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,
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.
✓ Swing Gate Arm — Check all bolts for proper tension
and tighten if necessary. Make sure the arm folds
overextends itself slightly against the overtravel stop
to reduce the chance that the gate can be backdriven
open. Adjust the close limit slightly if additional travel
is required. Lightly lubricate all pivot points with a light
machine oil.
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 .

6-Month Preventative Maintenance
1. For operators which utilize torque limiting clutches,
check for proper tightness. If there appears to be dust
from wear on the pads, inspect the pads and replace
if necessary. If the clutch cannot be adjusted tightly
enough to move the gate without slipping, the pads
must be replaced.
2. 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.
3. 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.
4. 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.
5. Inspect all nuts and bolts for proper tightness and
tighten as necessary.
6. Check all reversing devices for proper function.
Inspect all contact edges for wear and replace if
required. Check photoeyes for proper alignment and
function.
7. Check current sensing for proper adjustment when
finished with inspection and maintenance.
8. 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.
