1. SAFETY INSTRUCTIONS

IMPORTANT: PLEASE READ THESE INSTRUCTIONS CAREFULLY. NOTE THE SAFE OPERATIONAL REQUIREMENTS, WARNINGS AND

CAUTIONS. USE THIS PRODUCT CORRECTLY AND WITH CARE FOR THE PURPOSE FOR WHICH IT IS INTENDED. FAILURE TO DO SO MAY

CAUSE DAMAGE AND/OR PERSONAL INJURY, AND WILL INVALIDATE THE WARRANTY. PLEASE KEEP INSTRUCTIONS SAFE FOR FUTURE USE.

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 and 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 together 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 the appliance

and the safety of the appliance operator. 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, plugs and all electrical connections for wear and damage,

especially power 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. A 13 amp plug

may require a fuse smaller than 13 amps for certain products (subject to 1.1.10. below) 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

bya qualified electrician. 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 live terminal ‘L’.

c) Connect the BLUE neutral wire to the neutral terminal ‘N’.

After wiring, check there are no bare wires, that all wires have been correctly connected, that the cable outer insulation

extends beyond the cable restraint and that the restraint is tight.

Double insulated products are often fitted with live (BROWN) and neutral (BLUE) wires only. Double insulated products are always

marked with his symbol . To re-wire, connect the brown & blue wires as indicated above. DO NOT connect the brown or

blue to the earth terminal.

1.1.10. Some products require more than a 13 amp electrical supply. In such a case, NO plug will be fitted. You must 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 cable on the cable

reel is important. 1.5mm² section cable is a minimum 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, we recommend the use of 2.5mm² section cable.

1.3. SPECIFIC SAW SAFETY RULES

Remove sawdust frequently. Unplug from mains power. Clean out sawdust from interior of saw to prevent potential fire hazard.

Keep riving knife and guard in place and operational, and replace table insert when worn.

Do not fit any other type of saw blade other than the type supplied with the machine.

WARNING! Before each use, check that the saw blade is secure and not worn or damaged.

Use the guard and riving knife on all “through-sawing” operations. Through-sawing operations are those when the blade cuts completely

through the workpiece as in ripping or cross-cutting.

Check workpiece to ensure there are no nails or other items which may foul on the saw blade.

Hold the work firmly against the mitre block or fence.

Only feed the workpiece into the blade against the rotation of the blade.

 Avoid subjecting the saw blade to excessive strain, never force a workpiece. Maintain a controlled adequate progression.

Should the saw blade jam switch the power off immediately to prevent damage to the motor.

TO AVOID WORKPIECE “KICKBACK” (When a workpiece is violently thrown back toward yourself).

a) Keep the blade sharp.

b) Keep rip fence parallel to the saw blade.

c) DO NOT release the workpiece before it is pushed all the way past the saw blade.

d) DO NOT rip work that is twisted or warped or does not have a straight edge to guide along the fence.

Use the push stick for ripping narrow stock. Refer to ripping applications and to the use of push stick in Section 5.3.

Provide adequate support to the rear and sides of the saw table for wide or long workpieces.

 DO NOT use your hands alone to guide the workpiece unless the workpiece is too large to use the guides provided. Otherwise, hold the

work firmly against the mitre or fence to guide work through the saw.

 DO NOT place yourself in an awkward operating position where a sudden slip could cause your hand to move into the cutting blade.

 DO NOT stand or have any part of your body in line with the path of the saw blade, and keep your hands out of the line of the saw blade.

 DO NOT use the fence as a cut-off gauge when cross-cutting.

 DO NOT hold what will become the off-cut (the waste part of workpiece).

WARNING! DO NOT reach behind or over the saw blade with your hand or arms.

WARNING! DO NOT attempt to free a jammed saw blade without first switching off or removing the plug from the mains power supply.

 DO NOT cut metal materials, and substances that may produce toxic dust. Saw must only be used to cut wood or wood type substances.

 DO NOT use solvents to clean plastic parts which may damage them. Use a soft damp cloth only.

