英語／ENGLISH

1. Always turn off the air supply before disassembling the tool for cleaning andmaintenance purposes.
¡ If the tool is cleaned or disassembled with the air supply connected, injury may result.

2. Do not use the tool with the frame head removed.
¡ Items such as fingers may become caught in the mechanism.

3. Do not bring your face close to the air outlet holes.
¡ Pressurized air containing fine particles is discharged from the air outlet holes during use. Keep eyesaway from this area.

4. Avoid skin contact with substances such as hydraulic oil, lubricating oil and grease.
¡ Such substances may cause inflammation of the skin. If they come into contact with your skin, wash
the affected area thoroughly.

5. Make sure that the workplace is safe, clean and organized.
¡ Accidents can easily occur in untidy workplaces.
¡ If the cut-mandrels are allowed to fall onto the floor, you may slip on them, and injury may result.

6. Avoid uncomfortable postures while working.
¡ You may fall down and injury may result.

7. Keep people who are not involved in work away from the workplace.
¡ Accidents or injury may result.

8. Maintain the tool with due care.
¡ Refer to the Instruction Manual for details on replacing parts and attachments, otherwise injury may occur.
¡ Keep the grip clean and dry at all times, and never let it become greasy, otherwise injury may occur
during use.

9. Use the tool carefully and concentrate on correct operation at all times.
¡ Use the tool with proper care, paying full attention to methods of handling and operation andsurrounding conditions. Accidents and injury may result if this practice is not followed.
¡ Use common sense at all times, otherwise accidents or injury may result.
¡ When you are tired, do not use the tool, otherwise accidents or injury may result.

10. Ask Lobtex to carry out any repair work required.
¡ Repair work should only be carried out by a qualified technician. Please contact your nearest“LOBSTER” distributor, representative, or direct to Lobtex Co., Ltd., Osaka. If the tool is repaired bysomeone without the necessary qualifications and experience, the tool may not perform to optimum
standards, and accidents or injury may result.

11. Do not attempt to modify the tool.
¡ Unauthorized modifications may cause malfunctions which can lead to accidents or injury.

12. Only for EU countries, do not dispose of electric tools together with household wastematerial !
¡ In observance of European Directive 2002/96/EC on waste electrical and electronic equipment andits implementation in accordance with national law, electric tools that have reached the end of theirlife must be collected separately and returned to an environmentally compatible recycling facility.

71 ~ 85 psi).

tWARNING 1 (P.1)

A If installing stainless steel rivets with a diameter of
4.8 mm (3/16") with the AR2000MV(A), set the airpressure to 0.54 ~ 0.59 MPa (5.5 ~ 6 kgf/cm2, 78 ~85 psi).

ATTENTION:
If the air pressure is too high, damage to parts
may occur. If the pressure is too low, some sizeof the rivet may not be correctly installed (cut).

OPERATING THE AIR RIVETER
英語／ENGLISH

1 Select a rivet of a size which is suitable for the workpiece to be riveted.
Replace the nosepiece with one which matches the size of the rivet to be used.

2 (Refer to item 5 in “Preparation Before Use” on page 6.)a hole of appropriate size (0.1 to 0.2 mm larger than the
3 Drill
diameter of the rivet) into the workpiece.

Turn the air controller 90 degree in the ON

4 direction to switch on the vacuum system.
Over 90 degree turn in the ON direction may
cause the damage of the tool. Insert the shaft(mandrel) of the rivet into the tool’s nosepiece.

ATTENTION:
Some rivets have shafts(mandrels) with sharp ends.
Be careful not to injure yourfingers on these ends.

After inserting the shaft (mandrel) of the rivet into the nosepiece,
5 insert
the head of the rivet into the hole.

press the nosepiece of the air riveter against the workpiece.
6 Gently
After checking that there is no gap between the nosepiece and theworkpiece, press the switch.
A When you pull the switch or during the keeping pull position, you may find alittle air leak from the point of this switch. This is not the defective of the quality
but the normal condition.

7 The rivet will be installed into the workpiece.

Release the switch. The cut mandrel (shaft) will then be drawn into the tank unit.
8 NOTE:
Make sure that the cut mandrel has been completely
tWARNING 3 (P.1)
removed before proceeding to the next riveting.

