if you want to use the high output for loading, you can close the low output in return.
In the process of installation, do not place hands or any other body parts within
a radius of cutter wheel rotary. Do not touch the blades with your hands or any
other body parts. Considering the heavy weight of the machine, please do not try to
install it by oneself in case of the possible injury. All bolts, nuts and washers have
been fixed on the machine in the factory, please remove them before assembly
and put back on the machine at the same locations.
4. Operating Instructions
4.1 Starting Machine:
❖Before starting the engine, make sure the correct engine oil is added first (see
chapter 5.4). Ensure the machine is on stable level ground.
BWM PRO 100 Series Manual Book V1.01
B.W. Machinery

❖Turn switch to ‘ON’ position.
❖Turn the choke lever to position and open the fuel valve.
❖Make sure emergency switch is off.
❖Pull the starting cord until the engine starts. Push the choke lever off.
❖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.
4.2 Chipping:
Always wear gloves and safety goggles when using the shredder.
Make sure use highest speed while chipping, when chipping branches with a big
diameter, always feed the bigger ends into the chute first.
Advice: 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.
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)

4.3 Emergency Switch:
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
4.4 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.

4.5 Stopping Machine:
Make sure the machine is completely emptied before stopping the engine (otherwise
rotor may be jammed when using it for next time).
Tips: Keep the machine running for another 1-2 minute after feeding the last branch,
then turn the throttle lever slowly to the lowest position before stopping the engine.
5. Basic Maintenance
Allow the machine to cool down before making any inspections or any
maintenance. (If the machine is equipped with an electrical start system, remove the
key from the contact and disconnect the battery)
5.1 Lubricating Oil
The main shaft bearing needs lubricating oil. After a period of usage, it is necessary
to grease the bearing. How often to lubricate is determined by the environment and
the frequency of usage. The bearing needs to be greased after 50 hours of operation as
insufficient lubricating oil can damage the bearing.
BWM PRO 100 Series Manual Book V1.01

5.2 Chipper Parts Regularly Checking
Check all the parts regularly (1-2 times a month) including bearing, blades, belt and
etc. Make sure the blades are sharp. Replace the blades as soon as the chipping
performance begins to deteriorate. Blunt blades will impact working efficiency and
cause damage to the machine.
5.3 Changing the blades:
❖Stop the engine (Put the on/off switch in the “off” position) and disconnect the
safety switch cable.
❖Remove the feeding chute. (Two people required)
❖Put a block of wood into the hole (see Fig.1). Pull the starter cord some more
until the rotor is blocked. Now it is safe to unscrew blade bolts. Always use
gloves when handling the blades.
❖Remove the blade anvil (see Fig.2).
❖Give a really good clean of chipper blades and anvil and make sure there is no
dirt.
❖Put anvil back to the chipper and screw on (make sure to keep anvil bolts loose as
you need to adjust it later).
❖Use thread locker on 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).
❖After installing the blades, check the gap between the blades and the anvil. The
gap should be no smaller than 0.5mm and not bigger than 1mm. (See Fig.3)

5.4 Changing engine oil:
Unscrew the bolt to drain the engine oil. Screw the bolt on and add new engine oil.
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.
6. Transport and Storage
1. To move the machine around, grab onto the handle firmly and push or drag the
machine. Pay extra attention when moving around rough terrain or sloping areas.
2. To transport the unit, the discharge chute can be removed and the unit will fit into a
van or utility vehicle, tied in an upright position. Ensure the unit is never tipped to its
side when engine oil is filled as it can flood the engine.
3. For storage, keep the machine out of reach of children. Store the machine in a well
ventilated place. Drain the fuel into a petrol tank if not using is for an extended period
of time.

7. Troubleshooting
Problem
Solution
1
Engine cannot be started
Read the engine users’ manual, check the fuel
ON-OFF, see if it’s ON, check if gets enough
fuel and engine oil, check the emergency stop
button.
2
Engine stops midway
Check if the engine is stopped by overloading,
see if there is any blockage in the chipping
chute. Check the emergency stop button.
3
Rotor blocked
Stop the machine, and remove the chute and the
cap of bearing, turn the shaft of roller with a
spanner to clear the blocked material (see
chapter 4.4)
4
Strange noise
Stop the machine, check if the fastener got
loose, if not, let the professionals to check.
5
Blunt blades
Bring the machine to a servicing centre for
sharpening/replacement of blades. Or see
chapter 5.3
6
Damaged belt
Open the belt cover and change the belt.
7
Chipped material too coarse
Need to adjust blade anvil. The gap should be
no smaller than 0.5mm and not bigger than
0.95mm. (see chapter 5.3)
