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 first stage regulator
and relieve all residual gas pressure from
the DM5 before disassembly.
• The DM5 can hold a small residual charge
of gas, typically 2 shots, with the first stage
regulator removed. Always discharge the
marker in a safe direction to relieve this
residual gas pressure.

ON/OFF: USAGE AND CHANGING O-RINGS
The On/Off knob is located under the barrel in the front of the DM5
(see figure 2)
. Using the on/off is simple. To turn the
gas off, turn the knob so that is is facing sideways. If you had gas inside the marker, it will bleed out. To turn the gas on,
turn the knob so that it faces vertically.
The ON/OFF has three o-rings

In case of a leak from the on/off, it is easy to service:
1
Take the frame off the marker.
2
Unscrew set screw holding on/off in place (screw just in front of the front frame screw).
3
Pull out on/off, change damaged o-ring(s).
4
Lube with grease.
5
Push back in.
6
Screw in set screw.
7
Put frame back on.
8
Gas up and test.
MAINTENANCE
The on/off needs very little maintenance. To help prevent o-ring failure and leaks, grease the on/off every four months
or sooner, depending on the severity of playing conditions. Cold, wet weather will shorten the effective life of the
grease. Heavy dust or fine sand can infiltrate the on/off and prevent it from moving smoothly and/or cut the o-rings.
NOTE: Air may still be present in the LPR and solenoid after the air has been vented from the marker by the on/off. Be
sure all air has been vented by discharging the marker in a safe direction. If servicing the marker, removal of the bolt will
also allow any trapped air to escape.
