ALTO’s environmental policy  
A concern for the environment is a natural part of  
our philosophy at ALTO.  
In every area of the company we work diligently to  
reduce or eliminate harmful effects on our environ-  
ment. This concern is also reflected in the design of  
individual ALTO high pressure washers, including  
the 30CA.  
Years from now, when it’s time to retire this ma-  
chine, you’ll find that nearly every plastic compo-  
nent is recyclable and marked with the appropriate  
material recycling symbol.

Safety precautions and warnings  
GROUNDING INSTRUCTIONS  
This product must be grounded. If it should malfunction or break down, grounding provides a path of least  
resistance for electrical current to reduce the risk of electric shock. This product is equipped with a cord  
having an equipment-grounding conductor and a grounding plug. The plug must be plugged into an appro-  
priate outlet that is properly installed and grounded in accordance with all local codes and ordinances.  
DANGER - - Improper connection of the equipment-grounding conductor can result in a risk of electrocu-  
tion. Check with a qualified electrician or service personnel if you are in doubt as to whether the outlet is  
properly grounded. Do not modify the plug provided with the product - - if it will not fit the outlet, have a  
proper outlet installed by a qualified electrician. Do not use any type of adapter with this product.  
Ground Fault Circuit Interrupter Protection  
This pressure washer may be equipped with a Ground Fault Circuit Interrupter (GFCI) on the  
power cord. This device provides additional protection from the risk of electrical shock. Should replacement  
of the plug or cord become necessary, use only identical replacement parts that include GFCI protection.  
EXTENSION CORDS  
Use only 3-wire extension cords that have 3-prong, grounding type plugs and 3-pole cord  
connectors that accept the plug from the product. Use only extension cords that are intended for outdoor  
use. These extension cords are identified by a marking Acceptable for use with outdoor appliances; store  
indoors while not in use. Use only extension cords having an electrical rating (volts AND amps) not less  
than the rating of the product. Examine extension cord before using, and replace if damaged. Do not  
abuse the extension cord and do not yank on any cord to disconnect. Keep cord away from heat and sharp  
edges. Always disconnect the extension cord from the receptacle before disconnecting the product from  
the extension cord.  
WARNING - - To reduce the risk of electrocution, keep all connections dry and off the ground. Do not touch  
the plug with wet hands.  
2.3 Operation  
(also see Sec. 3.0, Operating instructions)  
2.4 Safety devices on the machine  
Bypass/Overpressure relief  
High or low pressure (Sec. 4.2)  
Generally speaking, high pressure loosens soil, and  
low pressure moves it.  
Attack the dirtiestareas first, with high pressure.  
Then complete the task with a combination of high  
and low pressure as appropriate.  
The high pressure side of the pump is equipped  
with a combination bypass and safety valve. This  
valve recirculates water back to the low pressure  
side of the pump when the spray handle is closed  
or the nozzle is blocked. The bypass/safety valve  
also ensures that the pump pressure will never  
exceed the working pressure by more than 300 psi  
(well within the design strength of the pump). At this  
pressure, the pump automatically switches from  
high pressure to bypass mode. The bypass/safety  
valve also relieves pump pressure when the ma-  
chine is stopped.  
Technique (also see Sec. 4.4)  
Generally, its best not to allow areas still being  
cleaned to dry before youve finished. This is espe-  
cially true if youre using detergent. To remove  
something like chewing gum, use high pressure  
and undercutit. To gain reach(ie. for the eaves  
of the house), use high pressure. Experimentation  
will produce the ideal setting for your cleaning task.  
Motor overload protection  
The electric motor features overload protection. If  
an overload occurs (caused by excessive pressure,  
improper extension cord, or defect), the motor will  
stop.

