Chuck Maintenance (Fig. 5)
The chuck should be taken apart and
cleaned periodically. Collets should be re-
placed when worn to assure proper grip-
ping of the cable. Do not use a wrench to
tighten the chuck. If the chuck fails to grip
the cable, either a thorough cleaning job or
a new collet is required.
Lubrication (Fig. 6)
Proper and regular lubrication is an impor-
tant factor in determining the useful life of
your MILWAUKEE Drain Cleaner.The tool
has been lubricated at the factory and this
lubrication should be sufficient for six
months to one year depending upon the
amount of use the tool receives. Tools used
consistently on heavy duty production jobs
require lubrication more often. Tools that
have not been used for extended periods
of time should be relubricated before be-
ing put back into service.
WARNING!
To reduce the risk of injury, always
unplug your tool before
performing any maintenance.
Never disassemble the tool or try
to do any rewiring on the tool's
electrical system. Contact a
MILWAUKEE service facility for
ALL repairs.
To lubricate:
1.
Unplug the tool and remove the steel
cable through the chuck.
2.
Remove the four perimeter screws
from the drum.
3.
Carefully pull the drum halves apart by
grasping the motor housing and the
chuck spindle. Set aside the front drum
half.
4.
Remove the 3/8"-24 crown nut, “D”
hole hex washer and the rear drum
half. Set aside the rear drum half and
the parts.
5.
Remove the three screws from the
gearcase.
6.
With the tool resting on the motor hous-
ing, hold the diaphragm firmly against
the motor housing and lightly tap the
gearcase to loosen. If the gearcase
will not dislodge, use two screwdriv-
ers opposite each other to gently pry
apart. If the diaphragm pulls free of
the motor housing, the armature may
dislodge, permitting the brushes to slip
off the commutator. Should this occur,
return the entire tool and all parts to
the nearest MILWAUKEE Service
Center or Authorized Service Station.
7.
Clean out old grease and repack the
gearcase two-thirds full with
MILWAUKEE Type “A” grease - 1 lb.
can (Cat. No. 49-08-4121).
8.
To assemble, reverse the procedure
described above.
WARNING!
Coiled cable can cause injury and
must be removed before drum is
opened.

Starting, stopping and controlling
s p e e d
These tools may be used at any speed
from 0 RPM to full speed.
1.
To start the tool, pull the trigger.
2.
To vary the driving speed, increase or
decrease pressure on the trigger. The
further the trigger is pulled, the greater
the speed.
3.
To stop the tool, release the trigger.
Using forward/reverse switch (Fig. 3)
1.
For forward (clockwise) rotation,
push the forward/reverse switch to
the left.
2.
For reverse (counterclockwise) ro-
tation, push the forward/reverse
switch to the right. Although an inter-
lock prevents reversing the tool while
the motor is running, allow the motor
to come to a full stop before reversing.
Inserting cable into drain (Fig. 4)
1.
Set the forward/reverse switch to the
forward position
2.
Loosen the chuck and remove 10 to
12 inches of the cable from the drum.
3.
Tighten the chuck by hand.
4.
Operate the tool at low speed. Con-
tinue to feed the cable (steps 2 and 3)
into the drain using a back and forth
motion until the obstruction is cleared.
This procedure keeps the cable rotat-
ing and will prevent binding.
NOTE: If the tool binds, stop it immediately.
To unbind drain cleaner
1.
Withdraw the tool a few inches while
in reverse to free the cable.
2.
Stop the tool.
3.
After the tool has come to a complete
stop, switch back to the forward di-
rection.
CAUTION: Extended operation of the tool
in reverse can cause damage to the cable
and accessories.
Removing cable from drain
1.
Tighten the chuck. With the tool run-
ning slowly in the forward direction,
remove 10 to 12 inches of the cable.
2.
Stop the tool. Wash and wipe the ex-
posed cable with a rag. Loosen the
chuck and push the exposed cable into
the drum and retighten the chuck. Re-
peat steps 1 and 2 as necessary until
all the cable is free of the drain.
3.
Before storing the drain cleaner, re-
move the full length of the cable. Coil it
loosely. Then wash and wipe it with
an oiled rag before returning it to the
drum.
To reduce the risk of injury,
always wear eye protection.
