7. Start the machine and run it at idle for 3 to 5 minutes
to circulate the fluid and remove any air trapped in
the system.
8. Stop the engine, check the hydraulic oil level, and
check for leaks.
9. Dispose of the used oil at a certified recycling center.
Checking the Hydraulic Lines and
Hoses
Inspect the hydraulic lines and hoses daily for leaks,
kinked lines, loose mounting supports, wear, loose
fittings, weather deterioration and chemical deterioration.
Make all necessary repairs before operating.
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• Ensure that all hydraulic fluid hoses and
lines are in good condition and all hydraulic
connections and fittings are tight before
applying pressure to the hydraulic system.
• Keep your body and hands away from pin
hole leaks or nozzles that eject high pressure
hydraulic fluid.
• Use cardboard or paper to find hydraulic
leaks.
• Safely relieve all pressure in the hydraulic
system before performing any work on the
hydraulic system.
• Get immediate medical help if fluid is
injected into skin.

Adjusting the Air Pressure in Dampener
The air pressure in the dampener on the pump is set at
15 psi (1 bar) by the manufacturer. This is recommended
for nozzle spray pressures between 20 psi (1.3 bar) and
45 psi (3 bar). If different nozzle pressures are required,
set pressure dampener at pressures indicated.