3. SPECIFICATIONS & ASSEMBLY

3.1 MOUNTING THE SAW. If the saw is to be bolted to a workbench you should ensure that it is

in the most convenient position for use with sufficient clearance from nearby walls and other

features to allow you to handle and cut the largest pieces of sheet and timber you require.

3.1.1 If the saw is not to be permanently fixed in one location it should be mounted to a stout piece

of board in order to give the saw stability in operation. The board should be not less than

450 x 600mm and be at least 15mm thick. To mount the saw, drill four 5mm holes at the

dimensions shown shown in fig.A. or place the saw onto the board and mark the fixing

positions through the mounting holes.

3.1.2 Use 4mm bolts to fix the saw to the board. Tighten the bolts progressively to avoid distorting

the saw frame. Do not over tighten the bolts. Before using the saw ensure that it is securely

clamped to a strong workbench with at least two ‘G’cramps. Check that these remain tight at

all times whilst using the saw. Ensure that the work area has adequate lighting.

 WARNING! ENSURE THE SAW IS NOT CONNECTED TO THE MAINS POWER BEFORE

COMMENCING ASSEMBLY.

3.2 Rip fence assembly and adjustment. ( See fig.2 item 4 ) The saw is supplied with a rip fence cutting guide which is essential to

achieve a straight cut when cutting in the same direction as the grain of the wood.

3.2.1 To assemble the fence to the support table first loosen the clamps at either end of the fence by turning the clamping knobs ( See item

9 in figs.1 & 2 ) anticlockwise. The fence can be positioned on either side of the blade to suit the size and width of the timber being

cut.

3.2.2 Place the guide at one side of the table, parallel to the blade, and slide the clamps onto the table so that the loose part of each clamp

is on the inside of the front and back edges of the table.

3.2.3 Position the guide at the required distance from the blade using the two scales inset into the surface of the table. Each end of the

guide must be set on the scale at the same distance from the surface of the blade. This is essential to ensure that the guide is parallel

to the blade. Double check this before proceeding to cut.

3.3 Mitre block. A mitre block is supplied to aid cutting at 90° and 45° to the blade. When required the mitre block should slide onto the

lower part of the rip fence guide as shown in fig.2 item 3.

WARNING! ensure saw is switched off & disconnect from the mains power before making adjustments or setting saw.

4.1 ON/OFF SWITCH (See fig.1 item 7)

For normal operation push the “l“ button for ON and the “0“ for OFF. The saw is fitted with an ON/OFF switch of the ‘no volt release’

type. This means that if the power fails or is disconnected whilst the machine is in use, the machine will not restart automatically when

the power is restored. In this situation it will be necessary to restart the saw by pressing the “l“ for ON button again.

4.2 DUST EXTRACTION PORT.

WARNING! Wood dust can be harmful to health by inhalation and skin contact and concentrations of small dust particles in the air can

form an explosive mixture. Ensure there is adequate ventilation.

The saw is fitted with a dust extraction port (See fig.2 item 8). For safe operation we recommend that a suitable dust extraction device

or vacuum cleaner is connected during operation. Never allow an excess of sawdust to accumulate on the saw, especially around the

motor.

WARNING! Excessive sawdust build up around the motor could possibly ignite causing injury to yourself and damage to the saw and

its surroundings.

4.3 BLADE GUARD (See figs.1&2 item 2)

WARNING! Ensure saw is switched off & disconnected from

the mains power before making any adjustments.

The blade guard is designed to be self closing. When not in use

the front edge of the guard should be resting on the table. As

the workpiece is pushed towards the blade the sloping front

edges of the guard will ride up and over the workpiece. As the

workpiece moves past the blade the guard will drop down

again. (The guard retaining knob should not be done up tight as

this would restrict the automatic movement of the guard). On

the right hand side of the guard there is a sliding plate which

offers additional protection when the blade is tilted (See fig.3)

WARNING! The blade guard must be in place during all

cutting operations. The saw is not designed to produce

through grooves,

stopped grooves or rebating. Do not attempt to modify or adapt

the saw in any way or use any other manufacturers

accessories.

4.4 BLADE TILT CONTROL

The blade can be tilted to cut any angle up to 45° for both rip

and cross cutting. Firstly loosen the two blade tilt locking knobs.

