 3 failed clutch startup attempts in a row. After the 3
rd
failed clutch startup attempt, the
controller will prevent the clutch from being engaged for 10 minutes.
There are three different conditions that are considered as “failed start attempts”. They are:
• The engine speed goes to zero and the engine stalls while the clutch is engaging.
• The operator attempts to increase engine speed while the clutch is engaging.
• The operator pushes the green engage/disengage button to disengage the clutch while the clutch is
engaging.
If there is a pressure loss while the clutch is engaged, the controller will disengage the clutch and the “Oil Pressure Loss
Symbol” will ash to indicate that there was a pressure loss while the clutch was engaged.
