MAINTENANCE
WARNING
Use only original manufacturer's replacement
parts, accessories and attachments. Failure to
do so can cause possible injury, poor perfor-
mance and may void your warranty.
■ You may make adjustments and repairs described
here. For other repairs, have the product serviced by
an authorized service agent.
■ Consequences of improper maintenance may
include excess carbon deposits resulting in loss of
performance and discharge of black lubricanty residue
dripping from the muffler.
■ Make sure all guards, straps, deflectors and handles
are properly and securely attached to avoid the risk of
personal injury.
■ The cutting attachment must not work in idle mode.
If this requirement is not satisfied, the clutch has to be
adjusted or the machine needs an urgent maintenance
by a qualified technician.
■ Neglected or poorly conducted maintenance may
create additional hazards. Do not attempt to repair
or maintain the product if you are not qualified to do
so. If in doubt, return to a Ryobi service centre for
professional assistance.
LINE REPLACEMENT (Fig. 8)
■ Ensure the unit is in the off position
■ Remove the spark plug lead to prevent accidental
starting.
■ Use a 2.4 mm diameter monofilament string.
■ Cut one piece of string approximately 6m in length
■ Rotate the knob on the bump head until the line on the
knob aligns with the arrows on top of the bump head.
■ Insert one end of the string into the eyelet located on
the side of the bump head and push until the string
comes out through the eyelet on the other side.
Continue to push the string through the bump head
until the middle section of the string is inside the bump
head and string outside the bump head is evenly
divided on each side.
■ Rotate the knob on the bump head counterclockwise
to wind the string
■ Wind the string until approximately 20 cm remains
protruding from the bump head.
CLEANING THE EXHAUST PORT AND MUFFLER
Depending on the type of fuel used, the type and amount
of lubricant used, and/or your operating conditions,
the exhaust port and muffler may become blocked with
carbon deposits. If you notice a power loss with your petrol
powered tool, a qualified service technician will need to
remove these deposits to restore performance.
SPARK ARRESTOR
The spark arrestor must be cleaned or replaced every
25 hours to ensure proper performance of
your product. Spark arrestors may be in different locations
depending on the model purchased. Please contact your
nearest service dealer for the location of the spark arrestor
for your model.
CLEANING THE AIR FILTER (Fig. 9)
For proper performance and longer life, keep the air filter
clean.
■ Ensure the unit is in the off position.

■ Remove the air filter and clean it with warm soapy
water.
■ Rinse, and let the air filter dry completely.
■ Work two drops of lubricant into the air filter.
■ Replace the air filter (fits only one way).
■ Replace the air filter cover.
NOTE:
The air filter should be replaced annually for the
best performance.
FUEL CAP
WARNING
A leaking fuel cap is a fire hazard and must be
replaced immediately.
The fuel cap contains a non-serviceable filter and a

Replace fuel cap if required.
