Repair instructions

Cleaning and inspection

Carefully check that:

• there are no leaks from the fuel tank

• there are no leaks from the tank filler cap

• the fuel hose is undamaged and free from wear

• the fuel filter is not clogged

• the tank vent is not blocked or leaking

• the vibration damping springs and stops are not

damaged

Replacing the fuel hose

Before replacing the fuel hose, measure the length

of hose between the crankcase and carburettor

and between the tank and crankcase. The correct

hose length between the tank and crankcase is 43

mm (1.69 inches). The correct hose length be-

tween the crankcase and carburettor is 53 mm

(2.09 inches).

Remove the fuel hose from the fuel tank using tool

502 50 83-01. Trim off 5 mm (0.20 inches) from the

mitred end of the hose. Fit the fuel filter and

reinsert the hose in the tank.

NOTE!

Do not use knurled pliers to disconnect or

reconnect the fuel hose. This could

damage the hose.

Replacing the fuel filter

First remove the old fuel filter from the tank unit

using special tool 502 50 83-01.

Pull the fuel hose out of the tank and pull off the

filter.

Fit the new fuel filter and feed the fuel hose back

into position.

NOTE!

Do not use knurled pliers to disconnect or

reconnect the fuel hose. This could

damage the hose and lead to leakage or

fracture.
