4 Service
Although the Multishot requires little maintenance if properly cleaned and cared for, certain
components of the unit will need service with regular use. The following is a recommended service
schedule (which will vary with each unit depending on the cleaning, maintenance, and handling by the
owner):

After each 30,000 tag injections the drive roller, idler roller, wire advance lever spring, pull spring,
push wire and needle clamping nut should be inspected for wear, and likely replaced.
 After 50,000 injections the cutter, push rod assembly, and pull spring should be inspected for wear
and likely replaced. This service should be performed at NMT by one of our trained service
technicians.

After 3 years the Counter’s battery should be replaced. This service must be performed at NMT by
one of our trained service technicians.
4.1 Disassembly
1. Remove the tag wire. Release the pressure on the drive roller by moving the spool support arm up
to the “off” position. Grasp the tag wire and pull it out the rear of the Multishot. Remove the tag
supply spool from the spool retainer.
2. Remove the tag supply body from the Multishot body. The tag supply body clips in a slot at the rear
of the Multishot body. To separate the two, remove the alignment bar, being careful to lift it straight
out to avoid binding of the two pins (you may have to initially pry the alignment bar loose with a
thin implement). Once the alignment bar is removed, hold the tag supply body in one hand and the
Multishot body in the other and pull them straight apart so you do not break the feed tube, which
extends into the tag supply body from the Multishot body. The two pieces fit together fairly tightly
so some resistance will be felt.
3. Remove the drive roller assembly:
i. Remove the tag supply body cover and relax the idler roller (off position of the spool
support arm).
ii. Remove the ratchet pull spring, which is attached with two screws to the bottom of the wire
advance lever.
iii. Back out the wire advance lever stop set screw and swing the wire advance lever down
(figure 5).
iv. Loosen the wire guide set screw and slide the wire guide away from the drive roller
assembly.
v. Remove idler shoulder screw and idler roller.
vi. Remove the drive roller shoulder screw and the drive roller assembly will lift out.
4. If you are using the optional head mold holder remove it by loosening the head mold attachment set
screw (figure 7) with the .050” wrench and slide it off the magnetizer assembly.
5. Remove the needle. Use the 1/8” wrench to remove the needle clamping nut (figure 3). Pull the
needle and its nylon ball out of the magnetizer assembly.
