WARNING

• When draining fuel, please be careful not to spill it. If

fuel is spilt, wipe off thoroughly. In addition, please be

sure to close the storage container cap tightly.

IMPORTANT

• If fuel is left in the engine for protracted periods, the

inside of the carburetor may become clogged and

cause engine malfunction (faulty starting and insuffi-

cient output).

• During storage, slightly loosen the cap of the chemi-

cal fluid tank. If screwed too tightly, the gasket may

become distorted.

On completion of all work procedures, when not plan-

ning to use again for a protracted period please carry

out the following pre-storage care, to prevent trouble

caused by time-lapse changes.

11. Storage

1. Clean the chemical fluid tank and nozzle (see page

11).

2. Remove dirt from the sprayer, inspect it for any dam-

age or looseness, and, if any abnormality is found,

correct it thoroughly in preparation for the next time

you use the unit.

3. Drain the fuel tank.

4. Start the engine, and leave it in idling condition until

all the fuel inside the carburetor is spent and the en-

gine comes to a natural stop.

5. Remove the spark plug and put a few drops (1 to 2

cc) of 2-cycle oil inside the engine. After pulling the

starter rope 2 or 3 times, return the spark plugs to

their original position and stop in compressed posi-

tion.

6. After oiling the throttle lever and other metal parts with

anti-corrosive oil, cover the sprayer and store indoors

in a low-humidity location.

10. Maintenance

on the part of the brushcutter.
