US Owner’s manual
































> PP <


We’d like to say, “Thank you!” for choosing one of the ALTO 30HA series machines. This operator’s manual is provided with your new high pressure washer to ensure that you obtain the best results, in the safest manner, with your new machine.

IMPORTANT: This machine is a High Pressure Washer, capable of producing as much as 2100 psi. Read this manual completely, before operating the machine. A complete understanding of the material in this manual will help you avoid possible injury or damage to other objects, as well as damage to the machine, itself.

ALTO's environmental policy

Most of the plastic parts of this model are recycleable, and they have been marked with a recycling symbol and the type of mate-

rial, (i.e. PP).

It is also a part of our concern for environmental problems that the pressure washer is maintenance-free,

meaning that the oil in the high pressure pump will not have to be changed regularly. The oil is in a closed system and is only changed when an eventual service event occurs.

For the production of this high pressure washer the latest technique and technology has been applied. During the final test of the product, the test water is recycled.


IMPORTANT: Read this instruction manual before you start up your high pressure washer for the first time.

This machine is a hot water high pressure washer producing a water jet under high pressure and of a high temperature which is why severe injuries and scalding can occur if the safety precautions are not observed. Therefore a complete understanding of the contents of this instruction manual is required in order to prevent injuries to yourself, objects and persons near-by,and the machine itself.

Check the voltage

Check that the voltage stated on the model tag corresponds to your receptacle.

Power consumption, fuse/breakers

Check the power consumption stated on the model tag and check for correct fuse/breaker.


If these Instructions aren’t followed, it may be dangerous to use your pressure washer.


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-groundingconductor and a grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.

DANGER - - Improper connection of theequipment-groundingconductor can result in a risk of electrocution. 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.


Safety precautions and warnings


Use only 3-wireextension cords that have3-prong,grounding-typeplugs and3-polecord 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. Do not use damaged extension cords. 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.


This pressure washer is provided with a Ground Fault Circuit Interrupter (GFCI) built into the plug of the power supply 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.

WARNING - - To reduce the risk of electrocution, keep all connections dry and off the ground. Do not touch the plug with wet hands.


*Always place the machine at a distance of at least 3 feet from buildings or equipment during operation.

*Never place flammable products (e.g. gasoline, thinner, etc.) or combustible materials (e.g. wood, paper, cloth, etc.) near the machine during operation.

3.0Operating instructions


1.High pressure hose

Only use KEW Technology high pressure steam-capablehoses with an imprinted max. temperature of 150°C.

Max. length of extension hose: 33 ft.

The high pressure hose with imprinted max. working pressure and temperature (150°C) should be attached to outlet socket (1) using the quick coupler (6). The total length of the high pressure hose must not exceed 66 ft.

2.Inlet water connection


Min. length/i.d. of hose: 20 ft, ½".


Clean water inlet screen at least monthly

Max. inlet water pressure 150 psi.

Let water run through the inlet hose to flush any impurities, and clean coupling parts before connecting the supply hose. Attach the inlet water hose to the quick coupling part (2) of the water inlet.

The water supply system must supply at least. 200 gal/hr (3.2 gpm).

If there is a risk of sand in the inlet water (i.e. from your own well), a sand filter should be mounted. Please contact your ALTO distributor for further information.

3.Power connection

Only connect to an approved receptacle with grounding conductor.

Uncoil the power cord before running the machine.

Check voltage, fuse, cords and extension cords according to section »2.1. Start-up«.


Operating instructions


Use clean heating oil or diesel fuel

WARNING! Using the wrong fuel can be hazardous!

Capacity of tank: 4 gal.

Filling of fuel for the burner through the filler opening (4). Capacity of tank: 4 gal. Only use clean heating oil, diesel fuel, or kerosene.

The fuel level can be read on the level indicator (5).

If the burner stops unintentionally, check the fuel level in the tank and if necessary, refill (at least 2 gal). To protect the life of the fuel pump, it is important that the machine is not allowed to run without fuel in the tank.

5.Spray handle - accessories



Clean quick-connectnipple each time the spray lance has been detached.

Pull the grey quick coupler release (7) forward.

Insert the nipple of the spray lance (9) in the quick coupling and release #7.

Tug on the spray lance or other accessory to ensure it’s securely mounted, before starting the machhine.

6.Detergents - metering unit

Only use “normal” detergents. Use of aggressive detergents may damage equipment and affect the environment.

Flush with clean water after use.

Detergents can be added under low pressure through thebuilt-inmetering system (10). Tip the cover (11) out until it stops, and place a container in the holder. Drop the suction hose (12) and filter of the metering unit into the container and close the cover/holder. Metering is infinitely variable (range0-5),and the required dilution is achieved by turning the knobcounter-clockwise,until the required step is against the arrow on the control panel. Max. rate is approximately 5% (25:1). Once detergent application is completed for the day, the system should be flushed through with clean water at Step 5, for approximately 1 min. The knob should then be turned clockwise to Step 0.
