Determine the best and safest method of operation. • Make the slope as horizontal as possible before continuing opera- tions. • If you need to operate on a street, protect pedestrians and cars by designating a person for worksite traffic duty or by installing fences around the worksite.
• If water lines, gas lines, and high-voltage electrical lines may be buried under the worksite, contact each utility and identify their lo- cations. Be careful not to sever or cut any of these lines. • Check the depth and flow of water before operating in water or crossing a river. NEVER be in water which is in excess of the per- missible water depth. Permissible water depth See n 12.11 “PRECAUTIONS FOR OPERATION.” SAFETY AT WORKSITE FIRE PREVENTION • Thoroughly remove wood chips, leaves, paper and other flamma- ble things accumulated on the engine compartment.
