Congratulations! We’d like to say, “Thank You” for choosing the CONTRACTOR DIESEL. This instruction 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 2600 psi (180 bar). Read this manual completely, befare operating the machine.
1.0 Safety EN Your CONTRACTOR DIESEL washer has been developed and manufactured in accordance with the latest working safety regulations. Caution! However, to prevent possible personal accidents or damage to any other product, we advise you to read carefully through this section on safety precautions before you operate your washer for the first time. General safety precautions 1. Always use both hands for operating spray equipment to maintain complete control of the lance. 2.
2.0 Motor Protection Device The diesel engine is equipped with a protection device called ”Oil Alert”, which stops the engine if the oil level is insufficient. If this occurs, check the engine for leaks, and after making sure the machine is level, refill it to the proper level. The engine can then be restarted. 3.0 Key photo’s EN (See drawing on the cover) 1. Water inlet and filter (quick-coupler for supply hose) 2. Pump oil level inspection and fill cup 3. Oil drain plug for pump 4. Sludge container 5.
4.0 Application EN ALTO’s diesel powered high pressure washers can be used for all outdoor cleaning jobs for which steam, hot or cold water is used. Detergents can be used (see section 8.5) 4.1 Handling and Transport When handling the machine with a fork lift truck, be sure the forks extend completely under the machine to prevent tipping. When lifting the machine, a sling may be wrapped around the upper frame tubes for lifting. Ensure that personnel aren’t under or near the machine during lifting.
7.0 Functional description The water passes from the inlet connector (a) through a water filter (b) and into the high pressure pump (c). The high pressure water is passed through the regulating unloader (recycling valve) (d) and the first flow control (e) to the throttle valve (f) and through the second flow control (g) into the burner-coil (h). Here the water is heated to the required temperature.
Functional description EN 7.1 High pressure pump 7.4 Spray lance An unloader (recycling valve) and a safety valve are located on the pressure side of the high pressure pump. The unloader recirculates the water to the suction side of the pump when the spray handle is closed or if a nozzle is blocked. The safety valve is adjusted to approx. 25 bar (360 psi) above the working pressure. The high pressure pump should not run idle for more than 5 min.
.0 Connections EN 8.1 High pressure Hose 8.4 Suction Mode Connect the high pressure, steam-capable hose (pos. 24), to the outlet quick-coupling (pos. 10) on the machine front. Use only original ALTO high pressure, steam-capable hoses. The hose should not be exposed to abuse, such as knots, kinks, contact with sharp objects or external heat sources, as this may cause bursting. Only ALTO high pressure, steam-capable hose should be used for extension hoses.
.0 Operating instructions 9.1 Start-up procedure 1. Check that the pump oil level is between the MIN. and MAX. marks (pos. 2). Oil type: ALTO Pump Oil 100. 2. Check the oil level on the Ruggerini engine. Oil type: Choose oil type in accordance with the instructions in the Ruggerini manual. 3. Run water through the inlet hose before connecting in order to remove possible impurities in the hose. Any water supply valve must be fully open in order to provide sufficient water supply. 4.
.0 Storage/frost proofing It is advisable to store the machine in a frost proof place between operations. If this is not possible the machine should be protected in the following way: 1. Disconnect the inlet hose. Remove the lance (pos. 29) and empty it of water. 2. Ensure that the thermostat is set in the blue field, and start the machine, allowing it to run with the spray handle opened until it is empty of water. 3. Place a suction hose in a bucket with 6-8 l (1.5-2 gallons) anti-freeze. 4.
12.0 Maintenance 12.1 Water inlet filter The inlet water connection (pos. 1) contains a filter to prevent impurities entering the highpressure pump. This filter must be inspected at regular intervals, and cleaned as required. The filter can be removed after removing the quick coupling. NOTE: To avoid serious damage to the rubber gasket, the quick coupling should be tightened only gently. EN 2. ENGINE OIL CHANGE Refer to the Ruggerini engine manual for breakin and normal operating oil change requirements.
Maintenance EN 5. Leave the machine for 20 minutes. 6. Start the machine and pump the used solution into a container for proper disposal. 7. Immediately connect a fresh water supply and turn it on. 8. Start the machine, let it work for 5-10 minutes, until all the scale remover is out of the system. 9. If necessary, repeat the procedure from instructions 2 to 8. 12.6 High pressure nozzle care An obstructed nozzle causes an increase in pump pressure. Immediate correction is required. 1.
14.0 Troubleshooting EN Fault Cause Repair The engine fails to start Insufficient diesel supply Battery run down Fuse blown The pump is frozen Refill diesel tank. Recharge the battery*) Exchange fuse. See section 3.0. Let the pump thaw. Working pressure too high Nozzle partly blocked Clean the nozzle. See section 12.6. Working pressure too low Valve for regulation of water volume is not adjusted to max pressure Nozzle worn Motor speed too low Open fully the valve for regulation of water.
