SAFETY WARNINGS
WORK ENVIRONMENT
1. Keep the work area clean and well lit. Cluttered and dark areas invite
accidents.
2. Do not operate power tools in explosive atmospheres, such as in the
presence of flammable liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
3. Keep children and bystanders away while operating a power tool. Anyone
entering the work area must wear personal protective equipment.
Distractions can cause you to lose control and fragments of work or a
broken disc may fly away and cause injury.
4. Store power tools properly when not in use. Abrasive products should be
stored in a dry, secure place out of the reach of children.
5. Please read these instructions carefully and retain for future reference.
ELECTRICAL SAFETY
1. Power tool plugs must match the outlet. Never modify the plug in any way.
Do not use adapter plugs with earthed (grounded) power tools. Unmodified
plugs and matching outlets will reduce the risk of electric shock.
2. Do not expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
3. Do not abuse the cord. Never use the cable for carrying, pulling or
unplugging the power tool. Keep the cable away from heat, oil, sharp
edges or moving parts. Damaged or entangled cables increase the risk of
electric shock.
4. When operating a power tool outdoors, use an extension cable suitable for
outdoor use. Use of a cable suitable for outdoor use reduces the risk of
electric shock.
PERSONAL SAFETY
1. Stay alert, watch what you are doing and use common sense when
operating a power tool. Do not use a power tool while you are tired or
under the influence of drugs, alcohol or medication. A moment of
inattention while operating power tools may result in personal injury.
CAUTION: FAILURE TO FOLLOW THESE PRECAUTIONS COULD RESULT IN
PERSONAL INJURY, AND/OR DAMAGE TO PROPERTY.

2. Use personal protective equipment. Always wear eye protection. Safety
equipment such as dust mask, non-skid safety shoes, hearing protection
and a workshop apron capable of stopping small abrasive or workpiece
fragments.
3. Avoid accidental starting. Ensure the switch is in the off position before
plugging in. Plugging in power tools that have the switch on invites
accidents.
4. Remove any adjusting key or wrench before turning the power tool on. A
wrench or a key left attached to a rotating part of the power tool may
result in personal injury.
5. Do not overreach. Keep proper footing and balance at all times. This
enables better control of the power tool in unexpected situations. Dress
properly. Do not wear loose clothing or jewellery.
6. Keep your hair, clothing and gloves away from moving parts. Loose
clothes, jewellery or long hair can be caught in moving parts. Keep the
work area clean and tidy.
7. Regularly clean the power tool’s air vents. The motor fan will draw dust
inside the housing and accumulation of material could cause electrical
hazards.
8. Avoid operator fatigue. Stop the power tool at regular intervals for a short
break to rest hands and arms.
9. Maintain your tools. Keep all handles and grips dry and clean.
ELECTRICAL SAFETY
1. Position the power cable so that it cannot be inadvertently pulled or
pinched, and where it does not cause a trip hazard.
2. This machine is designed for indoor environments and must not be used for
other purposes.
3. If the machine requires repair, always contact your Clarke dealer. Always
insist on original spare parts. Repairs carried out by unauthorized persons
may be dangerous and invalidate the guarantee.
4. This machine must only be used by adults. Children should not be allowed
to play with this appliance.
5. Do not use extension power cables.
6. Before cleaning or maintenance operations, always unplug the machine
from the power supply.

Parts & Service: 020 8988 7400 / E-mail: [e-mail] or Servi[email protected]om
• The fence can be adjusted for accuracy when parallel to the side of the
blade by loosening the two socket bolts (H). Check the alignment with a
square before tightening the bolts.
ALIGNING THE FENCE WITH THE BLADE
To determine the distance of the
fence from the saw blade, the scale
on the fence guide rail must be set to
line up with the blade.
1. To do this, position the fence so
that it just touches the blade while
it is free to move along the guide
rail.
2. Loosen the guide rail locking
knobs and move the guide rail to
the side until the indicator scale is on ‘Zero’, then re-tighten the knobs
• If the fence is changed to the alternative height, the guide rail will need to
be re-set for that configuration.
USING THE MITRE GAUGE
The mitre gauge is inserted into the
table slot from the front edge.
The mitre gauge can be turned to
60oin both directions.
To set a mitre angle, loosen the lock
handle by turning it counter-
clockwise. Firmly tighten the handle
to secure the mitre gauge in position.
USING THE PUSH STICK
The push-stick serves as an extension
of the operators hand as protection
against accidentally touching the
saw blade.
The push-stick should be used if the
distance between the blade and rip
fence is less than approx 150 mm.
When not in use, the push-stick can
be stored on the hook provided on
the bandsaw frame.
Always replace the push-stick if lost or damaged.