(See figs.1&2 item 10) To tilt the blade begin to wind the blade

tilt handle (See fig.1 item 6) anticlockwise until the blade

reaches the desired angle which can be read from the angle

scales adjacent to each locking knob. Then re-tighten both locking knobs. See tilted blade in fig.3.

5.4. RIP SAWING.

WARNING! The same safety precautions apply as stated at the beginning of chapter 5.

Ripping is when a board or similar workpiece is held against the rip fence and cut

along the length (See fig.7). The fence is used to position and guide the workpiece

through the saw. The workpiece is laid flat on the saw table with one edge held tightly

against the rip fence. Behind the blade is the riving knife which prevents the saw cut

from closing and binding on the blade. Proceed as follows:

5.4.1. Fit the rip fence at the required width of cut from the blade and tighten the clamp at

each end ensuring that the rip fence is parallel to the blade.

5.4.2. Before starting consider how you will handle the workpiece and the off-cut when

ripping is complete. Depending on the size and type of work, off-cuts and work

may remain on the table, or, tilt up slightly and be caught by the rear end of the

blade guard, or, fall to the floor. We recommend a support is provided at the rear of

the saw table to keep the work and off-cut from falling. Alternatively the feed may

continue to the end of the table, after which the workpiece may be lifted and brought

back along the outside edge of the fence back towards yourself. Off-cuts that remain

on the table must not be touched until the saw blade has completely stopped.

5.4.3. Check all is ready and blade guard is down. Plug saw into the mains power supply and switch on.

5. OPERATING INSTRUCTIONS

WARNING! As with all power tools, there are potential hazards involved with the operation and use of this saw. It is therefore vital to

ensure you have read, understood and apply all the safety instructions in chapter 1. Familiarise yourself again with the specific saw

safety rules for each step of the following operation. Failure to do so may cause serious damage or personal injury and may

invalidate your warranty. Disconnect the saw from the mains power before adjusting or setting accessories. Ensure all locks, bolt,

and nuts are secure and the blade is in good condition and correctly positioned. ALWAYS USE the saw guard in down position

before turning the saw blade on. Wear approved safety eye protection.

5.1 DUTY CYCLE. To prolong the service life of the machine always rest the saw for ten minutes after every 30 minutes of continuous

use.

5.2. KICKBACK. Kickback is when a workpiece is violently thrown back toward yourself. This effect can generally be avoided by observing

the following points.

a) Keep the blade sharp.

b) Keep rip fence parallel to the saw blade.

c) DO NOT release the workpiece before it is pushed all the way past the saw blade.

d) DO NOT rip work that is twisted or warped or does not have a straight edge to guide along the fence.

e) Ensure that the riving knife is always in line with the blade. (See section 6.4)

5.3. CROSS CUTTING

DO NOT stand or have any part of your body in line with the path of the saw blade, and keep your hands out of the line of the saw

blade.

5.3.1 Clearly mark out the wood to be cut.

5.3.2 When you have completed the cross cut, the waste off-cut will be un-supported and may remain on the saw table, or may fall from the

table. Before starting therefore, consider how you will handle the off-cut.

5.3.3 When cross cutting shorter lengths of wood the mitre block can be employed to control cuts at 90Oto the blade (See fig.4) and 45°to

the blade (See fig.5). (The mitre block can only be used on the left side of the blade).

WARNING! When using the mitre block, the rip fence guide should not be used as a length cutting gauge. Therefore the

distance from the blade to the rip fence guide should be at least 8mm longer than the length of timber to be cut. Ensure that the rip

fence is parallel to the blade and firmly clamped at each end.

5.3.4 Slide the mitre block onto the lower part of the rip fence guide as shown in fig.2 item 3. Place the workpiece against the mitre block

and align the marked out line on the wood with the ‘O’ mark on the scale at the front edge of the table. Advance both the block and

the workpiece towards the saw blade until it makes contact with the blade guard.

