STARTUP
Always use this startup procedure to ensure that the
unit is started safely and properly.
1. Check oil levels.
Engine: Add SAE 30 or 10W–30 weight detergent
oil as necessary.
Pump: Add SAE 20 or 30 weight non–detergent oil
or genuine CAT
pump oil as necessary.
NOTE:
This pressure washer is equipped with a
low–oil sensor that shuts the engine off if the
oil level falls below a certain level. If the unit
stops unexpectedly, check both the oil and
the fuel levels. Check the oil level each time
the unit is refueled.
2. Check fuel level.
WARNING
DO NOT refuel a hot engine. Refueling a hot
engine could cause a fire. Use only fresh, clean
regular or unleaded gasoline. Close the fuel
shutoff valve during refueling.
3. Turn on the water supply.
CAUTION
Never run the unit dry. Costly damage to the pump
will result. Always be sure the water supply is
completely turned on before operating.
4. Trigger the gun until water sprays from the tip
indicating that the air is purged from the system.
5. Open the fuel shutoff valve. Be sure the spark plug
ignition cables are pushed firmly onto the spark
plugs. Put the ignition shutof f switch in the "on"
position and the throttle in the "run" position.
6. Start the engine.
NOTE:
For easier starting, have one person start the
pressure washer while another person
triggers the spray gun.

If the engine is cold, completely close the engine
choke. Press the start button. In cool weather, the
choke may have to be kept closed for 10 to 30
seconds before opening it to keep the engine
running. Otherwise, open the choke as soon as the
engine starts.
If the engine is warm, leave the choke open or
partially closed. Start the engine as described in the
preceding paragraph. When the engine starts, be
sure to open the choke completely.
7. ALWAYS engage the gun' s trigger safety latch
whenever you stop spraying, even for a moment, to
reduce the risk of fluid injection or splashing in the
eyes or on the skin if the gun is bumped or triggered
accidentally.
8. ALWAYS observe the following
avoid costly damage to the pressure washer.
CAUTION
DO NOT allow the pressure washer to idle for more
than 10 minutes. Doing so may cause the
recirculating water to overheat and seriously
damage the pump. Turn off the pressure washer if it
will not be spraying or cleaning at least every 10
minutes. If heated inlet water is used, reduce this
time further.
DO NOT run the pump dry , which will quickly
damage the pump. Be sure the water supply is fully
turned on before starting the pump.
DO NOT operate the pressure washer with the inlet
water screen removed. This screen helps keep
abrasive sediment out of the pump, which could
clog or scratch the pump. Keep this screen clean.
DO NOT pump caustic materials; such materials
may corrode the pump components.
9. See the chemical injector or sandblaster kit manual
for detailed cleaning information if these
accessories are used.
