HOW TO USE YOUR
PRESSURE WASHER
If you have any problems operating your pressure
washer, please call the pressure washer helpline at
1-800-270-1408.
How to Start Your Engine
The best way to start your engine-powered pressure
washer for the first time is to follow these instructions
step-by-step. This starting information also applies
whenever you start the engine after you have let the
pressure washer sit idle for at least a day.
This pressure washer requires a water source that
flows at least 3.0 gallons per minute. Do not attempt
to siphon water from a non-pressurized container.
Place the pressure washer close enough to an
outside water source so that no more than 50' of
garden hose is needed.
Check that the high pressure hose is tightly
connected to the spray gun and to the pump. See
ASSEMBLY section for illustrations.
Connect the garden hose to water inlet on the
pressure washer pump and turn the water valve on
all the way.
WARNING! Do not run pump without the
water supply connected and turned on. You
must follow this caution or the pump will be
damaged.
Remove dual lance from the spay gun.
Squeeze trigger on spray gun until a steady
stream of water appears.
Apply the safety latch to the spray gun trigger
(Figure 10).
Place the Run/Stop switch to Run.
Press the primer bulb 3 times, waiting 2 seconds
between each push
Note: For a warm engine, do not prime.
Grasp rope handle and pull slowly until you feel
some resistance. Then pull cord rapidly to
overcome compression, prevent kickback and start
the engine. Let rope return to starter slowly.
If after 3 pulls the engine fails to start, disengage the
spray gun safety latch, squeeze the trigger to relieve
water pressure, re-engage the spray gun safety latch
and pull the recoil starter handle rapidly (Max. 3
pulls).
How to Stop Your Pressure Washer
Move the Run/Stop switch to Stop.
Simply shutting off the engine will not release
pressure in the system. Squeeze trigger on the
spray gun to relieve pressure in the hose.
Note: A small amount of water will spray out when
you release the pressure.
How to Use the Spray Gun and Dual
Lance
You now should know how to START your pressure
washer and how to STOP it. The information in this
section will tell you how to adjust pressure and apply
chemicals using the spray gun and dual lance.
DANGER! Never put hands in front of nozzle.
For most effective cleaning, keep spray nozzle
between 8 to 24 inches away from cleaning surface.
If you get spray nozzle too close, especially using
high pressure, you may damage the cleaning
surface.
Do not get closer than 6 inches when cleaning
automobile tires.

Generac Portable Products 2700PSI High Pressure Washer
Applying Detergent
IMPORTANT: Use soaps designed specifically for
pressure washers. Household detergents could
damage the pump.
To apply detergent follow these steps:
Prepare the detergent solution as required by
chemical manufacturer. See chemical bottle for any
instructions
Hang the detergent solution on J hook of the
wireform on the handle.
Place small filter end of the chemical injecting tube
into the detergent container (Figure 11).
CAUTION: Keep the plastic injector tube from
coming in contact with the hot muffler. This will
damage the plastic tube. When inserting the
filter into a cleaning agent bottle, route the
tube so as to keep it from inadvertently
contacting the hot muffler.
Open the chemical valve handle (Figure 12).
IMPORTANT: Detergent cannot be applied without
the water source turned on.
Make sure garden hose is connected to water inlet.
Check that high pressure hose is connected to
spray gun and pump (see ASSEMBLY section
starting on page 6), and start engine.
Apply detergent to a dry surface, starting from the
bottom and working up to avoid streaking.
Allow the detergent to soak in for 3-5 minutes
before washing and rinsing. Reapply to prevent
surface from drying.
For washing, start at lower portion of area to be
washed and work upward, using long, even,
overlapping strokes.
Pressure Washer Rinsing
WARNING: Be extremely careful if you must
use the pressure washer from a ladder,
scaffolding or any other relatively unstable
location. Pressure in a running washer builds
as you climb. When you press the trigger, the
recoil from the initial spray could force you to
fall. The high pressure spray could also force
you to fall if you are too close to the cleaning
surface.
For Rinsing:
Remove the chemical injector hose from the
chemical bottle to stop detergent from flowing.
Spray until the detergent has cleared from the gun.
Turn the chemical valve handle clockwise fully until
it stops. This puts the gun into high pressure mode.
Keep the spray gun a safe distance from the area
you plan to spray.
Apply a high pressure spray to a small area and
then check the surface for damage. If no damage is
found, you can assume it is okay to continue
cleaning.
Start at top of area to be rinsed, working down with
same overlapping strokes as you used for cleaning.

