Maintenance and Safety
The SL920 is designed to be MAINTENANCE FREE. However, for optimum performance and safety, the following maintenance procedures should be taken.
Gate Sensitivity Adjustments
The most important thing to maintain on any gate is the safety equipment. As the gate becomes older the amount of force necessary to move the gate will vary. When this happens, the gate sensitivity adjustments may need to be readjusted. Check to see whether the sensitivity may need adjustment at least once a month. Actuate the gate a few times and observe the amount of force that is needed to stop or reverse the gate in both directions. This can be done very easily by standing beside the gate and applying pressure with your hands against the gate while it is moving. Do not stand directly in the path of the gate while doing this experiment. The gate should stop or reverse relatively easy. If it does not stop or reverse easily or does not stop or reverse at all, make adjustments as shown on page 17 of Fine Tuning.
Control Devices
From time to time check to see whether all of the control devices that are connected to the operator are functioning. This is especially important of anything that was installed in regards to safety.
Gate
Having a well maintained gate will ensure that the operator runs smoothly and safely. Occasionally inspect the chain to see whether it is well lubricated and oil the chain if necessary. Use CHAIN AND CABLE LUBE for best results (Available from the manufacturer). Check the wheels and grease them if needed. Check the guide rollers and spray oil on their bearings. Check whether the gate appears to be operating at normal speed to determine if the gate operator may be working harder than usual to overcome friction from damaged bearings.
IMPORTANT SAFETY INSTRUCTIONS
WARNING - To reduce the risk of 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
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 gatehardware.
7)The entrance is for vehicles only. Pedestrians must use separate entrance.
