Maintenance Guidelines

Regularly check lubricating oil condition in the wind motor
Inspect water/gas pipelines and all bolt connections
When working in water, use large-diameter drill head to keep drill pipe 1-2m above water surface
Avoid reverse rotation during operation to prevent drill pipe loss
For short stops, maintain minimal air pressure to prevent sediment ingress
For long stops, thoroughly inspect impactor and reducer before restarting