Automatic Cool Down System
(Thermal Relief)
If you run the engine on your pressure washer for 3-5
minutes without pressing the trigger on the spray gun,
circulating water in the pump can reach a
temperature between 140145°F. When the water
reaches this temperature, the automatic cool down
system engages and cools the pump by discharging
the warm water onto the ground. This system
prevents internal damage to the pump.
GENERAL MAINTENANCE
RECOMMENDATIONS
The warranty of the high pressure washer does not
cover items that have been subjected to operator
abuse or negligence. To receive full value from the
warranty, operator must maintain high pressure
washer as instructed in this manual.
Some adjustments will need to be made
periodically to properly maintain your high pressure
washer.
All adjustments in the Service and Adjustments
section of the engine owners manual should be
made at least once each season.
Once a year you should clean or replace the spark
plug, clean or replace the air filter and check the
gun and wand assembly for wear. A new spark plug
and clean air filter assure proper fuel-air mixture
and help your engine run better and last longer.
BEFORE EACH USE
Check engine oil level.
Check water inlet screen for damage.
Check high pressure hose for leaks.
Check detergent inlet hose and filter for damage.
Check gun and wand assembly for leaks.
PRESSURE WASHER
MAINTENANCE
Check and Clean Inlet Screen
Examine screen on the water inlet. Clean if the
screen is clogged or replace if screen is damaged.
Check High Pressure Hose
The high pressure hose can develop leaks from wear,
kinking, or abuse. Inspect hose each time before
using it. Check for cuts, leaks, abrasions or bulging of
cover, damage or movement of couplings. If any of
these conditions exist, replace hose immediately.
DANGER! Water spraying from a leak is
capable of injecting material into skin. Inspect
hose each time before using it. Never repair a
high pressure hose. Replace it with another
hose that meets the maximum pressure rating
of your pressure washer.
Check Gun and Wand
Examine hose connection to gun and make sure it is
secure. Test trigger by pressing it and making sure it
springs back into place when you release it. Put
safety latch in on position and test trigger. You should
not be able to press trigger.
Check In-Line Filter
Refer to Figure 13 and service the in-line filter if it
becomes clogged, as follows:
1.Detach gun and lance from high pressure hose.
Detach lance from gun and remove o-ring and
screen from lance. Flush the screen, gun and lance
with clean water to clear debris.
Figure 13 In-Line Filter Assembly.

2.If the screen is damaged, the O-ring kit contains a
replacement in-line filter screen and an o-ring. If
undamaged, reuse screen.
3.Place the in-line filter screen into the threaded end
of the lance. Direction does not matter. Push the
screen in with the eraser end of a pencil until it rests
flat at the bottom of the opening. Take care to not
bend the screen.
4.Place the o-ring into the recess. Push the o-ring
snugly against the in-line filter screen.
5.Assemble the lance to the spray gun, as described
earlier in this manual.
Check Detergent Hose
Examine the filter on the detergent hose and clean if
clogged. Hose should fit tightly on barbed fitting.
Examine hose for leaks or tears. Replace the filter or
hose if either is damaged.
Purge Pump of Air and
Contaminants
To remove the air from the pump, follow these
steps:
Set up the pressure washer as described in the
ASSEMBLY section and connect the water supply.
Remove the dual lance from the gun.
Squeeze the trigger on the gun and hold.
To remove any contaminants from the pump,
follow these steps:
Set up the pressure washer as described in the
ASSEMBLY section, and connect the water supply.
Remove the dual lance from the spray gun.

OPERATION section.
Squeeze the trigger on the spray gun and hold.
When the water supply is steady and constant,
engage the safety latch and refasten the dual lance.
Cleaning Chemical Injector Hose
If you have used the chemical injector hose you must
flush it with clean water before stopping the engine.
To clean the chemical injector hose:
Place the small filter end of the chemical injector
hose in a bucket of clean water.
Open the chemical valve handle fully on the lance
by turning it counterclockwise. This puts the gun in
low pressure.
Squeeze the spray gun trigger for 1 to 2 minutes to
flush the chemical injector hose.
Shut off the engine.
Important: Simply shutting OFF engine will not release
pressure in the system. When engine has shut down,
squeeze the trigger on the gun to relieve water
pressure in the hose.
Nozzle Maintenance
If the nozzle on the dual lance becomes restricted or
clogged with foreign materials, such as dirt, excessive
pump pressure may develop. If this nozzle becomes
partially clogged, it can cause a pulsing sensation
during use. This generally is not a pump related
problem, but rather a clogged or partially restricted
nozzle.
If the nozzle becomes clogged or partially restricted,
immediately clean the nozzle with the kit included with
your pressure washer by following these instructions:
Shut off the engine and turn off the water supply.
Press trigger to relieve pressure.
Separate the dual lance from the gun.
Use the wire included in the kit (Figure 14) or a
small paper clip to free the foreign materials
clogging or restricting the nozzle.
