FUSE™ BOLT OPERATION

To achieve top performance from your M2, it is important to understand the basic

operation of the M2’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 six

components:

1 Cylinder

2 Bolt Sail

3 Bolt

4 Top Hat

5 Manifold

6 Tool-less Back 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 shot 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 M2 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 014 O-ring in the top hat seals around the bolt and

contains the air in the shot chamber. When the marker is fired, the micro switch is

pressed, activating the solenoid and switching the flow of air from the front of the cylinder

to the rear of the cylinder. Air that enters the rear of the cylinder pushes on the bolt sail,

moving the bolt forward. The air in the front of the cylinder is vented out of the marker.

As the bolt moves forward, the tapered shelf passes through the top hat. Once the bolt’s

shelf can no longer seal against the 014 O-ring, the air contained in the shot 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,

CHARGE THE BATTERY.

BOLT ASSEMBLY AND MAINTENANCE

WHEN SERVICING YOUR MARKER:

• MAKE SURE YOUR HOPPER IS REMOVED FROM THE M2.

• MAKE SURE THERE ARE NO PAINTBALLS IN THE BREACH OF THE M2.

• ALWAYS REMOVE THE AIR SUPPLY AND RELIEVE ALL GAS PRESSURE IN THE

M2 BEFORE DISASSEMBLY.

• WHEN USING THE MARKER IN TEMPERATURES BELOW 50° FAHRENHEIT IT MAY

BE NECESSARY TO LUBE THE FUSE™ BOLT MORE FREQUENTLY.

• THE M2 CAN HOLD A SMALL RESIDUAL CHARGE OF GAS, AFTER THE AIR

SUPPLY HAS BEEN REMOVED. ALWAYS DISCHARGE THE MARKER IN A SAFE

DIRECTION TO RELIEVE THIS RESIDUAL GAS PRESSURE.
