TRIMMER/EDGER MODEL ST275
RECOMMENDED ACTIONS
This may occur when the trimmer/edger is
run continuously or exposed to high ambient
temperatures. Allow the battery pack to reach the
acceptable temperature range before charging.
See "Battery pack and charger".
Inspect the contacts on both the battery pack and
the charger. Clean as described in "Maintenance
and cleaning", then reinsert into the charger and
make sure it is fully seated.
All batteries have a limited life. If the battery pack
is more than two years old or has been recharged
frequently, it may be time to replace it. Replace only
with the battery pack specified for this trimmer/
edger.
Have the function checked at an approved service
location.
Follow guidelines for the operation you are
performing. See "Trimming" or "Edging".
Apply less pressure to the throttle trigger.
See "Correcting grass bind".
See "Battery pack and charger".
1. Make sure the charger cord is connected to both
the charger and the electrical outlet.
2. Make sure the charger is receiving the correct
voltage.
3. Try charging another battery pack designed for
this charger.
If this does not correct the problem, have the
function checked at an approved service location.