Once the tank unit is about half full, turn the tank cap at the end of the tank in the OPEN

9 direction to remove the cap. Then empty out the cut mandrels from inside the tank unit.
NOTE: It is strongly recommended to dispose of the spent mandrels
as soon the Mandrel collection tank become half filled.
Failure to do this, jamming of the spent mandrels inside the
Guide Pipe will occur and the vacuum will cease to function,
resulting in a back flow of air from the Nosepiece.

＜Operating temperature＞The ambient temperature for working is within the range of 4° ~ 35°C (40° ~ 95°F).

STORAGE¡ Store in a place which is well-ventilated and free from excessive dust and humidity, and where
there is no danger that the tool will fall.
¡ If not using the tool for an extended period of time, carry out a maintenance inspection before
storing it away. (Refer to “Maintenance” on pages 8 ~ 12.)¡ To increase the working life of the tool, it is recommended that you give it periodic overhauls.
Contact the place of purchase or your nearest “LOBSTER” dealer for any overhauls and repair
work required. (A charge will be made for this service.)“LOBSTER” brand Hydraulic Oil is supplied in a plastic filler bottle with the tool,and can also be obtained from your “LOBSTER” dealer or agent in your town.
The AR2000MV(A) and AR2000HV(A) use ultra jaws

TROUBLESHOOTING

TroubleCause

Countermeasure

The rivet does not go 1
in, or the shaft does
not come out after2
riveting.
3

Incorrect combination of replacement parts
being used.

Replace with the correct part which matches
the rivet size. (Refer to page 6.)

Nosepiece or frame head is loose.

Use a spanner or similar to tighten securely.

Jaw case is incorrectly assembled.

Check the jaw case setting position. (Refer topages 8 and 9.)4

Contact surfaces between the jaws and thejaw case head are not smooth.

Clean the jaws and inside the jaw case head,
and apply “LOBSTER” brand jaw lube (or spraytype lubricating oil or the accessory hydraulicoil) to the backs of the jaws. (Refer to page 8.)

5

The inside of the cylinder is dirty so that the
air piston cannot return to its proper position.

Clean inside the cylinder, and apply grease
inside the cylinder and to the O-ring. (Refer topages 10 and 11.)

6

Oil filling was not performed correctly, so that
there is excess hydraulic oil inside the tool.

Loosen the bleed plug to allow the excess
hydraulic oil to drain out. (Refer to page 11.)

1

The rivet length is not correct for the
workpiece thickness.

Use rivets which match the workpiece
thickness.

2

Compressor air pressure is incorrect.

Check the air pressure.

3

Jaw case is incorrectly assembled.

Check the jaw case setting position. (Refer topages 8 and 9.)

4

Jaws are worn.

Replace the jaws. (Refer to page 8.)5Insufficient hydraulic oil, causing a shorter
stroke.

Add hydraulic oil. (Refer to page 13.)

1Spool is not moving properly.

Number of switch
operations increases
before riveting iscomplete.

Piston does notoperate, or returns
very slowly, or
operation is not
smooth.

I

Remove the rear part of changeplug (referto page 12) and push the spool 2~3mm
with a plastic (soft) stick. In case of no
improvement, take the II measure.

II

Clean the spool and apply grease to the Orings. (Refer to page 12.)2

Air outlet hole muffler is blocked.

Replace the muffler. (Refer to pages 10 and 11.)3

The inside of the cylinder is dirty so that the
air piston cannot return to its proper position.

Clean inside the cylinder, and apply grease
inside the cylinder and to the O-ring. (Refer topages 10 and 11.)

The air controller is not open far enough.

Please don't turn the air controller beyond 1/4
of a turn. (Refer to page 7.)

There are too many cut mandrels inside thetank unit.

Remove the tank cap and empty out the cut
mandrels from inside the tank unit.

3

The guide pipe is blocked with cut mandrels.

Take out the guide pipe and remove the cut
mandrels which are blocking it. (Refer to page
8.)

4

The nozzle is dirty, causing the suction power
to drop.

Clean the nozzle. (Refer to page 12.)5

Oil filling was not performed correctly, so that
there is excess hydraulic oil inside the tool,and the air holes are misaligned, causing thesuction power to drop.

Loosen the bleed plug to allow the excess
hydraulic oil to drain out. (Refer to page 11.)The suction power is 1
weak and the shafts(cut mandrels) cannot 2
be drawn out.
