Original Instruction Manual | BS12 12” Bandsaw | Version 2.0 | February 2012
1. Health & Safety Guidance
READ ALL THE INSTRUCTIONS IN THIS MANUAL CAREFULLY BEFORE
ASSEMBLY, INSTALLATION AND USE OF THIS PRODUCT. KEEP THESE
INSTRUCTIONS IN A SAFE PLACE FOR FUTURE REFERENCE.
WARNING: When using power tools, basic safety precautions should always
be followed to reduce the risk of fire, electric shock and personal injury.
Safe Operation
1. Eye Protection
The operation of any power tool can result in foreign objects being thrown
into your eyes, which can result in severe eye damage. Always wear safety
glasses or other suitable eye protection. Wear safety glasses at all times.
Everyday glasses only have impact resistant lenses. They are not safety
glasses which give additional lateral protection.
2. Keep Work Area Clear
Cluttered areas and benches invite accidents and injuries.
3. Consider Work Area Environment
• Do not expose the machine to rain or damp conditions.
• Keep the work area well lit.
• Do not use the machine in explosive environments eg. in the presence of
flammable liquids, gases or dust.
4. Guard Against Electric Shock
Avoid body contact with earthed or grounded surfaces such as pipes and
radiators. There is an increased risk of electric shock if your body is earthed
or grounded.
5. Keep Other Persons Away (and Pets)
Do not let persons, especially children, touch the machine, or extension cord
(if used) and keep visitors away from the work area.
6. Store Idle Tools
When not in use, tools should be stored in a dry, locked- up place, out of
reach of children. Do not allow persons unfamiliar with the tool or these
instructions to operate the tool.
7. Do Not Force the Machine
It will do the job better and work more safely if operated within its
intended capacities.
8. Use the Right Tool
• Do not use tools for purposes other than those for which they
were intended.
9. Dress Properly
• Non-slip footwear is recommended.
• Do not wear loose clothing, neckties or jewellery; they can be caught in
moving parts.
• Roll up long sleeves above the elbow.
• Wear protective hair covering to contain long hair.
10. Use Protective Equipment
• Use safety glasses. (See note 1. above)
• Use face or dust shield if cutting operation creates dust.
• Use ear plugs or ear defenders when the machine is in use
11. Connect Dust Extraction Equipment
12. Do Not Abuse the Cord
Never yank the cord to disconnect it from the socket. Keep the cord away
from heat, oil and sharp edges. Do not use the cord for carrying the tool.
13. Do Not Overreach
Keep proper footing and balance at all times.
14. Secure Work
Ensure that your work piece is properly held before starting to cut.
Tel: 01246 561 520 |
www.recordpower.co.uk
15. Maintain Tools With Care.
• Follow instructions for lubrication and changing of accessories
and consumables.
• Inspect electric cords periodically and, if damaged, have them repaired by
an authorized service facility or qualified electrician.
• The mains plug fitted to the machine should always match the outlet. Do
not modify the plug in any way. If a replacement plug is required it should
be fitted by a competent person.
• Inspect extension cords (if used) periodically and replace if damaged.
Always use properly rated extension cord with a minimum core cross
section of 2.5mm2 and a maximum length of 3 metres.
16. Keep Cutting Tools Sharp and Clean
Properly maintained cutting tools are easier to control and less likely
to bind.
17. Disconnect Machine
When not in use, before servicing, changing blades etc. disconnect the
machine from the power supply.
18. Never Leave Machine Running Unattended
Turn power off, do not leave machine until it comes to a complete stop.
19. Remove Adjusting Keys and Wrenches
ENSURE that all adjusting wrenches and keys are removed before switching
the machine ‘ON’.
20. Avoid Unintentional Starting
Ensure the switch is in the “STOP” position before turning on the
power from the main electricity supply. This means the machine will not
automatically start up after a power cut or switching on of the mains supply,
unless you first reset the start switch.
21. Outdoor Extension Leads
Your machine should not be used outdoors.
22. Damp Conditions
If operating a power tool in damp conditions is unavoidable, a residual
current device (RCD) protected supply must be used to reduce the risk of
electric shock.
23. Stay Alert
Use power tools with extreme care and do not use the machine when you
are tired or under the influence of drugs, alcohol or medication.
24. Check for Damaged Parts
• Before use of the machine, it should be carefully checked to determine
that it will operate properly and perform its intended function.
• Check for alignment of moving parts, binding of moving parts, breakage of
parts, mounting and any other conditions that may affect its operation.
• A guard or other part that is damaged should be properly repaired
or replaced by a qualified person unless otherwise indicated in this
instruction manual. Have defective switches replaced by a qualified
person.
• Do not use the machine if the switch does not turn on and off.
25. Warning!
• The use of any accessory or attachment, other than those recommended in
this instruction manual, or recommended by our Company may present a
risk of personal injury.
26. Have Your Machine Repaired by a Qualified Person
• This electric machine complies with the relevant safety rules. Only qualified
persons using original spare parts should carry out repairs. Failure to do
this may result in considerable danger to the user and invalidation
of warranty.
Maintenance and Servicing
This machine requires very little maintenance. This manual gives clear
instructions on installation, set up and operation.
Read these instructions carefully. Remember always to switch off and
unplug from the main electricity supply before carrying out any setting up or
maintenance operations.

