General Instructions for 230V Machines

Good Working Practices/Safety

The following suggestions will enable you to observe good working practices, keep yourself and fellow workers safe and maintain your tools and equipment in good working order.

not use any solvents or cleaners as these may cause damage to any plastic parts or to the electrical components. Keep the work area as uncluttered as is practical, this includes personnel as well as material.

WARNING! KEEP TOOLS AND

EQUIPMENT OUT OF THE

REACH OF YOUNG CHILDREN

Primary Precautions

This machine is supplied with a moulded 13 Amp.

Plug and 3 core power cable. Before using the machine inspect the cable and the plug to make sure that neither are damaged. If any damage is visible have the tool inspected/repaired by a suitably qualified person. If it is necessary to replace the plug, it is preferable to use an ‘unbreakable’ type that will resist damage on site. Only use a 13 Amp plug and make sure the cable clamp is tightened securely. Fuse as required. If extension leads are to be used, carry out the same safety checks on them and ensure that they are correctly rated to safely supply the current that is required for your machine.

UNDER NO CIRCUMSTANCES

SHOULD CHILDREN BE

ALLOWED IN WORK AREAS.

It is good practice to leave the machine unplugged until work is about to commence, also make sure to unplug the machine when it is not in use or unattended. Always disconnect by pulling on the plug body and not the cable. Once you are ready to commence work, remove all tools used in the setting operations (if any) and place safely out of the way.

Re-connect the machine.

Carry out a final “tightness” check e.g. guide fence, table tilt, etc., check that the ‘cutting path’ (in this case the path that the work piece will travel) is unobstructed.

Make sure you are comfortable before you start work;balanced, not reaching etc.

Work Place/Environment

Make sure when the machine is placed that it sits firmly on the floor; that it does not rock and is sufficiently clear of adjacent obstacles so that cutting operations will not be impeded. Check you have adequate clearance both in front of and behind the machine when cutting long stuff. If you are liable to be processing unwieldy or awkward work pieces, it is suggested that you consider fastening the machine down to the floor.

If the work you are carrying out is liable to generate flying grit, dust or chips wear the appropriate safety clothing, goggles, gloves, masks etc. If the work operation appears to be excessively noisy, wear ear-defenders. If you wear your hair in a long style, wearing a cap, safety helmet, hair net, even a sweatband, will minimise the possibility of your hair being caught up in the rotating parts of the tool.

Likewise, consideration should be given to the removal of rings and wristwatches, if these are liable to be a ‘snag’ hazard. Consideration should also be given to nonslip footwear, etc.

The machine is not designed for sub-aqua operation, do not use when or where it is liable to get wet. If the machine is set up in the open, and it starts to rain

(unusual though this would be in U.K.), cover it up or move it into the dry. If the machine has got wet; dry it off as soon as possible with a cloth or paper towel.

Do not use 230V a.c. powered machines anywhere within a site area that is flooded or puddled and do not trail extension cables across wet areas. Keep the machines clean; it will enable you to more easily see any damage that may have occurred. Clean the machine with a damp soapy cloth if needs be, do

Do not work with cutting tools of any description if you are tired, your attention is wandering or you are being subjected to distraction. A deep cut, a lost fingertip or worse; is not worth it!

Do not use this machine within the designated safety areas of flammable liquid stores or in areas where there may be volatile gases. There are very expensive, very specialised machines for working in these areas,

THIS IS NOT ONE OF THEM.

Assembly

Your saw is packed in the box partially assembled.

Please make careful note of the positions of the various components if you have cause to disassemble whilst putting the machine together.

Take all the easily removable items out of the box, tip the box up so that the base of the saw is to the ground; remove all the polystyrene packaging from around the saw (open both sides of the box?) then

“corner walk” the saw out of the box.

If this is still awkward, split the top of the box, fold the box material flat on the floor and “wriggle” the saw off the cardboard. The best method of moving the saw is with a ‘hug’ lift through the neck of the saw, holding the saw back against your body and lifting by straightening your legs.

