Avoid contamination at the lubrication points. Contamination and sand in
the bearing points lead to premature wear.
Grease gun and grease nipples must be cleaned before lubrication.
Only use the lubricants listed and never mix different types, as some
greases are not compatible with each other. They gum up and the
lubricating effect decreases drastically.
In addition, follow the enclosed manufacturer's instructions for the motor,
axle and carriage shaft.
