Lubrication - Hardi ES 50 Operator's Manual

8. Drain the tank and let the pump run dry. Rinse inside of tank, again
letting the pump run dry.
9. Stop the pump. If the chemicals used have a tendency to block
nozzles, remove and clean them now.
10. Replace all filters and nozzles and store the sprayer. If, from
previous experiences, it is noted that the solvents in the chemicals
are particularly aggressive, store the sprayer with the tank lid open.
NOTE: If the sprayer is cleaned with a high pressure cleaner, we
recommend lubrication of the entire machine.

7.2 Lubrication

Every 40 hours of operation, new grease should be applied to the
pump and boom. Use a high quality multi-purpose lithium based
grease. When greasing the pump, use only 2 to 3 pumps from a
grease gun. For easier application of grease to the boom, place the
wing in the breakaway position. Also oil the M600 control as shown
every 40 hours of operation.
WARNING: TO PREVENT SERIOUS INJURY FROM CRUSHING,
NEVER PLACE FINGERS IN BREAKAWAY CLUTCH.
