1.5 RISK ASSESSMENT AND HAZARD MITIGATION
The Globe Valve Grinder was designed and built on the basis of a risk analysis and
under consideration of all relevant harmonised standards as well as further national
standards and technical specifications. The machine thus conforms to the current
level of technology and guarantees the highest possible degree of safety.
This level of safety can only be achieved in practice if all necessary measures are
observed in dealing with the machine. It is therefore part of the duty of care of the
machine's operator to plan these measures and check that they are correctly exe-
cuted.
In particular, the operator must ensure that:
• the Globe Valve Grinder is only used as prescribed (cf. chapter
"Product Description")
• the Globe Valve Grinder is operated only in a fault-free, operational
condition and in particular the safety devices are regularly checked to
ensure that they function as stipulated.
• any necessary protective equipment for the operating, maintenance and
repair personnel is available and is used
• the operating manual is always legible and is available in full at the
Globe Valve Grinder’s location
• the machine is operated, maintained and repaired only by sufficiently
qualified and authorised personnel
• these personnel are regularly instructed in all matters relating to occu-
pational safety and environmental protection and are familiar with the
operating manual and in particular the safety instructions it contains
• all safety instructions and warnings on the Globe Valve Grinder are vis-
ible and legible and are not removed.
Portable Machine Tools are designed for on-site machining applications. They typ-
ically attach directly to the workpiece itself, or to an adjacent structure, and
achieve their rigidity from the structure to which it is attached. The design intent is
that the Portable Machine Tool and the structure to which it is attached become
one complete machine during the material-removal process.
The operator must perform an overall review and on-site risk assessment of the
intended application. Due to the unique nature of portable machining applications,
identifying one or more hazards that must be addressed is typical.
When performing the on-site risk assessment, it is important to consider the Porta-
ble Machine Tool and the workpiece as a whole.

1.6 RISK ASSESSMENT CHECKLIST
The following checklist is not intended to be an all inclusive list of things to watch
out for when setting up and operating this Portable Machine Tool. However, these
checklists are typical of the types of risks the assembler and operator should con-
sider. Use these checklists as part of your risk assessment:
TABLE 1-1. RISK ASSESSMENT CHECKLIST BEFORE SET-UP
Before set-up
I took note of all the warning labels on the machine.
I removed or mitigated all identified risks (such as tripping, cutting, crushing, entan-
glement, shearing, or falling objects).
I considered the need for personnel safety guarding and installed any necessary
guards.
I read the machine assembly instructions (Section 3).
I created a lift plan, including identifying the proper rigging, for each of the setup
lifts required during the setup of the support structure and machine.
I located the fall paths involved in lifting and rigging operations. I have taken pre-
cautions to keep workers away from the identified fall path.
I considered how this machine operates and identified the best placement for the
controls, cabling, and the operator.
I evaluated and mitigated any other potential risks specific to my work area.
TABLE 1-2. RISK ASSESSMENT CHECKLIST AFTER SET-UP
After set-up

I checked that the machine is safely installed (according to Section 3) and the
potential fall path is clear. If the machine is installed at an elevated position, I
checked that the machine is safeguarded against falling.
I identified all possible pinch points, such as those caused by rotating parts, and
informed the affected personnel.
I planned for containment of any chips or swarf produced by the machine.
I followed the required maintenance checklist (Section 5.1).
I checked that all affected personnel have the recommended personal protective
equipment, as well as any site-required or regulatory equipment.
I checked that all affected personnel understand and are clear of the danger zone.
I evaluated and mitigated any other potential risks specific to my work area.

Principle components are shown in
and identified in :
The Globe Valve Grinder is driven
by an electric or a pneumatic
motor, which is mounted to the
upper gear housing. Both drives are
adapted to the machine by means
of a drive flange with clamping
screw. Therefore, depending on the
application, the Globe Valve
Grinder can be delivered with elec-
tric and pneumatic drive unit. The
machine arm connects the gear drive with the machine spindle. During operation,
the machine spindle is rotating. The tools are adapted to the machine spindle by
means of a self-aligning coupling with ball joint. This ensures that the tools are
automatically aligned during machine operation.
An indicator for the grinding pressure is integrated in the upper gear housing.
Planet grinding and lapping wheels (in the following called planet grinding
wheels) are used as tools.
The planet grinding wheels consist of:
• a coupling with ball joint for self-alignment of planet wheels
• a planet wheel
• planet arms with integrated spindle bearing system
• grinding or lapping discs to put onto planet arms
• abrasives for grinding (for lapping operation, a lapping paste is used
instead of abrasives)
Each planet grinding wheel covers a wide working range. To adjust the wheel to
the machining diameter, the planet arms can be moved into the planet wheel
guides. The planet arms are clamped with one screw quick clamping system.
