Maintaining The Wood Chipper
Regular maintenance is essential to ensure the best performance and long life
of your machine. Please refer to this manual and the engine manufacturer’s
user manual for maintenance procedures.
Before performing any maintenance procedure or inspection, stop
the engine, wait five minutes to allow all parts to cool. Disconnect
the spark plug wire, keeping it away from the spark plug.
Disconnect the Battery Terminals (Electric start only).

There are many questions when it comes to greasing bearings. All WoodMaxx
implements are now equipped with bearings that are factory greased so that
33% of the race is full of grease, this allows for operation at all speed ranges.
In a clean, dry environment adding more grease to the bearing is not required
for at least 500 hours of use. This is counter intuitive to many people that
have older equipment and are used to pumping grease into the bearings daily.
Modern high quality bearings are made from better steel alloys, provide higher
tolerances, increased rubber seal compounds, and better quality lubricants.
These recommendations are based on load, spindle speed, operating
temperature, and environmental conditions. More grease is not better, rather
is counterproductive and can cause the bearing to generate heat and lead to
premature failure. You should never pump grease into a bearing until the seals
push outward, this is a sign that too much grease is applied, and can deform
the seal causing an entryway for contaminants. Follow the bearing lubrication
schedule below for optimum performance and long bearing life.
2-pump shots of grease after 500 hours
1-pump shot of grease after 500 hours
2-pump shot of grease after 250 hours
1-pump shot of grease after 250 hours
1-pump shot of grease after 50 hours

Wood chips alone do not constitute dust and can be considered a clean
environment. Unless you are using the chipper in a wet and dirty environment,
grease the bearings at 500 hour intervals.
