2. External Dimensions
Precautions regarding shape
※The shape of the CVC4 may vary depending on the supported model.
※Make the maximum width of the gun that can be inserted into the CVC4 38 mm or less (when
inserted from the front).
※Even if the gun width is 38 mm, depending on the gun shape and the angle of insertion,
interference may occur in some cases, so that it is only possible to use the product with a narrower
gun.
※Depending on the dresser model that the product is attached to and the insertion angle of the gun,
the gun's insertion width for an oblique insertion layout may be significantly affected by interference.
As a guideline, use a gun width of 30 mm as the maximum.

2. Assembling to the dresser
Assemble to the dresser using the included screws, placing them in the attachment holes on the
adapter shown in Table above.
If there are already any screws at the assembly positions for the dresser, remove them, and
replace them with the included screws.
There are models for which the screw holes that are to be used for assembly to a dresser will vary
depending on the insertion direction. Confirm the corresponding dresser type thoroughly, and then
attach to the main unit.
3. Attaching the hose and hose band (Common to all models)
For the hose, a standard 1-m hose comes included. Cut it before use if it is too long.
If you use the hose with it bent at an acute angle, it may cause chip clogging or hose damage, so
please use it with an appropriate bend angle (100R or more).
Although flame-retardant materials have been used for the hose, it will not be able to withstand
extreme heat.
Do not use it in an environment where it is conceivable that something could ignite.
※If you use the hose with a length of more than 1m, the product may not be able to demonstrate its
proper performance due to lowering the suction force.

4. Attach the dust box, hose and hose band (common to all models)
5. Completion
Connect the air hose to the nipple on the vacuum unit, and it is ready to use.
Use an air hose with an outer diameter Ø10.
Also, use the product in an environment with an air source pressure of 0.5 MPa or more. If the
pressure at the source is less than that, the product may not be able to demonstrate its full suction
capacity.

5. DB-01-SET Chip Disposal Procedure
■
Precaution
ダストボックス DB-01 に切粉が完全に詰まる前にゴミの排出を行ってください。
製品や使用状況により異なりますが、一般的な φ16 チップ約 1500 回研磨で満タン
となります。切粉を廃棄せず溜まったまま本製品を使用しますと、吸引不良の原因と
なります。
■
Procedures
1）Remove the dust box.
2）Dispose of the chips and assemble the dust box.

6. Timing Chart
■
Timing
Make adjustments as necessary, referring to the above.
If you are using a hose that is 1 m or longer for the hose from CVC to the dust box, adjust the CVC
(SOL) suction time so that it is a fairly long time.
7. Maintenance
If any damage to the transparent sheet or brush is confirmed, refer to the appendix, "Diagram of
consumable parts," and replace them.
Periodically check that chips are not getting clogged up inside the CVC, and if any clogging, dust,
etc., is confirmed, remove it.

8. Troubleshooting
■
Suction is poor
1. Check the air pressure. (Recommended: 0.5 MPa.)
2. If the recommended air pressure has been confirmed, check whether the source pipe and the
CVC main unit are connected by a single pipe. When doing so, also check the hose diameter
(Ø10 or more).
※If the pipe branches midway, it will not provide a suction power of 0.5 MPa, and the suction
power will be insufficient.
3. If the hose is bent at an acute angle, the product may not be able to demonstrate its proper
performance.
It may also cause a fault, so use the hose with a moderate curvature (R150 or less).
Furthermore, check that chips have not built up in the chip receiving section (DB-01).
9. Supplement
Required specs for the solenoid valve
→One with a Cv value of 1.0 or more
Recommended solenoid valve type
→ SMC: VP342-5G1-02A
Diameter for the hose from the solenoid valve to the CVC
→ Ø10 or more
Diameter for the hose from the CVC to the dust box
→ Ø32 (Inner diameter)

10. Consumption Parts
※One chip collector sheet and two brushes are required for one chip collector.
※Screws for attachment do not come included with each part.
