EVERY 50 HOURS
More frequently if you notice reduced performance.
INSPECTION
Inspect the entire blower and tubes for damage, including loose or
missing components, and repair as necessary.
SPARK PLUG
Replace the spark plug with a Champion RCJ6Y, gapped to (0.6-
0.7)mm.
FUEL FILTER
Fuel filter
Use a wire hook to extract the
fuel filter from inside the fuel
tank, and then remove and
wash the filter element in clean
fuel. Before reinstalling the filter,
inspect the condition of the fuel
line. If damage or deterioration is
noted, the blower should not be
used until it can be inspected by
a trained service technician.
COOLING SYSTEM
Remove the engine cover (as
described under ‘Spark Arrestor Maintenance), and use a wood or
plastic scraper and a soft brush to remove dirt and debris from the
cylinder fins and crankcase.
Spark Arrestor Maintenance
Hard starting or gradual loss of performance can be caused by
carbon deposits lodged in the spark arrestor screen. For maximum
performance, the spark arrestor screen should be periodically
cleaned as follows:

Remove three self tapping screws and two machine screws from
the engine cover, and then gently move the engine cover aside.
Remove the three spark arrestor retaining screws, and then remove
the spark arrestor cover, screen, gasket, and chamber
Use a plastic scraper or wire brush to remove carbon deposits from
the arrestor screen, chamber, and cover.
Inspect the screen carefully, and replace any screen that has been
perforated, distorted, or is otherwise unserviceable.
Install the chamber, screen, gasket and cover in the reverse order
of disassembly, and then install and securely tighten the three cover
retaining screws.
Install the engine cover, and verify that the fuel line connections are
still tightly in place.
Install the engine cover retaining screws in the reverse order of
removal, and tighten securely.
Install and tighten the spark plug, and reconnect the spark plug
wire.
Drain the fuel if it is to be stored for an extended time.
Important!
Always replace cover screws in the same holes
from which they were removed. Substitution or
incorrect assembly of the engine cover screws can
permanently damage aluminium castings and plastic
components!
Storage for over 30 days
CLEANING
Thoroughly clean the machine exterior.
INSPECTION
Inspect the entire machine and tubes for damage,
including loose or missing components, and repair as necessary.
FUEL
Drain the fuel tank, and then clear the carburettor and lines
by running the machine until it stops from lack of fuel.
LUBRICATION
Remove the spark plug, and then pour
approximately 1/4-oz of oil into the cylinder through the spark plug
hole. Before reinstalling the spark plug, pull the recoil starter 2 or 3
times to distribute the oil over the cylinder walls.
AIR CLEANER
Remove, clean, and reinstall the filter element as
described under “daily maintenance.”
STORAGE
Store the machine in a clean, dry, dust free environment.
Warning!
Never store the machine with any fuel remaining in
the tank, fuel lines, or carburettor! Your warranty does
not include coverage for damage caused by ‘stale’ or
contaminated fuels!
