Wireless SQP User Manual
29
To access the firing pin O-ring:
1.
Remove the rubber plug from the base of the Wireless SQP.
2.
Remove the thrust rod from the solenoid by sliding it out the base of the unit, through the un-
plugged hole.
3.
Remove the spring from the firing mechanism.
4.
The firing pin can now be removed from the bottom of the brass base.
If the O-ring appears worn, frayed or split it must be replaced. The O-ring should be cut off the firing pin
with a sharp blade such as a scalpel, taking care not to scratch the firing pin itself. A new O-ring should be
eased into place from the top end of the pin. Do not push the O-ring over the thread on the firing pin.
A chemically inert lubricant such as general purpose silicone grease must be applied to the O-ring before
the pin is replaced. A thin layer should be applied to the O-ring, and any excess should be wiped away.
When the O-ring has been replaced, re-install the firing pin.
Please note:
Under no condition should the firing pin be pushed up out of the top if the canister
base. This will force the firing pin O-ring across the canister base’s side opening, damaging the
rubber and compromising the seal created.
Please note:
If the WSQP is to be operated exclusively with coloured fluid (Red or Green) the pin
O-ring must be inspected after at most 12 canisters per base.
Warning:
Failure to apply lubricant to the O-ring may result in the pin sticking. This can lead to a
delay in firing or shutting off, non-ignition conditions, and reduce the life of the O-ring.
7.3
Cleaning of spark electrode
The spark electrode inside the flue can get dirt and deposit build-up on it. This build-up can be conductive,
and hence affect the spark, which in turn could affect ignition and potentially cause non-ignition events, if
the spark detection circuitry fails to disable the machine prior to arming.
The electrode should be cleaned after every use (allow machine to cool down first).
To clean the spark electrode turn machine off (no power supply connected, E-STOP removed, both battery
isolation switch and key switch in OFF positions), and wipe down electrode with a cloth or tooth brush to
clean any deposits off. Thin flexible wire brush can be used for more persistent residue.
Be careful not to exert significant twisting torque or force along the electrodes, as this could damage the
spark ignitor.
7.4
Preserving battery lifetime
Battery should be fully discharged (11.8V rested) and charged again to full (12.8V rested) every three to six
months, when machine is in use.
Battery should be charged at least once every six months, when machine not in use (in storage).