2. Additional Health & Safety for 12" Bandsaws
SAFETY IS A COMBINATION OF OPERATOR
COMMON SENSE AND ALERTNESS AT ALL
TIMES WHEN THE BANDSAW IS BEING USED.
WARNING: FOR YOUR OWN SAFETY, DO NOT ATTEMPT TO
OPERATE YOUR BANDSAW UNTIL IT IS COMPLETELY ASSEMBLED
AND INSTALLED ACCORDING TO THE INSTRUCTIONS.
SAFE OPERATION
1. The bandsaw should be bolted to a workbench or suitable stand
where possible.
2. If you are not thoroughly familiar with the operation of
bandsaws, obtain advice from your supervisor, instructor, or
other qualified person or contact your retailer for information
on training courses. Do not use this machine until adequate
training has been undertaken.
3. Never turn the machine ‘ON’ before clearing the table of all
objects (tools, scrap pieces etc.)
4. Ensure that:
(i) the voltage of the machine corresponds to the mains voltage.
(ii) To use an earthed power source (wall socket).
(iii) The cord and plug are in good condition, i.e. not frayed
or damaged.
(iv) No saw teeth are missing and the blade is not cracked or
split. Otherwise replace blade.
(v) The blade is properly tensioned and aligned.
5. Never start the machine with the saw blade pressed against the
workpiece.
6. Never apply sideways pressure on the blade as this may cause
the blade to break.
7. Care must be taken when cutting wood with knots, nails or
cracks in it and / or dirt on it, as these can cause the blade to
get stuck.
8. Never leave the machine running unattended.
9. Ensure the teeth of the blade are pointing downwards.
10. Do not use saw blades which are damaged or deformed.
11. Replace the table insert when it is worn.
12. When cutting cylindrical timber use a suitable jig to prevent
twisting of the workpiece. See section 12 page 28.
13. DO NOT operate the machine when the door or the blade
guard is not closed.
14. Adjust the guard as close as possible to the workpiece
being cut.
15. Ensure the selection of the saw blade and speed are suitable
for the material to be cut. For most wood cutting applications
the fastest of the two speeds should be used.
See section 12.
16. If the mains lead is damaged, it must only be replaced by a
qualified electrician.
17. Never use a long extension cable.
18. WARNING LABELS – It is important that labels bearing Health
& Safety Warnings are not removed or painted over. New
labels are available from Customer Services.
19. MECHANICAL SAFETY – The security of all clamps and work
holding devices should be checked before switching on.
20. WOOD DUST – The fine particles of dust produced in cutting
operations are a potential health risk. Some imported
hardwoods do give off highly irritant dust which causes a
burning sensation. We strongly recommend the use of a dust
collector and dust mask/visor (see section 13). Our Customer
Services Department will also be happy to advise you on the
correct unit for your needs.
21. This machine falls under the scope of the ‘Health & Safety
at Work etc. Act 1974’, and the ‘Provision & Use of Work
Equipment Regulations 1998’. We recommend that you study
and follow these regulations. Further guidance can be found
in the Safe Use of Narrow Bandsaws and the Safe Use of
Woodworking Machinery code of practice booklet (L114)
published by Health & Safety Executive and available by
visiting http://www.hse.gov.uk/pubns/wis31.htm.

