Initial Use of your Kärcher pump
All Kärcher pumps ship with oil already
inside direct from the factory. There is no
need to add oil.
Pump Inspection
You should routinely make a visual in-
spection of the pressure washer’s pump.
If you notice oil leaking around the pump
seals, you should take the pressure
washer to a Kärcher-authorized service
center for repair. (You can locate a ser-
vice center in your area online at
www.karcher-usa.com/service.)
Pump Maintenance
The pump on your Kärcher pressure
washer does not require maintenance.
Any attempts to service or alter the pump
may damage your pressure washer and
void your product warranty.
Important!
Do not run the engine with a high or low oil
level as this can cause engine damage.
If you have further questions regarding the
engine, please refer to the engine’s oper-
ating manual included with the unit.
Step 1
Check oil level on engine before starting
the unit. Oil level should always be between
the “FULL” and “ADD” marks on the dip-
stick.
Be sure the machine is level when check-
ing the oil level. (Refer to the engine’s op-
erating manual for seasonal grades.).
We recommend that the oil be changed af-
ter the first 5 hours of use, then once every
25 hours.
Step 2
Fill gas tank with unleaded gasoline.
Do not use leaded gasoline.
Step 3
Connect the high pressure hose to the unit’s
high pressure outlet.
Step 4
Connect garden hose to unit’s water inlet.
Step 5
Connect garden hose to the cold water
source and turn water on completely.
Do not use hot water.
Step 6
Trigger the gun to eliminate trapped air, wait
for a steady flow of water to emerge from
the spray nozzle.
Step 7
Pull the choke rod to the CLOSED position
Starting a Warm Engine:
If the engine has run out of fuel, pull the
choke rod to the CLOSED position after
refueling. If the engine has not run out of
fuel, leave the choke rod in the OPEN po-
sition.
