OPERATION
Tips
1. For best results, do not cut wet grass as it tends to stick to the cutting head and guard, prevents proper discharge of grass trimmings and could cause you to slip and fall.
2. Do not allow the spool cover to drag on the ground or other surfaces. 3. Pay special attention when performing work close to trees and bushes. The cutting head
could damage sensitive bark, and damage fence posts. 4. Fold the plant protector out to avoid bringing the cutting device into contact with hard
objects such as walls and curbstones. NOTE: The trimming line will wear faster and require more feeding if the cutting or edging is done along sidewalks or other abrasive surfaces or heavier weeds are being cut.
Replacing the spool
1. Press together both locking device tabs on the spool cover and remove the cover. 2. Remove the old spool from the spool cover 3. Clean out any dirt or grass residue. 4. Put the new spool in the spool housing, thread the line into the hole.
Winding the line
NOTE: Should you wish to wind the line yourself, the instructions are provided below: Self-winding, however, is NOT recommended because if the line is not wound properly it can cause the trimmer’s feed system to malfunction. For this reason, users are strongly urged to purchase the pre-wound spool. 1. Hold the loose ends of the line together with one hand, insert one end of the line into the
groove on the spool. 2. Wind the line following the directional arrows on the spool housing and hook the two
ends into the side grooves.
22

damaged by certain aromatic oils, such as pine and lemon, and by solvents such as kerosene. Moisture can also cause a shock hazard. Wipe off any moisture with a soft dry cloth. 3. Use a small brush or the air discharge of a small vacuum cleaner brush to clean the air vents on the rear housing. STORING THE UNIT 1. Remove the battery pack from the line trimmer when it is not in use. 2. Clean the tool thoroughly before storing it. 3.
