1-4 GUARDS & GUARDING
All LEWCO standard conveyor equipment is equipped with standard machine guarding methods. It is the responsibility
of the owner, however, to ensure that proper guarding methods are present to comply with OSHA Standards – 29
CFRR – 1910.212 Machinery and Machine Guarding. Special consideration should be given to areas where multiple
pieces of equipment interface. The following are links are provided for reference:
1910.212(a): Machine guarding.
1910.212(a)(1): Types of guarding. One or more methods of machine guarding shall be provided to protect the
operator and other employees in the machine area from hazards such as those created by point of operation, ingoing
nip points, rotating parts, flying chips and sparks. Examples of guarding methods are barrier guards, two-hand tripping
devices, electronic safety devices, etc.
1910.212(a)(2): General requirements for machine guards. Guards shall be affixed to the machine where possible
and secured elsewhere if for any reason attachment to the machine is not possible. The guard shall be such that it
does not offer an accident hazard in itself.
1910.212(a)(3):Point of operation guarding.
1910.212(a)(3)(i):Point of operation is the area on a machine where work is actually performed upon the material
being processed.
1910.212(a)(3)(ii):The point of operation of machines, whose operation exposes an employee to injury, shall be
guarded. The guarding device shall be in conformity with any appropriate standards thereof, or, in the absence of
applicable specific standards, shall be so designed and constructed as to prevent the operator from having any part of
his body in the danger zone during the operating cycle.
1910.212(a)(3)(iii):Special hand tools for placing and removing material shall be such as to permit easy handling of
material without the operator placing a hand in the danger zone. Such tools shall not be in lieu of other guarding
required by this section, but can only be used to supplement protection provided.
SECTION 2 – INSTALLATION
2-1 SUPPORT INSTALLATION
•Bolts for attaching the supports to the bed sections are
shipped in a bag attached to the supports or in a separate
box.
•Set the support height. Subtract frame height dimension
from desired conveying surface. See Figure 2.1. Adjust
the supports to this dimension by sliding inner and outer
legs and tighten bolts.
•Supports should be located at ends of conveyor and
centered under each splice on multi-piece conveyors
(nominal 10’ centers).
•If supports are located on nominal 5’ centers, center
additional supports midway between supports at splices.
Figure 2.1 – Support Height Adjustment
© LEWCO, Inc. 2016 5 40SB Low Profile Slider Bed Belt Conveyor

2-2 CONVEYOR SET-UP
•Mark a chalk line on floor to locate center of the conveyor.
•Place the drive section in position.
•Install remaining sections in order. Conveyor sections have a section number label, which includes the Sales
Order number, Line Item number, and Section Assembly number (last two digits). Conveyors made up of more
than one section are to be assembled in ascending numerical order, starting with Section Assembly 01 at the
product infeed end.
•Check that conveyor is level across both width and length of conveyor. Adjust supports if necessary.
•Check all bed sections for square. See Figure 3.1. Use a string stretched from opposing corners at edge of bed to
aid in straightening conveyor. Ensure that both dimensions are the same. Adjust or shim supports as required.
Both sides of the conveyor must be in the same plane (bed not twisted).
•Tighten all butt couplings and support mounting bolts and lag conveyor to floor.
•Install and track belt.
2-3 BELT INSTALLATION & TRACKING PROCEDURE
•Install belt per Figure 4.1.
•Prior to starting the conveyor, again ensure that
all pulleys and rollers are square and level. Initially,
avoid the situation shown in Figure 4.2.
•Start the conveyor.
•Check for proper belt tension. When properly
adjusted, there should be no slippage between the
drive pulley and the conveyor belt and the drive motor
amp draw will be under the rated full load amps as
indicated on the motor name-plate.
•If the belt slips on the drive pulley, more tension is
required. Adjust the take-up pulley to increase the
tension on the belt. Make small, even adjustments;
Monitoring the results before readjusting.
•If the belt is over-tensioned, the belt lacing will pull away
and the motor amp draw will be high. Adjust the take-up
pulley to decrease the tension on the belt. Make small,
even adjustments; monitoring the results before readjusting.
•Review belt position at all pulleys. Track belt if necessary
based on Figure 4.2.

