Boom Operation (cont'd)
Boom Tubes
The pulling system comes standard with a 4' and 3' long
boom. The default setup is with the 3' boom between
the puller and elbow, and the 4' tube between the elbow
and nose. This setup can be reversed at the user's dis-
cretion. The boom tubes are held in place by detent pins
with pull rings.
In addition, 3" rigid conduit up to 10' long can be sub-
stituted for either or both of the boom tubes. If 3" rigid
conduit is used, two conditions must be accounted for:
• Because the detents will not hold the conduit in place
in the receptacles, the conduit must be clamped in
place opposite the detent pins using 1/2"-13 screws
(not supplied).
• Because the weight will be too great to use the
crank to raise and lower the boom, manual assist is
required.

Conduit Adapter Couplings
Couplings to attach the puller system to the conduit are
available in 2", 2-1/2", 3", 3-1/2", 4", and 5" sizes.
There are two types: slip-in and screw-on:
• Slip-in couplings are the easiest to use but do intrude
on the ID of the conduit.
• Screw-on couplings do not decrease the effective ID
of the conduit, but take longer to set up.
If longer than standard booms are being used, screw-on
couplings may be necessary to support the boom and
prevent it from falling. The conduit adapter couplings fit
into the same receptacles as the boom tubes and are
retained by the same ring pull detent pins.