Adjustment can be made to the fence (Fig. 7.5, A) in
relation to being square to the blade. This is done by
slackening the four wing nuts on the fence rail (Fig. 7.5, B)
and adjusting the rails position until the fence is square to
the blade.

Note:
This adjustment must be made with the fence in a
clamped position
Fence Alignment 2
Check that the fence (Fig. 7.6, A) is 90º to the table
(Fig. 7.6, B) using a suitable square, there is no need for
adjustment as this area is factory set. However if settings
have slipped during transit slight adjustment may be
needed. The best way to adjust this is by adding extra
washers or shims between the fence rail (Fig. 7.6, D) and
the underside of the table where required.

8. Setting Table Square to Sawblade
Setting the Table Stop at 90º to
the Sawblade
Fig. 8.1
CAUTION! Before carrying out any adjustments or
maintenance ensure that the machine is isolated and
disconnected from the electricity supply.
Tools Required:- Small 90º square (Not supplied)
The table can be set at 90º to the Bandsaw Blade
(Fig. 8.1) by adjusting the table stop screw (Fig. 8.2)
underneath the table.
1. First offer the square up to the blade to give an
indication of adjustment required. (Fig. 8.1)
2. If the table is not at 90º to the blade use table tilting
mechanism (Fig. 8.3) to adjust the table until it is 90º to
the blade. If the table stop screw (Fig. 8.2, A) position is
too high it may be necessary to wind this down out of
the way so 90º can be achieved.
Fig. 8.2
3. Once the table is at 90º to the blade lock off the lock
handle on the table tilt mechanism to secure the table
position (Fig. 8.3).
B
4. Now set the table stop screw (Fig. 8.2, A), the table stop
screw should be adjusted to meet the flat registration
point (Fig. 8.2, B) on the underside of the table (now
set at 90º) to ensure that the table always returns to
square after tilting. The table stop screw is located
above the bandwheel on the lower bandwheel housing.
By first slackening the locking nut and then adjusting
the hex screw the table stop screw can be set correctly.
Re-tighten the locking nut making sure that the setting
is maintained.
Adjusting the Table Tilt Scale
A
Fig. 8.3
Once the table is set at 90º to the Bandsaw Blade it may
be necessary to adjust the angle pointer on the angle
scale so any further angles are accurate. To do this use
a Phillips screwdriver to loosen the pan head screw and
adjust the pointer to 0º (Fig. 8.3, A).
Tilting the Table
The tilt mechanism will be used when squaring the table
to the blade. Tilt the table as follows: Loosen the lock
handle (Fig. 8.3, B) on the table trunnion. Turn the table
tilting knob (Fig. 8.3, C) to adjust the table angle. Use the
angle indicator scale on the trunnion bracket to find the
desired angle. Re-tighten the lock handle to secure
the table.

9. Bandsaw Blade Set Up
Tensioning the Blade
Fig. 9.1
A
CAUTION! Before carrying out any adjustments or
maintenance ensure that the machine is isolated and
disconnected from the electricity supply.
The blade tensioning knob (Fig. 9.1, A) should be used to
increase or decrease tension.
The only accurate way to check a blade is with a tension
meter, these are very expensive so most users may need
another method. We suggest testing the tension by the
amount the blade will deflect sideways. First set the guides
to 6” above the table, ensuring the saw is turned off push
the blade sideways with a reasonable amount of pressure
using the index finger. When pushing with the index finger
a correctly tensioned blade should not move more than a
1/4” sideways (See Fig. 9.2)
However perhaps the most tried & tested way of blade
tensioning is simply: if the bandsaw is cutting accurately
then the blade is tensioned correctly, if the blade tends to
wander & an accurate cut cannot be achieved then the
blade tension needs adjusting.
Fig. 9.2

7
If the machine is to stand idle for a period it is good
practice to slacken tension & re-tension when next using.

9. Bandsaw Blade Set Up - Cont.
Tracking the Bandsaw Blade
Fig. 9.3
Isolate the machine from the supply by unplugging the
mains plug. Set the tracking of the blade before setting the
blade guides.
Once the blade is tensioned, track the blade by turning
the upper bandwheel by hand and adjusting the tracking
knob (Fig. 9.3, A). By turning the tracking knob clockwise
the blade will move towards the back of the bandwheel,
by turning the tracking knob anti-clockwise the blade will
move to the front of the bandwheel. The blade should
run as close to the centre of the bandwheel as possible
(Fig. 9.4). On narrow blades (e.g 1/4" and 3/8") it may
be necessary to run the blade to rear of the bandwheel.
After the blade is tracked in the desired position on the
bandwheel, rotate the wheel several more times by hand
without any further adjustment ensuring that the blade
remains in the same position. Once this has been achieved
lock the tracking knob with the winged nut (Fig. 9.3, B).

