Extension adapter – ER100
Fig. 6 Extension adapter-ER100 from two views.
When drilling big diameter holes over Ø 550 mm (21.6”)an extension adapter (see fig. 6) must
be used to extend the distance between drill column and spindle, giving more clearance for
bigger diameter drills. Each adapter extends the drill unit 100 mm (4”) further away from the
column, i.e. gives additional clearance for a 200 mm (8”) bigger drill bit.
Mounting of extension adapter
1. Mount the extension adapter on the quick couplings on the carriage. (se fig. 7)
2. Screw the clamp screw into the nut on the carriage. Do not overtighten as the thread in
the nut can be damaged.
3. Fit the gearbox (see”Gearbox - MG41”).
Note: The adapter can be mounted in two positions. In the picture below the adapter is
mounted in the “lower position”.
