D7x11 Series II Navigator Directional Drill Overview 30-21
REAMER INSTALLATION
Swivel
The reamer must be equipped with a rear swivel to prevent trailed rod or product from turning while reaming. If
reamer does not have a built-in swivel, an external swivel must be installed. Refer to the Operation section,
“Swivel Use,” page 50-25, for information on swivel installation and safety.
Reamer Carrier - Intended Use
Vermeer reamer carriers are used to lift heavier reamers weighing more than 50 lb (23 kg). The carrier provides
an easy method of installing or removing reamers at the exit site while the machine is locked out. While holding
the reamer with the carrier, the reamer can be turned by hand without rotating the drill string.
Reamer Carrier Styles
DANGER: Serious injury or death will result if you are struck by a wrench or entangled in
the drill string or reamer. Never rotate drill string while installing or removing a reamer.
Heavy reamers must be lifted using the Vermeer reamer carrier or similar device and turned
by hand while the machine is locked out.
