Risk Control When Using Pneumatic Tools

Risk of injury in head and eyes
WARNING
• Compressed air out of pneumatic equipment may be dangerous. Objects like brackets, burrs, splinters, dust and other residues may be impelled towards head and eyes due to high speed of the air flow. The air flow itself can only injure soft tissue such as eyes, ears, etc.
CAUTION
• The tool attachments may get lose or break and project particles towards the operator or other operators in the work area.

Risk of explosion
WARNING
• Incorrect handling of pressure in pneumatic equipment may cause an explosion causing severe injuries.

Risk of hearing loss
WARNING
• Being exposed long periods of time to noise pneumatic tools produce may damage hearing permanently causing hearing loss.

Risk of inhaling particles
WARNING

Parts

Assembly

Die Set Up

• Disconnect the tool from the air outlet before replacing the die.

• Select the die you need and set it in the box impeller.

• Always use impact dies with this tool. Do not use dies for hand tools. Consult the catalog to learn about our accessory’s variety.

• Use 1” dies for box impellers.

• Using adaptors for other sizes are not recommended.
  Use only if strictly necessary.

• If the die has orifices always use rubber rings and steel tips when setting it into de box impeller.

• When the box impeller is made with a retaining ring, verify is in good repair. If damaged, replace immediately.

• WARNING When a die has not been secured and adjusted as indicated, it can shoot out and injure the operator.

Start Up

Air Outlet Connection

• Remove the plastic capo (A) covering the air inlet in the handle base.
• Before each use add three to six drops of lubricant with no detergent (B) into the air inlet (C).
• Screw the quick connector D (not included) to the air inlet.
• Connect the air hose using a fast nipple E, (not included) into the quick connector.

Rotation Direction and Torque Selection

• Rotation direction is adjusted with the torque selector (F).
• To tighten a nut or lug, turn the selector to the letter R so that the die rotates clockwise. To loosen, turn the selector to the letter L so that the die rotates counter clockwise.
• To select torque and prevent from tightening too much, a nut or lug, turn the knob to the right or to the left until reaching the desired torque level.
• Using the maximum torque is recommended when there is no torque meter to verify the adequate torque.
• The torque value may vary depending on the air compressor size and the quantity of air (CFM) it delivers.

Turning On

• Turn ON the air compressor and let it fill up.

• Regulate the air compressor outlet pressure to 90 PSI.
  WARNING The tool operates with this pressure range. If operating in a higher pressure range the tool useful life will be shorter.

• Let run some air through the hose and coupling to verify both are clean before connecting into the tool.

• Select the adequate rotation direction and torque.

• Press the trigger so that the die can rotate.

• Release the trigger to stop the die.

Operation

• Set the die in the nut or lug you want to loosen or tighten.
• Before operating the tool double check there is enough space in the back of the tool to prevent getting your hand trapped. The tool goes away from the nut / screw when loosened or tightened.
• Do not try to make contact with the nut or lug with the die moving. Do not press the trigger unless the nut or lug is set correctly inside the die.
• Apply firm and constant pressure without forcing the tool. Otherwise it can be damaged.

Maintenance

Lubrication

• Pneumatic tools need constant lubrication along their useful life and during the operation. Compressed air needed in the tool to run carry humidity which could oxidize the motor and bearing in the tool. To prevent this possibility, it is necessary to constantly deliver lubricating oil through a Brand UNI-LL-1/4 centralized filter-oiler system installed between the air compressor and the tool.

• WARNING
  Any excess of oil in the motor is immediately expelled through the exceeding oil exhaust. Keep the exhaust free of obstructions and never point it towards people or objects.

• If not using the tool for long periods of time, it shall need to be lubricated with care.

• After 60 hours of operation, the tool mechanism needs a little greasing. Excessive grease may diminish power.

Service

• Servicing the tool shall be carried out every 3 months only in a Authorized Service Center. Service and maintenance carried out by not certified  people mat y be dangerous and can cause severe personal injuries as well as making the product Warranty void.
• Malfunction in the tool caused by no using the recommended dose of lubrication, or not complying with this Instructions, or repairs carried out by people not certified by will not be covered with the Warranty. We reserve the right to carry out technical improvements without notice.

Troubleshooting

•  The tool has no oil.
• Low air pressure.
• The hose is leaking.
• Pressure drops.
• Ripped rotor blade.
• There is humidity coming out through the tool exhaust.| • Drain the tool with pneumatic machine oil or rubber solvent.
• Follow the lubrication instructions to lubricate the tool.
• Adjust the tool regulator in the highest position.
Adjust the compressor regulator to 90 PSI maximum.
• Tighten and seal the hose joints if you find any point of leak. Use sealing tape.
• Confirm the hose is the right size.  Long hoses or tools using large volumes of air may need a hose with a 3/4” inner diameter or larger, depending of the total length of the hoses. Do not use many hoses connected with fast mount accessories. This drops the additional pressure and reduces the tool power. Connect hoses directly.
• Take the tool to a Authorized Service.
• Water in the tank (See the air compressor Instructions Manual). Oil the tool and let it run until the water stops. Oil again the tool and run it 1 to 2 seconds.
The tool rotor turns
without auctioning
the trigger.| • The “O-ring” in the inlet is broken.| • Take the tool to a Truper Authorized Service Center, to make the change of “O-ring” broken”

If the problems persist despite carrying out the recommended corrective actions, contact a Authorized Service Center.
