driven application. These features help protect the engine from damages such as
broken crankshafts and starters.
The clutch obtains its power from engine RPM's. The lower the engagement speed,
and the higher the maintained engine speed, the more torque the clutch can transfer
to the driven unit. Do not operate at less than full RPM's.
• At engine start-up, the engine of your chipper operates under no load until
approximately 1000-1200 RPM'S at which speed the centrifugal clutch engages and
begins driving the rotor.
• Proper rotor speed is 2400 RPM + / - 200 RPM when engine is at full RPM.
• Do not tamper with the engine's governor setting. The governor controls the
maximum safe operation speed and protects the engine. Over-speeding the engine is
dangerous and will cause damage to the engine and to the other moving parts of the
machine. See your authorized dealer for engine governor adjustments.
• Become familiar with successful operating conditions and avoid those that can
overload and damage the machine.
• Do not overload or attempt to chip material beyond manufacturers
recommendation. Personal injury or damage to the machine could result.
• Learn to recognize the sound of the machine when it is overloaded.
• If the machine becomes jammed by overloading or any other cause, stop the
machine immediately.
• If you jam the machine and do not stop the engine, it can:
• Burn the belt.
• Ruin the clutch.
• Only your operator experience will tell you how fast you can successfully feed limbs
into the machine.
• Clutch damage can be costly and damage is not covered under warranty. For this
reason, it is important that you immediately shut off the machine if it becomes
jammed.
Clutch maintenance
The centrifugal clutch on this machine is permanently lubricated and does not require
oil or grease. If, after long periods of use, the drum wobbles excessively, replace the
drum assembly.
Always replace shoes and springs in sets. Whenever shoes are changed, replace all
springs.
Clutch removal
1. Remove clutch from shaft by removing bolt and washers.
2. Side clutch off shaft
