Product description
Intended purpose
The CSH24 Chain Saw is designed and built for the following
applications:
• Cutting of concrete (including reinforced), masonry and natural stone
• Cutting of severance cuts, flush cuts and cross-cuts in ceilings, floors
and walls
•Only original Diamond Products Chain should be used
Safety measures
Any use other than for the intended purpose constitutes improper use or
misuse.
Since improper use or misuse can result in considerable danger,
here are some examples of what we believe constitute improper
use or misuse.
The following applications are prohibited:
• Cutting without the safety devices provided
• Cutting wood, glass and plastics
• Cutting without system and tool cooling
• Cutting in explosion-protected areas
• Cutting loose parts
• Incorrect or absence of waste water disposal (saw sludge)
Workplace Safety
Allow enough room for maneuvering toensure danger-free working.
Make sure you have sufficient lighting at your workplace.
Clearly cordon off the danger area so that no person can enter the danger
area during sawing.
The front, underneath and rearof the sawing area must be protected so
that persons or equipment cannot be harmed by falling objects,
concrete slurry, or by the protruding cutting tool.
Secure pieces of concrete that have been loosened to prevent falling.
Breathing in the water vapor that is created is a health hazard.
Ensure adequate ventilation in sealed-off areas.
The slurry resulting from cutting is slippery. Remove the slurry orensure
that you orother people donot slip on it.

Safety instructions
Safety principles
Safety Boundaries
The CSH24 Chain Saw has no effect on the safety concept of the
connected systems, apparatus and installations.
Safety elements
Protection from personal injury is based primarily on a safety concept and
design safety.
Passive safety elements
Protection from live parts
All functional units that contain parts which carry hazardous voltages, are
shock-protected by suitable covers.
Removing protective devices
Protective devices should only be removed when the device is turned off,
disconnected from the mains and at a standstill. Safety components in
particular should only be removed and refitted by authorised personnel.
Before using the CSH24 Chain Saw again, the safety elements must be
checked for correct operation.
Safety measures (organisational)
Product monitoring obligation
Operating personnel must notify changes in the operational behaviour or
safety-related components to a responsible person or the manufacturer
immediately.
Location of Operating instructions
A copy of the Operating instructions must be available at all timesto
staff where the CSH24 is in use.
