options. This adjustability allows the user to best position the light for purposes of
providing clearance around face shields, goggles or other potential obstructions while
still allowing the floodlight to point in a downward direction regardless of the angle of the
brim of the helmet.
INSTALLING BATTERIES INTO THE 4650
To install the included CR-123 Lithium Batteries in the 4650, begin by unscrewing the
screw on the battery compartment door. (Image 1)
Insert both batteries into the battery compartment paying attention to the battery
orientation marked on the back of the battery compartment door. (Image 2)
Re-install the battery compartment screw by pressing the door fully closed and then
tightening the screw until it is hand tight. CAUTION: Do not cross-tread or strip the screw
threads. (Image 3)
Test the operation of the light (see OPERATION below).

ADJUSTING THE ORIENTATION AND/OR ANGLE OF THE MOUNT
The mount on the top of the light is designed to be adjustable in terms of which side
of the helmet it can be mounted to. Additionally, adjustments to the angle of the light can
be made to refine the angle of the beam in relation to the helmet. Out of the packaging,
the mount is set up for attachment to the right side of the helmet. If the light needs to be
mounted to the other side of the helmet or if the angle of the light needs to be adjusted,
use the following steps to make those adjustments:
Using the included 5/32” Allen Wrench, loosen and then remove the Angle Lock
Socket Head Cap Screw and separate the Mount from the rest of the assembly. (Image 4)
If the angle of the light needs to be adjusted, loosen the Angle Adjustment Socket Head
Cap Screw found below the Mount using the 5/32” Allen Wrench, adjust the angle as needed
and then tighten the Angle Adjustment Socket Head Cap Screw completely. (Image 5)
Reinsert the Mount into the rest of the assembly and reinstall the Angle Lock Socket
Head Cap Screw paying close attention to the fact that the Mount is positioned correctly
based on the side of the helmet that the light is to be mounted to. (Image 6)
NOTE: THIS PRODUCT IS NOT DESIGNED TO SWIVEL ONCE THE ANGLE OF
THE LIGHT HAS BEEN SET.

Once the batteries have been installed and the proper orientation and/or angle of
the Mount has been set, the light is ready to be attached to the Fire Helmet or Hard Hat.
The light comes with two 5/16” - 18 x 1/4” Brim Mounting Allen Set Screws pre-installed.
These two Allen Set Screws are designed to be used with the thicker brim found on most
Fire Helmets. (Image 7)
It may be necessary to switch these two Allen Set Screws with the 5/16” - 18 x 3/8”
set if the thickness of the brim of the helmet or Hard Hat makes it impossible to use the
shorter set. (Image 8)
Position the mount over the edge of the brim and tighten the appropriate set of Allen
Set Screws using the included 5/32” Allen Wrench. (Image 9)
Use included mounting shim as necessary to secure the mount to the helmet.
