INTRODUCTION
This manual provides guidelines and procedures for installing,
operating, and maintaining your conveyor. A complete parts
list is provided with recommended spare parts highlighted in
gray. Important safety information is also provided throughout
the manual. For safety to personnel and for proper operation
of your conveyor, it is recommended that you read and follow
the instructions provided in this manual.
● Receiving and Uncrating
Check the number of items received against the bill of
lading.
Examine condition of equipment to determine if any dam-
age occurred during shipment.
Move all crates to area of installation.
Remove crating and check for optional equipment that
may be fastened to the conveyor. Make sure these parts
(or any foreign pieces) are removed.
NOTE: If damage has occurred or
freight is missing, see the “Important
Notice” attached to the crate.
INSTALLATION
● Installation Safety Precautions
for Conveyors and Related Equipment
GUARDS AND GUARDING
Interfacing of Equipment. When two or more pieces of
equipment are interfaced, special attention shall be given to
the interfaced area to insure the presence of adequate guard-
ing and safety devices.
Guarding Exceptions. Wherever conditions prevail that
would require guarding under these standards, but such
guarding would render the conveyor unusable, prominent
warning means shall be provided in the area or on the equip-
ment in lieu of guarding.
Guarded by Location or Position. Where necessary for the
protection of employees from hazards, all exposed moving
machinery parts that present a hazard to employees at their
work station shall be mechanically or electrically guarded, or
guarded by location or position.
When a conveyor passes over a walkway, roadway, or work
station, it is considered guarded solely by location or position
if all moving parts are at least 8 ft. (2.44 m) above the floor or
walking surface or are otherwise located so that the employee
cannot inadvertently come in contact with hazardous moving
parts.
Although overhead conveyors may be guarded by location,
spill guard, pan guards, or equivalent shall be provided if the
product may fall off the conveyor for any reason and if per-
sonnel would be endangered.
HEADROOM
When conveyors are installed above exit passageways,
aisles, or corridors, there shall be provided a minimum clear-
ance of 6 ft. 8 in. (2.032 m) measured vertically from the floor
or walking surface to the lowest part of the conveyor or guards.
Where system function will be impaired by providing the mini-
mum clearance of 6 ft. 8 in. (2.032 m) through an emergency
exit, alternate passageways shall be provided.
It is permissible to allow passage under conveyors with less
than 6 ft. 8 in. (2.032 m) clearance from the floor for other than
emergency exits if a suitable warning indicates low headroom.

● Belt Installation
NOTE: If belt ends cannot be pulled
together by hand, it may be necessary
to loosen take-up in center drive to
minimum position or use a belt puller
so lacing pin can be easily inserted.
The conveyor drive belt has been pre-cut to the proper length
and lacing installed at the factory. To install follow these steps:
BELT FLOW
FIGURE 7A
FIGURE 7B
CAUTION!
Excessive slippage will reduce belt life
and damage drive pulley lagging. Never
apply more tension than is needed.
Overtension will cause extra wear to
belt and will require extra power from
drive.
Thread belt through conveyor as shown in Figure 7B.
Pull ends together and insert lacing pin (Figure 7A).
Adjust belt tension with take-up pulley or tail pulley. Keep
pulley square by moving both take-up bolts an equal
amount. Maintain enough tension so drive pulley will not
slip when carrying the rated load.

