MAINTENANCE
The Speed Reducer is designed to be relatively mainte-
nance-free and is thoroughly lubricated at the factory: how-
ever, periodic lubrication will increase tool life. There are four
important points of lubrication:
1. Pilot Drill
2. Planetary Gearing
3. Planet Gear Shaft
4. Input Shaft Bushing
2, 3, 4 are internal parts and require partial disassembly.
Pilot Drill Lubrication
Each time the pilot drill is removed, a thin coating of
grease should be applied between the fl ats before
being reinserted. This grease provides lubrication for
the piloting hole in the output adapter which guides
the pilot drill. After installation, wipe away all the
excess grease from around the hole to prevent
machining chips from sticking to this area.
INSTALLATION METHOD #2
This method allows the Speed Reducer to be installed in a
1/2” chuck. This also allows the Speed Reducer to be quickly
removed and the drill be used with other holemaking tools.
The disadvantage is the Speed Reducer and drill is heavier
and longer.
You must maintain a fi rm grip on both the
drill and Speed Reducer Clamp Handle.
1. Screw the Triple-fl atted Shank Adapter (04943) into
the input shaft of the speed reducer.
2. Tighten the other end of the Shank Adapter into the
chuck of the drill motor.
3. Slide the clamp handle over the speed reducer and
down to the end closest the drill motor. Rotate
clamp handle to the desired position and tighten
clamp by twisting handle.
4. Install pilot drill, hex washer, and cutter to complete
the setup.
