SCARIFIER MAINTENANCE

12

Keeping Engine Clean

Remove all thatch debris from the engine including the exhaust, 
exhaust guard, the air ways in the top cowl and the surrounding 
deck areas on a daily basis after use. Never spray the engine with 
water during cleaning. Water can contaminate the fuel. Always 
clean with a brush or compressed air. 

(Refer fi g.22)

Thatch debris may clog the engine’s air cooling system 
especially after prolonged operation. The internal cooling fi ns 
and surfaces may require cleaning to prevent overheating and 
engine damage. We recommended that this service be carried 
out by an authorised Briggs and Stratton dealer.

Collector Bag 

Remove thatch debris from the collector bag immediately after 
use and check its condition for signs of damage.

To prevent accidents replace a damaged collector bag 
immediately. 
(Refer fi g.23)

Deck Housing

Remove thatch debris from the top and underside of the deck 
housing immediately after use. 

(Refer fi g.24)

Fertilisers and top dressings are particularly corrosive. 

Thoroughly clean the Scarifi er deck immediately after use 
and store well away from corrosive materials.

Securing Nuts and Bolts

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

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 casting.

Storage

To store the handlebar, unscrew the 2 small securing knobs 
suffi ciently to allow it to be pivoted forwards to rest against 
the Scarifi er. Take care to ensure that the control cables do not 
become snagged at the pivot point and depress the engine stop 
lever to prevent it being damaged through contact with the 
engine spark plug.

(Refer fi g.25)

Engines stored in excess of 30 days need to be protected with 
Briggs & Stratton fuel additive or drained of fuel to prevent gum 
from forming in the fuel system or on essential carburettor parts.  

To ensure your Scarifi er is maintained in good working order it 
is important that the following procedure is adopted.

Drain fuel from the engine by running the engine until it stops.

Disconnect the spark plug lead.

Change the engine oil.

Remove the engine spark plug and pour 15ml of engine oil into 
the cylinder and replace the spark plug. Do not exceed the stated 
volume of oil as engine damage may occur on restarting. Do 
not replace the spark plug lead. Slowly pull the engine start grip 
once to crank the engine. This will distribute the oil and help 
prevent engine corrosion.

Clean thatch and debris from the engine cylinder, cylinder head 
cooling fi ns, under top cowl, around and behind exhaust, exhaust 
guard and ensure that the collector bag is clean.

Lubricate the Scarifi er and treat metal parts with a water repellent 
anti-corrosion product.

Cover the Scarifi er with a protective sheet and store it in a dry, 
ventilated area.
