CHAIN LUBRICATION

9.1

Pickup Body/Suction Hose

Impurities gradually clog the fine pores
of the filter with tiny particles of dirt.
This prevents the oil pump from
supplying sufficient oil to the bar and
chain. In the event of problems with the
oil supply system, first check the oil
tank and the pickup body. Clean the oil
tank if necessary.
Troubleshooting chart - see "Standard
Repairs, Troubleshooting" handbook.
Pickup body
• Unscrew oil filler cap and drain
the oil tank.
Note: Collect chain oil in a clean
container or dispose of properly.
• Use assembly hook (1)
5910 893 8800 to pull the pickup
body out of the oil tank.
Note: Avoid stretching the oil hose.
STIHL 088
• Pull the pickup body out of the oil
suction hose.
- Wash the pickup body in white
spirit and, if possible, blow out with
compressed air.
- Always replace a damaged pickup
body.
- Flush out the oil tank.
Assembly is a reversal of the
disassembly sequence.
Suction hose
- Remove the oil pump - see 9.4.1.
- Use pliers to grip the tab of the oil
hose and pull it out of the bore.
• Pull suction hose and pickup
body out of the crankcase.
• Pull the pickup body (1) off the
suction hose (2).
Reassemble in the reverse
sequence.
- Insert suction hose in bore.
• Use a blunt tool to push the end of
the suction hose into the
crankcase so that the tab locates
it its seat at the bottom right.
- This operation is easier if the bead
of the hose is lubricated with a
little oil.
