IMPORTANT SAFETY INSTRUCTIONS
英語／ENGLISH◆ Be sure to read the following Important Safety Instructions carefully and make sure that you
understand them thoroughly before using this tool.
◆ Always wear eye-protection at all times during use. If this is not observed, the cut mandrels
may eject out when the rivets are cut and cause serious injury.
◆ This is the safety alert symbol. It is used to alert you to potential personal injury hazards.
Obey all safety messages that follow this symbol to avoid possible injury or death.
◆ The Important Safety Instructions are divided into tWARNING and tCAUTION .
The differences between these two levels are described below.
tWARNING : Indicates a potentially hazardous situation which, if not avoided, could result in death orserious injury to the operator.

tCAUTION : Indicates a potentially hazardous situation which, if not avoided, may result in moderate
injury to the operator or physical damage.
Moreover, failure to follow the instructions marked with the tCAUTION symbol or cautions without atCAUTION symbol which appear in the text of this manual may also have serious results in some cases.
Always be sure to observe the instructions given in the Important Safety Instructions.

◆ After reading this manual, keep it in a safe place where it is easily accessible to tool users.

tWARNING
1. The air pressure should be kept within the range of 0.49 to 0.59 MPa (5 to 6 kgf/cm2, 71 to 85 psi).
¡If an air pressure which is greater than this is used, the tool may become damaged, and injury or
damage to property may result.

2. Always attach the safety cap before use.
¡If this is not observed, the cut mandrels may eject out when the rivets are cut and cause serious injury.

3. Be sure to remove the frame head when adding hydraulic oil through the cylinder.
¡If the frame head is not removed before adding oil, excess oil may remain inside the tool, and damage tothe tool or personal injury may result. (Except the case when adding hydraulic oil through the bleed plug.)

4. Make sure that the tool and the air source are connected securely.
¡If the threads of the joints do not match or if the screws are not inserted far enough, the air hose may
become disconnected during use and injury may result.
¡Use hose bands to securely connect the air hose joint and air hose. If they are not connected securely
enough, the air hose may become disconnected during use and injury may result.

5. Turn off the air supply before disconnecting the tool from the air source.
¡Compressed air may cause the air hose to whip around, and injury may result.

6. Check that all the tool parts are free from damage before use. Any damaged parts
should be repaired before the tool is used.
¡If the tool is used while any parts are still damaged, injury may result.
¡If the hose is damaged by objects being dropped onto it, for instance, the damaged part may rupture
and accident or injury may result.
¡Don't pull and drag the tool by the air hose. It may trigger some damages on the tool body, breakage ofRotary Joint or some other defects and lead serious troubles with injuries.

the rivet size. (Refer to page 7.)

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 9 and 10.)

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 (orspray-type lubricating oil or the accessory
hydraulic oil) to the backs of the jaws. (Referto pages 9 and 10.)

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 11 and 12.)

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 12.)

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 topage 10.)

4

Jaws are worn.

Replace the jaws. (Refer to page 9.)5Insufficient hydraulic oil, causing a shorter
stroke.

Add hydraulic oil. (Refer to page 14.)

1

Spool is not moving properly.

Number of switch
operations increases
before riveting iscomplete.

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

II

Clean the spool and apply grease to the Orings. (Refer to page 13.)2

Air outlet hole muffler is blocked.

Replace the muffler. (Refer to pages 11 and 12.)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 11 and 12.)ULTRA JAWS (AR2000M(A)/AR2000H(A))
The AR2000M(A) and AR2000H(A) use ultra jaws whichhave greater durability. Be sure to specify “Ultra jaws
M” (AR2000M(A)) or “Ultra jaws H” (AR2000H(A)) as
replacement parts for these models.

HYDRAULIC OIL REQUIREMENTS
Use only clean hydraulic oil, as the viscosity of the oil used willaffect tool performance.

15

I

Remove the rear part of changeplug (referto page 13) and push the spool 2~3mm
with a plastic (soft) stick. In case of no
improvement, take the II measure.

“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. If this is not possible, a good quality
mineral oil with the following properties should also be used.
