5.0 CONTROLS
5.1 Start/Stop
Before starting machine ensure cutter blades are locked in
place and all guards are closed or in position.
When an isolator which is situated at rear of machine is
fitted, proceeds as follows:-
To start, turn isolator to 'l', then press green button
'B', FIG.13, on left hand panel to start cuter. To stop,
press the red button 'C'. To isolate machine, turn
isolator to '0' position. Where no isolator is fitted,
control is simply via the panel start/stop button.
5.2 Brake Motor
Brake motor (extra) comes into effect when stop button is
pressed, cutterblock cannot then be rotated. To release
brake, turn switch situated on front right of machine,
clockwise.
5.3 Variable Feed Speed Control
Feed roller drive is by infinitely variable pulley and belt
from the motor. To alter feed speed, proceed as follows:-
Turn variable feed speed handwheel 'D' clockwise to
decrease speed, anti-clockwise to increase speed, FIG.13.
a) When altering feed speed, motor must be turning.
b) To prevent undue wear on variable pulley, turn
handwheel throughout complete range once weekly.
5.4 Power Rise and Fall
Power table rise or fall drive is transmitted from a
gearbox by a timing belt to table rise and fall screws,
which is in turn connected by chain to the 3 remaining rise
and fall screws and manual rise and fall handwheel.
To power raise or lower table, proceed as follows:-
a) Ensure top cover and side covers are secured in
position.
b) Move power rise and fall switch 'E' FIG.13, in
direction required to either raise or lower table. For
micro table adjustment when required, turn handwheel
c)
IF I •
NOTE:
If so desired, handwheel 'F' may be used to
rise and fall the table through its full
travel.

5.5 Digital Timber Thickness Indicator
A digital timber thickness indicator 'G' is conveniently
situated on the control plate FIG.14. The scale is
operated by vertical movement of the table.
This indicator is preset before despatch from our works,
but should the setting be disturbed for any reason, then
proceed as follows to reset indicator:-
a) Isolate machine electrically.
b) Remove left side base cover.
c) Ensure table rise and fall belt is correctly tensioned,
(refer to 7.6(g)).
d) Replace all covers.
e) Start machine and thickness a sample piece of timber,
then accurately measure timber thickness.
f) Loosen MS grubscrew on timber thickness indicator 'G'
and turn handwheel 'F' FIG.13, until indicator display
corresponds to the measured timber thickness.
5.6 Table Rollers
The anti-friction rollers or bed rollers, revolve on sealed
for life bearings which require no lubrications. The
height of these rollers may be adjusted by means of hand
lever 'H' on the front of the table FIG.14.
A clockwise rotation would raise the rollers to a maximum
of 1.Sm above the table surface.
An anti-clockwise rotation would lower to a minimum of
O.OSm above table surface.
The maximum height position is for use with wet, twisted or
roughly sawn materials, where feeding is a most important
feature. In all cases the lowest position consistent with
good and regular feed should be used to give the best
possible results.
Should the rollers be removed for any reason, care must be
taken to replace them exactly as before, otherwise the
settings will be disturbed.
It must be emphasised that a really good surf ace finish
from a thicknessing machine is only possible when the face
of the timber resting on the machine table is flat and has
a reasonable finish. Whenever practicable, this face
should be pre-machined on a surf acer to remove twist and
other irregularities. -

5.7 Rear Pressure Bar Settings
Rear pressure bar is adjustable by means of hand lever 'J'
FIG.15 on the front right hand side of machine. Some slight
advantage in finish or feeding may on occasions be obtained
by raising or lowering pressure bar.
5.8 Motorised Knife Grinder (Optional)
To operate open top hood. By doing so the cutterblock motor
is isolated and the power is transferred to the grinder motor.
Before commencing grinding operation located the indexing
plunger by lever 'K' FIG.16 into one of the peg holes in the
indexing device. Slide grinder to bring grinding wheel into
position over knife blade and ensure grinding wheel is clear
of knife blade before starting. Screw grinder pull handle
(which when not in use if secured to left side top cover) into
slide bracket 'M'. Start grinder (switch at rear of machine)
and screw down onto blade by knurled adjuster 'L' until a
light cut is made. Using pull handle, push slide across,
traversing rapidly fully over length of blade and back to
starting point, repeat until cut is finished and return
grinder to starting point. Pull device and relocate, repeat
grinding operation and above sequence on all four knives.
NOTE:
Each cut adjustment should be made on all blades.
Do not treat each blade individually as this will
result in variable amounts of removal causing balance
problems. Before starting each grinding stroke
return grinder to position shown.
After treating all blades, stop grinder motor, unscrew pull
handle and pull lever 'K' back into free position.
NOTE:
If hand lever 'K' is not in free position top hood
will not close. Replace top hood before operating
machine.
Modification to Knife Grinding Attachment
We have modified the knife grinding. attachment to grind the
knives at an angle of 45 degree, this will give a longer edge
life, with no deterioration in surface finish. As our
supplier will continue to supply knives at 35 degrees, the 45
degree angle will be the primary angle and the 35 degree will
show as a secondary angle.
IMPORTANT
DRESSING OF CIRCULAR GRINDING STONE
Keep the grinding face on the circular grinding stone to
within 1/8" (3mm) wide as shown in FIG.26. This will ensure
accurate and clean grinding knives.

7.0 MAINTENANCE
All adjustments and alignments following have been
carefully set and checked and the complete machine
thoroughly tested before despatch from the works.
During the first few weeks of operation and at regular
intervals afterwards, certain items such as belt tension
and chain tension should be checked carefully. When
adjustments are necessary, proceed in accordance with the
relative instructions given.
7.1 Feed Roller Settings
These are preset at works. Should the replacement of feed
rollers be fitted at any time, the settings should be
carefully checked with FIG.17. Some slight advantage in
finish or feeding may on occasions be obtained by
increasing or decreasing the tension on the feed roller
springs.
7.2 Front Pressure Bar Settings
These are preset at works. Should the replacement of front
pressure bars be fitted at any time; the settings should be
carefully checked with FIG.17. Some slight advantage in
