The
caution should be exercised when replacing the lamp.

To

change the lamp it is necessary only to remove the Front lens, which is held in place by the rubber
bumper. Pry the rubber bumper off the end of the unit. The reflector is held in place by the front lens
and will come loose, but is not necessary to remove the reflector. Hold the lamp with a cloth between
your forefinger and thumb and rock it back and forth gently while pulling out. Do not attempt to
rotate the lamp. The lamp is socketed and will come out easily when pulled.

Battery Disposal

Prior to disposing of the Battery Pack, the user must remove the sealed lead acid battery. To do
this, remove the four screws on the under side of the Battery Pack and separate the case halves,
exposing the battery. Remove the cables from the battery and place tape over the battery
terminals to prevent them from shorting. The battery should be sent to a recycling center or
returned to the factory. The rest of the parts may now be disposed of.
