Noise
Noise levels vary depending on type of material being processed. Also duration of
operation is variable. Noise emission tests have been carried out and the guaranteed
sound power level (Lwa) is displayed on a decal as follows:
Evo205DT –114dB(A)
Minimise noise and fuel consumption by activating Economy Mode on controller (Section
4.6), switching from Run to Idle, or stopping the engine whenever chipping is not in
progress.
CAUTION! Operators must wear appropriate ear protection. Bystanders must be
kept away from proximity of machine.

3.4 Safety Controls and Switches
3.4.1 Emergency Stop Bar and buttons (fig 3.4.1)
In the event of an emergency, push stop bar right in or press stop button to STOP feed
rollers.
Once the emergency has been rectified, pull Red stop
button back up if down.
Press Green button to restart rollers to continue Feed
In, or press and hold Blue button to Feed Out to eject
material. Stop bar returns to work position but does
not restart feed rollers.
If stop be tripped accidentally in normal working
conditions, i.e. NOT an emergency, then Feed In can
be recovered by pressing Green button, having first
checked stop bar is free to move and stop buttons are
up in work position.
To reverse feed rollers (Feed Out) press and hold
Blue button. To regain Feed In press Green button.
3.4.2 Engine Stop (fig 3.4.2).
To stop engine turn key anticlockwise to ‘0’ position.
To restart, turn key clockwise to Start.
To disable machine, remove key.
CAUTION! Do not restart engine until hazard has been removed.
3.5 Control Cut-Outs
Cut-out switch under engine cover prevents starting with covers removed.
Engine overheating is protected by thermal cut-out switch in coolant circuit.
Low engine oil pressure is protected by pressure switch in engine oil pump.
3.6 No Stress System with Smart-Sense controller
Speed sensor disables feed roller FEED IN or FEED OUT mode when engine speed is
below factory pre-set value.
Overload sensor stops and restarts rollers during Feed In.
Economy Mode setting (optional) when unloaded reduces speed to idle after preset time.
Refer to Section 4.6 for further information.

console. Yellow Idle/Run button on infeed chute switches between idle and run speed and
overrides Economy Mode timer setting. Use either of incremental controls to set engine
for transport speed. Blue and Green infeed buttons immobilised when speed is below
chipping speed.
General Note: Maximum and minimum stress speeds, feed roller start speed and Idle
(Eco) speeds are all factory set and locked. Consult dealer or Greenmech Ltd for
resetting.

5.1 Pre-Work Checks:
Check machine is stationary, Key in OFF position or removed, and hand brake applied if separated
from vehicle.
Check that machine is level and infeed chute is not less than 600mm from ground (fig 3.4.3).
Check engine oil level (See Engine instruction manual).
Check hydraulic oil level (See Section 6).
Check fasteners for tightness and hydraulic connections for leaks.
Check condition of blades as follows:
Disengage flywheel clutch (See 5.9)
1) Raise engine cover. Check nothing is rotating.
2) Remove bolts (2) retaining chipper flywheel cover.
3) Using discharge chute handle as a lever, swing back
cover onto stop to expose chipper flywheel and blades. (fig
5.1.1)
CAUTION! Beware sharp edges of blades and
unexpected movement.
4) Turn flywheel to align locking pin with a mating boss (2)
and release pin into boss to prevent flywheel from turning.
5) Remove any loose wood material.
6) Retract locking pin and carefully rotate chipper flywheel
to check tightness of blade bolts and condition of blades (fig
5.1.2).
7) If any bolts are loose, refer to Maintenance Section 6.7 for further action.
8) Retract and turn locking pin to prevent it springing back and replace chipper flywheel cover.
9) Tighten all bolts securely.
10) Remove any loose material and
dust from radiator and engine bay
11) Replace all covers and secure.
Check discharge chute is in desired
position pointing away from infeed
and all clamps are tight. (see
Section 4.4)
Check work area and erect signs and
cone off discharge area if necessary.
Check ALL safety procedures have
been followed.
CAUTION! Always work with chipper level, preferably with the infeed direction slightly down
the slope to minimise the risk of material falling back out.

5.2 Starting Machine (Fig 5.2)
Note: Read Section 4.6 before starting.
CAUTION! Beware sharp edges and dust. Wear protective gloves and eye shield!
Check all other personnel are clear of machine.
Check that feed roller stop bar is free to move, and feed roller Stop buttons in Up (Run) position.
Set Chip / Track switch to Chip.
Start engine (Fig 5.2.1 Fig 5.2.2)
Check that flywheel clutch is engaged.
1) Turn the ON - OFF key to position I. Wait for engine pre-glow countdown indicator to cease
and chipper speed 0 rev/min to be displayed.
2) Turn key to START engine.
3) Press yellow IDLE/RUN button OR press and hold ‘hare’ button (5) on controller until engine
reaches preset operating speed.
4) Press green FEED IN button when ready to start loading chipper.
5.3 Stopping Machine
1) Push stop bar to STOP position, or press down red Stop button to stop feed rollers.
2) Press yellow button to IDLE or press and hold ‘tortoise’ button (1) on controller and allow
chipper flywheel to slow down (fig 5.2).
3) Turn key anticlockwise to OFF (position 0) to stop engine.
4) Wait for chipper flywheel to stop.
CAUTION! Chipper flywheel will take several seconds to stop due to its inertia.

5.4 Blockages
Stop engine and REMOVE key to secure place.
Check that flywheel clutch is disengaged (See 5.9).
CAUTION! Chipped material is inflammable. Expect large volume and prevent from falling
into engine compartment. All material must be removed.
Open chipper flywheel cover. See 5.1 Pre-work checks.
Look into chamber to identify problem if possible, before reaching
in.
Open chipper chamber or on optional version fold down at hinge
to inspect and clear. (see fig 5.4.1
Clean out discharge chute thoroughly with a suitable rod to pass
around bends as necessary.
CAUTION! Beware sharp edges of blades and unexpected
movement of flywheel due to resistance of engine. Wear
protective gloves.
Check if chipper flywheel is free to rotate. Pull top of flywheel in
operating direction of rotation. If so proceed to 6 below.
If flywheel does NOT rotate freely, proceed as follows:
1) Release roller spring tension at adjuster. (fig 5.4.2).
2) Using special bar provided, place in socket, pull as shown (fig
5.4.3) and twist to hook and lock roller away from fixed roller.
3) Inspect rollers and blades from infeed chute and carefully clear
material.
4) Carefully remove excess loose material from around chipper
flywheel and note any obstructions.
5) Carefully rotate chipper flywheel in reverse direction by full
revolution to release blocked material. Use bar against paddle
blades for aid.
6) Carefully remove all material, checking for obstructions.
Check rotation of chipper flywheel.
Check condition of blades. See 5.1.6
Note: Always attempt to find reason for blockage. e.g. blunt blades, slack drive belts.
6) Unhook and release lifting bar and stow.
7) Refit and tension spring adjuster under chassis
8) Re-assemble all covers with correct fasteners and check for security.
9) Start machine as 5.2 and check operation.
Note: If machine will not run, repeat process or contact dealer for
technical advice.
