with a new one when required. In case the inside of
the fuel tank is dirty, it can be cleaned by rinsing the
fuel tank with clean petrol.

Use a small soft brush to clean the outside of the
unit. Do not use strong detergents. Household
cleaners that contain aromatic oils such as pine and
lemon and solvents such as kerosene can damage
plastic housing or handle. Wipe off any moisture
with a soft cloth. The tines and fenders can be clea-
ned with water using a garden hose.

allow the unit to cool before storing. Store the unit
only in dry and well ventilated areas.
In case the unit will be stored for an extended time,
use the following storage procedure:
1. Drain all fuel from the fuel tank.
2. Turn the fuel valve to "OFF" position. Remove
the carburetor drain plug (Fig. 24.4) and washer

an appropriate container and wipe off any spilled
fuel. This ensures that all the fuel has been drain-
ed from the carburetor.
