Danger
Risk of injury!

Check the high pressure hose for dam-
ages (risk of bursting).
Please arrange for the immediate ex-
change of a damaged high-pressure hose.
The flow resistance is higher if there are de-
posits in the pipes; this increases the load
on the motor.
ƽ
Danger
Risk of explosion due to combustible gas-
es! Smoking strictly prohibited during de-
calcification. Ensure proper ventilation.
ƽ
Danger
Risk of burns injury on account of acid!
Wear protective glasses and protective
gloves.
According to statutory requirements, only
tested and approv approved boiler decrust-
ing agents may be used.
– RM 100 (Order No. 6.287-008) dis-
solves chalk and simple compounds of
chalk and detergents residues.
– RM 101 (Order No. 6.287-013) dis-
solves the deposits that cannot be dis-
solved using RM 100.
 Fill a 20 litre container with 15 l water.
 Add one litre of boiler decrusting agent.
 Connect the water hose directly to the
pump and hang in the other free end
into the container.
 Insert the connected spray pipe without
nozzle into the container.
 Start the engine according to the oper-
ating instructions of the engine manu-
facturer.
 Open the hand-spray gun and do not

temperature is reached.
 Switch off the appliance and let it stand
for 20 minutes. The hand-spray gun
must remain opened.
 Then pump out the machine until emp-
ty.
Note
As an anti-corrosion measure and for neu-
tralising the acid residue, we recommend
that you finally pump an alkaline solution
through the machine (for e.g. RM 81) via
the detergent tank.
