No|
---|---
1.| CABLE OUTPUT END :
Check all metal parts and the cable output end for corrosion. Remove any old
grease from the cable ram and motor swivel connections using a mild solvent,
such as kerosene. Spray the cleaned areas with a moisture displacing lubricant
such as WD-40 or equivalent and apply a light coat of good quality marine
grease. Do this with the cable ram fully extended.
2.| CABLE :
Check the entire cable conduit for cracks or abrasion of the plastic cover.
Replace the cable if needed.
3.| HELM :
Check all bolts, nuts, and fasteners for tightness.
4.| WINTER STORAGE :
in winter storage or used infrequently, clean the cable ram per the previously
mentioned instructions. Cycle the steering several times when applying
lubricant. If at
any time the steering system becomes stiff, has an excessive amount of
Freeplay, or shows any change in its operating characteristics, it is
recommended to have the system checked by authorized dealers.
