LUBRICATION
Bearings used in the motor, gearbox and drive wheels are sealed and require no
lubrication. All other moving parts except for the Locking Teeth should be lightly
oiled with a medium weight oil such as automotive type SAE 30.
Use care when applying oil as excessive
oil could drip on the tracks, causing a
safety hazard on stairs. The Locking
Teeth should always have a thin film of
lightweight grease at the points shown.
