we cut material with of a large surface area, we should support it on both sides, near its outer edges and near the cut line in such
a way, that the cut material parts slant outside of the cut line. This will prevent jamming the blades.
Make sure, that the thickness of material does not exceed the margin thickness of shear, which is quoted in the table with techni-
cal data.
You should always draw the cut line. This will facilitate work. Shear is designed to cut in a straight line and to cut gentle curves. It
is not suitable for cutting corners.
Shear is equipped with three blades, the outer blades are stationary, and only the middle blade is moving. This arrangement pro-
vides, that both edges of the cut material are not deformed during cutting. However, there is formed a material strap of width given
in the technical data table, which is folded towards the fi xed blades. When you are preparing the workplace you should consider
a place for this strap of material, which is formed during cutting.
Work with the tool,
Grasp the tool with both hands, by light, but fi rm grip, By pressing and holding the trigger you may start the tool and allow it to
reach its full speed. Attach the tool to the edge of the cut material, start cutting, then lead the tool along the previously drawn cut-
ting line. When you are cutting, you should exercise only the pressure, which is needed for cutting, do not guide the tool with the
use of excessive force. The use of excessive force to guide the shear can result in jamming of its blades, rupture of them, as well
as damage to the material, which is being cut.
After the cutting, you may release the trigger and allow the blade to stop. Being catious, turn off the air supply to the tool, and then
disconnect it from the pneumatic system. Proceed to maintenance.
Attention! You should not allow for too long idle operation of the movable blade, as this will lead to premature dulling of blades.
If during work the blades jam in the cut material, you should release the pressure on the trigger and stop your operation, then
release the blades from their jam. When you are resuming the cut you should fi rst start the shear, let them reach their full speed
and then slowly guide them on the cut line. It is forbidden to start cutting by the application of the arrested shear of the material
edge.
MAINTENANCE
Never use gasoline, or any other fl ammable liquid to clean the tool. The vapors can be ignited, causing the tool explosion and
serious injury.
Solvents, which are used to clean the tool holder and the body, can cause seals softening. Thoroughly clean the tool before
starting your work.
In case of fi nding any irregularities in the tool operation, the tool you should be immediately disconnect from the pneumatic
system.
All the elements of the pneumatic system must be protected against contamination. Contamination, that enters the pneumatic
system, can damage the tool and other air system components.
Maintenance the tool before each use
Disconnect the tool from the pneumatic system.
Before each use, let a small amount of liquid preservative (e.g.. WD-40) through the air intake.
Connect the tool to pneumatic system and run it for about 30 seconds on its low speed. This will distribute the liquid preservative
inside the tool interior and will clean it.
Again, disconnect the tool from the pneumatic system.
Let small amount of oil SAE 10 to the inside of the tool, through the air inlet and the holes intended for this purpose. It is recom-
mended to use oil SAE 10 intended for maintenance of pneumatic tools. Connect the tool and run it for a short time on its low
speed.
Attention! WD-40 may not be used as an appropriate lubricating oil.
Remove excess of oil, that spill out through the holes. Left oil may damage the tool seals.
Other maintenance operations
Before each use, you should check whether the tool shows any traces of damages. The blades must be kept clean.
Every 6 months or after 100 hours of operation, you must pass the tool for inspection by the qualifi ed personnel in the repair
shop. If the tool was used without the application of recommended air supply system, you should increase the frequency of the
tool inspections.
Troubleshooting
You should stop using the tool immediately after the disguardy of any fault. Work with a defective tool can cause injury. Any repair
or replacement of tool components must be carried out by qualifi ed personnel in authorized repair facility.
