The compatible charger will not charge a faulty
battery pack. The charger will indicate faulty battery
by refusing to light or by displaying problem pack or
charger blink pattern.

NOTE: This could also mean a problem with a
charger.

If the charger indicates a problem, take the charger
and battery pack to be tested at an authorised
service centre.

HOT/COLD PACK DELAY

When the charger detects a battery that is too hot
or too cold, it automatically starts a Hot/Cold Pack
Delay, suspending charging until the battery has
reached an appropriate temperature. The charger
then automatically switches to the pack charging
mode. This feature ensures maximum battery life.

A cold battery pack will charge at about half the
rate of a warm battery pack. The battery pack will
charge at that slower rate throughout the entire
charging cycle and will not return to maximum
charge rate even if the battery warms.

LITHIUM ION BATTERY PACKS ONLY

XR Li-Ion tools are designed with an Electronic
Protection System that will protect the battery
against overloading, overheating or deep discharge.

The tool will automatically turn off if the Electronic
Protection System engages. If this occurs, place the
Li-Ion battery on the charger until it is fully charged.

Important Safety Instructions for All
Battery Packs

When ordering replacement battery packs, be sure
to include catalog number and voltage.

The battery pack is not fully charged out of the
carton. Before using the battery pack and charger,
read the safety instructions below. Then follow

WARNING: Keep the rotating

string roughly parallel with the ground
(tilted no more than 30 degrees). This
trimmer is not an edger. DO NOT TILT
the trimmer so that the string is spinning
near a right angle to the ground. Flying
debris can cause serious injury.

Bump Feed Trimmer Line Feed

Your trimmer uses 2.032 mm diameter nylon line.
Cutting line will wear faster and require more feeding if
the cutting is done along sidewalks or other abrasive
surfaces or heavier weeds are being cut.

As you use the trimmer, the string will get shorter
due to wear. Gently bump the trimmer on the ground
while running at normal speed and the line will feed.

NOTE:

Extending nylon line beyond the 330mm
swath will negatively affect performance, runtime, and
the life of the trimmer due to potential of damaging
motor. Doing so may void the warranty.

Helpful Cutting Tips

• Use the tip of the string to do the cutting; do

not force string head into uncut grass.

• Wire and picket fences cause extra string wear,

even breakage. Stone and brick walls, curbs,
and wood may wear string rapidly.

• Do not allow spool cap to drag on ground or

other surfaces.

• In long growth, cut from the top down and do

not exceed 304.8 mm high.

• Keep trimmer tilted toward the area being cut;

this is the best cutting area.

• The trimmer cuts when passing the unit from

the left to right. This will avoid throwing debris at
the operator.

• Avoid trees and shrubs. Tree bark, wood

moldings, siding, and fence posts can easily be
damaged by the string.