2-4 PRE-START CHECKS
•MOST speed reducers are shipped with oil, however, ALWAYS check for proper oil level before operating the
conveyor.
•CHECK FOR REDUCER VENT PLUG AND INSTALL IF NECESSARY. See Figure 5.1. To install, remove the
solid plug and replace with vent plug.
•Remove drive chain guard and inspect drive chain and sprockets.
•Chain should have sag on the slack side per Figure 5.2. Measure the sag half way between the two sprockets.
•Sag should be ¼” or 2% of the sprocket center distance.
•Inspect drive sprocket and pulley set screws. These should be tight against the reducer and pulley shafts. Using
a straight edge check to assure the sprockets are aligned by placing the straight edge flush against the sprocket
flanges.
•Re-install chain guard after inspection.
SECTION 3 – MAINTENANCE
Effective operation and useful life of any equipment is directly related to the care and service it receives. A pre-
determined maintenance schedule, including inspection, lubrication, and cleaning, should be established for each
conveyor. Establish and maintain “Log Sheets” on each conveyor to record date and results of inspections, lubrication,
and parts replacements. General inspections of all conveyors should be performed at regular intervals depending on
use and service conditions
NOTICE: Do not perform any work on the conveyor while it is running unless the nature of the maintenance absolutely
requires operation of the conveyor. If the conveyor must be operated to perform maintenance procedures, allow only
experienced conveyor maintenance personnel to do the work. Use extreme caution.

3-2 MAINTENANCE PROCEDURES
3.2.1 Sprocket and Chain Maintenance
•Remove drive chain guard and inspect drive chain and sprockets.
•Chain should have ¼” or 2% sag when measured on the lower run of chain half way between the two sprockets.
See “Pre-Startup Checks”.
•A loose chain can jump the drive sprockets and can cause sprocket wear and failure. A tight chain requires
excessive motor power, and can cause chain and sprocket failure.
•Inspect drive sprocket and pulley set screws for tightness against the reducer and pulley shafts.
•Check sprocket alignment. Misalignment causes wear on one side of the sprocket. Check for a misaligned shaft
or a sprocket off center.
•Check shaft bearing set screws.
•Lubricate the drive chain with SAE-30 oil approximately every 40 hours of operation. Lubricate more frequently
under extreme ambient conditions. Rinse chain in solvent before lubricating.
•Re-install chain guard after inspection and maintenance.

3.2.2 Belt
•Check front, back, and edges of belt for wear, rips, tears, holes, and dirt accumulation. Clean belt with detergent
and water. Replace belt as required.
•Check belt tension under load. The belt should be just tight enough to prevent slipping at the drive pulley with a
rated load. Loose belts cause excessive wear on the drive pulley lagging, and jerky load movement. Tight belts
cause tears, lacing failure, and excessive motor power.
•Check belt lacing for broken, bent, loose, or missing clips and pins. Replace lacing as required.
3.2.3 Motor and Reducer
•Make sure the reducer is filled to the proper level with oil. Make sure breather hole is clean and the orifice is
open.
•Inspect reducer for leaks.
•Use only oil recommended by the reducer manufacturer.
3.2.4 Rollers and Bearings
•Check drive pulley lagging for rips, tears, and missing areas. Replace pulley as required.
•Check all rollers and pulleys for tightness. All rollers must rotate freely. If roller does not turn freely check for dirt
accumulation in bearing area and clean.
•Lubricate all flange type bearings that have grease fittings. Use NLGI Grade 2 Lithium base grease, Shell
Alvania EP2, or equal. Snub roller and return roller bearings are not regreasable.
•Listen to bearing for excessive noise. Replace as required.
3.2.5 Conveyor Bed and Supports
•Check conveyor frame, splices, supports, and bearings for loose or missing hardware. Replace hardware as
required.
3.2.6 Cleaning
•Periodically remove drive chains and clean by immersing in solvent and scrubbing with a wire brush. Rinse
thoroughly and re-lubricate. Verify proper chain tension.
•Clean chain box and keep free of all debris.
