PREVENTATIVE MAINTENANCE
GENERAL:
OSCO gate operators are designed for many years of trouble-free operation and, under recommended operating conditions, will
require only minimal maintenance. To ensure that your 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 greaseable 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 (slide gate models only). The main drive chain and sprockets should be inspected for wear,
cleaned, and wiped down with a lightly oiled rag every six months.
Swing Gate Arm (swing gate models only). 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.
Barrier Gate Arm (barrier gate models only). Check all bolts for proper tension and tighten if necessary. If the arm has been
warped or damaged, replace as necessary.
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 re-
quired. 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 ad-
justment. Brake disc must run free when the brake is en-
gaged. 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 dis-
connect handle for proper function and lubricate if neces-
sary. 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 photo-
eyes 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 in-
tact and visible? If they are missing or need replaced, con-
tact OSCO. 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.
ADDITIONAL SIX MONTH PREVENTATIVE MAINTENANCE:
For slide and swing 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.
IMPORTANT!
• Always disconnect power from operator before servicing.
• Keep clear of gate during operation.
