Probe Maintenance
WHEELS
Lubricate the wheels by applying drops of a light machine oil on the
wheel bearings. Do
not use
WD-40 or any other lubricant spray that
contains chlorinated solvents. Wheels should be lubricated at the end of
each day of usage, prior to storage of the probe.
Cable Inspection
CABLE
Twists:
Twists indicate a poor coiling technique. Change practice - do not pull
the cable over the side of the reel - reel off and reel on.
Work markings:
The user is dragging the cable through the cable gate. Change practice
- pull cable out then up.
Kinks and/or gouges:
If the kinks do not straighten, there is probably internal damage and
liklihood of intermittent reading failures. If there are any deep gouges,
water can enter the cable. In both cases the bad section of cable must
be removed, either by shortening the cable or replacing the cable.
