If the machine should start to vibrate abnormally, stop
the engine, disconnect the spark plug wire and ground it
against the engine. Inspect thoroughly for damage. Repair
any damage before starting and operating.

17.

Disengage all control levers and stop engine before you
leave the operating position (behind the handles). Wait
until the auger/impeller comes to a complete stop before
unclogging the chute assembly, making any adjustments,
or inspections.

18.

Never put your hand in the discharge or collector
openings. Always use the clean-out tool provided to
unclog the discharge opening. Do not unclog chute
assembly while engine is running. Shut off engine and
remain behind handles until all moving parts have stopped
before unclogging.

19.

Use only attachments and accessories approved by the
manufacturer (e.g. wheel weights, tire chains, cabs etc.).

20.

When starting engine, pull cord slowly until resistance
is felt, then pull rapidly. Rapid retraction of starter cord
(kickback) will pull hand and arm toward engine faster than
you can let go. Broken bones, fractures, bruises or sprains
could result.
