Installation
The process of installing the INFERNO HPA
engine can vary greatly depending on your replica.
To make it easier, we have a
variety of videos available online
specific to a common gun plat-
forms.
Please scan the QR code or
visit www.wolverineairsoft.com/
documentation.
Nozzle Replacement
Our standard INFERNO HPA
kits come standard nozzles that
fit most replicas. However, your
replica may require a different
nozzle to be installed. (Please
see our Compatibility Guide at
www.wolverineairsoft.com/com-
patibility).
You can easily change the nozzle by first remov-
ing the cylinder and then the baffle. Pay close at-
tention to the placement of the O-rings and the
spring when re-assembling and ensure the parts
are properly lubricated. Please see the Mainte-
nance chapter for more detailed instructions.

Tuning
Tuning refers to the process of electronically
adjusting the engine’s dwell for maximum perfor-
mance and efficient air usage.
Dwell is a measurement of the length of time
that the solenoid valve is opened, allowing air
to flow from the air tank to propel the BB. For
maximum efficiency the dwell time must be set
precisely to provide just enough air to carry the
BB to the end of the barrel. If the dwell time is
too high, air will be wasted out the end of the
barrel with each shot. If the dwell time is too low,
velocity will be inconsistent, causing inaccuracy.
Please refer to the Spartan
Electronics or Premium FCU
owner’s manuals at
www.wolverineairsoft.com/
documentation for detailed tun-
ing instructions.

Begin by disassembling your
Inferno unit by unscrewing the
two halves counterclockwise.
Next, disassemble the cylinder
assembly by pushing the nozzle
towards the back of the cylin-
der. The two-piece baffle may
come apart.
Pay close attention to the 1mm
x 10.5mm O-ring around the
poppet and do not lose it. You
will need it for reassembly.
Maintenance
Regular maintenance on the INFERNO HPA en-
gine should be performed every 25-50k rounds
depending on the conditions it is being used in.
The dustier and dirtier the conditions, the more
frequently it should be serviced.
Items needed:
- O-ring compatible lubricant. (We recommend
TechT GunSav)

Next slide the baffle off of the
nozzle/poppet assembly and pull
out the spring.
Lubricate the 1.5mm x 16mm
O-ring located below the
threads and the 1mm x 13mm
O-ring located above the
threads.
If for some reason the two
piece baffle comes part you
can simply slide the two halves
back together. Make sure that
the 1mm x 13mm O-ring is still
in place on the lower half of the
baffle when you do so.
Your Inferno is ready to re-
assemble. Begin by sliding the
poppet and nozzle assembly into
the baffle. Then install the 1mm
x 10.5mm O-ring around the
nozzle. Then slide the baffle and
nozzle back into the cylinder.
Lubricate the 1mm x 13mm
O-ring around the poppet base.
Note: the nozzle and poppet as-
sembly does not come apart.

Next, place the spring into the
back of the nozzle as indicated.
Finally, align the spring with the
cup on the valve body and push
the valve body into the cylinder.
Screw the two halves of the
unit back together clockwise.
For solenoid maintenance, please refer to our
separate Solenoid Maintenance Guide available at
www.wolverineairsoft.com/documentation.

Symptom Possible Solution
Gun always fires in semi
regardless of selector
switch position
The selector plate is not engaging the se-
lector switch and will need material added
to permit proper operation. Contact WA
or a qualified technician for assistance.
-The burst setting is set to semi-auto
Gun always fires in burst
regardless of selector
position
-The selector plate is always engaging
the selector switch and will need material
removed to permit proper operation. Con-
tact WA or qualified tech for assistance
In burst the gun fires one
BB and then continues to
cycle/blow air down the
barrel but no bbs fire
-Rate of Fire (ROF) is set too high. Reduce
ROF to allow the action time to cycle and
load bbs.
Inconsistent/Low velocity -Dwell is set too low, -Damaged O-rings
-Air nozzle is too short and not providing
adequate seal at the hop up bucking. Con-
tact WA or qualified tech for help.
The valve cycles/releas-
es burst of air but no
bbs fire
-Non-feeding magazine
-Air nozzle is too long
Contact WA or qualified technician for
assistance
Nothing happens when
trigger is pulled
-Dead battery
-Trigger is not properly engaging the
trigger switch. Open gearbox and manually
press the trigger switch to see if solenoid
fires. If not, contact WA or qualified tech
for help.
Poor air efficiency -Dwell is set too high, -Damaged O-rings
-Air nozzle is too short and not sealing at
the bucking
-System air leak, check for audible signs of
leak point.
