Tips: Keep the machine running for another 1-2 minute after feeding the last branch,
then turn the throttle lever to the lowest position before stopping the engine.

5. Basic Maintenance

Allow the machine to cool down before making any inspections or any
maintenance. (If the machine is equipped with an electrical start system, remove the
key from the contact and disconnect the battery)

5.1 Lubricating Oil

The main shaft bearing needs lubricating oil. After a period of usage, it is necessary
to grease the bearing. How often to lubricate is determined by the environment and
the frequency of usage. The bearing needs to be greased after 50 hours of operation as
insufficient lubricating oil can damage the bearing.

5.2 Chipper Parts Regularly Checking

Check all the parts regularly (1-2 times a month) including bearing, blades, belt and
etc. Make sure the blades are flexible and sharp. Replace the blades as soon as the
chipping performance begins to deteriorate. Blunt blades will impact working
efficiency and cause damage to the machine.

5.3 Changing the blades:

 Stop the engine (Put the on/off switch in the "off" position) and disconnect the
safety switch cable.
 Remove the feeding chute. (Two people required)
