types of commercial solvents and may be damaged by their use. Use clean clothes to remove dirt, dust, oil,
grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-based products, penetrating oils, etc.,
come in contact with plastic parts. Chemicals can damage, weaken, or destroy plastic, which
could result in serious personal injury.

slack on the underside of the guide bar, the chain is snug, but
it can be turned by hand without binding.
