Nuts and Bolts
Check all nuts and bolts for tightness after the first 8 hours of operationthen weekly. Check the condition of cotter pins, roll pins and other fasteners weekly and replace if necessary.
Bolt Grades and Torque
When replacing damaged bolts use only plated Grade 5 bolts unless otherwise specified. Use only bolts of the correct length [Refer to the "Parts" section]. Do not replace lock nuts with nuts and lock washers. Use only original equipment lock nuts.
Recommended Torques in foot pounds for SAE Grade 5 bolts, based on dry assembly:
Hydraulics
Periodically clean dirt and debris from the bottom side of the depth stop ring.
Inspect hydraulic hoses, fittings and cylinders for wear or leaks. Use a piece of cardboard or wood rather than hands to search for suspected leaks. Replace if necessary.
Before applying pressure to the hydraulic system, be sure all connections are tight and that the hoses are not damaged.
DANGER! Do not operate this Equipment with hydraulic oil leaking. Oil is expensive and its presence could present a hazard. Do not check for leaks with your hand! Use a piece of heavy paper or cardboard. High- pressure oil streams from breaks in the line could penetrate the skin and cause tissue damage including gangrene. If oil does penetrate the skin, have the injury treated immediately by a physician knowledge- able and skilled in this procedure.
