▲CAUTION

Collect all fiber scraps in the dust bin and dispose of them in an approved fiber disposal unit.Do not touch the cleaving wheel blade cutting area.Donotdisassembleorlubricate.ContactTempoformaintenanceand repairs.Store in a dry, clean location in the protective pouch.Failure to observe these precautions may result in injury and may damage the unit.

Operation

1. Open the fiber clamp mechanism and pull the fiber cleaving wheel mechanism back toward yourself.
2. Place the fiber to be cleaved in the desired fiber adapter.

Load 900 micron fiber into the adapter so that the butter is flush with the end of the adapter.

Hint: It is easier to load the fiber into the adapter if the fiber is curled in downward direction from the fiber clamp.

1. Close the fiber clamp mechanism.
2. Push the cleaving wheel mechanism away from yourself to cleavethe fiber.

Note: Dust bin is removed for these photos.

Cleaving Finished Position

1. Open the fiber clamp mechanism.
2. Make sure that the cut fiber end is safely in the dust bin.
3. Remove the adapter with the cleaved fiber from the cleaver.
4. Place the adapter with the cleaved fiber into the 915FS for splicing.

Normal Use and Maintenance

Makesure that the rubber presser feet and the fiber guide groove are clean (no dust and fiber debris). Keep the fiber contact surfaces clean by using isopropyl alcohol with a lint free cleaning wand.

Blade Position Change

1. Loosen blade locking screw.
2. Rotate blade to next scale position.
3. Hold side face of blade and lock screw at new position.

0.7 mm Pencil Lead

1. Move slider back and forth and check if blade touches pencil lead.

If cleave is not good: Check if blade is damaged or dirty at new position.

• If blade drags pencil lead all the way across: Go to "Blade Height Adjustment".
• If blade does not touch pencil lead: Rotate pencil lead ≈ 180^ and try again.

If not sure: Perform a cleave and check cleave angle on 915FS.

If cleave is not good: Go to "Blade Height Adjustment".

Blade Replacement

1. Lay down cleaver with scale numbers on blade facing up.
2. Remove blade locking screw.

Blade Height Adjustment

1. Loosen both compression screws and height locking screw.

① ② ③ ③

1 - Height adjustment screw
2 - Height locking screw
3 - Compression screws for blade height adjustment arm

1. Turn height adjustment screw:

• CW if blade did not touch pencil lead (moves blade up).
- CCW if blade dragged pencil lead across (moves blade down).

1. Tighten height locking screw and both compression screws.
2. Lay 0.7 mm pencil lead across both pressure pads.

2. Ifbladetouchespencillead: Performacleaveandcheckcleaveangle on 915FS.
   Ifcleave is not good: Checkifblade is damaged at current position.

3. If blade drags pencil lead all the way across: Go back to step 1 and adjust CCW until good.
4. If blade does not touch pencil lead: Rotate pencil lead ≈ 180^ and try again.

If not sure: Perform a cleave and check cleave angle on 915FS.

If cleave is not good: Go back to step 1 and adjust CW until good.

Troubleshooting

Failure Mode Cause and Solution
Fiberdoes not cleave.1	Acrylic coating not removed from fiber.Fiber surface not clean.Clean rubber presser feet.Increase height of cleaving wheel.
End face has lip.	Increase height of cleaving wheel.Clean rubber feet.Check rubber feet for wear or abrasion.
End face has shadow or incline angle.	Increase height of cleaving wheel.
Core missing.	Lower height of cleaving wheel.

Note: Contact Greenlee if the above chart does not provide a solution to attaining a reliable cleave.
