Bypass Valve Service (Serial Number Below 315000000)
The Multi Pro 1750 uses several bypass valves in the
spray system. The bypass valves are non repairable
components. Replace the agitation or spray boom by-
pass valves if necessary.
IMPORTANT: Make sure to remove and neutralize
chemicals from spray components before removing
the pressure relief valve. Wear protective clothing,
chemical resistant gloves and eye protection during
repair.
NOTE: Replace, do not reuse O−rings. Coat O−rings
with vegetable oil before installation to reduce damage
during assembly.
