Maintenance - Milwaukee M18 FUEL 2874-22HD Operator's Manual

Using the Control Switch
Push for
Clockwise
PUSH TO CENTER TO LOCK
The control switch may be set to three positions:
Clockwise, counterclockwise, and lock. Always allow
the motor to come to a complete stop before using
the control switch.
For clockwise rotation, push in the control switch
from the left side of the tool. Check the direction
of rotation before use. This rotation will produce
right-hand threads when the die is inserted from
the left (front) side of the tool.
For counterclockwise
switch from the right side of the tool. Check direction
of rotation before use. This rotation will produce
right-hand threads when the die is inserted from
the right (back) side of the tool.
To lock the trigger, push the control switch to the
center position. The trigger will not work while the
control switch is in the center locked position. Always
lock the trigger or remove the battery pack before
performing maintenance, changing accessories,
storing the tool and any time the tool is not in use.
Threading
Properly prepare the pipe. Make sure the pipe is
squarely cut and deburred. Pipe cut at an angle can
damage the dies while threading and can cause
difficulty engaging the die head. The pipe must be
stable and secured to prevent tipping during use. Use
appropriate pipe stands to support pipe length.
To cut Right-Handed Threads:
1. Position the die head over the pipe end and sup-
port the tool as directed in "Resisting Threading
Forces".
2. Position the control switch to "clockwise"
dies inserted from the left side of the tool. Position
the control switch to "counterclockwise"
inserted from the right side of the tool.
3. To start the thread, push
against the side grip with the
palm of the free hand,and
slowly pull the trigger.
WARNING! Do not wear
jewelry, loose fitting clothing,
or use a rag while operating
tool. Do not wear gloves
prone to snagging while
pushing on or near moving
parts; this increases the risk
of entanglement and injury.
Once the dies engage the
pipe, threads will be cut as
the dies pull themselves onto
the end of the pipe.
WARNING! Always firmly
hold the tool to resist the
tool forces. Support devices
could, in rare cases, slip and
allow the tool to move.
Push for
Counter-
clockwise
rotation, push in the control
for dies
4. Once the dies have engaged the pipe, stop push-
ing on the side grip and use an oiler to apply a
generous quantity of thread-cutting oil to the area.
This will lower the necessary threading torque,
improve thread quality, and increase die life.
5. Release the trigger when the end of the pipe is
even with the end of the dies.
6. Use the control switch to reverse the tool. Pull
the trigger to thread the die head off of the pipe.
WARNING! Always firmly hold the tool to resist the
tool forces. Support devices could, in rare cases,
slip and allow the tool to move.
7. Release the trigger and remove the tool from
the pipe.
8. Maintain the tool and die head after use. Remove
battery pack and clean oil and cutting debris from
the tool and die. WARNING! Cuttings may be
sharp. Clean up any oil spills to maintain a safe
work environment.
For Left-Handed Threads, reverse the clockwise/
counterclockwise selections.
Inspecting Threads/Using a Ring Gauge
1. Wipe any oil, chips or debris from the thread.
2. Inspect the thread. Threads should be smooth,
complete, and in good form. If irregularities such
for
as thread tearing, thin threads, or pipe out-of-
roundness are seen, the thread may not seal.
3. To check the size of the thread with a ring gauge,
thread the gauge onto the pipe and hand-tighten.
The end of the pipe should be flush with the side
of the gauge (plus or minus one turn). If thread
does not gauge properly, cut off the thread, adjust
the die head, and cut another thread. WARNING!
Using a thread that does not gauge properly can
cause leaks.

MAINTENANCE

To reduce the risk of injury, always
WARNING
unplug the charger and remove the
battery pack from the charger or tool before

MILWAUKEE service facility for ALL repairs.
Maintaining Tool
Keep your tool, battery pack and charger in good
repair by adopting a regular maintenance program.
Inspect your tool for issues such as undue noise,
misalignment or binding of moving parts, breakage of
parts, or any other condition that may affect the tool
