1.1. ELECTRICAL SAFETY. p
p
WARNING! It is the users responsibility to read, understand and comply with the following:
You must check all electrical equipment and appliances to ensure they are safe before using. You must inspect power supply leads, plugs and
all electrical connections for wear or damage. You must ensure the risk of electric shock is minimised by the installation of appropriate safety
devices. An RCCB (Residual Current Circuit Breaker) should be incorporated in the main distribution board. We also recommend that an RCD
(Residual Current Device) is used with all electrical products. It is particularly important to use an RCD with portable products that are plugged
into an electrical supply not protected by an RCCB. If in doubt consult a qualified electrician. You may obtain a Residual Current Device by
contacting your Sealey dealer. You must also read and understand the following instructions concerning electrical safety.
1.1.1. The Electricity At Work Act 1989 requires all portable electrical appliances, if used on business premises, to be tested by
a qualified electrician, using a Portable Appliance Tester (PAT), at least once a year.
1.1.2. The Health & Safety at Work Act 1974 makes owners of electrical appliances responsible for the safe condition of those appliances,
and the safety of appliance operators. If in any doubt about electrical safety, contact a qualified electrician.
1.1.3. Ensure the insulation on all cables and the product itself is safe before connecting to the mains power supply.
See 1.1.1. & 1.1.2. above and use a Portable Appliance Tester (PAT).
1.1.4. Ensure that cables are always protected against short circuit and overload.
1.1.5. Regularly inspect power supply leads and plugs for wear or damage and connections to ensure that none is loose.
1.1.6. Important: Ensure the voltage marked on the product is the same as the electrical power supply
to be used, and check that plugs are fitted with the correct capacity fuse. A13 amp plug may require
a fuse smaller than 13 amps for certain products - see fuse rating at right.
1.1.7. DO NOT pull or carry the powered appliance by its power supply lead.
1.1.8. DO NOT pull power plugs from sockets by the power cable.
1.1.9. DO NOT use worn or damage leads, plugs or connections. Immediately replace or have repaired by
a qualified electrician. Where a U.K. 3 pin plug with ASTA/BS approval is fitted, in case of damage, cut off
and fit a new plug according to the following instructions (discard old plug safely).
(UK only - see diagram at right). Ensure the unit is correctly earthed via a three-pin plug.
a) Connect the GREEN/YELLOW earth wire to the earth terminal E.
b) Connect the BROWN live wire to the live terminal L.
c) Connect the BLUE neutral wire to the neutral terminal N.
d) After wiring, check there are no bare wires, that all wires have been correctly
connected, that the cable outer insulation extends past the cable restraint and that the cable restraint is tight.
Double insulated products are often fitted with live (BROWN) and neutral (BLUE) wires only. Double insulated products are always marked with
this symbol . To re-wire, connect the brown & blue wires as indicated above. DO NOT connect the brown or blue wires to the earth terminal.
1.1.10. NOTE: If this product requires more than a 13 amp electrical supply, then NO plug is fitted. You must therefore contact a qualified electrician to
ensure a 30 amp fused supply is available. We recommend you discuss the installation of a industrial round pin plug and socket with your electrician.
1.1.11. Cable extension reels. When a cable extension reel is used it should be fully unwound before connection. A cable reel with an RCD
fitted is recommended since any product which is plugged into the cable reel will be protected. The section of the cores in the cable
is important and should be at least 1.5mm2, but to be absolutely sure that the capacity of the cable reel is suitable for this product and
for others that may be used in the other output sockets, the use of 2.5mm2section is recommended.

SM353CE.V2 -1 -280904
5. ADJUSTMENTS
p p
WARNING! Before following any of the steps below ensure the bandsaw is switched off, isolated from the mains power
supply and at a complete standstill. Failure to comply with this instruction can result in serious injury.
5.1. Blade and speed selection
5.1.1. Refer to Section 2 for the recommended setup for cutting various materials.
5.1.2. Agood rule for blade selection is that three teeth should always be in contact with the workpiece, therefore, the thinner the work piece,
the more teeth the blade should have.
5.2. To adjust blade speed
5.2.1. Disconnect the machine from the power supply.
5.2.2. Loosen the wing nut on the pulley guard then lift up and swing the guard to the front of the machine.
5.2.3. Release tension on the belt by turning the tension lock knob counter-clockwise and letting the motor swing forward.
5.2.4. Shift the belt to the desired grooves on the pulleys. Adjust the belt tension by pulling the motor plate back until correct tension is
obtained then tighten the tension lock knob.
5.2.5. Close the cover guard.
5.3. To change blade and adjust tension
Caution: Blade teeth are sharp, handle with care.
NOTE: Proper blade tension is very important to the safe and efficient running of the bandsaw. The correct tension for the
SM353CE.V2 is between 700 to 900 kg as measured with a blade tension gauge.
NOTE: The teeth must be pointing in the correct direction (indicated on the label found on the saw arm).
5.3.1. Raise saw frame to the vertical position and close the feed control valve by turning clockwise as far as it will go (Do not overtighten).
5.3.2. Open both wheel covers and clean the swarf out of the machine.
5.3.3. Release blade tension by turning the blade tension handwheel counter-clockwise.
5.3.4. Slide the left blade guide arm to the right as far as it will go.
5.3.5. Remove the blade from both wheels and out of each blade guide.
5.3.6. Install the new blade, (teeth pointing down) on the blade wheels and through the upper blade guide, working all the way up between
the blade guide bearings with the back of the blade against the back-up bearing.
5.3.7. Put light tension on the blade and work onto both wheels. (Ensure the back of the blade is against the wheel flanges of both wheels).
5.3.8. Adjust blade to the final tension. Proper tension is achieved when the pointer is on the left mark of the blade tension scale behind
the idle wheel.
5.3.9. Connect the machine to the power supply and turn it on and off two to three times to ensure the blade is seated and tracking properly.
When finished close the wheel covers.
5.4. Hydraulic feed adjustment
5.4.1. Adjust the hydraulic feed by turning the knob situated on the hydraulic cylinder.
Anti-clockwise will increase the feed rate, clockwise will decrease it.
5.4.2. To stop the flow of hydraulic fluid, turn off the hydraulic valve.
5.5. To adjust the blade guides
5.5.1. Loosen the adjusting knob on each blade guide and slide guide assemblies as close as possible to each side of the workpiece and re-
tighten.
5.6. To adjust the blade guide bearings
5.6.1. Raise the saw arm to a vertical position and close the hydraulic valve.
5.6.2. Loosen the hex. cap screw on the guide assembly and adjust the rear bearing to 0.025 mm from the blade.
5.6.3. Loosen lock nut and turn the front bearing eccentric so that bearing is snug with the blade. The blade should still
move up and down freely if grasped. Repeat the procedure for the other guide assembly.

5.8. To adjust blade tracking
NOTE: Blade tracking is factory set and should not require adjustment. However, if it does become necessary, proceed as follows:
5.8.1. Run saw for a short time and then switch off.
5.8.2. Raise saw arm, open blade cover and check blade-to-wheel relationship (tracking). Rear edge of blade should be very close to, but
not hard against, the wheel flanges.
5.8.3. If inspection indicates that adjustment is required tighten or loosen the screw (fig.1.A) until it tracks properly.
5.8.4. Having made a small adjustment close the blade cover and run the saw for a short time.
5.8.5. Switch saw off, open blade cover and check tracking. Repeat adjustment procedure if necessary.
