Compression cycles
This guide indicates the number of compression cycles that the
TBM15CR-LI can be expected to perform when the battery is fully
charged. These figures are approximate and will vary according
to the charging and other operating conditions, such as
temperature, humidity, and battery condition.
Switch operation
1. The ram advances when the Trigger is depressed and stops
when the Trigger is released.
2. To retract the ram, depress the Release button. The ram
continues to retract while the Release button is depressed. If
the auto-retract feature is activated, the ram will automatically
retract after the crimp is completed. See “Compression
operation” section, page 4 for instructions on enabling and
disabling the auto-retract function.
Compression operation
1. Select the appropriate size dies for the connector being used.
2. Insert the Dies into the Head side and Ram side by sliding the
dies in while pressing the Die Release Pin. If needed, the head
can be opened for easier access by pulling the Head Release
Pin. IMPORTANT: Prior to compression, make sure the head is
closed and the Head Release Pin is fully engaged.
3. Place the connector between the dies. Press the advance
trigger and advance the Ram so the connector is held lightly
between the dies. Do not deform the connector.
4. Insert the conductor into the connector.
5. Press the advance trigger until the compression is complete. A
series of clicks will be heard followed by a release in the
pressure when compression is complete. Once the
compression cycle is complete, the tool will shut off and
retract the ram.
6. If the tool is stopped prior to the auto-retract feature being
activated, press the release button (Switch operation, page 4)
to retract to ram. The ram continues to retract while the
release button is pressed. The ram stops when it reaches the
lower end.
7. Remove the compressed connector from the tool.
Troubleshooting guide:
Before you begin
1. Make sure that the battery is charged. Recheck the battery
after several minutes to make sure the battery is holding its
charge.
2. Use a nonflammable contact cleaner or pencil eraser to clean
the electrical contacts on the battery and tool.
3. Reinstall the battery and check the tool again.
