If you’re starting the 15HP Wood Chipper with the electric start while the engine is cold, be sure to set the choke level to full choke. When you start the engine you should then let it run at low throttle for around 30 seconds before you begin to slowly increase the throttle level.

If you’re starting the 15HP Wood Chipper with the electric start while the engine is warm, set the choke level to around half (middle choke position). When the engine has started, you should still let the chipper run at low throttle for around 30 seconds before you start to slowly increase it.

The belts turning or moving out of place means that the pulleys are out of alignment.

Check the lower to upper pulley using a spirit level if possible. You can easily move over the engine by loosening the 4 bolts.

In the event that your wood chipper engine is producing smoke, please follow this checklist:

Check the oil level and adjust as needed.

Check the air filter and clean or replace if needed.

You may be using the wrong oil – too light for the temperature. We recommend reading the Engine Owner’s manual for more detailed information regarding this subject.

Clean the cooling fans if they’re dirty.

In the event that your wood chipper won’t start, please follow this checklist:

Check that the Throttle Lever is in the ‘RUN’ position

Is the air filter clean? If it’s dirty, change it by following the instructions provided in the engine manufacturer’s owner’s manual.

Is the spark plug clean? If it’s fouled or cracked, change it. If it’s oily, leave it out, hold a rag over the plug hole and pull the recoil cord several times to blow out any oil in the cylinder, then wipe off the plug and reinsert it.

Are you using fresh and clean unleaded gas? If it’s old change it. Use a fuel stabilizer if you keep gas longer than 30 days.

Does your engine have the right amount of clean oil? If it’s dirty, change it following the instructions provided in the engine manufacturer’s owner’s manual.

Check the oil level and adjust as needed.

In the event that your wood chipper won’t start, please follow this checklist:

Is the ignition switch in the ‘ON’ position?

Is the fuel shut-off valve on?

Are you using fresh, clean fuel? If the fuel is old, change it. Use a fuel stabilizer if you keep fuel longer than 30 days.

Is the spark plug clean? If the spark plug is dirty or cracked, change it. If it’s oily, leave it out, hold a rag over the plug hole and pull the recoil cord several times to blow out any oil in the cylinder, then wipe off the plug and reinsert it.

Is there sufficient oil? Check the engine oil level and if necessary top up to the current level.

Is there dirt in the carburetor? Undo the bolt holding the float chamber to the carburetor, empty out any fuel and clean the inside using fresh clean petrol. Remove the jet in the bottom of the carburetor and clean it. Refit the jet and the float chamber.

The tension of the belts should be checked before each use. Additionally, when the machine is new or after the belts have been replaced, the tension should be checked after the first 15 minutes of use as the belts will stretch.

To adjust the tension loosen the four mounting bolts that secure the engine plate to the chipper. The plate can then be moved backwards or forwards using the two adjusting bolts. To adjust the bolts, loosen the lock nuts then move the adjusting bolts backwards or forwards the required amount.

Once the adjustment is correct, you can then tighten the lock nuts. You should be careful to adjust each bolt by the same amount.

Finally, re-tighten the four mounting bolts.

You should perform regular maintenance checks on your wood chipper. This is the best way to ensure optimal performance and long life of your machine.

First Time Use

Ensure that you check the tension of the belts before first time use. You should then run the chipper for no longer than 10 to 15 minutes before checking the tension of the belts again on your first use. After this you only need to check the tension of the belts before each chipping session.
