6�2 MAINTENANCE
6�2�1 BELT TENSION / ROTOR BRAKE:
The machine is designed with a clutch on the engine shaft equipped with an internal brake that when
engaged is used to brake the engine pulley and prevent it from turning.
This in turn will stop the belt dive and rotor plate pulley. When the belt is in disrepair or loose, the ability
to stop the rotor quickly may be affected.
Therefore it is important to periodically check the condition as well as the tension of the belt.
Frayed, cracked or worn drive belts should be replaced. Drive belt should deflect no more than 1/4 to
3/8" (6 mm to 10 mm).
Drive Belt Tension Check and Adjustment:
1.
Ensure the engine is off (ignition switch is off and the fuel valve is closed).
2.
Remove the 4 bolts that hold the belt shield to the chipper, remove the belt shield.
3.
Check the tension by pushing on the belt with your fore finger and measure its defection. Drive belt
should deflect no more than 1/4 to 3/8" (6 mm to 10 mm).
4.
If the belt requires adjustment, loosen (do not remove) the 4 x bolts that hold the engine mount to the
main frame, (2 on each side of the motor mount).
5.
Turn the belt tensioning bolt clockwise, to pull the engine mount outwards to tighten the belt or turn the
bolt clockwise, to loosen the belt.
6.
Snug 1 bolt on each side of the engine mount.
7.
Check the tension by pushing on the belt with your fore finger and measure its defection. Drive belt
should deflect no more than 1/4 to 3/8" (6 mm to 10 mm).
8.
If the tension is incorrect, loosen the engine mount bolts and adjust the belt tension bolt as required.
9.
When tension is correct, tighten up all four engine mount bolts and replace the belt shield and bolts.
