Fluids And Lubricants - SAC 3600 Series Operator's Manual

FLUIDS AND LUBRICANTS

Use SAE multi-purpose high temperature grease with extreme pressure (EP) characteristics on all areas requiring grease
lubrication.
Models equipped with the standard drive pumps will require 3.25 Qts. of synthetic industrial gear oil with an 80W90
rating. It is recommended to change oil after the first 500 hours or 3 months of service, whichever occurs first. Thereaf-
ter, and under normal operating conditions it is recommended to change the oil every 1000 hours or 6 months of service,
whichever occurs first.

Clean around the dipstick and oil fill holes before checking or adding oil. Drain the oil while the unit is still warm.
WARNING: Hot oil can cause severe burns. use extreme care when removing lubrication plugs and vents!
Inspect and clean magnetic drain plug for contamination or metal particles before replacing.

OPERATION
REPLACEMENT PARTS

Use a hand held grease gun for all greasing.
Wipe grease fittings with a clean cloth before greasing to avoid injecting dirt and grit.
Replace and repair broken fittings immediately.
If fittings will not take grease, remove and clean thoroughly. Also clean lubricant passageway.
Replace the fitting if necessary.

IMPORTANT:
When greasing the crosses on the driveshaft al-
ways inspect the condition of the yoke and cross
assemblies for excessive play and/or movement.
Excessive play and/or movement is an indication
that the crosses may have to be serviced and/or
replaced.
