• Clean the work area and machine.
• Park the machine on a firm and level ground, and set the parking brake.
• Lower the implement to the ground.
• Stop the engine, and remove the key.
• Disconnect the battery negative cable.
• Hang a “DO NOT OPERATE” tag in operator station.
CSAFETY STARTING
• Do not start the engine by shorting across starter terminals or bypassing the safety start switch.
• Do not alter or remove any part of machine safety system.
• Before starting the engine, make sure that all shift levers are in neutral positions or in disengaged positions.
• Never start the engine while standing on ground. Start the engine only from operator's seat.
SAFETY WORKING

[ex.: Model Name V3300-E2]
The emission controls that have been put into effect in various countries to prevent air pollution will be stepped up. The time to enforce the regulations differs depending on the engine output classifications.
Kubota has been supplying the diesel engines conforming to the emission regulations in respective countries. Exhaust emissions regulations shift to the second stage. Kubota executed the improvement of the engine according to this regulation.
In order to discriminate the engines conforming to Tier 1 / Phase 1 requirements and those conforming to Tier 2 / Phase 2 requirements, we have adopted E2 as a new model name for the engines conforming Tier 2 / Phase 2 regulations with emission label (1) or (2).
In the after-sale services for V3300-E2, V3300-TE2 and V3300TIE2 series engines, only use the dedicated parts for E2 models and carry out the maintenance services accordingly.
