For safe use
• Always switch off the Press at the mains and remove the applicator from
the Press before making any adjustments or fitting new parts.
• Always refer to this manual before making any adjustments to JST
Applicators
• All JST Applicators are supplied with a Die-construction sheet; please
refer to this document when ordering spare parts.
• All JST Industry standard Applicators have been designed to operate in
Industry standard presses with a shut height of 135.78mm. If you have any
doubt to whether our applicator is compatible with your Press please do not
hesitate to call our Technical Services Department where one of our
Engineers will be pleased to advise.
• Do not modify or adapt the applicator without prior consent of JST.
• Always ensure that safety guards are fitted to the Press when using your
JST applicator.
• To prevent damage to the dies, always ensure that a protective rubber collar
is fitted between the dials and casting of the applicator when it is removed
from the press.
• Do not make adjustments to the tooling unless qualified to do so.
• When replacement parts are required, use only genuine JST supplied parts.
Die parts that are manufactured using an incorrect heat treatment process
can shatter during use.

1. APPLICATOR RAM SLIDE
1-1 SLIDE ASSEMBLY
The conductor dial (108) and the insulation dial (111) are fixed by the shank (112).
To remove the two disks you must first loosen the 4mm grub screw positioned in the
main body of the slide, now by loosening the shank you can remove both wire disks.
Positioned in the rear of the slide is the cam (119). There are two different cams
available for this applicator. The first type is an pre-feed cam, with this cam fitted
the terminal is present over the anvil when the press is at top dead centre, this type of
cam is commonly used when the applicator is located in a bench press. The other
type is a post-feed cam, this operates in the opposite manner, which means the
terminal feeds forward as the press travels to bottom dead centre, this type of cam is
commonly used when the applicator is located in a fully automatic machine.
1-2 TROUBLE SHOOTING
The dials are difficult to turn
1. Dismantle slide assembly as described above and check for any foreign bodies.
2. Ensure 3mm grub screw located in the insulation dial is not excessively
tightened.
3. Check condition of the positioning Pin (109).
The dials turn freely but do not locate in position correctly
1. Check the condition of the positioning spring (110) and the positioning pin
(109). The Spring may be broken.
2. Ensure 3mm-grub screw located in the insulation dial is adjusted correctly.
2. EJECTOR
2.1 PURPOSE
After the terminal has been successfully crimped on the wire, the terminal may
adhere to the punches; the ejector assures the function of stripping the terminal
from the punches.
2.2 ASSEMBLY
Place the ejector punch with relevant spring (159) into the corresponding slot of
ejector holder (160) ensuring the ejector slides freely up and down when fixed into
position on the front of the crimping punches.

3. UPPER DIE PARTS
3.1 ASSEMBLING UPPER DIE PARTS
To ensure the upper die parts are assembled in the correct orientation the engraved
part numbers must always be facing outwards.
The parts must be fitted in the correct order as detailed below:
1. Conductor spacer (146)
2. Insulation spacer (148)
3.
Block ring (113)
After you have fitted these parts tighten them down with a 5mm-hexagon screw and
check that they are not clamped and move up and down freely.
4. Punch spacer (147)
5. Conductor punch (144)
6. Insulation punch (145)
7. (A Spacer & wire spring are sometimes fitted between the two punches).
8. Punch ring spacer (163)
9.
Ejector (159)+ (160)
After you have fitted these parts, tighten down with a 6mm-hexagon screw and
again check that they are not clamped and punches move up and down freely.
3.2 TROUBLE SHOOTING
The punches or spacers do not move freely
1. Dismantle and check for any foreign bodies.
2. Check the sides of the punches for wear / damage or burrs.
3. Check the parts that are fitted, against the relevant die construction sheet.
