Deck Housing

Tip  the  mower  onto  it’s  left  hand  side  thus  ensuring  
that  the  air  cleaner  is  kept  uppermost  to  prevent  engine  
damage.  Remove  grass  debris  from  the  top  and  underside  
of  the  deck  housing  immediately  after  use.  

5HIHU¿J

Fertilisers  and  top  dressings  are  particularly  corrosive.  
Thoroughly  clean  the  mower  deck  immediately  after  
use  on  treated  grass  and  store  well  away  from  corrosive  
materials.  

Securing Nuts & Bolts

Regularly  check  that  all  securing  nuts  and  bolts  are  tight.  
Replace  missing  or  damaged  items  immediately.  

Clutch Cable Adjustment

At  any  time  the  operator  feels  that  the  machine  is  loosing  
drive:
1.  Stop  the  engine.
2.  Pull  the  machine  backwards  at  the  same  time  

progressively  engage  the  clutch  lever  until  the  rear  
rollers  lock,  at  this  point  the  clutch  lever  should  be  
60mm  from  the  handlebar.

3.  If  the  distance  between  the  clutch  lever  and  handlebar  

is  less  than  60mm  regulate  the  engagement  position  
with  the  black  plastic  cable  adjuster.  To  regain  the  
60mm  distance

4.  Note  this  is  a  temporary  adjustment  and  at  the  nearest  

   opportunity  a  service  should  be  carried  out  to  ensure  

the  spring  on  the  clutch  cable  attached  to  the  gearbox  
clutch  is  set  correctly.  This  adjustment  should  be  done  
using  the  metal  adjuster  at  the  control  with  the  plastic  
adjuster  reset  fully  wound  in.  When  the  spring  is  set  
tighten  the  inner  lock  nut  to  secure  position.

Lubrication

Lubricate  the  wheels,  pivot  points  and  linkages  with  
engine  oil  every  25  operating  hours.
Apply  a  good  quality  medium  grease  to  the  inner  control  
cables  at  the  point  of  entry  and  exit  from  their  outer  cas-­
ing.

Cutterblade Removal

Drain  the  fuel  by  running  the  engine  until  the  fuel  tank  
is  empty  and  the  engine  stops.  Remove  the  spark  plug  
lead  and  allow  the  engine  to  cool.  Turn  the  mower  on  its  
left  hand  side  and  ensure  that  the  air  cleaner  side  of  the  
engine  is  uppermost.  

5HIHU¿J

Firmly  grip  the  end  of  the  cutterblade  with  a  gloved  hand  
and  remove  the  bolt,  spring  washer  and  distance  piece

The  condition  of  the  cutterblade  and  its  mounting  
arrangement  should  be  checked  regularly  for  signs  of  
wear  or  damage.  Ensure  that  the  cutterblade  is  not  bent  
or  cracked.

A  damaged  cutterblade  that  is  out  of  balance  will  vibrate  
excessively  and  may  break.  DO  NOT  use  an  unbalanced  
cutterblade.

Regularly  check  that  the  bolt  securing  the  cutterblade  is

Replace  the  cutterblade  every  2  years  of  sooner  if  
excessively  worn  or  damaged.

To  prevent  injury  it  is  wise  to  seek  assistance  when  
turning  the  mower  on  its  side.
