Preventative Maintenance; Fcc Notice - Linear HSLG-121 Installation Manual

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.
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.
HSLG Slide Gate Operator Installation Guide
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. 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.
6. 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.
7. Inspect all nuts and bolts for proper tightness and tighten as
necessary.
8. Check all reversing devices for proper function. Inspect all contact
edges for wear and replace if required. Check photoeyes for proper
alignment and function.
9. Check current sensing for proper adjustment when finished with
inspection and maintenance.
10. Inspect the installation area. Are all the warning signs intact and
visible? If they are missing or need replacing, 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.
