I always carry a spare vac motor, mounted on a frame
which can sit ontop of my Powrflite so can finish the job
before changing motor.
2x male and female Qds
Spare wire and crimp connector kit.
spare machine hoses in case of catastrophic failure.
Spare Pumptec 205 head and eccentric bearing.
vac motor brushes , K valve , hide a hose valve.
Handtool valve for stair tool,
Spare switches in fact just about everything except
a 1/2 horsepower pump motor.
My toolkit includes all spanners and screwdrivers necessary
to do any repair, plus electrical test meter.
In fact the one thing i don't carry is my SPARE MACHINE!!!
