Slopes 

To prevent engine damage, do not use the Scarifi er on slopes 
greater than 20 degrees. 

(Refer fi g.11)

Knife Blade Adjustment

To adjust the knife blade depth, grip the lever and pull sideways 
to disengage it from the locking notch. Push forwards to lower 
or pull backwards to raise the scarifying depth. Finally release 
the lever at the required position and ensure it locks fi rmly into 
one of the six setting notches.

Always select a depth to suit operating conditions. Aim to 
prevent engine overload and blockages by being prepared to 
make two height adjustments.

Position 1: Blades completely lifted for moving the machine and 
for starting.
Position 2 to 6: Work positions - cutting depth increases by 
about 5 mm for each position. 

(Refer fi g.12)

Before Scarifying 

To prevent accidents, thoroughly inspect the area and 
remove all objects which when contacted by the Scarifi er 

knife blade could become dangerous projectiles. Inspect the 
area for hidden obstructions which when contacted by the 
knife blade could risk health and safety or result in damage 
to the Scarifi er. Remember the location of these obstructions 
and ensure that you scarify around them. 
(Refer fi g.13)

Collector Bag

Raise the rear defl ector, lift the collector bag through the 
handlebar and hook into position. Lower the rear defl ector  to 
rest against the rear of the Scarifi er. 

To empty the collector bag, empty the thatch and shake the 
collector bag vigorously to clean the airways. Good thatch 
collection depends on good air fl ow through the collector bag. 
When collecting thatch it is important that the collector bag is 
emptied regularly to prevent blockages and engine overloading. 

(Refer fi g.14)

Without Collector Bag

Remove the collector bag and operate the Scarifi er with the rear 
defl ector in the closed position.

(Refer fi g.15)

Non Grassed Areas

When moving the Scarifi er across non-grassed areas, stop the 
engine and set the knife blade height to the highest position to 

protect the cutting mechanism. 

Always stop the engine when a hidden obstruction or 
excessive vibration is encountered. Disconnect the spark 
plug lead and examine the cutting mechanism. ALWAYS 
replace a damaged knife blade. Refer to Maintenance.
