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.

IMPORTANT SAFETY INSTRUCTIONS
To reduce the risk of SEVERE INJURY or DEATH:
1. READ AND FOLLOW ALL INSTRUCTIONS.
2. NEVER let children operate or play with gate controls.
Keep the remote control away from children.
3. ALWAYS keep people and objects away from the gate.
NO ONE SHOULD CROSS THE PATH OF THE MOVING
GATE.
4. Test the gate operator monthly. The gate MUST reverse
on contact with a rigid object or stop when an object
activates the non-contact sensors. After adjusting the
force or the limit of travel, retest the gate operator.
Failure to adjust and retest the gate operator properly
can increase the risk of INJURY or DEATH.
5. Use the emergency release ONLY when the gate is not
moving.
6. KEEP GATES PROPERLY MAINTAINED. Read the
owner’s manual. Have a qualified service person make
repairs to gate hardware.
7. The entrance is for vehicles ONLY. Pedestrians MUST
use separate entrance.
8. Disconnect ALL power BEFORE performing ANY
maintenance.
9. ALL maintenance MUST be performed by a LiftMaster
professional.
