4-speed Gearbox MG41
The Pentruder drill system has a 4-speed gearbox to offer a wide speed range for various drill
bit diameters. Performance and safety is increased as the spindle speed cannot be increased
over the adjusted speed during drilling.
See chart on page 15 for correct gear and speed.
Warning!
Do not change speed when the power pack is running. Before changing between
different speeds the two 5/8” or ¾” hoses on the hydraulic motor must be disconnected from
the power pack. Otherwise, the operator might not have full control over the machine. The
power pack can for instance be in a position out of sight from the operator or even on another
floor and be accidentally operated by someone else.
Mounting the gearbox on the carriage or extension adapter
1. Mount the gearbox on the quick release couplings on the carriage (see fig. 8) or the
extension adapter. The quick release couplings make mounting and demounting easy
and quick.
2. The Drill Motor assembly can be fitted in two positions for height, and upside down,
without having to turn the carriage on the column.
3. Screw the clamp screw into the nut on the carriage (see fig. 8). Do not overtighten the
clamp bolt or the nut will be damaged.
4. Adjust the height of the carriage by turning the feed socket (see fig. 8) with a knuckle
bar or with the hydraulc feed unit.
