Maintenance - Ryobi RY15122 Manuel D'utilisation

WARNING:
Before inspecting, cleaning, or servicing the machine,
shut off engine or motor, wait for all moving parts to stop,
and disconnect spark plug wire and move it away from
spark plug or disconnect from power supply. Failure to
follow these instructions can result in serious personal
injury or property damage.
WARNING:
Always wear eye protection with side shields marked to
comply with ANSI Z87.1. Failure to do so could result in
objects being thrown into your eyes, resulting in possible
serious injury.
WARNING:
When servicing, use replacement parts that meet or
exceed original product specifications. Use of any other
parts could create a hazard or cause product damage.
NOTICE:
Periodically inspect the entire product for damaged,
missing, or loose parts such as screws, nuts, bolts, caps,
etc. Tighten securely all fasteners and caps and do not
operate this product until all missing or damaged parts are
replaced. Please contact customer service or a qualified
service center for assistance.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths 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 de-
stroy plastic which could result in serious personal injury.
