TRUPER ENNE-70 Pneumatic Stapler User Manual

TRUPER ENNE-70 Pneumatic Stapler

Product Information

The ENNE-70 is a pneumatic stapler designed for use in wood. It is recommended to operate the stapler at a pressure of 75 PSI – 110 PSI, with a maximum pressure allowed of 110 PSI. The stapler has a cartridge capacity of 100 staples, with a staple gauge of 22 and a staple crown of 3/8″. The staple length ranges from 1/4″ to 5/8″. The air intake connection is 1/4″ NPT, and the hose inner diameter is 3/8″. A centralized filter-oil feeder system is recommended for use with the tool to reduce oil consumption and improve air quality.

Product Usage Instructions

Technical data

CAUTION An increase in the pressure in the line or the inner diameter in the hose diameter shall be considered to compensate the use of very long hoses (longer than 26.2 ft). The hose minimum inner diameter shall be 3/8” and the connectors shall be ¼ NPT. Use good quality couplings and accessories with the right size.

Filter and lubrication requirements

• CAUTION Dust, water and oil specific for using in pneumatic tools are the main cause of potential flaws with the tool. We recommend installing a Brand UNI-LL-1/4 centralized filter-oil feeder system. This system assures lubrication reducing 80% oil consumption significantly increasing the air quality the operator breaths.
• The filter-oil feeder system must be regulated to administer 3 to 6 drops a minute.
• Drain the water in the air compressor tank and also condensation in the hoses before using the tool. Consult the air compressor instructions.

Risk control when using pneumatic tools

Injury risk to head and eyes

• WARNING Compressed air used with pneumatic tools may be dangerous. Objects like vices, burr, splinters, dust and other residues can get shot out at great speed driven by the airflow and enter your eyes or hit your head. Airflow by itself can cause damage on soft tissues in eyes, ears, etc.
• Prevent injury to head and eyes
  • When operating pneumatic equipment wear protecting eyeglasses complying with ANSI Z87.1 Standard. As an additional protection wear a mask.
  • Never aim the airflow to people or animals.
  • Disconnect the air hose from the tool when not in use.
  • Never leave the tool unattended when connected to the air inlet.
  • Before using the tool verify all the parts and accessories are securely fastened.

Risk of explosion

• WARNING Inadequate handling of pressure in pneumatic equipment may cause an explosion and severe injury. Also, using any gas different from compressed air causes explosions.
• Preventing an explosion
  • Before using the tools double-check that the compressed air supply is regulated to the tool specified pressure and it not goes over that level.
  • Never connect the tool into a pressure supply exceeding 200 PSI, neither oxygen nor any other bottled gas, combustible or reactive.
  • Use clean, dry and regulated compressed air with pressure between 75 PSI and 110 PSI.

Hearing loss risk

• WARNING Being exposed to noise generated by pneumatic tool during long periods of time may damage permanently hearing and cause hearing loss.
• Preventing hearing loss
  • When operating pneumatic equipment always wear hearing protection complying with ANSI S3.19 Standard.

Risk of injury

Safety warnings

Safety warnings for using air staplers

Before using the stapler

• To prevent possible injuries, the operator and any other person in the work area shall wear safety glasses with side protection as well as protective helmets in compliance with the Official Mexican Standards (NOM).
• Inspect the tool. Never operate a tool if the lock, the trigger or the springs are not operating; are damaged or lost. Do not make any modification to the lock, trigger or springs.

While using the stapler

• To prevent accidental shots keep your fingers away from the trigger when the tool is nor been used.
• Do not point the tool towards your body, people or animals.
• Disconnect the tool from the air supply before loading staples. Thus, preventing a staple will accidentally be shot during the connection process.
• Do not try to insert a staple on the edge or near the edge of the work piece. If the piece breaks or separates, it would shoot the staples with enough power to cause injury.
• Shoot staples only towards the work surface. Never shoot towards surfaces hard to penetrate on top of another staple or having the tool in steep angle. This could make the staples to bounce exposing the operator to severe injury.
• Do not try to load staples when the trigger is pressed. This action shoots a staple unexpectedly.
• When moving the tool, only hold it by the handle. Never activate the trigger while moving. Never carry the tool holding it by the hose or pulling the hose to move the tool.

