Some noise exposure from this machine is unavoidable.
Schedule noisy work to times during which it is allowed. Respect all
rest times and restrict the work duration to the minimum. You as the
operator and bystanders should wear a suited hearing protection.

Vibrations

Vibration level: = 3.52 m/s²
Measuring uncertainty : K=1.5
The indicated vibration emission level has been measured
according to a standardised test method and can be used to
compare power tools.
It can also be used for an initial estimate of the vibration
exposure.
The actual vibration emission level during the use of the
machine may differ from that indicated in the operating
instructions or indicated by the manufacturer.
This may be caused by the following factors to be minded
before and during the use
- Proper use of the machine
- Correct cutting or machining of material
- Proper condition of the machine for use
- Use of the correct and sharp cutting tool
- Handles and optional anti-vibration handles properly
mounted on the machine body
When you feel uncomfortable or notice discoloration of skin on
your hands during the use of the machine, stop working
immediately. Observe sufficient break times to rest. Failure to
have sufficient break times may result in a hand-arm vibration
syndrome.
The extent of exposure depending on the type of work or
machine use should be estimated and appropriate breaks
taken. In this way, the extent of exposure can be considerably
reduced over the entire work time. Minimise the risk caused by
vibrations. Maintain this machine according to the instructions
in the manual. If you intend to use this machine frequently,
contact your local authorised dealer and purchase anti-
vibration accessories if required. Avoid the use of this machine
at temperatures under 10°C. Create a work schedule in order
to minimise vibration exposure.

Proper use

The chain sharpener is only intended for use in household
and hobby area. In the standard version with mounted
grinding wheel (100 x 3.2 x 10 mm, 63 m/s), the chain
sharpener is only intended to sharpen chains used in
hobby applications (6.35 mm (1/4"), 9.52 mm (3/8")
hobby and 8.255 mm (0.325") chains).
An optional grinding wheel (100 x 4.5 x 10 mm) is available
for professional cutting chains.
The device may not be used to sharpen other objects.
Otherwise, there is a risk of injury.
Use only grinding wheels suitable for the machine.
Only chains may be worked that can be put down and
guided securely.
The intended usage also includes compliance with the
operating, servicing and repair conditions prescribed by
the manufacturer and following the safety instructions
included in the instructions.
The relevant accident prevention regulations for the
operation as well as the other generally acknowledged
occupational medicine and safety rules must be complied
with.
Any other use is deemed not to be use as prescribed. The
manufacturer is not liable for any type of damage resulting
from this: the user bears the sole risk.
Arbitrary modifications of the chain sharpener void the
liability of the manufacturer for damages of all kinds
resulting from them.
Only persons familiar with the chain sharpener and
instructed about possible risks are allowed to prepare,
operate and service this device. Repair work may only be
performed by us or authorized service agencies.
The machine may not be used in a potentially explosive
environment or be exposed to the rain.

Residual risks

Even if used properly, residual risks can exist even if the
relevant safety regulations are complied with due to the design
determined by the intended purpose.
Residual risks can be minimised if the "Safety information" and
the "Intended usage" as well as the whole of the operating
instructions are observed.
Observing these instructions, and taking proper care, will
reduce the risk of personal injury or damage to the equipment.
Risk of injury to fingers and hands by touching the running
grinding wheel.
Risk of injury to fingers and hands by touching the grinding
wheel in areas not covered.
Risk of injury by flying sparks.
Inhalation of grinding dust.
Danger resulting from electric current, if improper
connecting wires are used.
Touching live parts of opened electrical components.
Impairment of hearing when working on the machine for
longer periods of time without ear protection.
In addition, in spite of all the precautionary measures taken,
non-obvious residual risks can still exist.
