Especially when using the machine in this configuration for the first time, check to ensure that the
throttle cable is correctly adjusted. When the throttle trigger is pressed fully, the product must run
up to maximum speed. If this is not the case, the throttle cable can be readjusted by way of the
cable tensioner.
When the throttle is not actuated, the engine must be idling and the cut-off wheel must not rotate.
If this is not the case, switch off by pushing the run/stop switch to the "stop" position and then
adjust the throttle cable or have the idling speed adjusted by Hilti Service.
