Daily Maintenance
Unplug power cord(s) before servicing or making
any repairs.
1. Inspect hoses for wear. Frayed or cracked hoses
should be replaced to avoid solution pressure loss.
2. Inspect charging cord for wear or damage. To
prevent electrical shock, replace cords that are
frayed or have cracked insulation immediately.
3. Flush the entire system, including spray gun, with
0.5 to 1 gallons of clean, warm water.
4. Check hoses for wear, blockages or damage.
Frayed or cracked hoses should be repaired or
replaced to eliminate solution pressure loss.
5. Check all handles, switches, knobs, electrical
cables and connections on your machine for
damage. If the cable insulation is broken or frayed,
repair or replace it immediately. Do not take
chances with electrical fire or shock.
6. Clean out reservoir, solution screen and nozzle.
7. Clean outside of machine and check for damage.
Cleaning Nozzle
1. Remove nozzle cap and nozzle. Check valve for
wear.
2. Clean nozzle with warm water and a soft bristled
brush. A stainless steel compatible cleaner may
also be used.
3. Reverse steps to re-assemble.
NOTE: Make sure to hold spray gun valve open
(Squeeze gun trigger) during disassembly and re-
assembly.
Monthly Maintenance
1. Check all gaskets for wear and leakage.
2. Check pump pressure; observe spray pattern.
3. Check overall performance of machine.
Yearly Maintenance
1. Check accumulator air pressure.
Squeeze the gun trigger until no fluid or air flows
from the nozzle. Remove the cap on the air valve
of the accumulator and check the pressure with a
tire pressure gauge. The pressure should be 40
PSI. A tire pump can be used to add air.
