Troubleshooting - Ferm GRM1008 Gebrauchsanweisung

4. USE
The cleaner must only be used with clean water;
use of unfiltered water or corrosive chemicals will
damage the cleaner.
• Turn the motor switch to the "0" position.
• Check that the electrical supply voltage and
frequency (Volts/Hz) correspond to those specified
on the cleaner data plate.
• If the power supply is correct, you may now plug in
the cleaner.
• The electric supply connection shall be made by a
qualified electrician. It is recommended that the
electric supply to this appliance should include either
a residual current device that will interrupt the
supply if the leakage current to earth exceeds 30 mA
for 30 ms or a device which will prove the earth
circuit.
The machine may cause electrical disturbances
when starting.
If the motor stops and fails to restart, wait 2-3 minutes
before restarting. THERMAL CUTOUT TRIPPED
ADJUSTING THE NOZZLE
Fig. 3
Water may be sprayed out of the nozzle either linearly
or in a fan shape. Turn on the pressure first, and then
adjust the nozzle.
The water inlet filter must be inspected regularly, so as
to avoid blockage and restriction of the water supply to
the pump. (Fig 4)
USING THE DETERGENT RESERVOIR
Fill the detergent tank with liquid detergent. When the
trigger is now pressed with the machine running,
detergent will spray out with the water.
RECOMMENDED CLEANING PROCEDURE
Dissolve dirt by applying detergent with the fan jet to the
dry surface. On vertical surfaces, work from the bottom
upwards. Leave the detergent to act for 1 to 2 minutes,
but do not allow to dry out. Apply the high pressure jet,
keeping the nozzle at least 30 cm (10 in.) from the
surface, working from the bottom upwards. Avoid
allowing the rinsing water to run on to unwashed
surfaces.
SHUTTING DOWN THE PRESSURE
WASHER
Never disconnect the high- pressure hose from the
machine while the system is still pressurized.
Follow the correct procedure:
1. Turn off the pressure washer by using the switch on
the machine.
2. Unplug the unit from the power source.
3. Turn off the water supply at the tap.
4. Press the trigger of the gun to depressurize the
6
system.
5. Disconnect the supply hose to the machine
6. Wipe all surfaces of the unit with a damp clean cloth.
7. Engage the safety lock.

TROUBLESHOOTING

1. When switched on, the machine will not start
working.
• Plug is not well connected or electric socket is faulty
- Check plug, socket and fuse.
• The mains voltage is lower than the minimum
requirement for start up
- Check that the mains voltage is adequate.
• The pump is stuck
-- Refer to after storage instructions
-- Switch off the unit and let the motor cool.
• Thermal safety has tripped
- Leave the lance open with water coming through.
2. Fluctuating pressure
• Pump sucking air
- Check that hoses and connections are airtight.
• Valves dirty, worn out or stuck. Pump seals worn
- Clean and replace or refer to dealer.
3. Water leaking from the pump
• Seals worn out
- Check and replace, or refer to dealer
4. The motor stops suddenly
• Thermal safety switch has tripped due to
overheating.
- Check that the mains voltage corresponds to
specifications. An extension cable, which is too thin,
and tool long can cause a voltage drop and cause the
motor to overheat. Leave to cool down. Use heavy
duty extension cables.
5. The pump does not reach the necessary
pressure.
• Water inlet, filter is clogged
- Clean the water inlet filter
• Pump sucking air from connections or hoses
- Check that all supply connections are tight
• Suction/ delivery valves are clogged or worn out.
- Check that the water feeding hose is not leaking.
• Unloader valve is stuck
- Clear or respire valves
• Lance nozzle incorrect or worn out
- Loosen and re-tighten regulation screw.
- Check and/ or replace.
