Maintenance schedule of Tro-Reel
Please check by the maintenance table based on this maintenance schedule.
Refer to the maintenance table for a concrete check item.
At introduction The 5th year
The 10th year
Maintenance done by the electrical work trader.
The product-life is different in use conditions and the service space, however, It is possible to use it for about t 10 years
by regularly maintaining and the regular service in correct construction.
・Check the presence of remarkable dirt of the surface of the conductor.
(Once every 3 to 6 months) → Clean it with the cotton waste etc.
・ Check the Tro-Reel unit doesn't become it in a zigzag line.
(Once every 3 to 6 months) →Review the size between conductors in the joint.
・Check the Tro-Reel unit is not away from the hanger.
(Once every 3 to 6 months) →Install the Tro-Reel unit on thehanger.
・Check whether there is not crack and a lack of the insulation sheath
(Once every 3 to 6 months)
→Product exchange recommendation that exchanges the Tro-Reel unit.

Check to see if there is any foreign particles
adhering on its sliding surface or if it is seriously contaminated?
Clean with a specific purpose cleaner or waste
cloth.
Once
every
3 to 6

Is there any ark generated protrusion on its
sliding surface?
Remove any protrusion (convex) on the arc
scratch using a file.
Is there damage and crack at the insulating
sheath ?
When damage and crack occurred in the insulating
sheath of the duct, please change the duct.
○
Is there sharpen at the insulating sheath ?
When thickness of the insulating sheath is equal
to or less than 1.2mm, please change the duct.
