OPERATION

• Conveyor Start-Up

Before conveyor is turned on, check for foreign objects that may have been
left inside conveyor during installation . 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 .

MAINTENANCE

• Belt Tracking

HOW IS THE CONVEYOR BELT TRACKED
The belt is tracking by adjusting: Drive Pulley and Tail Pulley . 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:
1 . Make sure conveyor is level across the width and length of unit . Adjust
supports as necessary .
2 . Check to make sure: Drive Pulley and Tail Pulley are square with conveyor
bed . See illustrations Figure 6A, 6B, and 6C . Dimension "A" should be equal
on both sides of the unit (Figure 5B) .
3 . Make sure belt has been properly threaded through conveyor . See Figure
5D .
4 . Make sure belt lacing has been installed correctly and is square with the
belt (Figure 5C) .
5 . Check for improper loading .

IMPORTANT: When belt tracking adjustments are made, they should be
minor (1/16 in . at a time, 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 .
Feed should be in direction of belt travel, centered on belt .
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.
A) Stand at tail pulley looking toward drive and note what direction belt is
traveling .
B) Having observed belt and determined tracking problem, follow procedures
in "How to Steer The Belt ."
HOW TO STEER THE BELT
Condition 1: When the belt is running in the direction (FLOW) with the arrow,
but tracking (drifting) towards Side "X," move the Infeed Tail Pulley nearest
the INFEED end of Side "X" towards the INFEED end of the conveyor .
Condition 2: When the belt is running in the direction (FLOW) with the arrow,
but tracking (drifting) towards Side "Y," move the Infeed Tail Pulley nearest
the INFEED end of Side "Y" towards the INFEED end of the conveyor .
These instructions differ for units that contain Snub Rollers .
The HSQ is not designed to run in reverse .
If belt continues to track improperly, re-check all items covered in "Pre-
Tracking Inspection" on Page 6 and make corrections as necessary .
