Doosan DX220A DX225LCA — Before Operating Machine

Check gauges and monitor displays for normal operation before starting the engine. Listen for unusual noises and remain alert for other potentially hazardous conditions at the start of the work cycle. Do not short-circuit the starting motor to start the engine. This is not only dangerous, but may also damage the machine. When starting the engine, sound the horn as an alert. Start and operate the machine only while seated. Before Operating Machine If checks are not carried out properly after starting the engine, it may result in a delay in discovering abnormalities in the machine, and this may lead to personal injury or damage to the machine.

Carry out the checks in an open area where there are no obstructions. Do not let anyone near the machine when carrying out the checks. Check the operating condition of the equipment, and the movement of the bucket, arm, boom, travel, and swing systems. Check the machine for any abnormal noise, vibration, heat, smell, or abnormality with the gauges. Check also for leakage of air, oil, and fuel. If any abnormality is found, repair the problem immediately. If the machine is used without repairing the problems, it may lead to unexpected injury or failure. Clear all personnel from directly around machine and from the area. Clear all obstacles from the machine's path. Beware of hazards.

Be sure that all windows are clean. Secure the doors and the windows in the open position or in the shut position. Adjust the rearview mirrors for best visibility close to the machine. Make sure that horn, the travel alarm (if equipped), and all other warning devices are working properly. Fasten the seat belt securely. Warm up the engine and hydraulic oil before operating machine. Before moving the machine, check undercarriage position. The normal travel position is with idler wheels to the front under the cabin and the drive sprockets to the rear. When the undercarriage is in the reversed position, the travel controls must be operated in opposite directions. OP001759 Safety 1-26
