The operating instructions must be read and used by all persons entrusted with working on the
grinding machine, e.g. those entrusted with:
• transportation, installation, commissioning
• operation, including fault elimination in the process flow
• servicing (maintenance, repair)
In addition to the operating instructions and the binding accident prevention regulations applicable in the country and place in which the machine is used, generally acknowledged technological
rules with regard to safe and professional work practices are to be observed.
1.2 Warnings and symbols in the operating instructions
It is essential to observe the following symbols / designations used in the operating instructions.
The hazard triangle with the signal word “CAUTION” is used as a work
safety indication for all work which might result in death or physical injury.
Special care and caution must be taken when carrying out such work.

1.3 Warning signs and what they mean
1.3.1 Warning and prohibition signs on the grinding machine
The following warning and prohibition signs have been affixed to the grinding machine:
CAUTION! DANGEROUS ELECTRICAL VOLTAGE
(warning notice on the control panel)
When connected to the voltage supply (3x 400 V), the grinding
machine becomes electrically live and touching its live parts directly
can be life-threatening.
Live machine parts may be opened only by authorized, trained
personnel.
The grinding machine must be disconnected from the mains supply
before carrying out servicing, maintenance and repair work on it.
CAUTION! RISK OF INJURY FROM KNIFE
(prohibition sign on the base plate)
Work on the grinding machine involves grinding knives which
could cause serious cut injuries due to the sharp blades.
Wearing protective gloves is mandatory when carrying out such
jobs.
Be careful when transporting blades! Use the protective devices
provided by the knife manufacturer. Wear protective gloves and
apron.
1.3.2 General prohibitions signs
The following general mandatory signs must be observed:
CAUTION! RISK OF INJURY DUE FROM ABRASIVE PARTICLES
DURING DRESSING
Dressing the grinding wheel gives rise to abrasive particles which
can enter the eyes.
Wearing safety glasses is mandatory when carrying out such jobs.

• operating the grinding machine with defective safety devices, or using improperly attached or
malfunctioning safety and protective equipment
• failure to observe the instructions with regard to transportation, commissioning, operation,
maintenance and repair of the grinding machine
12
• unauthorized structural alterations to the grinding machine
• unauthorized modification of such aspects as drive conditions (power and speed)
• insufficient monitoring of machine parts that are exposed to wear
• use of unapproved replacement and wear parts
Page 12
2. Safety
Use only original replacement and wear parts. If parts are purchased from external suppliers, there
is no guarantee that they are designed and manufactured to withstand the required level of stress
and provide the required level of safety.
2.4 Safety regulations
2.4.1 Organizational measures
All available safety devices must be checked regularly.
Observe prescribed intervals for recurring maintenance work or as specified in the operating

devices at least once every shift.
Report any changes (including operating behavior) immediately to the department / person
in charge. Where required, shut down the grinding machine immediately and secure against
restarting.
Before switching on the grinding machine, ensure that no one is exposed to any risk from the
start-up of the machine.
If there are any functional faults, stop the machine immediately and secure against restarting.
Have the faults eliminated immediately.
2.4.7 Hazards due to electrical power sources
The switch cabinet must always remain secured against access. Only authorized personnel must
be allowed to access it.
Work on electrical units or operating materials may only be performed by a qualified electrician in
accordance with electrical rules.

For all work on the grinding machine, the locally applicable safety and
accident prevention regulations as well as instructions in the “Safety”
and “Important Notes” section of the operating instructions must be
observed.
CAUTION

The water trough must always be filled with water
up to 3 cm below the rim. The water trough can
be pulled out in front for filling and cleaning.
The pump (9-1/1) including the guard can be
2
removed by loosening and removing the star handles (9-1/2).
Place grease gun on the lubrication points and
lubricate the cross table.
We recommend “OEST Multi-Purpose Grease L2”
or a similar commonly available product.
Press one round of grease into the lubrication
point using the grease gun once a month.
