Optimal forward working speed 3-8 km/h                     Raise the machine before turning or reversing      

Operation 

 

Ensure that  the operator is suitably qualified to use a machine of this nature 
and  that  they  have  fully  read  and  understood  this  manual  -  they  should  be 
aware  of  all  safety  aspects  relating  to  the  safe  use  of  the  machine.  It  is 
advisable  that  all  ‘first  time’  operators  practice  using  the  machine  in  a  clear 
safe area prior to work in order to familiarise themselves with its operation. 

After  the  initial  first  1  hour  of  work  with  a  new  machine,  nuts  and  bolts  should  be 
checked for tightness and the drive belts inspected and re-tensioned if required 

– refer 

to belt section for details. 

 

Prior to starting work the area should be checked for dangerous objects such 
as  large  stones,  wood,  wire,  glass  etc. 

–  hazardous  objects  should  be 

removed  from  the  area  prior  to  operation  with  the  machine.  The  location  of 
unmovable  or  natural  hazards  should  be  noted,  or  if  necessary  ‘marked’,  to 
indicate  to  the  operator  that  the  area  should  either  be  avoided  or  additional 
caution adopted whilst working around the hazard. 

 

Starting Work 
 

With  the  machine  switched  off,  lower  it  into  a  position  approximately  10cm 
above  the  ground,  start  the  machine  and  allow  it  to  build  up  to  the  correct 
working speed before gently lowering the it onto the ground  - the machine is 
now in its work position and forward travel can begin. 

 

Forward Speed 
 

The forward working speed will depend on the working conditions and nature 
of the material being cut. Optimal speed will be in the region of 3-8 km/h 

(2-5 

mph). 
 

 
 

Reversing & Turning 
 

When reversing or turning the unit the machine must always be lifted clear of 
the ground to avoid damage.
