OPERATION
Intended Use
This cordless grass trimmer is designated with rated voltage of 36V D.C. . It is designed only to be
used with battery packs 40LB4001. The fixed line trimmer head installed on this product is intended
to cut smaller types of weed, lawn grass or similar soft vegetation in areas that are hard to reach,
e.g. under bushes, on slopes and edges. It may not be used to work on unusual thick, dry or wet
grass, e.g. pasture grass, or to shred leaves. For safety reasons it is essential to read the entire
instruction manual before first operation and to observe all the instructions therein. This product is
intended for private domestic use only, not for any commercial trade use. It must not be used for
any purposes other than those described.

OPERATION
Trimming
• Attach the trimming head to cut smaller
types of weed, lawn grass or similar soft
vegetation.
• Hold the product firmly with a gap between
the product and your right side.
• Stand upright, do not lean forward and
pay attention to posture. Keep both feet
apart to help retain your balance.
• Hold the trimming head just above the
ground at an angle of approximately 30°
(Fig. 11). Avoid pressing it against the
ground as this can ruin the lawn and damage the product.
• Move the product with a slow regular arc from left to right before moving it back to the starting
position and trimming the next area (Fig. 12).
WARNING
To avoid hazards, remove the battery pack when the user wants to transport the product in
another area to prevent a random start. Failure to heed this warning could result in serious
personal injury.
• Ensure the cutting device remains clean and free from off-cuts that may cause it to jam. Check
regularly. Release the on/off switch and remove the battery pack before checking.
• Trim longer grass in stages; do not cut long grass in one cut (Fig. 13). For the best results, cut
longer grass in steps (Fig. 14).
• Wait until the product has come to a standstill before placing it down.
Tips
• For best results, do not cut wet grass because it tends to stick to the trimming head and guard,
prevents proper discharge of grass trimmings, and could cause you to slip and fall.
