CLEANING AND STORAGE
3. Drain the oil from the crankcase and add fresh oil. Pull
the starter rope a few times to lubricate the engine.
4. Thoroughly clean the unit and inspect for any loose or
damaged parts. Repair or replace damaged parts and
tighten loose screws, nuts or bolts.
The unit is now ready for storage.
5. Store the trimmer in a dry, well-ventilated area, and
hang with the cutting head up or place the unit flat on
the floor (Fig. 53).
WARNING
Always turn off your trimmer before you clean
or perform any maintenance on it.
Cleaning
Use a small brush to clean off the outside of the trimmer.
Do not use strong detergents on plastic housing or handle.
They can be damaged by household cleaners that contain
aromatic oils such as pine and lemon, and by solvents
such as kerosene. Wipe off any moisture with a soft cloth.
Storage
If the trimmer will be stored for an extended period of
time, use the following storage procedure.
1. Drain all fuel from the fuel tank. Do not use fuel that
has been stored for more than 60 days.
2. Start the engine and allow it to run until it stalls. This
ensures that all fuel has been drained from the carbu-
retor.
