Operation & Instructions of New Sprayer
Check for OVERHEAD clearance – pay special attention if the center boom is up.
Before starting work, analyze the area to determine the best – and safest – operating procedure. Plan your
travel straight forward, whenever possible. Avoid sharp turns at high speeds.
TR500PHS comes equipped with slip resistant steps for use when loading water or chemicals. Always use
them when mounting or dismounting.
WARNING! Never stand or allow anyone else to stand between the tractor and the sprayer
unless the engine is turned off and parking brake is engaged and the transmission is in park (or
neutral). For stationary PTO operation such as setting the pressure regulator, always place
transmission in park (neutral), engage parking brake and block both tractor and the sprayer tires.
Hitching and Unhitching
All towed loads including the TR500PHS must be hitched to the drawbar.
WARNING! Never allow anyone to stand between the tractor and the TR500PHS while the
tractor is backing up.
To unhitch, move to level ground, block the tires and set the jack before unhitching. Be sure to unlatch and
disengage PTO to complete unhitching. Make sure you use a proper safety hitch pin with safety clip
retainer.
Chemical Operations
Always wear the proper clothing and equipment when handling chemicals. The chemical package should
tell you what is needed.
When dry chemicals are to be used, they should be added when the tank is partially filled and the bypass
agitation valve will start mixing. By the time the tank is filled, the chemicals should be thoroughly mixed.
(The return flow from the pressure regulating valve, while the pump is running, is enough to keep chemicals
mixed during operation.)
It is important to keep dry chemicals mixed because when you do not, they settle out forming a hard, crusty
sediment in:
-The diaphragm pump - if this happens the pump may lock up the next time you try to spray possibly
causing pump damage, PTO shaft damage and grave personal injury.
-The tank – always thoroughly flush the system after chemical operations.
NOTE: Do not use chlorine or Chlorinated liquids or products (like Clorox) to flush the pumps or circuits.
