6.0Maintenance

6.1General

To ensure that your ALTO high pressure washer is always in an operational condition it is advisable to have it checked by an ALTO service technician at regular intervals. However, with respect to exposed components, a minimal maintenance program helps ensure a prolonged and problem-free operation.

Therefore, it’s a good idea to make a habit of the following:

zBefore attaching the inlet water or high pressure hose, the quick couplers should be free of dirt and sand.

zBefore attaching the spray lance or any other accessory on the spray handle, the machine should be started and the quick couplers rinsed.

zAfter detergents are used, the injector system should be flushed with water to avoid clogging the system.

zThe inlet water screen should be cleaned once a month or more frequently as required.

zWe recommend you to store the machine in a frost-free room. If the machine freezes up by mistake, it must not be started. Thaw the machine, hoses and accessories before starting. If the room is not frost-free the machine should be protected with anti-freeze.

See section »3.8 Storage - frost protection«.

zReplace the fuel filter every 6 months, or more frequently as required.

6.2Descaling the coil

If your water supply is “soft” or “normal”, descaling may never be required if you use NoScale. If you have “hard” water, the machine should be descaled at least once the year or more often in extreme cases. Scale deposits in the spray lance or reduced heating output are indications that descaling is required.

Descaling is performed as follows:

1.Detach high pressure hose.

2.Turn on the inlet water.

3.Insert the suction hose for the detergent (12) in a container with descaling acid.

4.Adjust the metering unit to step 5 (see section 3.1.6).

5.Start the machine in cold water mode.

6.Stop the machine when the water escaping the outlet socket has been coloured by the descaler.

Warning: The mixture will be caustic!

Don’t empty the descaler container completely to prevent air from getting into the system.

7.Let the machine stand for 20 minutes.

8.Place the metering unit suction hose (12) in a container of clean water.

9.Start the machine and let it run 5-10 minutes to flush the descaler out of the system.

10.If required, repeat the procedure from item 3-9.

11.Adjust the metering unit to step 0, and the machine is ready for operation.

Note: The descaling should always be carried through in accordance with the product instructions.

6.3 Clearing the high pressure nozzle

A clogged up nozzle causes excessive pump pressure and clearing is required immediately.

1.Stop the machine and detach the spray lance.

2.Clear the nozzle with KEW Technology nozzle clearing tool (no. 6401654), or a straightened paper clip. IMPORTANT: ONLY use the clearing tool with the spray lance detached from the machine!

3.Flush the spray lance backwards with water.

4.Repeat items 1-3 if the pressure is still too high,