Note:
It takes a few revolutions of the bandwheel for the
effecting adjustment on the tracking knob to become
apparent. To avoid over-adjusting, make small gradual
adjustments on the tracking knob and revolve the
bandwheel on a few times to check the alignment of
the blade before making further adjustments.

CAUTION! Before carrying out any adjustments or
maintenance ensure that the machine is isolated and
disconnected from the electricity supply.
First check that all the roller guides are moving freely.
To adjust the upper blade guides, first position the guide
assembly relative to the blade by slackening off the grub
screws (Fig. 9.5, A) and moving the guide carrier
(Fig. 9.5, B) until the roller guides (Fig. 9.6, C) are just
behind the gullets (Fig. 9.6, B) of the blade.

Next set the roller guides (Fig. 9.7, A) as near as possible
to the blade (Fig. 9.7, B) without actually touching. This
is done by unlocking the nut on each side of the guide
adjustment (Fig. 9.5, D). Do not let the roller guides
actually touch the blade as this will adversely affect the life
of the blade.
Finally adjust the blade support roller (Fig. 9.7, A) to be
just clear of the back of the blade (Fig. 9.7, B). Do this by
unlocking the grub screw (Fig. 9.5, D).
When the correct adjustment is reached lock the blade
support roller in position.

10. Drive Belt Adjustment & Speed Change
Adjusting the Drive Belt Tension
Fig. 10.1
CAUTION! Before carrying out any adjustments or
maintenance ensure that the machine is isolated and
disconnected from the electricity supply.
A
Use the belt tensioning handle (Fig. 10.1, A) to adjust the
tension of the drive belt. Rotate the handle anti-clockwise
to increase the tension and clockwise to decrease tension.
As a guide the belt is adequately tensioned when using
the index finger to impart reasonable pressure on the
belt - the belt should not deflect more than 1/4”. But like
tensioning a bandsaw blade this is very subjective and the
best test is in operation, if the belt isn’t slipping or wearing
excessively and there is adequate power being applied to
the bandwheels then the drive belt is tensioned correctly.
Changing the Blade Speed
Fig. 10.2
The BS12 has two blade speeds 820 m/min for wood and
380 m/min for some plastics and acrylics. This machine is
not suitable for cutting metals.
The lower bandwheel has two, integral, multi vee form
pulleys and the motor shaft has a twin multi vee
form pulley.
C
The vee belt (Fig. 10.2, A) passes around the bandwheel
pulley, the motor pulley (Fig. 10.2, B) and the plain tension
roller (Fig. 10.2, C). The belt tension is released and applied
by using the crank handle, this moves the tension roller
and allows the speed to be changed.
A
B
High Speed 802 m/min
For high speed the belt should be fitted to the rear pulley
on both the motor and bandwheel.
Lower Speed 372 m/min
For low speed the belt should be fitted to the front pulley
on both the motor and bandwheel.

