SAFETY INSTRUCTIONS
1. Do not operate service or perform maintenance prior to reading and
understanding the instruction manual. Become familiar with and understand
the hazards and limitations of your shear.
2. Wear approved eye protection and protective footwear while operating the
machine.
3. Be certain this machine is properly wired and grounded to conform to the
National Electric Code. The connection of this machine to the power source
should only be made by and inspected by a qualified electrician.
4. Keep hands and body parts clear of the hold down, cutter head and blade
area.
5. Do not exceed the rated capacity of the machine.
6. Never leave the machine in a power on condition when unattended.
7. Always disconnect the machine from the power source before attempting
maintenance, repairs or adjustments.
8. DANGER: Do not attempt to remove the hold down before inserting and
bottoming out the hold down compression bolts (71). The compression bolts
were shipped with the machine. When receiving the shear the bolts are
located inside of the electrical box. Please remove them and store them in a
location to be accessible.
9. Do not remove guards unless required to service the machine. Replace all
protective covers prior to operation.
10. Always wear gloves to protect your hands when handling the shear blades.

11. Insure that the point of operation safeguarding is provided, used and
maintained for any applicable use or service which exposes bodily hazards.
For more details please refer the ANSI Standards for Shear Operations.
12. Keep the Work area around this machine clear and clean to avoid tripping
or slipping.
INSTALLING THE SHEAR
The unit is shipped with a lifting bolt attached on the top of the cutter head. The shear
should be lifted and positioned by using a sling or chain passed through the lifting bolt.
CAUTION: The shear weighs approximately 9,500 lbs. net. Be sure to verify the
maximum load permissible for a given chain or sling.
Locate the machine in a well lighted area on a solid level floor. Use lag screws or bolts
with expandable shields or similar holding devices through the mounting holes on each of
the unit’s side panels (22,51) The center line dimensions for the foundation holes can be
found on the diagram supplied with the manual on page (22).
The shear must be securely anchored to the floor and leveled before operating. Check the
level of the shear with a machinist level both along the length and depth of the machine.
Use the leveling screws (35) provided with the machine to achieve proper level. It may be
advisable to slip a small section of light gauge sheet metal under the leveling screws so
that their adjustment will not penetrate the floor.
ELECTRICAL SPECIFICATIONS
A wiring diagram is located in this manual and inside the electrical box (41). The
connection of this machine to the power source should only be made and inspected by a
qualified electrician. This machine should be properly grounded. Improper wiring may
result in accidental shock which could cause grave injury or death. Motor rotation should
match the directional indicators found on the motor housing. The unit is equipped with
230v/460v, 3 phase, 60Hz motor. The manufacture’s data on the motor will detail its
specifications.

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.

BLADE CLEARANCE
The blade clearance on the LM1010 was set at the factory to .004 in. on the ends of the
blades with a .003 gap in the center of the machine. At this setting, your shear should
provide satisfactory results over a broad range of materials and thickness. However, when
shearing lighter gauge materials a tighter blade gap may be desired. Also, upon turning
the blades to a new edge or after re-sharpening the blades, the blade clearance must be
reset.
CAUTION: Checking the blade gap will require removing the wire
finger guard (80). Do not operate the shear without the guard in place.
To check the blade clearance, set the machine to the jog mode and jog
the cutter head down so that the blades just overlap at the point at
which the inspection is to take place.
WARNING:Disconnect power to the machine prior to making the
measurement. Use a feeler gauge to make the measurement.
The blade clearance adjustment is made in the following manner:
1. Loosen the two table locking bolts (49) located near the mid- section of each side
panel and then retighten the bolts hand tight.
2. Loosen the four table bolts (43), again reasserting only a slight amount of pressure
back to each one.
3. The table positioning screws (20) located at both ends of the table are the means used
to achieve the proper blade clearance. The forward screw pushes the table and bottom
blade toward the cutter head. Likewise, the rear screw adjusts the blade back, thus
increasing the clearance. To set the clearance, place a feeler gauge of the same thickness
as the desired clearance between the two blades. Adjust the forward screw outward until
the feeler gauge is locked between the blades and cannot be removed. Then adjust the
rear screw in the opposite direction until the gauge stock is freed. The opposing actions
of the screws serve to attain a tight, positive setting.
4. After setting the clearance on both ends of the machine, retighten the four table bolts
and the two locking bolts.
5. The blade clearance in the center of the machine controlled by adjusting the center
truss located at the rear of the cutter head. The blade clearance in the center of the shear
should be set at least .001 closer than the dimension chosen for the ends of the blade.
6. Reposition all protective guards and covers.
Please contact the factory if you have any question regarding this procedure.
