If you detect any leaks or malfunction, replace the WEH
®
Product or send it to WEH
for maintenance. Stop using the product immediately.
The following maintenance work may be carried out by the operator:
Î
Check the WEH
®
Product for leak tightness and correct functioning – ease of move-
ment, sufficant lubrication, wear, contamination and damage.
Î
Check the sealing surface of the front seal (Pos. 7). If any tears, cracks or damage
are visible on the front seal, replace it. Please refer to
Chapter 9.4.1 Replacement of
front seal (Pos. 7) on page 23
.
Î
Check the lubrication of the front seal (Pos. 7). If the front seal is dry, apply a thin
layer of WEH
®
Lubricant. Special media may extract substances and so lead to
shrinking of the sealing material, thus affecting the sealing function.
Î
Regularly check the clamping jaws for dirt accumulation. Dirt particles can interfere
with the clamping and sealing function, posing a potential hazard.
