Forest Master Model: FM6DD/FM4DDE

•  If the machine starts to make an unusual noise or vibrate, shut down the engine, 

disconnect the spark plug wire (FM6DD) or plug socket (FM4DDE), wait 5 minutes 

for the engine or motor to cool down, then inspect for damage. Vibration is 

generally a warning of trouble. Check damaged parts and clean, repair and/or 

replace as necessary.

•  If the machine topples over during operation, immediately turn off the engine or 

motor and for the FM4DDE model, disconnect the power cable.

•  When using the FM4DDE, always use with a circuit that has an RCD to prevent the 

chance of an electric shock.

Safety with Maintenance

•  Inspection and maintenance must be done with the motor and driving unit 

switched off and the spark plug (FM6DD) or power cable (FM4DDE) disconnected. 

Wait 5 minutes for the engine or motor to cool down.

•  Any worn or damaged parts must be replaced, to ensure that the chipper 

is maintained and in a safe state. Only use Forest Master spare parts for 

replacements. Contact us to arrange.

•  Never use the wood chipper with damaged or worn cables.

•  Never, under any conditions, remove, bend, cut, fit, weld or otherwise alter 

standard parts on the wood chipper. This includes all shields and guards. 

Modifications to your machine could cause personal injuries and property 

damage and will invalidate your warranty. 

•  Never use a pressure washer or running water to clean the chipper. This might 

lead to water ingress in the engine or the bearings (invalid warranty). Do not use 

any aggressive cleaning products.

•  Never transport the chipper with the motor still running.

•  Prior to transport, use appropriate fixing materials to fasten the chipper to the 

fixing points on the load surface.

•  Prior to storing the machine, make sure that it has been restored to a sufficient 

state (i.e. clean and free from debris). Apply oil to the knives, the knife drum 

and the bearings to protect them from corrosion. This is especially the case for 

storage during long periods of inactivity of the appliance. 

•  Store the machine in a dry, closed room, out of children’s reach.
