• Generator – troubleshooting
1
Remove the cylinder cover and cover from the
front hand grip. Disconnect the black lead from the
generator and connect a multimeter between it and
a clean area on the cylinder. The multimeter should
show a resistance of 0.9–1.3 ohm. If higher or
lower, replace the generator, see "Replacing the
generator".
2
Reconnect the lead and refit the hand grip cover
and cylinder cover.
• Switch – troubleshooting
1
Carefully free the switch and frame from the front
hand grip using a screwdriver.
2
Disconnect the leads from the switch and connect
a multimeter to it. The meter should read over
1000 ohm when the switch is in the "0" position.
The meter should read no higher than 0.1 ohm with
the switch in the "1" position. Replace the meter if
the readings are outside these limits.
Rear hand grip heater not working
• Rear hand grip heater – troubleshooting
1
Remove the cylinder cover, air filter and cover from
the rear hand grip.
2
Remove the throttle pushrod, see "Carburettor –
removal".
3
Remove the bolt from the plate at the base of the
carburettor to release the lead for the heater
element.
4
Disconnect the red lead from the heater element
and connect a multimeter between it and the black
earth lead that is bolted to the bottom of the
carburettor on the clutch side of the saw. The meter
should read 0.7–1.2 ohm. If the reading is higher
replace the heater element.
Heater element and rear hand grip –
removal
1
Remove the cylinder cover, hand grip cover, hand
grip and right-hand stop.
Then remove:
• throttle lock, throttle trigger and return spring,
see "Throttle lock, throttle trigger and return
spring - removal"
• fuel hose and throttle pushrod from the carburettor
Unbolt the rear tank mounting from the crankcase,
i.e. the rear vibration damping spring, and both
stops. Lower the tank as far as it will go to allow
access to the heater lead where it is secured to the
tank.
Refit:
• fuel tank with both stops (3-4Nm) and the rear
vibration damping spring (4-5Nm)
• throttle lock, throttle trigger and return spring,
see "Throttle lock, throttle trigger and return
spring - removal".
• fuel hose and throttle pushrod to the carburettor
(check that the hose is not trapped between the
tank and crankcase, measurement 43 mm (1.69
inches))
• hand grip cover, air filter and cylinder cover
Heater element and rear hand grip –
removal
1
Screw the heater element into place using the two
screws and feed the leads through the rear hand
grip. Secure the red lead in the clip on the tank and
connect it. Feed the black lead through crankcase
and secure/earth it to the base of the carburettor
using the bolt at the front on the clutch side of the
saw. Tighten to a torque of 3–4 Nm.
2
Refit:
• fuel tank with both stops (3-4Nm) and the rear
vibration damping spring (4-5Nm)
• throttle lock, throttle trigger and return spring,
see "Throttle lock, throttle trigger and return
spring - removal".
• fuel hose and throttle pushrod to the carburettor
(check that the hose is not trapped between the
