FUSE BOLT OPERATION
To achieve top performance from your DM5, it is
important to understand the basic operation of the DM5’s
patented FUSE bolt system.
This design consists of three sleeves threaded together to
capture the only moving part of the system, the bolt.
The FUSE Bolt has four components

Top Hat

Rear Cap
Air is supplied to the bolt at two points. A high-pressure
supply of air is routed to the back of the bolt into the
supply chamber. This air source is responsible for
propelling the ball. Low-pressure air is supplied from the
LPR to the solenoid. From the solenoid, the air is routed
through two small holes to the section of the bolt referred
to as the cylinder.
When the DM5 is aired up, air is transferred by the
solenoid to the front of the cylinder. This air pushes against the bolt sail and the bolt is held in the back position. When the bolt is
held back, the 013 o-ring in the top hat seals around the bolt and contains the air in the supply chamber.
When the marker is fired, the microswitch is pressed, telling the solenoid to switch the flow of air from the front of the cylinder to
the rear of the cylinder. Air that enters the rear of the cylinder will push on the bolt sail, moving the bolt forward. The air in the
front of the cylinder is vented.
As the bolt moves forward, the tapered stem passes through the top hat. Once the bolt stem can no longer seal against the 013
o-ring, the air contained in the supply chamber is released. The air passes through the venturi ports in the bolt and out the front of
the bolt to propel the ball. When the bolt is in the forward position, the inside bolt stem o-ring prevents the flow of air from
continuously flowing through the marker when the bolt is forward. This helps the marker shoot much more efficiently.
NOTE: LOW OR ERRATIC VELOCITY MAY BE DUE TO A LOW BATTERY NOT SUPPLYING
AMPLE ELECTRICAL CURRENT TO THE SOLENOID. IN THIS CASE, CHANGE THE BATTERY.
When servicing your marker:
• Make sure your hopper is removed
from the DM5.
• Make sure there are no paintballs in the
breech of the DM5.
• Always remove the air supply and
relieve all gas pressure in the DM5
before disassembly.
• When using the DM5 in temperatures below
50º, it may be necessary to lube the FUSE
bolt more frequently.