3.0 Operating instructions  
3.1 Connections  
1. High pressure hose  
Max. length of extension hose: 33 ft  
Only use ALTO high pressure hose  
The high pressure hose marked with max. working pressure and temperature should be attached to the  
outlet nipple (1) using the quick coupler (2).  
2. Water connection  
IMPORTANT! Water must not contain  
dirt, sand or other impurities. Using  
dirty water may void your warranty  
coverage!  
Minimum size and length of the inlet  
hose: ½" diam. / 20 ft.  
Maximum water supply pressure: 145 Psi  
Minimum water flow from the tap: 3 gpm  
Clean the inlet water screen monthly  
(or more frequently if required).  
Run water through your garden hose before connecting, to flush it. Mount the MALE quick-connect nipple  
on the garden hose and snap it into the quick-coupler on the machine.  
Note: Connection to municipal water supplies may require mounting a back-flow preventer. If in doubt,  
check local codes.  
3. Power connection  
This product must be grounded.  
Be certain that the voltage, fuse or breaker, power and/or extension cords are as specified in Sec. 2.2.

Operating instructions  
4. Spray handle - accessories  
1
Rinse the nipple before attaching the  
spray lance.  
2
Pull the gray part of the spray handle (1) forward.  
Insert the nipple (2) of the spray lance or accessory in the quick coupling and release #1.

5. Detergent metering unit  
Only use suitable detergents.  
Use of aggressive detergents may  
damage the equipment and affect the  
environment.  
Flush with water after use.  
IMPORTANT: Always set the injector to  
0when not using detergents.  
Detergents are added under low pressure through the built-in metering unit (1). The pickup hose and  
screen (3) of the metering unit is stored near the container support (2). Some container s can be hung on  
the support by the handle. Insert the pickup hose with filter into the bottle or the container. Metering is  
infinitely adjustable from 0-5%. Select the required concentration by turning the knob (3) counter-clockwise,  
until the desired setting is aligned with the arrow. When finished with the detergent system, flush it with  
water (in place of detergent), at setting 5for approximately 1 minute. Return the knob to position 0.  
3.2 Starting procedure  
Turn on the water.  
Vent the machine.  
Turn the start/stop knob (1) to position I.  
Turn on the water supply and squeeze the trigger on the spray handle with the spray lance set at low pres-  
sure (or without a spray lance attached). Let the water run until all air has escaped from the supply hose,  
pump, and high pressure hose (a hissing sound will be heard until the air is gone).  
During start-up, pump pressure may be irregular if air is left in the system. After a short time in operation  
the air will escape from the system, and the pressure will normalize.

be stored on the transport handle (2)  
Store the lance in the lance holder (1)  
Detergent container storage (3).  
The power cord should be coiled and stored on the handle (2) . The high pressure hose should be coiled  
and can be hung in the same place, on top of the cord. The lance should be stored in the lance holder (1).  
3.7 Transport instructions  
Lifting points: Lifting handle (3) and  
under the cabinet, at the front (4).  
The machine has a transport handle (1/3) and wheels so that it is easy to transport.  
The transport handle can be raised or lowered as required. To raise or lower the handle, release the lock  
(2), position the handle, and secure the lock (2). Never lift the machine by the transport handle (1/3) alone!  
Use the lifting handle (1/3) and the bottom of the cabinet (4).  
3.8 Storage - frost protection  
NOTE: The machine should be stored in  
a frost-free area!  
In order to prevent freezing damage to  
the machine, hoses and spray lance,  
they should always be emptied prior to  
storing, as follows:  
1. Stop the machine, shut off the water supply and detach inlet hose and spray lance or accessory.  
2. Restart the machine and squeeze the trigger.  
Let the machine run until no more water comes through the spray handle.  
3. Turn the machine off, detach the high pressure hose and squeeze the trigger until no more water runs out  
of the high pressure hose.  
FROST PROTECTION. If a frost-free storage area is not available, the machine must be protected by  
allowing it to suck in a 50% anti-freeze solution. Hoses and accessories should be emptied of water.

