1.1. ELECTRICAL SAFETY.  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 are 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.

A 13Amp plug may require a fuse smaller than 13Amps 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 13Amp electrical supply, then NO plug is fitted. You must therefore contact a qualified

electrician to ensure a 30Amp 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 2.5mm² section is recommended.

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.

6.4.1. Replace the brush as soon as it becomes worn or damaged or blade life will be significantly shortened.

5.7. ADJUSTING THE VICE.

NOTE: Do not adjust the vice or load/unload any material while the saw is running. The vice can be adjusted

to hold the workpiece at angles between 0°and 45°.

5.7.1. To position the moveable vice jaw, turn the vice handwheel counter-clockwise half a turn and move the vice jaw to the desired position

and tighten using hand wheel.

5.7.2. Vice can be adjusted to cut any angle from 0° to 45° by loosening the two bolts on each vice jaw. Position the jaw to the desired angle

and tighten the bolts

5.7.3. When cutting at an angle, it is necessary to move the right vice jaw to the left until the workpiece and the right hand vice jaw are clear

of the right hand guide arm.

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.
