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