3.4. Storage and transport
Empty the electric pressure test pump and hoses completely to avoid damage.
Store the electric pressure test pump at ≥ 5°C and dry.
4. Maintenance
Notwithstanding the maintenance described below, it is recommended to send
in the electrical device to an authorised ROLLER contract customer service
workshop for inspection and periodic testing of electrical devices at least once
a year. In Germany, such periodic testing of electrical devices should be
performed in accordance with DIN VDE 0701-0702 and also prescribed for
mobile electrical equipment according to the accident prevention rules DGUV,
regulation 3 "Electrical Systems and Equipment". In addition, the respective
national safety provisions, rules and regulations valid for the application site
must be considered and observed.
4.1. Maintenance
WARNING
WARNING
Pull out the mains plug before inspection!
Open the "Test" shutoff valve (7) and "Pressure" regulating valve (8) to release
pressure. The residual pressure could otherwise cause injury to the user by
fl ying parts during disassembly. Observe the pressure gauge (9).
Clean the electric pressure testing pump regularly, especially when it has not
been used for long periods of time. Store the electric pressure testing pump
free from frost. To clean the suction fi lter (4) and the suction fi lter with check
valve (10), unscrew the suction hose, pull the suction fi lter (4) out of the hose
with a suitable tool, e.g. fl at pliers, and clean both fi lters under running water.
Replace damaged suction fi lters. Check high-pressure hose and suction hose
for damage every time before using. Do no used damaged hoses.
Clean plastic parts (e.g. housing) only with machine cleaner (Art. No. 140119)
or a mild soap and a damp cloth. Do not use household cleaners. These often
contain chemicals which can damage the plastic parts. Never use petrol,
turpentine, thinner or similar products for cleaning.
Make sure that liquids can get onto or inside of the electric pressure testing
pump. Never immerse the pressure testing pump in liquids.
4.2. Inspection / Maintenance
WARNING
WARNING
Pull out the mains plug before carrying out maintenance or repair work!
This work may only be performed by qualifi ed personnel.
Open the "Test" shutoff valve (7) and "Pressure" regulating valve (8) to release
pressure. The residual pressure could otherwise cause injury to the user by
fl ying parts during disassembly. Observe the pressure gauge (9).
If the pump loses grease, the complete pressure test pump must be sent to an
authorised ROLLER Customer Service Workshop for inspection and repair.

5. Faults
WARNING
WARNING
To clear faults, switch off the electric pressure test pump at the On/Off switch (1) and pull out the mains plug!
5.1. Fault: Pressure test pump running but builds up no pressure.
Cause:
Remedy:
● "Pressure" regulating valve (8) is open.
● Set the desired pressure by turning the "Pressure" regulating valve (8) to the
right.
● Pressure test pump sucks in air.
● Check whether the suction fi lter with check valve (10) is immersed completely
in the water. Seal screw connections.
● Suction fi lter (4) and/or suction fi lter with check valve (10) on the suction
hose are blocked.
● Clean or replace the suction fi lter (4) and/or suction fi lter with check valve (10).
● Electric pressure test pump defective.
● Have the electric pressure test pump inspected by an authorised ROLLER
Customer Service Workshop.
5.2. Fault: Pressure on the pressure gauge (9) fl uctuates irregularly.
Cause:
Remedy:
● Air in the pipe system.
● Vent the pipe system.
5.3. Fault: Motor does not start, hums.
Cause:
Remedy:
● Electric pressure test pump blocked.
● "Pressure" regulating valve (8) is set to high or max. pressure, open by turning
to left or have the electric pressure test pump inspected by an authorised
ROLLER Customer Service Workshop.
● Unsuitable voltage supply.
● Have the voltage supply tested.
● Unsuitable extension lead.
● Use approved extension lead.
● Pressure is applied in the pump with closed "Test" shutoff valve (7).
● Open "Test" shutoff valve (7).
5.4. Fault: Motor stops suddenly during operation.
Cause:
Remedy:
● Motor circuit breaker has tripped.
● Switch off electric pressure test pump at the On/Off switch (1) and allow to cool
down for approx. 30 minutes.
● Pump run hot or blocked.
● Switch off electric pressure test pump at the On/Off switch (1) and allow to cool
down for approx. 30 minutes or have the electric pressure test pump inspected
by an authorised ROLLER Customer Service Workshop.