4.0 Using your 30CA  
Applications and some suggestions  
4.1 Typical applications  
Among the most common applications for the ALTO 30CA are:  
Agriculture  
Cleaning and/or sanitizing machinery, implements and livestock areas  
Transportation  
Light industries  
Services  
Cleaning trucks, buses, cars, shop areas and equipment spaces  
Cleaning/degreasing equipment and shop areas.  
Building and kitchen cleaning. Walks, drives and awnings.  
Domestic use  
Autos, motorcycles, campers, boats, trailers, concrete/brick/stone,  
woodwork, roof/gutters, windows, greenhouses, barbecues, garden  
furniture, and many others.  
4.2 Working pressure  
Your ALTO 30CA can be adjusted for virtually any pressure up to its rated working pressure, with a simple  
twist of the knob atop the spray lance.  
Low pressure  
Provides lower pressures and/or activates the internal detergent injector.  
Useful in tight spaces or around sensitive equipment.  
High pressure  
Provides maximum mechanical cleaning action resulting from water jet  
impact.  
Loosens soil and assists detergent action. Stops detergent injection.  
Allows matching the output to specific task requirements.  
In-between  
4.3 Detergents  
A vast number of detergents and other chemicals (such as degreasers and disinfectants) are available for  
use with pressure washers. Selection will depend primarily upon the task at hand, though environmental  
considerations must enter into a responsible decision, as well.  
Your ALTO Distributor or a local chemical company will be able to provide you with guidance.  
It is important to follow the chemical manufacturers instructions regarding use of their chemical! Use only  
as strong a solution as is necessary to accomplish the job. Using more than is necessary is costly. A rule  
of thumb is that, »If it looks like youre getting enough soap, youre using too much«»  
4.4 Operating suggestions  
In cleaning operations using detergents or other solutions, it is generally best to use the following method:  
Step 1 Low pressure application of solution to a dry surface  
Step 2 Wait while the solution works (an important step)  
Step 3 High pressure agitation, and rinse  
Some general advice:  
1) Cleaning solutions generally work best when applied to dry surfaces. Make sure solution is being sprayed  
before pointing the machine at the surface being cleaned.  
2) Do not allow the solution to dry back”  
3) When working on vertical surfaces, apply solution from the bottom up to help prevent streaking which can  
result from high concentrations of solution running down a narrow, dry path to the ground.  
4) Manipulate the spray lance so that water from the high pressure cleaning operation does not rinseareas  
still uncleaned, prematurely. Wash from the bottom up.

5.0 Self-priming  
The ALTO Professional Series high pressure washers are self-priming from as much as 3 feet above a  
water supply source which is not pressurized (such as a tank). Water temperatures above 50°F. will limit  
lift).  
NOTE: Self-priming accelerates wear and tear on the pump and should only be used if necessary.  
It is important to provide adequate filtration when operating from alternative water supplies such as  
streams, tanks, etc. Your Distributor can assist you in providing this protection.  
6.0 Maintenance  
This ALTO high pressure washer is Maintenance-Free! You can, however, contribute to the machines  
reliability and help prevent problems by following this advice:  
The water supply hose should be flushed before connecting it to the machine.  
Before attaching the spray lance or any other accessory on the spray handle, the machine  
should be started and the coupling rinsed.  
When detergents will not be used for an extended period, flush the detergent injection system  
by injectingclean water to prevent clogging of injection system.  
The water inlet screen should be cleaned once a month, or more frequently according to use.  
The machine should be stored in a frost-free area. If the machine freezes, it must not be started  
in that condition. Let the machine, hoses and accessories thaw out before starting.  
NEVER START A FROZEN MACHINE!  
6.1 Clearing the high pressure nozzle  
An obstructed nozzle causes excessive pump pressure and/or pulsation, Should this occur, clearing is  
required immediately.  
1. Stop the machine and disconnect the spray lance.  
2. Using a thin wire or paper clip, clear the nozzle.  
IMPORTANT: This must only be done with the spray lance detached!  
3. Backflush the spray lance with water.  
4. If the pressure remains too high, repeat items 1-3.  
6.2 Cleaning inlet water screen  
Clean the inlet water screen (1) regularly (once a month or  
more frequently depending on water quality).  
Remove the inlet quick-connector. Carefully remove the  
retaining ring (2) with a screwdriver and remove the screen.  
Clean the screen thoroughly and reinstall in the reverse order  
before using the machine again.  
6.3 Cleaning the cabinet air vents  
The machine should be kept clean so cooling air can pass  
freely through the cabinet air vents (3). Do not spray water  
through these vents!
