È PREVENTIVE MAINTENANCE
FOR 72072 DRYERS
Ê Lubrication Precautions
To achieve optimum performance and service life from your Milnor
®
machine and as a warranty requirement,
your machine must be lubricated in strict accordance with the instructions in this section.
ENTANGLE AND CRUSH HAZARD—Belts and pulleys can entangle and crush
body parts.
☞
Lock OFF and tag out power at the wall disconnect before servicing, except
where specifically instructed otherwise in this section.
☞
Insure belt and pulley guards are in place during service procedures.
☞
Permit only qualified maintenance personnel to perform these procedures.
BEARING AND SEAL DAMAGE—Mixing different base greases can cause bear-
ing and seal damage. Consult lubricant manufacturer before using non-speci-
fied lubricants.
1. Do not use a pneumatic grease gun. Take 10-12 seconds to complete each stroke. A grease gun can build
up extremely high pressure which will force seals out of position.
2. Apply the quantity of grease called for in the checklist. Over-lubrication can be as damaging as underlubri-
cation. Where quantities are stated in strokes, one stroke of the grease gun is assumed to provide .0624 fluid
ounce (by volume) (1.77 grams) of grease. Therefore, one fluid ounce (28.3 grams) of grease would be pro-
vided by 16 strokes of the grease gun. Determine the flow rate of your grease gun by pumping one ounce
into a calibrated container. If fewer than 16 strokes are required, all quantities of strokes in the chart should
be reduced accordingly, and if more than 16 strokes are required, the number of strokes should be increased.
Before starting lubrication, make sure the grease gun is working and that you get a full charge of grease
with every stroke.
3. Do not over-lubricate motors. Over-lubrication of a motor can seriously damage it by forcing grease into the
motor.
