Insert the chain correctly according to the engraved mark. Failure to comply with this regulation may lead to serious physical injury or death. Function The diamond chain constitutes the tool for the CSH24 Chain Saw. It is with the help of the chain that the cut is performed.
CSH24 Chain Saw Front handle The front handle is used to hold and carry the CSH24 Chain Saw. Operating handle with manual starter The operating handle with manual starter is secured by the locking cut-out against unintentional activation.
Danger Danger from machine suddenly starting up. Before switching on the CSH24 Chain Saw the operator must ensure that no other person is present in the danger areas. Failure to observe this regulation may lead to serious physical injury, property damage, and possibly even death.
Page 23
Danger Danger from uncontrolled movements When the CSH24 Chain Saw is switched on, always hold it with both hands using the handles. Thumbs and fingers must be closed around the handles. Otherwise you may loose control of the Chain Saw. Handles must always be clean and dry.
Page 24
Failure to observe this regulation may lead to serious injury to body parts, and possibly even death. Danger Danger of the CSH24 Chain Saw restarting in the event of an accident Ensure that you can quickly stop the CSH24 Chain Saw (see Emergency Stop in the Operating instructions of the drive assembly you are using).
Page 25
Warning Warning against working when not in a fit state to do so. Do not use the CSH24 Chain Saw if you are under the influence of sedatives, alcohol or if you are overtired. Failure to adhere to this regulation may result in personal injury.
Operation System requirements In order to use the CSH24 Chain Saw, a hydraulic drive assembly is needed. Drive assembly power requirements: Minimum flow 9.25 gpm Minimum power: Max. pressure 2,000 psi Maximum flow 12gpm Maximum power: Max. pressure 2,000 psi If the basic power of the drive assembly used is higher, a flow divider / pressure limiter or a pressure relief valve can be used.

Operation Sawing Conditions • Determine the position of pipes and cables in walls, floors and ceilings. • Where does the cooling water used for sawing flow to? (Think about water damage to the electrical supply). Securing the site • See “Chapter 1” Workplace and danger areas. Securing cutouts Secure cutouts from walls and especially from ceilings and floors by suitable means, e.g.