11. Connection of the Electricity Supply
Once the machine has been correctly assembled and set up the electricity
supply can be connected.
The machine can only be connected to a single phase supply. Before connecting
the electrical supply ensure that it is the correct voltage, phase and frequency,
and that it has sufficient capacity for the machine. The relevant information can
be found on the rating plate located on the rear of the machine.
Machines supplied for use in the UK are fitted with a BS1363 plug fitted with
a 13 amp fuse. Ensure that you use the appropriate plug for use in other
countries. If the plug fitted to the machine is changed for any reason, the wires
in the mains lead are coloured in accordance with the following code:
Green and Yellow:
Earth
Blue:
Neutral
Brown:
Live
As the colours of the wires in the mains lead may not correspond with the
coloured markings identifying the terminals on your plug, proceed as follows:
The wire coloured green and yellow must be connected to the terminal marked
‘E’ or by the earth symbol ~ or coloured green; or green and yellow.
The wire coloured blue must be connected to the terminal marked ‘N’
coloured black.
The wire coloured brown must be connected to the terminal marked ‘L’ or
coloured red.
Note:
It is important that the machine is effectively earthed.
If in doubt about the connection of the electrical supply consult a qualified
electrician.
RCD (Residual Current Device)
For your additional safety we always recommend the use of an RCD (sometimes
called Residual Current Circuit Breaker or Earth Leakage Circuit Breaker).
The machine must not be connected to a TN-S power supply system. A circuit
breaker (13A) with RCD module (30A) must be installed for supplying electric
power to this machine, in order to protect the user against electrical shock due
to indirect shock.
Connect the main leads to a standard 230V±10% (50Hz+1%Hz) electrical
supply which has devices for protection against under-voltage, over-voltage,
over-current as well as a residual current device (RCD) with maximum residual
current rated at 0.03A, the main connection must have maximum 13A
time-lag fuse.

inner red button on the switch unit.
Note:
Depending on the condition of the electrical mains supply, slight voltage
reductions may occur when the machine is switched on (eg momentary
dimming of a light bulb). If the mains impedance Zmax is <0.459 Ohms
such reductions should not occur. Please contact your local authority if
you require further information.
Replacing the Power Supply Cable
Replacement of the power supply cable should only be done by a
qualified electrician.

• The blade cuts on a continuous down stroke.
Set
Gullet
• Slowly feed the workpiece towards the blade, using only
light pressure whilst letting the blade do the cutting.

• Firmly hold the workpiece and feed it towards the blade slowly, using the push stick and keeping your hands well
away from the blade.
• For best results the blade must be sharp. Damaged or
worn blades should always be replaced.
Tooth

• Select the right blade for the job, depending on the
thickness of the wood and the cut to be
made (Fig. 12.1).
• For straight cutting use the rip fence supplied.
• When cutting shapes, follow the design marked out
by pushing and turning the workpiece evenly. Do not
attempt to turn the workpiece without pushing it, as this
may cause the workpiece to get stuck, or the blade
to bend.
CAUTION! Particular care should be taken towards
the end of the cut as there will be a sudden decrease
in resistance and care must be taken to stop hands
from being thrown into the blade.
Always ensure that your machine is properly maintained
and clean. Before commencing work on an important
project, it is advisable to familiarise yourself with the
operation of the equipment by practising on low value
materials.

Original Instruction Manual | BS12 12” Bandsaw | Version 2.0 | February 2012
12. Operation & Bandsawing Practice - Cont.
Complicated Cutting
Very complicated cuts and small radius curves are the best
accomplished with the aid of pre-drilled holes combined
with a few tangential or radial cuts. This technique will
achieve excellent results without putting undue tension on
the blade and blade guide assembly.
Reversing the Blade Out of a Cut
If at all possible we advise that reversing out of a cut is
avoided. But in situations such as cutting scrolls it may not
be possible to complete a cut. This requires the blade to
be reversed out of the cut. Care is necessary to minimise
damage to the work and blade. When removing large
pieces of material it is advisable to make the shorter cut
last to avoid having to reverse out of the longer cut. When
reversing out of a cut it is advisable to leave the blade
running, but take extreme care not to pull the blade off the
band wheel.
WARNING! In circumstances such as cutting deep or
wet timber, the work piece may close up behind the
blade causing it to stall. In the event that the blade
stalls whilst cutting, ease the work piece backwards
slightly, to release feed pressure from the blade. Allow
the blade to reach full speed before continuing to
feed the work piece in to the blade. If the blade fails
to move when feed pressure is released, immediately
switch off the machine and disconnect the power
supply before attempting to free the blade from the
work piece.
WARNING! If any component of the machine fails
whilst in use or if the blade should break whilst
the machine is running, immediately switch off the
machine and disconnect from the power supply.
Remove the faulty component and replace only
with genuine Record Power replacement parts. Any
electrical components should only be replaced by a
suitably qualified person. To replace a broken blade,
please refer to the section of this manual entitled
“Band saw Blade Set Up”. Always remember to
fully release the blade tension mechanism before
attempting to fit a new blade. If you are in any doubt
about using the machine following a failure or if you
need to order replacement spare parts or blades,
please contact our Technical Department
on 01246 561 520.

