USING THE LINE TRIMMER
Clear the area to be cut before each use. Remove all objects, such as rocks,
broken glass, nails, wire, or lien that can be thrown or become entangled in
the cutting attachment. Clear the area of children, bystanders, and pets. At a
minimum, keep all children, bystanders, and pets at least 15 m away; there
still may be a risk to bystanders from thrown objects. Bystanders should be
encouraged to wear eye protection. If you are approached, stop the motor and
cutting attachment immediately.
Before each use check for damaged/worn parts
Check the trimmer head, guard, shoulder strap, shoulder strap loop, and front
handle. Replace any parts that are cracked, warped, bent, or damaged in any
way. The line-cutting blade on the edge of the guard can dull over time. It is
recommended that you periodically sharpen it with a file or replace it with a
new blade.
WARNING:
Always wear gloves when mounting or replacing the guard or when sharpening or
replacing the line-cutting blade. Note the location of the blade on the guard
and protect your hands from injury.
After each use, clean the trimmer.
ADJUSTING THE CUTTING LINE LENGTH
The Line-IQ feeding trimmer head is equipped with advanced technology.
If either end of the cutting line wears less than 18 cm during trimming, the trimmer head will release the cutting line automatically, and the extra part of the cutting line will be cut off by the line-cutting blade (Fig. K).
- NOTICE: No need to tap the trimmer head to release the cutting line. If you feel a slight tremor of the trimmer head when trimming the grass, it is the cutting line being automatically released.
- WARNING: Do not remove or alter the line-cutting blade assembly. Excessive line length will cause the motor to overheat and may result in serious personal injury.
LINE REPLACEMENT
NOTICE:
Always use the recommended nylon cutting line with a diameter of 2.4 mm.
Using a line other than that specified may cause the tool to overheat or become damaged.
WARNING:
Never use metal-reinforced lines, wires, rope, etc. These can break off and
become dangerous projectiles.
The line trimmer is equipped with an advanced POWERLOADTM system. The cutting line can be wound onto the spool simply by pressing a single button. Loading a full spool can usually be completed in 12 seconds. Avoid repeated operation of the winding system in rapid succession to reduce the possibility of motor damage.
- Remove the battery pack.
- Cut one piece of cutting line 4 m long.
- Insert the line into the eyelet and push the line until the end of the line comes out of the opposite eyelet (Fig. L1).
L1-1| Cutting line| L1-2| Eyelet
---|---|---|---
NOTICE: It is not necessary to align the eyelets in order to insert the cutting line. If the line cannot be inserted into the eyelet, mount the battery pack onto the trimmer, then press the POWERLOAD button briefly to reset the winding mechanism.
- Remove the battery pack if it has been mounted onto the trimmer in step 3.
- Pull the line from the other side until equal lengths of the line appear on both sides of the trimmer head (Fig. L2).
- Install the battery pack onto the line trimmer.
- Press and hold the POWERLOAD button to start the line-winding motor. The line will be wound into the trimmer’s head continuously.
- Watch the remaining line length carefully. Prepare to release the button as soon as approximately 22 cm of the line is left on each side. Briefly press the line loading button to adjust the length until 18 cm of the line is showing on each side (Fig. L3).
NOTICE:
In case the line is pulled into the trimmer head by accident, open the head
and pull the cutting line out from the spool. Follow the section “RELOADING
THE CUTTING LINE” in this manual to reload the line.
RELOADING THE CUTTING LINE
