Lubrication & Maintenance
Lubrication
Make sure unit is clean and completely dry�
Lubricate conveyor chain at the end of each
day of usage using a mixture of 75% diesel fuel
and 25% SAE 10 oil� Shut down spinner and run
conveyor at 20 RPM for two full revolutions to
lubricate chain� After each unit washing, allow
to dry, then lubricate�
Lubricate chain through two full revolutions� After each unit washing, allow to dry, then lubricate�
Before filling the unit with spreading material, activate the controller or power switch to run the pump oiler.
Bleed all air from the lines and adjust the two spray nozzles so that the oil mixture sprays vertical onto the
sprockets and chain�
Do not allow lubricants to contact belting as they will
cause the belt to deteriorate and fail prematurely�
Tension
Over-tensioning of conveyor chain will lead to excessive load on the system, causing
excessive chain and sprocket wear and can cause extremely high starting pressures. Under-
tensioning allows conveyor chain to "wrap" around drive sprockets and not exit sprocket
freely, causing excessive excessive chain stretch and surging of the conveyor which will result
in interrupted flow of material to the spinners.
Keep hands, feet, hair and clothing away from moving parts while system is operating as there
may be danger of entanglement! Failure to comply with this requirement could result in death
or serious injury�
Proper chain tension is also a factor in chain and sprocket life� This adjustment is made by turning the
idler screws on each side of the unit at the front idler bearings� See Figure 2� Loosen the idler jam nut
(A) and turn the idler adjustment screw (B) to adjust tension� Turn clockwise to increase tension and, turn
counterclockwise to decrease tension� Adjust idlers equally on each side� Measure from rear of sill to point
where conveyor chain contacts bottom flange of sill. Verify that measurements on both sides of conveyor
are equal and within specified range. See Figure 3.
