O-Ring Replacement
The Wireless SQP contains two user-replaceable O-Rings in each canister base.
One is located at the base of the thread in the brass canister base.
The other is located on the firing pin.
7.2.1
Canister base O-Ring
The canister base O-Ring should be inspected
every time the canister is changed
. If the rubber appears
worn, frayed or split, the O-Ring should immediately be replaced. It might be necessary to cut the O-ring
out of the canister base using a small blade such as a scalpel.
The replacement O-Ring can simply be pressed into place.
7.2.2
Firing pin O-Ring
It is recommended that the firing pin O-ring is periodically examined for damage. Checking the O-ring every
6-12 canisters is usually appropriate, however this will vary based on the precise operating conditions of
the unit.
In addition, if the Wireless SQP fails to fire correctly, or the response when firing is delayed or ‘sticky’, the
firing pin O-ring must be cleaned or replaced.
