4Proprietor responsibilities
For the purposes of the present operating instructions the “proprietor” 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 for
which it is intended and that there is no danger to life and limb of the user and third
parties. Furthermore, accident prevention regulations, safety regulations and
operating, servicing and repair guidelines must be followed. The proprietor must
ensure that all users have read and understood these operating instructions.
NOTE
Failure to comply with the operating instructions shall invalidate the warranty. The
same applies if improper work is carried out on the truck by the customer or third
parties without the permission of the manufacturer.
5Adding attachments and/or accessories
Adding accessories
The mounting or installation of additional equipment which affects or enhances the
performance of the forklift truck requires the written permission of the manufacturer.
Local authority approval may also need to be obtained.
Local authority approval does not however constitute the manufacturer’s approval.

BTruck Description
1Application
The DFG/TFG 316-435 is a four-wheel IC motor sit-down forklift truck. The DFG
series are diesel engine trucks, while the TFG series are fitted with a petrol engine for
LPG operation.
The DFG/TFG 316-435 is a cantilever counterbalanced truck which can lift, transport
and deposit loads using the load handler attached in front.
Closed bottom pallets can also be lifted.
The DFG/TFG 316-435 is equipped with a hydrodynamic drive. The left pedal is a
combination of crawl speed and brake pedal, and activates the rapid lift function
during slow travel. The middle pedal is a standard brake as well as emergency brake
pedal.
1.1Truck models and rated capacity
The rated capacity depends on the model. The rated capacity can be derived from
the model description.

2.2Functional Description
Chassis
The chassis, in conjunction with the counterweight, forms the supporting base
structure of the truck. It is used to support the main components.
The hydraulic oil reservoir is integrated on the right-hand side and the fuel tank for the
DFG series is on the left side in the chassis.
Operator position and overhead guard
The overhead guard (1) comes in a range of models and protects the driver from
falling objects and other external influences.
All the controls are ergonomically arranged. The steering column and driver's seat
can be adjusted individually.
The controls and warnings on the display unit (4) enable the system to be monitored
during operation, thereby ensuring a very high level of safety.
Steering
The steer cylinder of the hydrostatic steering is integrated in the steer axle (11) 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.
Wheels
All wheels are located within the truck geometry. A choice of pneumatic or
superelastic tyres are available.
Engine
High performance, water-cooled diesel and LPG engines with long useful lives and
low consumption and emission levels.
Electrical system
12 volt system with threephase alternator. A start block prevents malfunctions when
the truck is powered up. For diesel engines, a rapid pre-heat system is installed; LPG
motors have an electronic ignition system for rapid and trouble-free engine starting.
The key switch is used to stop the engine.
08.11 EN
17
Drive system
A power shift gear with radiator and torque converter transfers the force to the drive
axle (8).
The travel direction switch on the left hydraulic control lever regulates forward/reverse
travel and the neutral position.
Brakes
The brake pedal actuates two drum brakes which are applied to the drive wheels. An
additional slow travel / brake pedal facilitates creep speed applications. The pedal
should not be used for normal braking purposes. Worn drum brakes are automatically
adjusted. The parking brake operates through mechanical actuation of the parking
brake lever on the drum brake via Bowden cables.
Hydraulic system
A multi-pilot valve allows for sensitive operation of the functions via the controls. A
speed-controlled hydraulic pump ensures a proportionate and efficient supply to the
hydraulic functions.
Mast
Two or three-stage masts, optionally with free lift function; narrow mast sections
ensure excellent visibility of the forks and attachments. Fork carriage and mast run
on permanently lubricated and hence maintenance-free support rollers.
Attachments
The trucks can be optionally fitted with mechanical and hydraulic attachments.
