12v DC Electric Motor
The motor used on a battery-powered Multi-Tip is an 800 watt, series-wound 12v DC motor. It has
4 brushes which wear down over time; as they are difficult and time-consuming to replace, it is
usually better to fit a complete new motor.
Positive supply to the motor comes through the relay mounted on the side of the motor (see
section 4.6); negative is permanently connected to the motor terminal.
Removal and Refitting
I.
Remove the entire power pack as described in section 5.2.
II.
Undo the 2 cap screws holding the motor to the power pack and lift it away.
III.
The power pack must be held vertical when refitting the motor; ensure the coupling
engages correctly with the pump shaft.
