7. MAINTENANCE
Periodic inspection and maintenance will help extend the service life of
your HS521 Snowthrower while keeping it in the best operating condition.
Inspect or seivice as described on the next page.
l Shut off the engine before performing inspection and maintenance, and
disconnect the spark plug wire from the plug so the engine cannot be
started.
l If the engine must be run, make sure the area is well ventilated. Exhaust
gas contains poisonous carbon monoxide; exposure can cause loss of
consciousness and may lead to death.
l To avoid overturning, place the snowthrower on a level surface before
performing inspection and maintenance.
l Use only genuine HONDA parts or their equivalent.
Replacement parts which are not of equivalent quality may damage the
snowthrower.
