ENGINE OIL
For transportation reasons, your machine’s engine comes from the factory without any oil in it. Before starting the engine for the first time you must put oil the engine.

This engine uses quality 4-stroke Briggs and Stratton SAE30 or Honda 10W30 oil, depending on the model.

Filling the oil sump:

• Place the machine on a flat, horizontal and uncluttered surface.
• Unscrew the oil filler cap (Figure 7).
• Add 1.1L of oil.
• Wait 1 minute for the oil to completely go down to the crankcase.
• Clean the dipstick from the oil with a cloth.
• Insert the rod and screw on the oil cap.
• Unscrew the plug again and check the mark left by oil on the dipstick. The mark left by the oil must be between the minimum and maximum marks (Figure 8).
• If the mark is below the minimum, add a little bit more oil and recheck.
• If the mark is above the maximum, you will have to remove oil from the crankcase. To do this, tilt the machine and let out a small amount of oil (put a container at the end of the tube to prevent oil spilling on the machine or the ground).

STARTING THE MACHINE

CHECKPOINTS BEFORE STARTING
The machine must be operated as instructed below:
Keep hands, other extremities and clothes clear of the feeding chute, clear of the discharge chute and clear of all rotating elements.
Maintain a good balance on both feet. Do not lean on the machine.
Maintain yourself well clear of the discharge area whilst the machine is working. The use of working gloves, ear protections and protective glasses is mandatory. The machine is designed for outdoor use only. Avoid using the machine in outdoor areas with a high probability of exhaust fumes.
Never insert your hands into the feeding chute until the machine has been stopped and the blades have stopped rotating.
The pieces of wood that might have got stuck transversally must only be removed when the machine has been stopped completely and the blades have stopped rotating.
Transportation of the machine should be carried out by two persons to avoid possible injuries.

STARTING THE ENGINE
Before starting the engine make sure to check the engine oil and fuel tank. To start the machine:

1. Turn the switch to ‘ON’ position.
2. Turn the choke lever to position and open the fuel valve.
3. Pull the starting cord until the engine starts. Push the choke lever off.
4. Turn the throttle lever to fastest position. (must use highest speed while chipping)
   If engine is hot, it is not necessary to use the choke when restarting. Figure
5. 

NOTE
This machine is only used for the purpose that has been designed. To use it for other purpose may cause injure to people or damage to machine.
Put the branches into the chute and when they are pulled in, let them go. The branches will be pulled in automatically.

Tips
The hardness of the wood varies, of different wood type, the time between pruning and chipping and how dry the branches are. This machine performs best if the branches are chipped fresh right after pruned.
CAUTION
Dry wood will wear blade faster than normal, even damaging the blades.

STOPPING THE ENGINE

1. Change the engine to idle status by turning the throttle to ‘TURTLE’ position for a minute.
2. To stop the engine, turn the engine ‘ON/OFF’ switch to the ‘OFF’ position.
3. When the engine has stopped completely, turn the fuel lever to the ‘OFF’ position as well.

Tips
Keep the machine running for another 3-5 seconds after feeding the last branch, and then turn the throttle lever to the lowest position before stopping the engine.
If the machine gets jammed, stop the machine, disassemble the bearing cover, and turn the rotor a few degrees by spanner till the rotor can turn freely. Check machine after work, to ensure all bolts, nuts and screws are tight. If loose, tighten them.

USING THE MACHINE

CHIPPING BRANCHES

1. Stand to the side of the hopper, ensuring you have a stable stand and firm footing.
2. When placing long branches into the feeding chute, remove twigs and smaller branches so that you are feeding a thin, straight piece into the machine.
3. Place branches ‘thick-end-first’. Allow the machine’s blades to take the branch from you. You will feel the blades pull the branch from you.
4. When finished chipping, turn ‘OFF’ the machine, allow all moving parts to come to a complete stop. Disconnect the spark plug wire before moving the machine, emptying the bag, unclogging the inlets or outlets, filling the fuel tank, or performing maintenance and repairs.

Always wear gloves and safety goggles when using the shredder.

Chipping Tips:

• DO NOT feed materials in excess of the diameter indicated. Large branches will cause the motor to stall.
• Chipping wood when it is green is easier on the machine. The blades will stay sharper for longer. The hardness of the wood depends on the wood type, the time between pruning and chipping and how dry the branches are. The machine performs best if the branches are chipped right after pruning.
• Make sure use highest speed while chipping, when chipping branches with a big diameter, always feed the bigger ends into the chute first.
• The chipper/shredder will work best if the blades are sharp. Rotate, sharpen, or replace the blades as soon as chipper/shredder performance begins to deteriorate.

If the engine is slowing down while chipping, reduce the feeding rate of the branches. Blunt blades may also be the problem. (see chapter 5.3 on how to change the blades) If the machine becomes jammed, stop the engine immediately. Remove the blocked materials and restart the engine. (see chapter 4.4)

EMERGENCY SWTICH
The emergency stop button is located on left side of chassis. Push the emergency stop button by pressing the button and the engine will stop immediately. To release the emergency stop button, turn the red button. Within half a turn, the button is released (pump up) and you can restart the machine. Figure 10.

ROTOR JAMMED
The rotor may be blocked due to blunt blades, incorrect usage of emergency button while chipping, machine not completely emptied before stopping the engine, or engine has stopped due to overloading of the chipper with too much branches and etc.
Please follow the steps below to unblock the rotor.

• Switch off the engine, and remove the feeding chute.
• Remove the bearing cover holder from the bearing housing by loosening one bolt.
• Turn the rotor shaft in counter clockwise direction by rotor spanner.
• Use a branch or a stick to remove any blocked materials in the drum. Do not use your hands. Figure 11.

MAINTENANCE AND SERVICE

WARNING: Turn OFF the machine, allow all moving parts to come to a complete stop, and disconnect the spark plug wire before moving the machine, emptying the bag, unclogging the inlets or outlets, filling the gas tank, or performing any maintenance and repairs.

VISUAL INSPECTION
Before and after every use of the wood chipper, it is recommended that the following inspection process takes place. This is quick and easy, and ensures your safety as well as the machine’s performance.

1. Check the chutes and guards for cracks, holes and loose bolts.
2. Check the frame and base of the machine for cracks or damages.
3. Check all the bolts and screws to ensure tightness.
4. Wear gloves, and check the blades are not cracked or loose.
5. Check the engine oil level using a dipstick.

CLEANING
It is strongly recommended to clean the machine after every use. After finishing the job, turn off the machine, allow the engine to cool fully, and remove the spark plug.
Brush off or vacuum excess wood chippings and wipe off the remaining dust from the exterior of the machine with a dry cloth. Do not expose the machine to water or attempt to clean by pouring water on/into it. Remove any chips or debris from the hopper and the discharge chute.
It is increasingly difficult to clean this machine the longer you let it sit unclean.

The machine’s performance will naturally decrease if it is not properly cared after.
To clean the engine from built-up resins, you may need to purchase an engine cleaner.

MAINTENANCE OF ENGINE

SPARK PLUG
After every 50 hours of running the spark plug should be checked. Check the colour of the deposits on the end of the spark plug. It should be a brown colour. Remove all deposits using a stiff brass wire. Check the spark plug gap (Figure 12) and adjust if required. The correct gap should be between 0.7 to 0.8mm.

ENGINE OIL REPLACEMENT
The oil should be replaced after approximately 50 hours of use. It is recommended you maintain an estimate of this by tracking your usage of the machine.

1. As per normal start-up, ensure the machine is on a flat, dry surface and follow the previous instructions to startup the machine. Allow the engine to warm for several minutes before turning off the engine.
2. Remove the oil filler cap as seen in Figure 13.
3. Place an oil pan under the engine to catch the oil. Remove the oil drain plug (as displayed in Figure 14) to drain the oil fully. A tube or similar device is recommended to avoid spilling the oil.
4. Check the oil drain plug, gasket, and oil filler cap to ensure each part is not damaged.
5. Add fresh engine oil up to the upper level of the dipstick, as seen in Figure 14.

Tips:
For Honda GX390 model, add 1.1 litre (1100mL) of genuine Honda 10W30 engine oil.
For Briggs & Stratton 13.5HP model, add 1.1 litre (1100mL) of genuine Briggs & Stratton SAE30 engine oil.

BWM oil change kit is also available from our online stores or dealers

AIR FILTER
After approximately 50 hours of use, or every month (whichever is sooner), the air filter should be removed and cleaned thoroughly. During this cleaning process, the air filter should also be thoroughly inspected for damages and deterioration. We recommend a water-based degreasing agent. Allow to dry fully before replacing the air filter.
NOTE: Never attempt to run the machine without an air filter in place.

FUEL FILTER
After approximately 150 hours of use, or every 6 months (whichever is sooner), the fuel filter should be removed and cleaned thoroughly. The fuel filter is displayed in Figure 15. As with cleaning the air filter, we recommend cleaning the fuel filter with a water-based degreasing agent.

BLADES AND ANVIL

CAUTION
Blades are extremely sharp, take care please!
Torque scale: 60-70Nm for blade and 35-45Nm for anvil.
Blades and anvil need cleaning after every chipping job, to protect it from corrosion.
Sharpen or replace the blades as soon as the chipping performance begins to deteriorate, or if you notice signs of chips or cracks.

1. Turn off the machine, allow all moving parts to come to a complete stop, and disconnect the spark plug wire.
2. Remove the feeding chute.
3. Put a block of wood into the blade drum (see Fig 16). Pull the starter cord some more until the rotor is blocked. Now it is safe to unscrew the blade bolts. Always use gloves when handling the blades.
4. Remove the blade anvil (see Figure 17).
5. Give a really good clean of chipper blades and anvil and make sure there is no dirt. Put the anvil back to the chipper and screw on (make sure to keep anvil bolts loose as you need to adjust it later). Use threadlocker on the blade bolts (make sure you don’t use too much, normally just a small dip) and screw on the blades (make sure all bolts are tightened).
   NOTE: Check the gap between the blades and the anvil. The gap should be no smaller than 0.5mm and not bigger than 1mm. (See Figure 18).

Sharpening:
Blades must only be sharpened by grinding on a bench grinder. Do not sharpen with hand held equipment. Always sharpen in sets to maintain balance of rotor assembly. Both edges of each blade must be grounded on front at 30° angle and on the back 5° angle over 2mm to ensure correct clearances (Figure 19). Anvil:
For the anvil, change side when the side edge on the tapered top gets blunt. Change the anvil when both sides are blunt to ensure performance of the chipper. Remember to readjust the anvil to a clearance of 0.5~1mm.

LUBRICATING GREASE
It is recommended to grease the rotor bearings daily before use. Use a high temperature EP2 lithium complex grease.

WHEEL TYRE
Check the tyres regularly. Inflate the tube if necessary (tyre pressure 1.5 bar min., 1.9 bar max.).

PERIODIC MAINTENANCE
Perform regular inspections of the machine in order to ensure effective operation of the machine and to prevent risk of injury to machine and user. Replacement parts should be purchased from the official service dealers. The use of non-genuine spare parts may cause accident, injury to the user and scrapping of the machine.
