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.
-
Refer to the hydraulic punch instruction manual for proper punch, die, and drawstud selection and setup.
-
Select the appropriate punch, die, and drawstud for the desired hole size.
-
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. -
Depress the Return button to reset the ram to the starting position.
-
Thread the appropriate drawstud completely into the ram in the punching head.
-
Slide the corresponding die onto the drawstud.
The open end of the die should face away from the punching head. -
Insert the drawstud through the pilot hole in the material being punched.
-
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. -
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.
-
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.
