CAUTION
When servicing, always disconnect operator from electrical power supply.
NOTES
Inspection and service should always be performed anytime a malfunction is observed or suspected.
Limit switches may have to be reset after any major drive chain adjustments.
BG790: If lubricating chain, use only a proper chain lub spray or a lightweight motor oil. Never use grease or silicone spray.
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 if needed.
Severe or high cycle usage will require more frequent maintenance checks.
It is suggested that while you are at the site, take some voltage readings of the operator. Using a VOM, double check the incoming voltage to the operator to make sure it is within ten percent of the operator’s rating.
While you are at the site, now would be a good time to let the owner or manager know about any new items available or any safety items that could and should be added to the site.
LIMITED BEARING LUBRICATION
The barrier gates require very little in the way of maintenance. Motor and shaft bearing normally should not require lubrication. The gear oil in the gear reducer is sealed in. Unless a severe problem causes a seal to break, it should never need replacement. If gear oil is required, use Mobilube C SAE140 or equivalent.
GREASE TURNBUCKLE
Periodically grease the ball ends of the turnbuckle, depending on the gate’s frequency of use.
