Cutting Height

CAUTION

:

 

For safety ensure that the Safety Key and Battery are 
removed from the Mower before adjusting the height.

To ensure that the roller is aligned correctly, it is recommended 
that the height is adjusted on a level surface. It is also 
recommended that the Grass Collector be removed as this will 
allow easier access to the Locking Knobs.

1. 

Pull out the knobs on both sides of the roller. (Fig 11)

2. 

Holding both knobs, raise or lower the mower to the 
desired height.

3. 

Allow the knobs to spring into the holes, ensure they sit 
fully into the hole, are at the same height and properly 
secured.

Battery Level Warning

This mower uses sealed Pb lead acid batteries, which like all 
batteries can be damaged if they are over-discharged. The 
electronic circuit will warn of low battery level and RED LED 
will be on, this indicates that the battery should be recharged 
at this point.

GREEN LED ON

–Normal operation.

RED LED ON

–Battery flat, please charge to prevent over 

discharge damage.

Blade Adjustment

SHARP BLADES – BE VERY CAREFUL.  

CAUTION

:

For safety ensure that the Safety Key and Battery are 
removed from the Mower before adjusting the blade.

To adjust the blade turn the 2 bolts on the blade shield. The 
cylinder should almost touch the blade, but do not over  
tighten it. (Fig.13)

 
If the cylinder hits the blade, 
it is too tight and will damage  
the cutting edge; loosen  
the nuts.

To check for correct  
adjustment, insert a piece  
of paper between the blade  
and the cutting cylinder.  
When the cutting cylinder  
is turned by hand the paper  
should be cut cleanly.
