Introduction
Thank you for choosing to purchase this quality product. To minimise the risk of injury, we ask you to
always take some basic safety precautions when using this product. Please read this operating manual
carefully and make sure that you understand it.
Keep these operation instructions in a safe place.
Safety instructions
•
Be particularly careful when opening the radiator. It can be pressurised, hot cooling agent might
be ejected.
•
Before demounting the pump or adaptor, depressurise.
•
After testing the pressure or repairing, check the cooling agent to know if it is at a correct level
and if there is enough antifreeze left.
•
Take special care when working on a running engine. Loose or sack-like clothes might be
caught in rotating parts of the engine.
Operation
Radiator leakage test
1.
Remove the original radiator cap from the radiator or compensation tank.
2. Choose the appropriate adaptor from the set, then connect it to the radiator or compensation
tank.
3. Now connect the hand pump to the adaptor (Fig. 1).
4. Press the test pump until a pressure of 0.68 to 1.03 bar (10–15 psi) is achieved (see Figg. 1 and
2).

Radiator-cap leakage test
1.
Remove the original radiator cap.
2. Choose one of the suitable adaptors 2a or 2b, then connect it to the radiator cap.
3. Press the test pump several times and observe the pressure gauge. If the pressure drops, the
cap is defective (see Fig. 3).
4. Compare the pressure values displayed with the standard pressure value of the radiator cap.
Maintenance and storage
•
Plug the test adaptor several times onto the quick coupling of the hand pump to press out the
water remaining inside.
•
Fill pneumatic oil into the air hole of the end of the hand pump to lubricate the piston of the hand
pump.
