9–6) Change of V-ring and waterproof seal (in a case of outdoor type)
Inspect a V-ring and waterproof seal every three years as a guide because waterproof
effect is deteriorated due to aging degradation, and etc.
Consult with the nearest certified service shop when something defective on waterproof is
found by inspection.
In addition, V-ring should be changed with new one when wear and/or rust are found on
the sliding surfaces of it.
As sliding surface is carbon steel, it may get rusted due to rainwater or condensation and
damage an oil seal and V-ring. Therefore periodical rust prevention is required.