● Electrical Equipment
WARNING!
Electrical controls shall be installed and
wired by a qualified electrician. Wiring
information for the motor and controls are
furnished by the equipment manufacturer.
CONTROLS
Electrical Code: All motor controls and wiring shall con-
form to the National Electrical Code (Article 670 or other
applicable articles) as published by the National Fire
Protection Association and as approved by the American
Standards Institute, Inc.
CONTROL STATIONS
A) Control stations should be so arranged and located
that the operation of the equipment is visible from them,
and shall be clearly marked or labeled to indicate the
function controlled.
B) A conveyor which would cause injury when started
shall not be started until employees in the area are alert-
ed by a signal or by a designated person that the con-
veyor is about to start.
When a conveyor would cause injury when started
and is automatically controlled or must be controlled from
a remote location, an audible device shall be provided
which can be clearly heard at all points along the con-
veyor where personnel may be present. The warning
device shall be actuated by the controller device starting
the conveyor and shall continue for a required period of
time before the conveyor starts. A flashing light or similar
visual warning may be used in conjunction with or in
place of the audible device if more effective in particular
circumstances.
Where system function would be seriously hindered
or adversely affected by the required time delay or where
the intent of the warning may be misinterpreted (i.e., a
work area with many different conveyors and allied
devices), clear, concise, and legible warning shall be pro-
vided. The warning shall indicate that conveyors and
allied equipment may be started at any time, that danger
exists, and that personnel must keep clear. The warnings
shall be provided along the conveyor at areas not guard-
ed by position or location.
C) Remotely and automatically controlled conveyors,
and conveyors where operator stations are not manned
or are beyond voice and visual contact from drive areas,
loading areas, transfer points, and other potentially haz-
ardous locations on the conveyor path not guarded by
location, position, or guards, shall be furnished with
emergency stop buttons, pull cords, limit switches, or
similar emergency stop devices.
All such emergency stop devices shall be easily iden-
tifiable in the immediate vicinity of such locations unless
guarded by location, position, or guards. Where the
design, function, and operation of such conveyor clearly
is not hazardous to personnel, an emergency stop
device is not required.
The emergency stop device shall act directly on the
control of the conveyor concerned and shall not depend
on the stopping of any other equipment. The emergency
stop devices shall be installed so that they cannot be
overridden from other locations.
D) Inactive and unused actuators, controllers, and wiring
should be removed from control stations and panel
boards, together with obsolete diagrams, indicators, con-
trol labels, and other material which serve to confuse the
operator.
SAFETY DEVICES
A) All safety devices, including wiring of electrical safety
devices, shall be arranged to operate in a “Fail-Safe”
manner, that is, if power failure or failure of the device
itself would occur, a hazardous condition must not result.
B)
Emergency Stops and Restarts.
Conveyor controls
shall be so arranged that, in case of emergency stop,
manual reset or start at the location where the emer-
gency stop was initiated, shall be required of the con-
veyor(s) and associated equipment to resume operation.
C) Before restarting a conveyor which has been stopped
because of an emergency, an inspection of the conveyor
shall be made and the cause of the stoppage deter-
mined. The starting device shall be locked out before any
attempt is made to remove the cause of stoppage,
unless operation is necessary to determine the cause or
to safely remove the stoppage.
Refer to ANSI Z244.1-1982, American National Standard
for Personnel Protection – Lockout/Tagout of Energy
Sources – Minimum Safety Requirements and OSHA
Standard Number 29 CFR 1910.147 “The Control of
Hazardous Energy (Lockout/Tagout).”

OPERATION
● Operation Safety Precautions
A) Only trained employees shall be permitted to operate
conveyors. Training shall include instruction in operation
under normal conditions and emergency situations.
B) Where employee safety is dependent upon stopping
and/or starting devices, they shall be kept free of
obstructions to permit ready access.
C) The area around loading and unloading points shall
be kept clear of obstructions which could endanger per-
sonnel.
D) No person shall ride the load-carrying element of a
conveyor under any circumstances unless that person is
specifically authorized by the owner or employer to do
so. Under those circumstances, such employee shall
only ride a conveyor which incorporates within its sup-
porting structure, platforms or control stations specifical-
ly designed for carrying personnel. Under no circum-
stances shall any person ride on any element of a verti-
cal conveyor. Owners of conveyors should affix warning
devices to the conveyor reading Do Not Ride Conveyor.
E) Personnel working on or near a conveyor shall be
instructed as to the location and operation of pertinent
stopping devices.
F) A conveyor shall be used to transport only material it
is capable of handling safely.
G) Under no circumstances shall the safety characteris-
tics of the conveyor be altered if such alterations would
endanger personnel.
H) Routine inspections and preventive and corrective
maintenance programs shall be conducted to insure that
all safety features and devices are retained and function
properly.
I) Personnel should be alerted to the potential hazard of
entanglement in conveyors caused by items such as
long hair, loose clothing, and jewelry.
J) As a general rule, conveyors should not be cleaned
while in operation. Where proper cleaning requires the
conveyor to be in motion and a hazard exists, personnel
should be made aware of the associated hazard.
● Conveyor Start-Up
CAUTION!
Because of the many moving parts on the
conveyor, all personnel in the area of the
conveyor need to be warned that the con-
veyor is about to be started.
Before conveyor is turned on, check for foreign objects
that may have been left inside conveyor during installa-
tion. These objects could cause serious damage during
start-up.
After conveyor has been turned on and is operating,
check motors, reducers, and moving parts to make sure
they are working freely.

