Common signs of failure / service requirement:

• Trim or tilt does not operate in either direction

• Motor clicks, turns slowly or draws excessive current

• Intermittent operation caused by worn brushes or corroded wiring

• Hydraulic pump works only when the motor is struck or cooled

• Water intrusion, corrosion or a burnt electrical smell
