MAINTENANCE
ATTENTION! It is imperative that the machine be
deenergized by unplugging the plug before all
work and maintenance work. Otherwise there is
a danger of short-circuiting!
Repairs may only be carried out by qualified
personnel who dispose the corresponding
training and experience. The device must be
tested by a skilled electrician after every repair.
The mortar spraying machine is designed so that a minimum of
care and maintenance is required. However, the following work
has to be carried out and components checked regularly:
9.1
MECHANICAL MAINTENANCE
•
Keep the thread at the pump tube and pump housing
clean and, if appropriate, seal.
•
Check the seals at all the couplings and connecting pieces
for leaks. If appropriate, replace worn seals.
•
Check the following for damage before every usage:
- Mortar hose
- Power cable
- Control unit
9.2
ELECTRICAL MAINTENANCE
•
The electrical drive and its ventilation slots must always be
kept clean and may not be cleaned with water. Danger of
short-circuits.
9.3
LONG PERIODS OF NON-USAGE
If the mortar spraying machine is not used for a longer period, it
has to be cleaned thoroughly and protected against corrosion.
i
Take the stator out of the pump unit so that it
cannot get stuck to the rotor.

SHAFT SEAL (FIG. 16)
i
Check the seals on the PowrMax 605 every
month.
1. Move selector switch (fig. 16, 1) to “A” and set delivery
