Working with the machine

Note! If the machine is used frequently or for long periods for hammer work, the hydraulic oil will be more contaminated than in usual conditions. Adapt the maintenance intervals for hydraulic oil and for return filter cartridges to the work in heavy dust conditions.

3.4.10

Commutation of control for an additional attachment (option) Danger! Risk of accident due to an unintentional movement by an uninformed machine operator! When the commutation of the control is turned on, the correspondence between the controls and the working movements is changed. When the key is removed from the switch or when the touch is gone out, the machine can be operated only with the usual control system, installed at machine delivery. It is the responsibility of the owner of the machine to grant an operator authorization to operate the machine with the activated special control system. Caution! Check out the functions of the additional controls when starting the machine, especially when a commutation of control is activated.
