Cleaning The Air Filter - Ryobi RY5020 Manuel D'utilisation

WARNING:
Although the guide bar comes with a SAFE-
T-TIP™ antikickback device already installed,
check the tightness of the mounting screw
before each use.
Use the following instructions to tighten the mount-
ing screw of the nose guard. These are specially
hardened screws. If you cannot install the screw
tightly, replace both the screw and the SAFE-T-
TIP™ before further operation.
NOTE: Do not replace the screw with an ordinary
screw. Use only identical replacement parts from
the manufacturer when replacing parts.
In addition to preventing chain contact with solid
objects at the nose of the bar, the SAFE-T-TIP™ also
helps keep the chain away from abrasive surfaces,
such as the ground. Keep it on the right hand side
of the bar where it will be between the chain and
the ground during flush with ground cutting.
The mounting screw requires a 5/16 in. wrench (or
adjustable wrench) to achieve the recommended
torque of 35 to 45 in.lb. A torque within this range
can be achieved by using the following method.
 Tighten the screw with wrench until snug.
 From the snug position, tighten the screw an
additional 3/4 of a turn using a wrench.

CLEANING THE AIR FILTER

See Figures 59 - 62.
 Push down on the knob on top of the air filter
cover and rotate counterclockwise to unlock.
Lift cover straight up to remove; set aside.
 Before removing the air filter from the carbure-
tor, blow or brush as much loose dirt and saw-
dust from around the carburetor and chamber
as possible.
NOTE: Make sure to pull the choke rod out to
keep the carburetor from being contaminated.
 Using the combination wrench provided or a flat
blade screwdriver, remove the screw securing
the air filter.
 Position a flat screwdriver between the tabs and
twist to release from the air filter base.
 Lift the air filter off the air filter base.
MAINTENANCE
Choose one of the following cleaning options:
 To lightly clean, tap the filter against a smooth,
flat surface to dislodge most saw dust and dirt
particles.
 After every 5 hours of operation, clean in warm
soapy water, rinse, and let dry completely.
Replace with a new filter after every 25 hours
of use.
NOTE: An alternate method is to clean the filter
with compressed air. Always wear eye protec-
tion to avoid eye injury.
