3.Never clean, or make adjustments or repairs with the engine running. Discon- nect the spark plug wire and keep the wire away from the plug to prevent accidental starting. Remove ignition key on electric start models.

4.Keep all nuts and bolts tight, espe- cially the trimmer head attachment bolts, and keep equipment in good condition. Check mounting hardware on trimmer head every time you change trimmer line and prior to each use.

5.Never tamper with safety devices. Check their proper operation regularly.

6.To reduce fire hazard, keep machine free of grass, leaves or other debris build- up. Clean up oil or fuel spills. Let machine cool before storing.

7.After striking an object, stop the engine and disconnect the spark plug wire. Inspect the machine and repair, if neces- sary, before restarting.

8.Never make adjustments or repairs while engine is running.

9.Components subject to wear, damage and deterioration could expose moving parts or allow objects to be thrown. Fre- quently check components and replace with factory recommended parts, when necessary. Regularly inspect the trimmer head and debris shield. Make sure they are not bent, damaged or loose.

10.Only use eighteen-inch long, .130" or

.155" diameter trimmer line. Never use other lengths, diameters or material as trimmer line.

11.Trimmer line moves at high speed and can cut. Always stop the

engine and let all moving parts stop before replacing the trimmer lines. Let the engine cool.

12.Do not change the engine governor setting or overspeed the engine. The gov- ernor controls the maximum safe operat- ing speed and protects the engine and all moving parts from damage caused by overspeed. Authorized service shall be sought if a problem exists.

13.Do not touch engine parts which may be hot from operation. Allow parts to cool completely before inspecting, cleaning or repairing the unit.

14.Maintain or replace safety and instruc- tional decals. Refer to the Parts List for replacement decal information.

15.Use only original-equipment replace- ment parts. Parts manufactured by others could present safety hazards and affect performance even though they may fit on this machine.

16.Remember—the end of the season is a good time to inspect equipment prior to storage.

17.To guard against engine overheating, always keep the engine debris guard mounted and clean.

18.For units with electric start:

a)Batteries produce explosive gases. Keep sparks, flame, cigarettes, etc., away. Ventilate the area when charging the battery. Do not charge the battery in an airtight space.

b)Do not use a battery charger other than the one provided with the unit.

c)The battery contains toxic materi- als. Do not damage the battery case. If the case is broken or dam- aged, avoid contact with the battery contents.

d)Properly dispose of a damaged or worn battery. Check with local authorities for proper disposal.

e)Do not short circuit the battery. Severe burns and fire can result.
