Before you open the case, know that during the reassembly there are multiple points that 
need to align correctly to close the case securely. 
Some of them include:
• Display board sits in groove 
• DC Connector spans both case halves
• Mounting T-nut sits in slot as shown
• Lanyard knot surrounds screw standoff and protrudes through the notch in the case
• Trigger sits in case brackets with wires tucked out of the way
• PCB aligns in a retaining groove
• Battery holders (2) nests in brackets, there is a right and wrong way to insert them
Taking the unit apart is the easy part . . . 
To do this, [A] remove the lens by 
separating the two tabs that hold 
it in place. Put a piece of tape on 
the side of the lens that faces out 
so it can be installed correctly. Slide 
the refl ector [B] and lamp out as  
detailed in the Lamp Replacement 
section of your manual. This will 
expose four screws [C] that must 
be removed so the refl ector hous- 
ing can be removed from the main 
body. There are then four additional 
screws [D1] & [D2] in the case 
halves opposite the input and 
output jacks that must be removed. 
The case halves can now be separated, 
exposing the batteries. They should 
be sent to a recycling center or 
returned to Monarch for disposal.

Placing the left side of the case 
on a roll of tape or other lift 
will prevent the speed knob

the retaining slots when 
aligning all.

Replace the battery.

Fasten both halves using two 2” self tapping 
screws [D] (1053-3328-001) through the body of 
the right half. Do not over tighten screws.
Gently pry apart case halves at the base of the 
handle and insert tee nut [K] (1053-0270-001) 
into slot in left handle.
Slip knotted end of wrist strap [L] (3051-2000-
