Belt Removal/Installation 

The drive belts can be replaced. When replacing belts, always use the correct belt type

 and replace 

both belts at the same time.

1.  Remove the drive belt cover, as per process described earlier under “Belt tension adjustment”.

2.  Loosen the engine mounting and locating bolts. Back off the rear engine locating bolts sufficiently 

so that the engine can be moved enough to remove/install the belts.

3.  Remove the belt from the drive pulleys.

4.  Ensure the drive pulleys are clean and smooth.

5.  Place the new belt over the pulleys then adjust as described above.

Cleaning Guidelines 

CLEANING WARNINGS: 

-  Do not use solvents, chemicals or abrasives when cleaning the machine, as this may damage 

some surfaces of the chipper
-  Do not use high-pressure sprayers near the blade shaft bearings as bearing damage may result.

-  Wear gloves or use suitable tools to assist in cleaning – do not use bare hands.

-  Clean the machine after every use to ensure best performance and longest service life.

-  Avoid tilting the machine to avoid potential fuel or oil spills or leaks. 

How to clean your chipper:

-  

Use a slightly damp cloth, water and mild detergent for cleaning.

-  Use a brush for parts that are difficult to reach.

-  Ensure air vents and surfaces designed for heat dissipation are free of obstructions or debris.

-  It is recommended to lightly oil the cutting blades after each use to help prevent corrosion.

-  Ensure all chutes and flaps are clean and not obstructed.

-  Ensure that all control cables, levers, switches etc are clean and operate normally and smoothly.

Transportation and Storage

 

Always ensure that the machine is cool enough before transporting or storing. 

Petrol is 

extremely flammable – always keep clear of naked flames or other ignition sources. 

Preparing for Transport and Storage.

Clean the equipment before transport or storage.
Disconnect the spark plug lead.

Store the equipment in a dry, well-ventilated area and out of the reach of children.

Long Term Storage  

Follow the normal procedures for storage, then: 

-  Drain the fuel system. It is advised to have the fuel tank as empty as possible before draining.

 

1.  Unscrew (rotate left) the carburettor drain plug. Use a suitable container to catch the 

draining fuel, and allow the fuel to drain. Store the drained fuel in a properly sealed container.
 

2.  Re-install (rotate right) the carburettor drain plug and tighten.

-  Remove the spark plug and put 30ml of clean engine oil into the cylinder. Pull the starter rope 

slowly to distribute the oil. Re-install the spark plug.
-  Lubricate the blade shaft bearings.

-  Cover the equipment to protect it from dirt and dust.
