MAINTENANCE
NOTES:
• Severe or high cycle usage will require more frequent maintenance checks.
• Inspection and service should always be performed anytime a malfunction is
observed or suspected.
• When servicing, please do some “house cleaning” of the operator and the area
around the operator. Pick up any debris in the area. Clean the operator as
needed.
