Lubrication & Maintenance
Preventative Maintenance Pays!
The handling and spreading of commercial fertilizers is a most severe operation with respect to metal
corrosion� Establish a frequent, periodic preventative maintenance program to prevent rapid damage
to spreading equipment� Proper cleaning, lubrication and maintenance will give you longer life, more
satisfactory service and more economical use of your equipment�
Shut off all power and allow all moving parts to come to rest before performing any
maintenance operation� Failure to comply with this requirement could result in death or
serious injury�
Hydraulic System
Proper oil in the hydraulic system is one of the most important factors for satisfactory operation� Utmost
cleanliness in handling the oil cannot be stressed enough� Keep hydraulic oil in original closed containers,
clean top of container before opening and pouring, and handle in extremely clean measures and funnels�
“Lubrication & Hydraulic Oil Specifications” on page <?>
for selection of the proper hydraulic
fluid for use in the hydraulic system.
Service Schedule
DO NOT check leaks with hands while system is operating as high pressure oil leaks can be
dangerous! If skin is pierced with hydraulic fluid at high pressure seek immediate medical
attention as fluid injected into the skin could cause gangrene if left untreated. Relieve
pressure before disconnecting hydraulic lines or working system� Make sure all hydraulic
fluid connections are tight and all hydraulic hoses and lines are in good condition before
applying pressure to the system� Wear protective gloves and safety glasses or goggles
when working with hydraulic systems� Failure to comply with this requirement could result
in death or serious injury�
DO NOT check for leaks adjacent to 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�
Check hydraulic oil daily by means of sight gauge on hydraulic tank� Add oil as necessary to maintain level
around mid-point of sight gauge. Periodically inspect hoses and fittings for leaks.
Change hydraulic oil filter after first week (or not more than 50 hours) of operation on a
unit�
Controller will warn when filter is restricted. Change filter when warning sounds.
Drain hydraulic tank through drain plug (not through suction outlet), flush, and refill and change filter
element annually. Oil and filter should also be changed whenever oil shows any signs of breaking down
under continued high-pressure operation� Discoloration of oil is one sign of breakdown�
