They are more awkward to handle
The knives dull much quicker
Feed short, stubby pieces of wood into the chipper
They bounce and spin in the inlet chute
Feed short stubby pieces together with longer pieces
Feed branches that are too large
The chipper can easily stall
Put soil, sand, grit, stones, glass, pieces of metal or other foreign objects into the chipper
This will damage the sharp edge of the cutting knives and can rebound and injure the operator
Put root balls and dead wood into the chipper
This dulls the knives quickly
Overload the chipper (max branch diameter 130 mm)
If the cutting rotor is slowing down, feed the material in slower
Allow processed material to build up in the discharge area as this can:
Prevent proper discharge
Result in kickback of material through the feed opening
Transport the chipper while the engine is running
Tamper with the engine governor settings on the chipper
The governor controls the maximum safe operating speed and protects the engine and all moving parts from
damage caused by overspeed
Operate the chipper with blunt knives
This causes excessive vibration which may result in damage to the chipper
Move or tilt the chipper while it is running
Touch any guards or stick hands between guards while the chipper is running
Touch any guards or stick hands between guards
Put hands or any other part of the body or clothing:
Inside the feed chute past the rubber flap
Inside or near the opening of the discharge chute

Leave the chipper on while it is unattended
