Battery Pack Charge Status

Battery pack charge status is indicated by pressing the indicator button on the top of the battery (Fig. 3). Number of bars illuminated indicates
approximate battery pack charge capacity (5 bars: 80-100%; 1 bar: less than 20%).
NOTE: As the battery pack ages, it will normally lose capacity. An older battery pack or one that has been exposed to temperature extremes may show
less than 5 bars after completing a charge cycle (i.e. after a charge cycle, only 4 bars light indicating 60-80% of original capacity is available).
The Lithium-ion battery packs do not require a learn cycle to calibrate or re-calibrate the battery pack charge indicator. However, it may take up to
three complete charge/discharge cycles for the battery to reach its maximum capacity and claimed run times.
CLEANING, INSPECTION, STORAGE AND DISPOSAL
Always follow the hygiene practices established by your employer for the specific contaminants to which the system has been exposed.
Cleaning
Solvents should not be used to clean the battery pack or battery charger. Liquid solvents may chemically weaken the plastic. Use the
following suggested procedures for cleaning:
1. Do not immerse the battery charger into any type of liquid. Wipe the housing of the charger with a dry cloth (pre-moistened cleaning clothes should
also be avoided). Avoid contact with the 4 charging pins; if they become damp, allow to dry before charging.
2. While still on the blower, wipe the housing of the battery pack with a soft cloth moistened with mild cleaning solution.
3. Rinse the battery housing by wiping with a soft cloth moistened with clean water. Wipe dry.
4. Remove battery and wipe down top of battery pack, if needed, with a dry cloth. Avoid contact with the 4 charging pads; if they become damp,
allow to dry before reinstalling on blower or charger.
