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.
