Bucket teeth replacement
Replace the bucket teeth before the bucket teeth base is worn.
Warning: When replacing the bucket teeth, it is very dangerous if the working device
moves accidentally due to wrong operation. Therefore, before replacing the bucket teeth,
put the working device in the locked state, then shut down the engine and lock all joysticks
firmly. During replacement, wear necessary protective equipment to prevent the lock pin
from flying out.
Replace the bucket teeth
1) Place the bottom of the bucket on blocks for removal.
Check that the working device is in a stable state and the
bucket is placed horizontally. Shut down the engine.
2) Loosen the screw and nut on the bucket teeth by using
the hexagon socket screwdriver and wrench to remove
the bucket teeth.
3) Clean the mounting surface. Install the new bucket
teeth into the teeth base, and then tighten the screw and
nut by using the hexagon socket screwdriver and wrench
to install the bucket teeth on the tooth base.
