WHEN DOING MAINTENANCE, YOU MAY BE EXPOSED TO HOT SURFACES, WATER PRESSURE,
MOVING PARTS, OR FIRE RESULTING IN DEATH. BEFORE PERFORMING ANY MAINTENANCE OR

ENGINE
1. Consult Engine Owner's Manual for manufacturer's
recommendations for any and all engine mainte-
nance.
PUMP
The Annovi Reverberi (AR) pump on your pressure
washer was shipped from the factory with oil. The oil
in your pump must be changed after the first 10 hours
of use and every 50 hours thereafter.
To Check Oil:
To ensure efficient operation and longer life of your pressure washer, a routine maintenance schedule should be
prepared and followed. The following routine maintenance schedule is geared to an unit in a normal working
environment. If necessary, the schedule should be modified to suit the conditions under which your pressure washer
is used. The modifications will depend upon the hours of operation and the working environment. If the pressure
washer is in an extremely dirty and/or hostile environment it will require a greater frequency of all maintenance
checks.
MAINTENANCE
b. If your AR pump does not have a side drain
plug, drain the pump by removing the bottom
drain plug on the underside of the pump with
an 8 mm Allen wrench.
2. Drain oil into a suitable container.
3. Replace oil drain plug and tighten securely.
4. Remove oil fill plug (or dipstick).
5. Add 18.5 oz of 30W non-detergent oil to pump.
6. Replace oil fill plug and tighten securely.
HOW TO CLEAN THE NOZZLES
If a spray nozzle becomes clogged with foreign
material such as dirt, excessive pump pressure may
develop and the spray pattern will change. If a nozzle
becomes partially clogged or restricted, the pump
pressure will pulsate. If this happens, clean the nozzle
immediately using the nozzle cleaning kit supplied with
your pressure washer. The procedure is as follows:
1. Shut off pressure washer and turn off water
supply.
2. Pull trigger on spray gun to relieve any water
pressure.
3. Disconnect quick connect wand from spray gun.
4. Remove nozzle from wand.
5. Inspect nozzle for obstructions, grime, or any
foreign matter that could restrict flow of water.
6. Remove any obstructions with nozzle cleaning
tools provided and back flush with clean water.
7. Direct water supply into nozzle end for 30 seconds
to back flush loosened particles.
8. Take this opportunity to inspect wand for obstruc-
tions. Back flush wand if obstructions are seen.
9. Reassemble nozzle to wand.
10. Reconnect wand to spray gun and turn on water
supply.
11. Start pressure washer and test spray pattern. See
Nozzles in Operation section.
12. If spray pattern is still incorrect, replace nozzle.
1. For units with sight glass:
a. If oil level is low, add oil so oil level is midway
between high and low marks on sight glass.
b. If oil level is high, remove excess oil so oil level
is midway between high and low marks on
sight glass.
2. For units with dipstick:
a. Remove dipstick from pump and wipe clean.
b. Insert dipstick fully into pump, then remove it.
c. Oil level is correct when oil covers the lower 1/2
inch of end of dipstick.
To Change Oil:
1. Remove drain plug using one of the methods
below:
a. If your AR pump has a side drain plug, use a
17 mm wrench to remove the plug and drain
the pump.