5.3.5. Plug the saw into the mains power supply and switch the saw on.

5.3.6 Slowly move the workpiece forward so that the blade guard rises and the workpiece moves into the rotating blade. Continue holding

work firmly whilst passing it completely through blade and the piece is cut in two.

5.3.7 Before drawing the workpiece back towards yourself, move it slightly to the side so that it is clear of the saw blade.

WARNING! DO NOT attempt to pick up a short off-cut before the saw blade has completely stopped.

5.3.8 If the workpiece overhangs the table remove the rip fence and mitre block and proceed as shown in fig.6. As previously stated,

consideration of how to handle larger workpieces and the off cuts should be given before commencing cutting. The marked out line on

the workpiece should be carefully aligned with the blade before switching on.

5.3.9 Switch on the saw and move the workpiece under the blade guard and slowly and evenly into the rotating blade keeping an eye on the

alignment between the blade and the line marked on the timber. Once the blade begins to cut into the timber the cut becomes

self aligning with the blade and on no account should you try to alter the line of cut. Proceed with slow, even pressure allowing

the blade to do the cutting until the cut is complete.

6. MAINTENANCE

 WARNING! Disconnect the saw from the mains power before changing

accessories, servicing or performing any maintenance.

6.1 AFTER EACH USE

Saw dust must be removed from the machine. If a dust extraction device has

not been used remove the side cover from the blade and use a vacuum cleaner

to ensure that all dust has been removed.

6.2 BLADE INSPECTION

ENSURE SAW IS DISCONNECTED FROM THE MAINS POWER SUPPLY

Inspect the blade before and after each use. If the blade is blunt or damaged in

any way fit a new blade of the correct size and type.

6.3 TO CHANGE THE BLADE

ENSURE SAW IS DISCONNECTED FROM THE MAINS POWER SUPPLY

6.3.1 To change the blade it will be necessary to remove the cover from the blade

housing below the table. Undo the five retaining screws and lift off the cover.

6.3.2 Place a piece of wood onto the front of the table and slide it under one of the

blade teeth as shown in fig.8. Place a spanner onto the retaining nut and loosen

it in an anticlockwise direction. Remove the nut and the outer flange.

6.3.3 Wear protective gloves when handling the blade. Angle the bottom edge of the

blade outwards and remove the blade in a downwards direction.

6.3.4 Insert the new blade ensuring that the teeth face downwards when viewed from

the front of the table. Replace the outer flange and nut. Hold the blade firmly

with your gloved hand whilst tightening the centre nut.

6.3.5 Place the cover on the blade housing and fix it with the five retaining screws.

6.4 CHECKING THE ALIGNMENT OF THE RIVING KNIFE

6.4.1 The riving knife should always be directly in line with the blade and spaced

away from it by 2 to 5mm. Check the alignment on a regular basis and adjust if

necessary.

6.4.2 To adjust both the alignment with the blade and the distance from it, remove the

table insert by undoing the six screws holding it in place and lift off.

6.4.3 Slacken the two screws indicated in fig.9 until the knife is only just loose and

slide it forwards or backwards to set the distance between the knife and the

blade. Then place a straight edge alternately either side of the blade to check

that the knife is in alignment. ( Rest the straight edge on the surface of the

blade without it coming into contact with the teeth tips.) Adjust if necessary and

then lightly tighten the screws. Recheck the alignment and when satisfied fully

tighten.

6.4.4 Replace the table insert and fix in place with the six screws.

5.4.4. Ripping a workpiece more than 100mm (4”) wide.

DO NOT stand or have any part of your body in line with the path of the saw blade, and keep your hands out of the line of the saw blade.

a)Hold the workpiece firmly against the fence and the table and feed the work under the blade guard.

b)Continue holding the work firmly with both hands pushing it along the fence and into the saw blade (fig.6).

c)Continue to gradually feed the workpiece through the saw blade keeping your hands away from the blade guard.

d)Pass the work completely through the saw blade and to the rear of the saw table.

e)Once the cut is complete handle the workpiece and off-cut according to 5.2.2.

5.4.5. Ripping a workpiece less than 100mm (4”) wide.

If work is less than 100mm wide, use a push stick to feed work forward (See fig.7).
