Braking
- Take your foot off the accelerator pedal (22).
- Depress the brake pedal (21).
Slow travel with the slow travel / brake pedal
Sensitive application of the slow travel / brake pedal (29) allows for excellent shunting
in confined areas and rapid lifting at a slow travel speed.
The slow travel / brake pedal can also actuate the drum brakes but this is only
intended as a crawl speed aid. The pedal should not be used for normal braking
purposes
M
This operating mode can only be used for max. 5 seconds when the engine is
running at high speed.
o
Speed reduction
Speed reduction restricts the maximum speed to a predefined level. For example,
it could be set to the maximum speed permissible on the company premises. At first,
the full engine speed and performance are available when the truck is in idle and
accelerating. When a certain speed threshold is exceeded the engine speed is
brought back to the required level.
The maximum speed is factory set and can be adjusted by trained and authorised
customer service personnel.
o
Reversing Block
The reversing block reduces the stress and hence wear on the powertrain and
the tyres. Two functions are essentially fulfilled:
The travel direction can only be changed (reversing) if the lift truck is travelling at less
than 3 km/h. If the driver attempts to change direction without braking at a faster
speed, the system automatically activates idle speed. The required travel level can
only be applied when the speed is reduced accordingly.
The drive cannot be set from neutral to travel if the engine is more than 300 rpm
above idle speed. Travel is only activated when the speed falls below this limit.