Blade Selection (TPI)
The selection of the best blade configuration (see the table below) is
necessary for optimum cutting performance.
• Correct blade choice is primarily dependant on two factors: material
thickness and material type.
• Greater TPI should be selected as material thickness decreases.
• However, if the TPI is too great, the tooth loading will be insufficient to
enable penetration; and cutting. The teeth will also rapidly lose
their sharpness.
• For thicker material a lower TPI should be used otherwise the gullet will
not be sufficient to clear the waste and the blade will stall or burn
the wood.
The accompanying blade selection chart (see the table below) gives
guidance on the TPI that should give the best results when cutting a
variety of material types and thickness. (See the table below) provides
recommendations on selecting the correct blade for a variety of commonly
used materials. If in doubt about any aspects of blade selection contact
Customer Services on 01246 561 520 for assistance.
The table provides a guide to selection only. Exact tooth configurations
are not always available, nor are all blade configurations covered, but the
principles remain the same.
For special applications, custom blades can be supplied please call

Having selected an appropriate
blade for the particular thickness
and type of material to be sawn,
it is essential that the saw blade
is allowed to cut freely by not
applying too much pressure.
• The need for excessive pressure
is likely to be a result of the
incorrect blade selection or a worn
blade and will result in inaccurate
cutting and possibly
blade breakage.
Blade width: 1/2”
Min radius: 21/2”
Blade width: 3/8”
Min radius: 11/16”
Blade width: 1/4”
Min radius: 3/4”
Blade Selection (Width)
• When cutting shapes, the width
of the blade limits the minimum
radius that can be cut.
• If the blade is too wide for the
cutting radius the blade will twist
and possibly jam or break.
• The smaller the radius the
narrower the blade has to be.
The adjacent diagram provides
guidance on the minimum radius
to be cut with the most commonly
used blade widths.

CAUTION! Before carrying out any adjustments or
maintenance ensure that the machine is isolated and
disconnected from the electricity supply.
HAZARD! Take great care when unpacking the
bandsaw blade as they are usually folded and can
spring out very suddenly with great force.
A
Tip:
If the new blade being fitted is a different width to
the one being removed, it is advisable to move back
and slacken off all blade guides before fitting the
new blade as this will make fitting easier. Whenever
a different size blade is fitted the blade guides will
always need re-setting.
Fig. 14.2
A
1. Remove the rip fence and fence rail by unscrewing the
wing nuts (Fig. 14.1, A) located on the underside of
the table.
1.Open the top and bottom bandwheel doors.
2. Turn the blade tension knob to release the blade
tension (Fig. 14.2, A).
3. Remove the bandsaw blade by feeding it through the
slot in the table, upper blade guides & guard and slot in
the spine of the machine taking care not to cut yourself,
wear gloves if necessary.
4. If the new blade being fitted is a different width to the
one being removed, before the new blade is placed
around the bandwheels:
Fig. 14.3
• Adjust the tension wheel to suit the new blade size.
• Place the new blade on the bandwheels.
• Fit the new blade ensuring the blade teeth are pointing
downwards and towards you at the position where the
blade passes through the table.
• Ensure the blade is fully in place on bandwheel, re-apply tension using the tensioning knob.
• Fine adjust the blade tension further if required using the blade tension wheel.

5. If the new blade width is the same as the blade
being removed:
• Fit the new blade ensuring the blade teeth are pointing downwards and towards you at the position where the blade passes through the table.
• Ensuring that the blade is fully in place on bandwheel. Simply re-apply tension using the tensioning knob.
• Fine adjust the blade tension further if required using the
blade tensioning knob.
6. Check the blade tracking on the newly fitted blade by
turning the upper wheel by hand. The blade should run
as close to the centre of the bandwheel as possible. On 1/4", 3/8" and 1/2" blades it may be necessary to
run the blade to rear of the bandwheel (see section 6.2.)
7. If required adjust the tracking using tracking knob
(15) and lock knob to the rear of the upper bandwheel
housing. When the tracking is correct lock the setting
(see section 6.2).
8. Re-set the blade guides (see sections 6.3 & 6.4)
9. Close and lock both the bandwheel doors before re connecting the power supply.
For further information on blade tensioning see section 6.1.
Replacing the Drive Belt
To replace the drive belt (Fig. 14.4, A) simply loosen the
tension on the belt using the tension handwheel. Remove
the lower bandwheel (Fig. 14.4, B) by undoing the circlip
(Fig. 14.4, C) on the hub. Remove the old belt and fit the
new one. Once the drive belt is in place re-fit the lower
bandwheel and tighten the nut. Now tension the drive belt
using the tension handwheel. For further information on
tensioning the drive belt please.

