front of the mount. Insert the new light by placing the back end of the
light through the mount and pull tight to ensure it is snug. Replace the
protective lens cap and re-insert the four screws to fasten the cap to the
mount. NOTE: Install protective lens prior to use in the field!

The Larson Electronics BLG-LED-4REX-GRN Explosion Proof LED Blasting Gun Light has a 4 watt LED that produces
130 lumens of intense LED illumination and is designed for extreme durability in media blasting applications. This
powerful green LED light is designed to be mounted to any standard blasting gun and is powered by rechargeable
batteries so no cords or transformers are necessary. This light will run for 4 hours at full power on a single charge. A
specially designed mounting system and quick change protective shield allows operators to use this unit as a blasting
gun mounted light source that will stand up to abusive use.
The protective lens is a simple slide in, slide out configuration. Aslot in the bottom of the lens holder allows particles to
clear when performing lens changes.

CHARGING
Fully charge your flashlight before first use. Several charge/discharge cycles may be
needed to achieve full battery capacity. The flashlight may be stored in the charger
continuously when not in use. To charge the flashlight, first turn it off and insert it into
the charger. The triangular plate on the head fits into a mating recess in the charger.
With the plate toward the charger, slip the barrel of the light between the charger
arms and pull downward until it locks into place. The red LED on the charger housing
must light to insure that the battery is being charged. Keep the flashlight and charger
contacts clean at all times. Poor contact can cause charger malfunctions. An abrasive
pencil eraser works well to clean the contacts. It should be fully charged in 12 hours.
Red LED remains on as long as flashlight is in the charger.
Observe the red LED:
•If the LED does not blink rapidly and continuously, indicating a full charge, within
3.25 hours check the contacts and the charger’s power supply wiring. If no
obvious problem is found, return the system for service.
•Proper function of the fast charge circuitry can be determined by inserting a
flashlight into the charger for at least 5 minutes. Turn the flashlight “on” and the
red LED should switch to blink mode within 5 minutes. The fast charger is
equipped with circuitry to prevent fast charging in temperature extremes (below
40° F and above 115°)
•When temperature is within the acceptable range fast charging will begin.
BATTERY REPLACEMENT
Simply unscrew the tail cap and slide the battery from the flashlight. Replace the battery inserting the contact
end firstand reattach the tail cap.
