If the product and supplied accessories are used for
other purposes than the intended purpose, it is the
responsibility of the user to check the suitability and
admissibility. Product use not confirmed in writing
by the manufacturer absolves the manufacturer of
any liability.
The manufacturer is not liable for consequences of
incorrect treatment, use, maintenance, servicing
and operation of the appliance, as well as normal
wear and tear. The same applies if faults arise from
modifications or configurations on the part of the
user not authorized by the manufacturer.
Prevention of obvious
misapplication (examples)
• Motor may only be operated with correctly
mounted pump tube.
• Motor may only be used in permissible explo-
sion hazard area
• Use suitable compressed air supply
• Do not connect the compressed air supply
while the engine is switched on
• Do not immerse the motor in the liquid being
pumped
• Do not drive inadmissible devices with the
motor
• Do not allow the motor to be operated by
children or people in need of protection
• Do not use improper accessories
• Do not use improper or inadmissible spare
parts
• Observe maintenance intervals

DANGER
Danger of explosion from use in an explosion
hazard area!
When pumping flammable liquids, the operational
safety regulation and the following points have to
be observed:
• Compressed air motors are non-electrical oper-
ating appliances not requiring official approval
when used in zone 1.
• The motors are therefore suitable for driving
explosion proof Lutz drum- and container pumps
Class I, Group D and C.
• Application restrictions are depending on the
respective pump tube (
→
operating instructions
pump tube).
• Only authorized for mobile use.
• Connect equipotential bonding (
→
chapter 9).
• Use conductive pressure hoses only (
→
operating
instructions pump tube).
• The pump motor must remain outside the drum
or container.
• Operating pressure must not exceed 72,5 psi
(5 bar).
• The temperature of the compressed air supplied
must not exceed the max. permissible ambient
temperature.
• Motor and pump tube operation must be con-
trolled.
• Do not operate the motor with flammable gases.
• Prescribed inspection periods: Grooved ball
bearing and vane, both have to be exchanged
at latest after 1.000 operating hours.
• The presence of strong charge-generating
processes, in particular the arrangement within
transported dust and within a distance of 1 m
from high-voltage electrodes, must be excluded.
