Problems and solutions in the use of KNDMAX wood chipper

Problems and solutions in the use of KNDMAX wood chipper
Possible phenomena in use	Cause analysis	Consequences (harm)
Poor feeding effect	The flying knife is worn and not sharp	Resulting in damage to the knife or rotor
	The bottom knife is worn and the edges become arcs,	Resulting in damage to the knife or rotor
	Improper installation of the flying knife	Results in excessive wear of the bottom knife and flying knife
	Too many hard side branches on the branches	The branches cannot be pulled in
	Too many branches are added at the same time	Resulting in damage to the knife or rotor
	The belt tension is not appropriate, too loose or too tight	Resulting in damage to the belt, rotor or engine shaft
	The machine runs too slowly	The large branches cannot be crushed, or the engine stalls and causes jams
	Note: The maximum operating speed of the machine is set at the factory, which is the most economical speed and cannot be adjusted arbitrarily
Poor discharging effect	There are a lot of fresh leaves on the branches (depending on the type of tree)	A large number of newly leached leaves will cause the discharge port to be blocked, resulting in excessive wear of the blade
	Crushing too wet materials
	The blunt blade is not conducive to discharging	Resulting in damage to the knife or rotor
	The deflector is too low and the discharge opening is small	The crushed material flows back to the discharge hopper, accelerating the wear of the cutter
	The machine speed is too low
	Note: The maximum operating speed of the machine is set at the factory, which is the most economical speed and cannot be adjusted arbitrarily
The blade is excessively worn	Adding a large number of small branches at the same time, results in a large amount of cutting
	Crushing untreated tree roots with gravel and sand
	Adding branches with large diameters
	The bottom knife is blunt and not replaced
	The gap between the fly knife and the bottom knife is incorrect
	The machine speed is too low and the power is insufficient
	Note: The maximum speed of the machine is set at the factory, which is the most economical speed and cannot be adjusted at will
The blade is damaged	The worn blade has been working for too long and has not been replaced or sharpened in time
	Stones, metals or other foreign objects have entered the machine
	The gap between the fly knife and the bottom knife is too small
	The blade and the cutter table were not cleaned before installing the fly knife
	The fly knife fastening bolts were not tightened
	The bottom knife was not installed and tightened
The rotor was damaged (cracked)	The worn blade has been working for too long and has not been replaced or sharpened in time
	The worn bottom knife has been working for too long and has not been replaced or sharpened in time
	The blade is sharpened at an incorrect angle or the grinding temperature is too high, causing the blade to partially lose hardness
	The gap between the fly cutter and the bottom cutter is incorrect
	The bolts are not tightened with a torque wrench
	The width of the fly cutter becomes smaller after multiple sharpenings, causing the bolt head to touch the bottom cutter
	Too much material is filled into the cutter box
	The bearing seat is not tightened correctly after maintenance
The V-belt is damaged	The pulleys are not in a straight line
	The belt tension is not appropriate, it is too loose or too tight
	The engine/motor is not fixed properly
	Too much material is filled at one time
	Extreme temperature changes
The pulley and engine crankshaft are damaged	The pulley is not fixed properly
	The pulley is not checked for tightening or displacement before starting the machine
	The correct key is not used
	Too much material is filled at one time and long-term overload operation
	The locking washer is not used or used incorrectly
