3.2.11  When travelling, the hydraulic pump should be switched off. 

 

 

IMPORTANT

 

When moving or working on public roads, the relevant traffic rules and 
regulations must be adhered to.

  

 

3.3    Transport Position for Travelling Long Distances (without tree) 

 

The circular digging head frame is collapsible. When travelling long distances or when 
being transported on a low bed loader on public roads, the frame can be folded up, thus 
reducing the transport height (see illustration 5).

To get tree spade Optimal 2500 into the transport position as shown above, the following 
work must be performed: 
 

Retract all spades to top position 

(spades “

up

”) and get digging head in vertical 

position just above the ground. 

Unlock gate lock 

Open RH gate and LH gate 

Release snap-on pin (B) and remove stop pin (A) at both sides of the circular frame of 
the digging head (ill. 6) 

Put stop pin at depository position (C) as shown on illustration 7. 

First close the RH gate and then the LH gate completely 

Install stop pin (A) of LH gate as transport lock as shown on illustration 8.
