Fuel System - Husqvarna K970 II Rescue Operator's Manual

• Loosen the bolts holding the spring cassette.
• Remove the recoil spring by turning the starter over
and loosen the hooks, with the help of a screwdriver.
The hooks hold the return spring assembly on the
starter.

and tension the recoil spring.
Fitting the starter
• To fit the starter, first pull out the starter cord and place
the starter in position against the crankcase. Then
slowly release the starter cord so that the pulley
engages with the pawls.
• Tighten the screws.
MAINTENANCE

Fuel system

General
• Check that the fuel cap and its seal are not damaged.
• Check the fuel hose. Replace when damaged.
Fuel filter
• The fuel filter sits inside the fuel tank.
• The fuel tank must be protected from contamination
when filling. This reduces the risk of operating
disturbances caused by blockage of the fuel filter
located inside the tank.
• The filter cannot be cleaned but must be replaced with
a new filter when it is clogged. The filter should be
changed at least once per year.
Air filter
The air filter only needs to be checked if the engine drops
in power.
• Loosen the screws. Remove the air filter cover.
• Check the air filter and replace if necessary.
Replacing the air filter
NOTICE! The air filter must not be cleaned or blown
clean with compressed air. This will damage the filter.
• Remove the screw.
• Replace the air filter.
Drive gear, clutch
• Check the clutch centre, drive gear and clutch spring
for wear.
