1. Be sure air is in "OFF" position when connecting tool to air supply.
2. Always wear approved eye protection when using air tools. If raising dust, wear a
suitable mask.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities, contain chemicals known [to
the State of California] to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
1. Lead from lead-based paints;
2. Crystalline silica from bricks and cement or other masonry products;
3. Arsenic and chromium from chemically treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals:
work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to lter out
microscopic particles.
3. Be sure to disconnect tool from air supply before changing accessories, performing
service on tool and when not in use.
4. As with any tool, use common sense when operating. Do not wear loose clothing or
jewelry that could become caught by moving parts, causing injury. Operate tool a safe
distance from yourself and others in the work area.
5. To ensure long life of the air tool be sure to oil the tool daily before using. See below for
instructions.
6. Follow air source manufacturers directions for connection of regulators, filters, and other
accessories to air source. Do not install quick couplers directly on tool as they put
unnecessary strain on the air inlet threads possibly causing them to wear out
prematurely. Instead, install them on a short length of air hose attached to the tool.
7. Before using the Shear, make sure the blades are properly attached to the tool, and not
dull, cracked, or bent.
8. Allow the Blades to move at full speed before feeding them into the workpiece. Do not
force the Blades into the workpiece when cutting. Apply moderate pressure, allowing the
Blades to cut without being forced. When turning off the shear allow the blades to stop
on their own. Do not press against the blades to stop them.
9. Always use recommended replacement blades, Performance Tool model M597DB.
To replace the Blades:
1. Remove the three Lock Screws (32) and Lock Nuts (33) from the Cutter Housing (31).
2. Remove the Center Blade (35) first.
3. Then remove the Left Blade (34), Right Blade (37), and the two Bushings (36).
Install the new Blades.
1. Place the two Bushings (36) between the new Left Blade (34) and Right Blade (35) and
insert into the Cutter Housing (31).
2. Thread in the two Lock Screws (32), and tighten the two Lock Nuts (33).
IMPORTANT: Before first use, it is recommended to test the Shear on scrap material to
determine the cutting capacity of the Blades.
1. Connect the air supply hose to the Shear.
2. Turn on the compressor, and set its regulator to the recommended 90 PSI for the Shear.
3. In order to keep the air supply hose out of the way, hang it over your shoulder.
4. Make sure to hold the Shear with both hands safely away from the Blades (34, 35, 37).
5. Place the Center Blade underneath the lip of the workpiece. Make sure the Left Blade
(34) and Right Blade (37) are above the lip of the workpiece.
6. Squeeze the Trigger (8) and allow the Blades (34, 35, 37) to move at their fullest speed.
Then move the Blades slowly along the cut line of the workpiece. Either cut completely
through the workpiece or pull the Shear back through the cut portion of the workpiece
before releasing the Trigger. This will help keep the Blades from getting caught in the
workpiece.
7. If the tool requires more force to accomplish the task, verify that the tool receives
sufficient, unobstructed airflow (6 CFM).
8. To prevent accidents, turn off the Shear, detach the air supply, safely discharge any
residual air pressure in the tool, and release the Trigger (8) after use.
9. Clean external surfaces of the tool with clean, dry cloth, and apply a thin coat of tool oil.
Then store the tool indoors out of children's reach.
CAUTION! TO PREVENT TOOL FAILURE RESULTING IN INJURY: Do not exceed the
tool's maximum air pressure rating (90 PSI). If the tool still does not have sufficient force at
maximum pressure and sufficient airflow, then a larger tool may be required.
IMPORTANT SAFETY INFORMATION
OPERATION
Clean air of correct air pressure is recommended for the power supply for this tool. A
maximum of 90 PSI at the tool is recommended for most air tools of this class. Check
specifications section for recommended pressure. (Depending on length of air hose and
other circumstances, air pressure at compressor may need to be increased to 100 PSI to
ensure 90 PSI at the tool.)
Water in the air hose and compressor tank contributes to reduced performance and
damage of the air tool. Drain the air tank and filters before each use and as necessary to
keep the air supply dry.
Hose length over 25’ causes loss in line pressure. Increase hose I.D. or increase
compressor pressure to compensate for the pressure loss. Use an in-line pressure
regulator with gauge if air inlet pressure is critical.
AIR SOURCE
Oil tool before each use. 4 to 5 drops of a good grade Air Tool Oil placed in the air inlet is
sufficient. Use proper air pressure and CFM rating listed for this tool.
Drain water from hoses and
compressor tank. Water in the
air supply line will cause gumming
and loss of power. Clean the air
filter on the supply line and flush
the tool with gum solvent or a
50/50 mix of air tool oil and
kerosene. It may be necessary to
disassemble the tool to properly
clean and re-lubricate.
