Setup and Operation

Punching
Note: The LS50L2 is equipped with a microprocessor to control the operation. It automatically shuts off if punching does not begin within 1 second after pulling the trigger. This guarantees the entire stroke is available for punching and saves power.

1. Refer to the hydraulic punch instruction manual for proper punch, die, and drawstud selection and setup.

2. Select the appropriate punch, die, and drawstud for the desired hole size.

3. Determine and mark the exact location for the hole.
   Use a Greenlee Kwik-Stepper step bit to drill a pilot hole slightly larger than the drawstud being used.

4. Depress the Return button to reset the ram to the starting position.

5. Thread the appropriate drawstud completely into the ram in the punching head.

6. Slide the corresponding die onto the drawstud.
   The open end of the die should face away from the punching head.

7. Insert the drawstud through the pilot hole in the material being punched.

8. Thread the punch (cutting edge facing the material) onto the drawstud until the punch assembly is tight on the material surface.
   Note:
   • All of the punch threads must be engaged with the drawstud threads. If any punch threads are not engaged, reassemble the setup.
   • For SPEED PUNCH , slide the punch onto the drawstud (cutting edge facing the material) and secure the SPEED LOCK to the drawstud.

9. Press and hold the trigger to complete the punch cycle. The LS50L2 driver will automatically stop when it senses the punch is completely through the material.

10. Unscrew the punch from the drawstud. Slide the die

IMPORTANT
Release the trigger when the punch completes the hole. The LS50L2 may not sense when a hole is made in sheets thinner than 18 ga (1 mm) and soft materials (such as plastic, etc.).
off the drawstud and remove any slugs from the die.
Note: For SPEED PUNCH remove the SPEED LOCK. Slide the punch off the drawstud; then slide the die off the drawstud and remove any slugs from the die

Charging the Battery
Read the instructions supplied with the battery charger.
LED Work Light (white)
This LED automatically turns on when the trigger is pulled. It remains on for 10 seconds after the trigger is released.
LED Indicator (red)
This tool is equipped with a special circuit board incor- porating several important features to inform the user about the current status of the unit. The LED signals in the following cases:

at beginning of cycle
Tool will not start, and constant light for 20 seconds when trigger is released| | Battery charge is below 16 V at beginning of cycle
Tool will stop, and constant light for 20 seconds after trigger is released| | Battery voltage drops below 13 V during cycle
Tool will stop, and flashing light for 20 seconds when trigger is released| | Motor current exceeds 20 A during cycle
Circuit has become too hot