● Belt Tracking
HOW THE CONVEYOR BELT IS TRACKED
The belt is tracked by adjusting: Drive Pulley, Tail Pulley,
Return Idlers, and Snub Idlers. The same tracking principles
apply to conveyors supplied with end drives, center drives, or
underside take-ups.
PRE-TRACKING INSPECTION
Before attempting to physically track the belt:
Make sure conveyor is level across the width and
length of unit. Adjust supports as necessary.
Check to make sure: Drive Pulley, Tail Pulley, Snub
Idlers, and all Return Idlers are square with conveyor
bed. See illustration 10A, 10B, and 10C. Dimension “A”
should be equal on both sides of unit.
Make sure belt has been properly threaded through
conveyor. See “Belt Installation”, Page 7.
Check for improper loading. Feed should be in direction
of belt travel, centered on belt.
Make sure belt lacing has been installed correctly and
is square with the belt.

● Belt Tracking
(Continued)
CAUTION!
Only trained personnel should track convey-
or belt which must be done while conveyor
is in operation.
IMPORTANT: When belt tracking adjustments are made,
they should be minor (1/16 in. at a time on idlers, etc., should
be sufficient.).
Give the belt adequate time to react to the adjustments. It may
take several complete revolutions around the conveyor for the
belt to begin tracking properly on long, slow conveyor lines.
A) Stand at tail pulley looking toward drive and note what
direction belt is traveling.
B) Having observed belt and determined tracking problem, fol-
low procedures in “How to Steer The Belt”, See Figure 11A.

Condition 2. . . When the belt is running in the direction
(FLOW) with the arrow, but tracking (drifting) towards Side “Y”,
move the Snub Idler nearest the INFEED end of Side “X”
towards the DISCHARGE end of the conveyor.
If Belt Direction (FLOW) is reversed, all the above conditions
will remain the same as in Figure 11A,
except you are now
viewing the conveyor from the opposite end.
If belt continues to track improperly, re-check all items covered
in “Pre-Tracking Inspection” and make corrections as neces-
sary.
NOTE: In all conditions, you are viewing
the Conveyor Belt from the INFEED end.
All corrections will be made from the
INFEED end of conveyor.

MAINTENANCE
● Maintenance Safety Precautions
A) Maintenance, such as lubrication and adjustments, shall
be performed only by qualified and trained personnel.
B) It is Important that a maintenance program be established
to insure that all conveyor components are maintained in a
condition which does not constitute a hazard to personnel.
C) When a conveyor is stopped for maintenance purposes,
starting devices or powered accessories shall be locked or
tagged out in accordance with a formalized procedure
designed to protect all person or groups involved with the con-
veyor against an unexpected start.
D) Replace all safety devices and guards before starting
equipment for normal operation.
E) Whenever practical, DO NOT lubricate conveyors while
they are in motion. Only trained personnel who are aware of
the hazard of the conveyor in motion shall be allowed to lubri-
cate.
