• Warm up the engine before adjusting the idling
speed.
■ LINE HEAD USAGE
1. Always wear eye protection such as safety
goggles. Never lean over the rotating cutting
head. Rocks or other debris could be thrown into
eyes and face and cause serious personal injury.
2. Keep the debris guard attached in place at all
times when the unit is operated.
TRIMMING GRASS AND WEEDS
• Always remember that the TIP of the line does
cutting. You will achieve better results by not
crowding the line into the cutting area. Allow the unit
to trim at its own pace.
1. Hold the unit so the head is off the ground and is
tilted about 20 degrees toward the sweep direction.
(OP6)
2. You can avoid thrown debris by sweeping from your
left to the right.
3. Use a slow, deliberate action to cut heavy growth.
The rate of cutting motion will depend on the
material being cut. Heavy growth will require slower
action than will light growth.
4. Never swing the unit so hard as you are in danger of
losing your balance or control of the unit.
5. Try to control the cutting motion with the hip rather
