Residual Risk; Risk Reduction - Ryobi RCS5133CB Original Instructions Manual

●
For a more thorough cleaning, clean in warm soapy
water. Rinse and let dry completely.
●
Replace with a new air filter after every 25 hours
of use.
NOTE: An alternative method is to clean the air fi lter with
compressed air (always wear eye protection to avoid eye
injury).
6. Reinstall the air filter, making sure that the tabs on the
air filter are properly aligned and positioned.
7. Reinstall the air filter cover. Push down on the knob and
rotate clockwise to secure.
8. Clean the pre-filter every 25 tanks of fuel or sooner, if
required. Remove the engine cover, starter assembly,
and fan housing baffle for access to the pre-filter in the
engine housing. (See page 335 - 337.)
NOTE: If you use an air hose for drying, blow through both
sides of the fi lter.
WARNING
Never run the engine without the air fi lter. Make sure the
air fi lter is correctly placed in the air fi lter cover before
reassembly.

RESIDUAL RISK

Even when the product is used as prescribed, it is still
impossible to completely eliminate certain residual risk
factors. The following hazards may arise in use and the
operator should pay special attention to avoid the following:
■
Injury caused by vibration. Always use the right tool for
the job, use designated handles and restrict working
time and exposure.
■
Exposure to noise can cause hearing injury. Wear ear
protection and limit exposure.
■
Contact with exposed saw teeth of the chain (cutting
hazards).
■
Unforeseen, abrupt movement or kickback of the guide
bar (cutting hazards).
■
Parts ejected from the saw chain (cutting/injection
hazards).
■
Thrown out pieces of the work piece (wood chips,
splinters).
■
Inhalation of saw dust and particles or emission from
the petrol engine.
■
Skin contact with petrol/oil.

RISK REDUCTION

It has been reported that vibrations from handheld tools
may contribute to a condition called Raynaud's Syndrome
in certain individuals. Symptoms may include tingling,
numbness and blanching of the fi ngers, usually apparent
upon exposure to cold. Hereditary factors, exposure to
cold and dampness, diet, smoking and work practices
are all thought to contribute to the development of these
symptoms. There are measures that can be taken by the
operator to possibly reduce the effects of vibration:
■
Keep your body warm in cold weather. When operating
the product wear gloves to keep the hands and wrists
warm. It is reported that cold weather is a major factor
contributing to Raynaud's Syndrome.
■
After each period of operation, exercise to increase
blood circulation.
■
Take frequent work breaks. Limit the amount of
exposure per day.
