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�
WARNING
Shut off all power and allow all moving parts to come to rest before performing any
maintenance operation�
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�
Refer to
“Lubricant & Oil Specifications” on page 61 for selection of the proper hydraulic fluid for use in
the hydraulic system�
Service Schedule
WARNING
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�
WARNING
DO NOT check for leaks adjacent to moving parts while system is operating as there may
be danger of entanglement!
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.
NOTICE!
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�
