9. CHAIN LUBRICATION<br />
9.1 Suction Hose/Pickup Body<br />
Impurities gradually clog the fine<br />
pores of the filter with tiny particles of<br />
dirt. This prevents the oil pump from<br />
supplying sufficient oil to the bar and<br />
chain. In the event of problems with<br />
the oil supply system, first check the<br />
oil tank and the pickup body. Clean<br />
the oil tank if necessary.<br />
Troubleshooting chart - see 2.5.<br />
• Wash the pickup body in white<br />
spirit and, if possible, blow out<br />
with compressed air.<br />
Note: If pickup body is damaged,<br />
fit a new one.<br />
• Remove oil tank filler cap.<br />
Flush out the oil tank.<br />
• Remove the chain sprocket –<br />
see 3.3.<br />
• Push suction hose off the nipple<br />
on the oil pump.<br />
• Take out the screws (1).<br />
• Remove the cover (2).<br />
• Pry the hose flange out of the<br />
crankcase.<br />
• Remove the suction hose with<br />
pickup body.<br />
• Insert suction hose, pickup body<br />
first, in the crankcase.<br />
• Pull the worm off the crankshaft<br />
stub.<br />
• Pull the pickup body out of the<br />
suction hose.<br />
Note: Coat flange on hose with a<br />
little oil to simplify fitting.<br />
Assembly is a reversal of the<br />
disassembly sequence.<br />
