COMPANY POLICY: The following are the minimum suggested maintenance practices we recommend based upon normal use. Product application, environment and use may dictate a more stringent inspection and maintenance program than suggested. Also, governmental and/or industry regulations must be viewed and complied with when determining the maintenance program for your specific Miller product. Always remember to contact the factory should you need any assistance in establishing or maintaining your maintenance program.

Should any Miller product become worn or deficient, any attempt at repairs will be taken entirely at the risk and cost of the party making such repairs. We will accept any Miller product at the factory for evaluation, repair and/or replacement after the appropriate arrangements have been made with the factory.

NUTS, SET SCREWS, PINS, BOLTS AND RETAINERS
All nuts, set screws, pins, bolts and retainers should be checked for tightness every 14 to 30 days depending on the operating conditions and the product involved. High vibration applications such as pile driving, drilling and/or quar­ry work, will require more frequent inspections.

All set screws are staked at the factory. Should they attempt to back out, re-tighten as necessary and re-stake thoroughly.

Where furnished, all other pins must remain in place. Replace any missing or damaged pins immediately.
