Jungheinrich TFG 660 Workshop Manual
The present ORIGINAL OPERATING INSTRUCTIONS are designed to provide sufficient instruction for the safe operation of the industrial truck. The information is provided clearly and concisely. The chapters are arranged by letter and the pages are numbered continuously. The operator manual details different industrial truck models. When operating and servicing the industrial truck, make sure that the particular section applies to your truck model.
Our trucks are subject to ongoing development. Jungheinrich reserves the right to alter the design, equipment and technical features of the system. No guarantee of particular features of the truck should therefore be assumed from the present operating instructions.
Jungheinrich TFG 660 Operator Manual
For the purposes of the present operating instructions the “operating company” is defined as any natural or legal person who either uses the industrial truck himself, or on whose behalf it is used. In special cases (e.g. leasing or renting) the proprietor is considered the person who, in accordance with existing contractual agreements between the owner and user of the industrial truck, is charged with operational duties. The proprietor must ensure that the industrial truck is used only for the purpose it is intended for and that danger to life and limb of the user and third parties are excluded. Furthermore, accident prevention regulations, safety regulations and operating, servicing and repair guidelines must be followed. The operating company must ensure that all users have read and understood these operating instructions.
Jungheinrich TFG 660 Chassis and superstructure
A rigid chassis which protects the units and controls, provides the truck with maximum static safety. A wide opening cab (5) facilitates service and maintenance work. The hydraulic oil reservoir is integrated on the right-hand side and the fuel tank on the opposite side of the chassis. The vertical, free standing front exhaust pipe (8) is positioned much higher than is common. It prevents vibrations and sound saves from being transferred and exhaust gases from penetrating into the operator position.
Jungheinrich TFG 660 Operator position
The operator position is articulating, which cushions vibrations and noise. Non-slip steps and a handle on the cab post ensure easy entry and exit. The driver is protected by the cab (5). To adapt the seat position, the driver can adjust the seat and steering head both vertically and horizontally. The accelerator pedal and brake pedal are of "automotive" design.
Steering
The steer cylinder of the hydrostatic steering is integrated in the steer axle (9) and is controlled by the power steering. The steer axle is fully floating in the chassis to ensure excellent grip even on non-level surfaces.
Jungheinrich TFG 660 Diesel engine
Quiet-running, water-cooled diesel engines featuring high performance and low consumption with very clean fuel combustion under all operating conditions ensure soot values are below the limit of visibility. An additional particle filter (o) ensures very low exhaust levels.
