There are two bearings, one outside and the other inside of the 
housing. The bearings are greased when they are new, however it is a 
good idea to grease them after a couple of hours use. One or two 
pumps are sufficient. Be careful not to over grease. Over lubrication 
can damage the bearings. 
If the machine’s cutting disk strikes a foreign object, or if the machine 
begins to make an unusual noise or vibrates excessively, immediately 
shut off the engine. Allow the cutting disk to come to a complete stop. 
Remove the spark plug from the engine to avoid any accidental start. 
Then perform the following steps: 

Inspect for damage.

Repair or replace damaged parts.

Check for any loose parts and tighten to ensure continued safe
operation.

7.4.

 

Knife and wear plate inspection. 

Be careful and wear gloves when working near the knives because 
their edges can cut you if you come in contact with them. 

7.4.1.

 

Routine inspection of the knives for sharpness and wear plate for a sharp 

edge will ensure that wood chipper is operating at full efficiency. Using dull 
knives or a rounded wear plate will decrease performance and cause excessive 
vibration that will damage the machine and make chipping difficult for the 
operator.  

7.5.

 

Knife removal and replacement. 

7.5.1.

 

This wood chipper is equipped with two pieces of chipper knives mounted on 

the cutting disk. When the knives get dull or show visible nicks, the machine 
will lose its self-feeding action and 

the wood will have to be pushed in. The 

wood will tend to come out in long strips.

 

7.5.2.

 

If the knives need to be removed for sharpening

,

 

loosen the clamp by  

 

unscrewing the locknut to open the discharge chute and remove the feed  

 

hopper. With a 13 mm ring spanner loosen the locknut's at the back of the 

 

cutting disk. If the bolt head turns, hold it with a 5 mm hexagonal Allan key. 

 

DO NOT  try to loosen the bolt with the hexagonal Allen key. 

7.5.3.

 

Remove the dull or damaged knives and visually inspect the cutting disk slot 

and knives mounting area and be sure they are clean and that the replacement 
knives will be able to mount flush against the cutting disk. Remount new or 
sharpened knives with the knife edges facing up in the reverse procedure, 
making sure that all mounting surfaces are cleaned beforehand. 

If the cutting disk surface is not cleaned properly and the knives are 
not mounted flush on the cutting disk, the knives could crack when 
the hardware is tightened. 

7.5.4.

 

The clearance between the knives and wear plate should be approximately 

1mm on the inside closest to the bearing and 3mm on the outside edge of the
