Sound Pressure; Sound Power; Vibration, Hand/Arm - Hayter R48 447F Operator's Manual

– Do not mow excessively steep slopes.
– Exercise extreme caution when on slopes.
– Mow across the face of slopes, never up and
down and exercise extreme caution when
changing direction on slopes.
– Always be sure of your footing on slopes.
• Use low throttle settings when engaging the
traction-clutch, especially in high gears. Reduce
speed on slopes and in sharp turns to prevent
overturning or loss of control.
• Stop the blade if the lawn mower has to be tilted for
transportation when crossing surfaces other than
grass and when transporting the lawn mower to and
from the area to be mowed.
• Do not operate the engine in a confined space where
dangerous carbon monoxide fumes can collect.
• Stop the engine
– whenever you leave the lawn mower.
– before refueling.
– before removing the grass bag.
– before making height adjustment unless
adjustment can be made from the operator's
position.
• Stop the engine and disconnect the spark-plug lead.
– before clearing blockages or unclogging chute.
– before checking, cleaning or working on the lawn
mower.
– after striking a foreign object, inspect the lawn
mower for damage and make repairs before
restarting and operating the lawn mower.
– if lawn mower starts to vibrate abnormally (check
immediately).
• Watch out for traffic when crossing or near roadways.
• Lightning can cause severe injury or death. If
lightning is seen or thunder is heard in the area, do
not operate the machine; seek shelter.
Maintenance and Storage
• Keep all nuts, bolts and screws tight to be sure the
equipment is in safe working condition.
• Do not use pressure cleaning equipment on machine.
• Never store the equipment with petrol in the tank
and inside a building where fumes can reach an open
flame or spark.
• Allow the engine to cool before storing in any
enclosure.
• To reduce the fire hazard, keep the engine, silencer,
battery compartment and petrol storage area free of
grass, leaves, or excessive grease.
• Check grass bag components and the discharge
guard frequently and replace with manufacturer's
recommended parts, when necessary.
• Replace worn or damaged parts for safety.
• Replace faulty silencers.
• If the fuel tank has to be drained, do this outdoors.
• Do not change the engine governor settings or
overspeed the engine. Operating an engine at
excessive speed can increase the hazard of personal
injury.
• On multibladed lawn mowers, take care as rotating
one blade may cause others to rotate.
• Be careful during adjustment of the lawn mower to
prevent entrapment of the fingers between moving
blades and fixed parts of the lawn mower.
• To ensure the best performance and safety,
purchase only genuine replacement parts
and accessories. Do not use will fit parts and
accessories; they may cause a safety hazard.
