10Section 4: Operation
WARNING
THROWN OBJECT HAZARD
•Objects such as rocks, pebbles, and small debris will be thrown violently by the cutting head, resulting in sig- nificant hazard to eyes and exposed body parts.
•Always wear
•Keep children, pets and bystanders 50 feet away from machine while operating.
•Be alert to hidden obstacles.
Failure to comply could result in injury or property damage.
Vary Throttle Setting
For Conditions
The majority of trimming and mowing jobs will yield the best results if the engine throttle is set at the fastest engine speed.
Less demanding jobs (and projects that require very precise cutting) may yield better results if the engine speed is backed off somewhat. (For example, damage to trees and shrubs can be avoided by reducing the engine speed; using the lighter .130" diameter line; and by keeping a safe distance away.)
Again, once you begin a particular job and get a “feel” for the conditions, you will be able to make adjustments for the best possible results.
Use Correct Walking Speed
Use a walking speed that is suitable for the mowing conditions. You’ll get better results at slower walking speeds if the growth is tall or lush. Shorter grass or less dense growth can be cut at faster walking speeds.
Trim When Wet or Dry
Grass and most other materials are most efficiently trimmed when dry. But, the unit will do a fine job even with damp or wet materials. When conditions are moist or damp, be sure to clean debris off the machine regularly to keep cutting efficiency high. And watch your footing!
Do Not Let the Trimmer
Lines Become Too Short
Once the trimmer lines are worn to less than 1/2 their original length, trimming jobs begin to take far longer than they should.
As a general guideline, once the line length becomes half of its original length, it’s time to change to new lines.
Use Extreme Caution on Slopes
When operating on sloping ground, use extreme caution and common sense to avoid possible injury or property damage.
Do not mow on excessively steep slopes! Avoid slopes if greater than 150 or wher- ever footing is unsure. If a slope is diffi- cult to stand on, it is probably too steep to trim or mow. In this case, it may be wiser to establish a permanent ground cover on this area.
Do not trim on slopes when the ground is slippery. Trim across the face of a slope, not up and down. Slow down and exer- cise caution when changing direction on slopes.
Keep the Mowed Side to Your Right as You Move Ahead
The unit feeds cut materials to the right side. Stay on the right side of unmowed growth as you move along.
Clean the Unit Frequently
Clean under the mower deck frequently to remove any grass buildup. Also clean around the muffler and on top of engine. See the cleaning instructions in Section 5.
