Fuel Gauge Battery Packs (Fig. 6)
Some DeWALT battery packs include
6A
FIG. 6
 
a fuel gauge which consists of three 
green LED lights that indicate the 
level of charge remaining in the 
battery pack. 
To actuate the fuel gauge, press and 
hold the fuel gauge button (6A). A 
combination of the three green LED 
lights will illuminate designating the level of charge left. When the level 
of charge in the battery is below the usable limit, the fuel gauge will not 
illuminate and the battery will need to be recharged.
NOTE: The fuel gauge is only an indication of the charge left on the battery 
pack. It does not indicate appliance functionality and is subject to variation 
based on product components, temperature and end-user application.
For more information regarding fuel gauge battery packs, please call

This string trimmer gives you the choice to operate at a more efficient 
speed to extend the runtime for larger jobs, or accelerate the trimmer 
speed for high-performance cutting. 
WARNING: 
Remove the battery before making any 
assembly, adjustments, or changing accessories. Such preventive safety 
measures reduce the risk of starting the 
TRIMMER
 accidentally.
CAUTION: Before you begin trimming, only use the 
appropriate type of cutting line. 
CAUTION: Inspect area to be trimmed and remove 
any wire, cord, or string-like objects which could become entangled in 
the rotating line or spool. Be particularly careful to avoid any wire which 
might be bent outwardly into the path of the appliance, such as barbs 
at the base of a chain link fence.
