Preventative Maintenance

  WARNING 

Always disconnect power from operator before servicing. Keep clear of gate during operation.

General

Linear gate operators are designed for many years of trouble-free operation and, under recommended operating conditions, will require only minimal maintenance.. To ensure that a unit is ready for operation at all times, and to preclude serious damage or failure, inspect the unit systematically.. Proper adjustments and lubrication should be made as recommended..

Lubrication

✓Bearings — For models which have pillow block style bearings with grease fittings, lubricate at least twice a year with a lithium complex based, petroleum oil NLGI 2 rated grease.. Oilite and precision sealed bearings do not require additional lubrication..

✓Motor — Motors have sealed ball bearings and do not require further lubrication.. If bearing noise develops after several years of operation, bearings should be replaced by a motor repair company, or the motor should be replaced if necessary..

✓Drive Chain and Sprocket — The main drive chain and sprockets should be inspected for wear, cleaned, and wiped down with a lightly oiled rag every six months..

6-Month Preventative Maintenance

1.For operators with V-belts, inspect for wear and replace as necessary.. Check for proper tension and adjust if required.. Check all pulley setscrews for tightness and tighten if necessary..

2.For operators with internal chain drives, inspect chain and sprockets for wear and replace if necessary.. Check for proper tension and alignment, and adjust if required.. Check all hub sprocket setscrews and tighten if required..

3.Check limit switches and limit actuators (cams, limit nuts, etc..) for wear and replace as required.. In rotary limit switch assemblies, wipe the limit shaft clean and apply a light coating of dry lubricant..

4.For operators with magnetic brakes, check for proper adjustment.. Brake disc must run free when the brake is engaged.. For brake assemblies other than C-face style, the brake should be adjusted so that the solenoid plunger throw is between 3/8” to 1/2”.. Too much throw will damage the solenoid.. If the solenoid emits a loud buzzing sound when the motor is run, the brake must be adjusted.

5.In operators which have a disconnect handle, inspect disconnect handle for proper function and lubricate if necessary.. Use a lithium based grease on all moving parts..

6.Inspect all nuts and bolts for proper tightness and tighten as necessary..

7.Check all reversing devices for proper function.. Inspect all contact edges for wear and replace if required.. Check photoeyes for proper alignment and function..

8.Check current sensing for proper adjustment when finished with inspection and maintenance..

9.Inspect the installation area.. Are all the warning signs intact and visible? If they are missing or need replaced, contact Linear.. Be sure there are no control stations mounted within reach of the gate.. Review safety literature with the customer and advise them to remove any such stations found..

FCC Notice

This device complies with FCC Rules Part 15 and Industry Canada Rules & Regulations.. Operation is subject to the following two conditions: (1) This device may not cause harmful interference and (2) this device must accept any interference received, including interference that may cause undesired operation..

For all gate operators, you must inspect the gate for proper operation. The gate should move easily without binding through its entire travel. If the gate does bind, adjust or fix as required. Failure to keep the gate in good working condition will have adverse effects on the operator.