After using the stapler

• Disconnect the stapler from the air supply before carrying out any maintenance or unblocking job when leaving the work area or if giving it to another operator.

Parts

Start-Up

Air Supply Connection

• Before connecting to the tool, connect the hose to the compressor and let some air run through the hose and coupling, to verify both are clean.
• If a filter-oil feeder similar to the one recommended in page 3 is not available apply a few drops of oil suitable for tools into the air inlet (A).
• Connect the air hose to the tool with an empty cartridge using a fast coupling (B). Before connecting the hose to the tool double check the staple cartridge is empty.
• The fast coupling is very useful to quickly connect and disconnect the tool and interchange them easily.

Cartridge Loading

• Disconnect the air hose from the tool.
• Verify that there are no staples stuck in the cartridge.
• Open the stapler’s cartridge pressing the cartridge lock (C) and pulling backwards the cartridge cap (D).
• Place the staples onto the open cartridge rib and push them forward as indicated in the illustration.
• Set the staples onto the cartridge rib with the legs downwards.
• Double check the staples are not dirty or damaged.
• Close the cartridge pushing the cover. Block it with the cartridge lock.

Operation

• Turn on the compressor and fill it.
• Regulate the air compressor output pressure to 75 PSI and 110 PSI
• The tool operates with this pressure range. If operating with a higher pressure ranges the useful life of the tool will be decreased.
• Load the cartridge as indicated on page 7.
• Use a piece of scrap wood to verify the tool works correctly.
• Not putting your finger on the trigger position the tool and press the contact lock against the surface to be used (A).
• Without lifting the tool press the trigger to shoot (B).
• Immediately release the trigger and lift the tool (C).
• Position the tool back for subsequent shots.
• In case the staples are not penetrating deep enough, slightly lift the air pressure until reaching the right penetration force. Remember not to exceed 110 PSI

Blocked staple in the shooting orifice

• Disconnect the tool from the air supply.
• Open the nozzle (D) and pull the staple using pliers until removed (E).

Blocked staple in the cartridge

• Disconnect the tool from the air supply.
• Open the cartridge (F).
• Remove the blocked staple with pliers.
• Close the cartridge

Use and care recommendations

• Do not operate without lubrication (it is recommended to use the Truper lubricating filter 19238 UNI-LL-1/4).
• Use only in WOOD.
• Work at the INDICATED PRESSURE to prevent staples from cloging. In case this happens REMOVE THE STAPLE before continuing working.
• Perform periodic MAINTENANCE to your machine.

Maintenance

Lubrication

• Pneumatic tools require constant lubrication all along their working life and while operating. The compressed air the tool needs to function contains humidity that can oxidize the tool’s motor and bearings. To prevent that possibility it is necessary to constantly administer lubricating oil delivered by a Brand UNI-LL-1/4 centralized filter-oil feeder system installed between the air compressor and the tool.
• The exhaust immediately expels any excess oil in the motor. Always keep the exhaust free of obstructions and never point it to people or objects.
• If the tool is not going to be used long periods of time it should be carefully lubricated.
• After each 60 hours operation the tool mechanism needs greasing. Keep in mind that grease in excess may diminish power.

Service

• Servicing the tool shall be carried out every 3 months in an Authorized Service Center. Maintenance service carried out by a non-qualified person may be dangerous and cause personal injury. It also makes the Warranty void.
• Problems with the tool due to lack of recommended dosed lubrication, to fail in following instructions given in this MANUAL or repairs carried out by personnel not certified by will not be covered in the Warranty. We reserve the right to make technical improvements without previous notice.