Assembling the Saw

Lift the saw on to the completed cabinet and secure using the 4 No. M8x40 bolts. Insert the bolts through the base of the saw, through the floor stand and fit the washers and nuts on the underside.

The saw table can be fitted without removing the blade. However, if you would feel more comfortable not having to manoeuvre the table around the blade, remove the blade by opening the top and bottom covers release the tension on the blade by backing off the tensioning knob see fig 1 on page 11, and remove the blade, taking care as it is manoeuvred clear of the guides and the safety guards.

NOTE: If you are going to remove the blade, prior to this you must check and, if necessary, set the

lower blade guide assembly about the blade.

The assembly is mounted in a small housing that is bolted to the main frame. It is locked in position by a hex socket grub screw that is extremely difficult to access when the table is fitted. Check that the assembly is set evenly about the blade.

Fitting the saw table

1. Remove the table fence and fence guide rail, see figs D and E.

2. Manoeuvre the table carefully around the blade (if still fitted). Balance the table on the edge of the tilt housing. The securing bolt for the tilt mechanism (an

M8x50 coach bolt) is pre-fitted into the tilt quadrant.

Remove the butterfly nut and the washer and fit the tilt quadrant into the tilt housing. Ensure that the bolt is correctly inserted through the slot and that the little rib cast on the tilt housing corresponds to the groove in the tilt quadrant. Check that the square under the bolt head is correctly located in its recess in the casting and refit the washer and the butterfly nut, see figs A,B & C.

cover doors There are interlocks fitted to both doors so that the machine cannot operate if either door is left open.

Upper saw

wheel

The upper saw wheel is mounted on double bearings on an axle that is mounted to a tilting plate to provide the fore and aft tilt movement that controls the blade tracking. The tilting plate is hinged to a yoke. The extended ends of the hinge pin also act as guides in slots in a bracket mounted in the rear of the upper saw wheel compartment. The yoke is driven up or down allowing increasing or decreasing of the blade tension). The saw wheel is fitted with a rubber tyre to give better grip to the saw blade and smoother running. It also allows the blade to be tracked in the centre of the wheel; unlike the bad old days when the blade had to be tracked off the front edge of the wheel to safeguard the teeth.

Blade tensioning The blade tensioning knob, at the top of the machine, has an anchored threaded

knob tube connected to it. A bolt passing through the shoulder of the yoke is threaded into the tube. As the knob is turned, so the bolt (and the yoke) is moved up or down and tensions or de-tensions the blade.

Upper blade The upper blade guide assembly mounts the two side bearings and the rear thrust

guide and guard bearing that keep the blade stable (straight and untwisted) above the table during the sawing operation. The guard is an integral part of the guide mounting leg to which the guide assembly is bolted so it is always in place when the guide is raised or lowered to its working position.

Upper blade

guide height

The upper blade guide height clamp is a butterfly nut and coach bolt arrangement that clamps through the guide mounting leg and the main clamp saw frame. So, loose

it will allow the mounting guide leg to be moved up and down; tightened it will clamp the leg in position against the frame.

Saw table, tilt

assembly and

scale

The saw table is mounted on the tilt quadrant which is, in turn, mounted in the quadrant housing and secured via a coach bolt and butterfly nut arrangement.

Loosening the butterfly nut allows the table to be tilted up to 45 degrees clockwise

There is a hole in the frame under the table, into which a bolt with a pair of lock nuts could be fitted to act as a preset stop when bringing the table back to the level position.

Without this bolt fitted the table can be tilted to 5 degrees anti-clockwise. There is a scale and pointer attached to the rear of the quadrant and the housing to measure the angle to which the table has been tilted. There is a slot machined in the table to accept the slide of the mitre fence. There is also a machined recess into which a Measuring Scale

Decal is fitted.

Saw table insert The saw table insert fits into the round recessed groove in the centre of the table.