The Blade Guide System
Fig. 14.5
A
In general usage it is advisable to carefully apply silicon
spray to the blade guides to ensure free movement of the
rollers, do not use oil or grease for lubrication as this will
attract dust and cause the rollers to jam. The blade guide
system is a consumable item and depending on usage will
wear and need replacing.
When replacing components on the upper guide assembly
first ensure that the blade is removed. Undo screws
(Fig. 14.5, A) & then remove the whole assembly. Individual
components can then be changed
Once the new components have been changed & the upper
guide assembly refitted the blade should be refitted and
the guides adjusted.
When replacing components on the lower guide assembly
first ensure that the blade is removed. Undo screws
(Fig. 14.6, A) & then remove the blade guard. You are now
able to remove nut (Fig. 14.6, B) & remove the whole
assembly. Individual components can now be changed.

The Table Insert
Fig. 14.8
The table insert on a bandsaw is a consumable item (Fig.
14.8) and will therefore need replacing periodically. This
procedure should be carried out with the bandsaw blade
removed. To replace the table insert simply push the old
insert out from underneath the table and fit the new one
into position.
The Bandwheel Tyres
The bandwheels on this machine have rubber tyres fitted
to the outer rim of the wheel (Fig. 14.9) to protect the set
of the blade when in use, also to provide drive and to stop
the blade slipping. As part of your regular service schedule
inspect the tyres for wear and damage and replace if
necessary. Again this is a consumable part of the bandsaw
and will need replacing periodically depending on usage.
Fig. 14.9
First remove the blade from the bandsaw, then remove
the bandwheel. Gently ease the existing tyre from the rim
taking care not to damage the bandwheel. To fit the new
tyre it is a good idea to heat the tyre first in hot water,
this softens the rubber up and makes it easier to stretch it
over the bandwheel. The tyres before stretching are much
smaller than the bandwheel and a good deal of stretching
is required to make them fit. It is advisable to get help
from a second person who can insert the wheel into the
tyre while it is fully stretched.
The Bandwheel Bearings
The bandwheel bearings are sealed for life units which will
need replacing periodically depending on usage.
To replace the bearings; first ensure that there is no blade
fitted. Now remove the circlip from the hub and remove
the bandwheel (circlip pliers will be required to carry out
this operation), you will notice that there are two separate
bearings fitted in the hub pressed up against each other.
Take a brass drift (or similar) and tap one of the bearings
out, the second bearing should now be able to be
pushed out.
Fig. 14.10
When fitting the new bearings; position by hand in the
wheel hub and tap in until the bearing seats against the
ridge in the casting (Fig. 14.10).

14. Maintenance - Cont.
Cleaning the Table
The table is ground from cast iron and if cared for properly
will provide smooth accurate performance. Obviously
when machining wood a certain amount of resin will be
deposited on the surface, to ensure optimum performance
the table needs to be properly cleaned at regular intervals.
Firstly brush off all loose particles, then wipe clean with
white spirit ensuring that any resin build up is dispersed
and removed. Once the table has been thoroughly cleaned
it can now be treated with CWA195 silicone spray or
wax. If these guidelines are followed the timber will glide
smoothly and accurately across the table.
The Bandwheel Brush
The purpose of this brush is to remove any excess sawdust
and resin from the bandwheel and tyre (Fig. 14.11). This
brush will need adjusting periodically depending on usage.
Before each use inspect the brush and make sure it is
making sufficient contact with the bandwheel to remove
sawdust from the tyre. The brush should be touching but
not applying pressure to the wheel). If it isn’t; loosen the
fixing and adjust accordingly so it makes contact with the
wheel. When the brush cannot be adjusted any nearer
the wheel due to the bristles being worn then it must be
replaced. Periodically the brush may also become clogged
up with resin (this is especially common when cutting a
long run of soft wood) if this occurs this resin must be
scraped off as performance of the brush will be reduced.
