LM1010 SHEAR CONTROL PANEL OPERATION
Please refer to the previous page which shows the 4 functions of the control panel box on
your LM1010 Shear
1. On/Off Push/Pull Switch. This switch is located on the upper left corner of the box.
It is labeled 1. on the previous page. To operate the shear, turn the main disconnect
power switch to the on position and pull the Push/Pull switch to out position until the
light illuminates the switch. The shear is now ready to operate. Please note if your
switch does not illuminate in the out position, you must immediately replace the bulb
located within the switch. It is unsafe to operate this shear without the illuminated
switch. Please contact Tennsmith if you need assistance replacing the bulb.
2. To the right of the Push/Pull Switch is the Jog/Run Switch. This selector type switch
is designated 2 on the previous page. In normal shearing operation this switch should be
in the Run position.
3. The Jog Button is located under the Push/Pull switch on the panel.
It is designated 3 on the previous page. The Jog function allows the operator to engage
the motor and move the cutter head of the shear up or down slowly and hold the cutter
head at a particular position. A secondary function of the Jog function is move the cutter
head up if material is ever wedged between the blades and stalls your machine. The
primary use of the Jog function is to check the clearance between the upper and lower
blades at various points within the shearing cycle.
To operate the Jog function, select Jog on the switch 2 in the upper right corner of the
panel. Next, select either Forward or Reverse on the switch designated 4 next to the Jog
switch, and finally push the Jog switch to move the cutter head of the shear.
Please note: if you are performing a check of the clearance or blade
gap of the shear, the shear must be in an off position at the Push/Pull
switch 1 and at the main disconnect power switch located on the outside
of the box. In addition a lockout tag must be securely placed on the
main electrical connection anytime you are verifying the blade
clearance. If you have any questions on this procedure, please consult
the factory prior to any adjustments on your shear.
4. Stroke Selector Switch This switch is located towards the bottom of the panel and is
designated 5 on the previous page. The switch has two options:
1. Cont – This is for continuous operation of the cutter head of the shear. To engage the
continuous mode, select run on switch 2 (Jog/Run Switch) and select Cont. on the stroke
selector switch. With this mode the cutter head will repeat continuously a full cycle until
the operator releases his foot from the foot pedal of the shear. This mode is useful when
cutting short strips of material that is generally 2” or less.
2. Single – With this mode, the shear will make one complete down and up cycle each
time the foot pedal is pressed. This is the standard mode of operation on this shear.
Please contact the factory if you have any questions regarding the operation of this shear.