It not only fills the round void, it also supports the work piece below the saw in order to minimise ‘breakout’ from the saw cut. The table insert that is supplied is for general

work and, as such, has a fairly wide slot to allow the fibre strands from general redwoods and whitewoods to be carried through by the saw blade. Alternative table inserts with much narrower slots should be made when carrying out very fine work, where the breakout must be kept to a minimum.

guide

Guide fence

The lower blade guide assembly is mounted on the main saw frame below the table, it mounts two side guide bearings that help to keep the blade stable

(straight and untwisted) below the table during the sawing operation.

The guide fence is mounted over the front and rear edge of the table. It is clamped in position by the lever handle protruding from the front edge of the guide.

The clamping action is such that both the front and rear of the guide are clamped to the table, ensuring that the guide fence is held rigidly during the cutting operation.

Table stabilising When the table was cast it was a pretty stable lump, however, weathering,

bolt and butterfly machining, drilling and boring etc set up varying stresses in the table which, if

nut given the opportunity, (like with a long slot cut across more than half its width) will cause the table to ‘move’. To counteract this possibility a small housing is machined at the front of the slot into which the stabilising bolt is fitted and clamped with the butterfly nut. This ensures that the two most vulnerable parts of the casting are clamped together in a single plane, to prevent warping and twisting (Unseen).

Mitre fence The mitre fence slide can be engaged in the slot in the saw table, and acts as an

X-feed device, which will enable any angle from right to 45 degrees left or right to be cut with the saw.

Tracking control The tracking control star knob, at the rear of the top compartment, is connected

star knob to a threaded rod that is engaged in a threaded hole in the mounting bracket of the upper saw wheel axle assembly. The end of the rod pushes against the lower end of the hinged tilting plate that carries the upper saw wheel axle. Driving the rod in or out will cause the plate to tilt, and by association, the upper saw wheel, thus enabling the blade to be ‘tracked’. The tilting plate is kept in contact with the end of the threaded rod by the tension on the saw blade, the downward ‘pull’. It should be self-evident therefore, that the blade can only be ‘tracked’ whilst it is in tension.

Tracking control

A butterfly nut that locks the tracking control in position once correct tracking

lock has been established.

Lower saw

wheel

The lower saw wheel and integral pulley wheel is likewise mounted on double

bearings, onto an axle that is housed in an adjusting ‘box trap’ mounting. This box trap is used to set the Lower Saw Wheel to DATUM. It is the base parameter that the rest of the saw is set against. It is highly recommended that, except in the most dire of circumstances, you do not alter the factory setting.

Motor clamping The drive belt is tensioned by turning the motor against a fixed point, pulling the

bolt slot

belt tight and then locking the motor in position with its clamping bolt. During the turning operation the clamping bolt moves within the slot that is machined into the motor mounting flange plate.

Tensioning and tracking the blade

Make sure both top and bottom blade guides are well clear of the blade.

Open the front covers fully, giving good access to the top compartment of the saw and good visibility into the bottom compartment, see fig 03. For tracking the blade first adjust all bearing guides so that there well clear of the blade. Check that the blade is sitting approximately in the middle of the wheels, see fig 15.

Apply some tension to the blade by turning the tensioning wheel clockwise. Spin the top wheel by hand, and check that the blade remains centrally on the tyre, see fig 16. If it does not, loosen the tracking control lock and adjust the tracking by turning the tracking control at the rear of the upper saw wheel compartment, see fig 17. Viewed directly onto the tracking control wheel, turning clockwise should cause the blade to track to the rear of the tyre, anti-clockwise to the front, (DO NOT make large

adjustments).

Spin the top wheel again, check again. Continue until the blade tracks in the centre of the tyres with no appreciable to and fro movement. Tension the blade fully. A side ways push of about 7-8 lbs(3+kgs) in the middle of the blade should allow a 1/4” (6.5mm) distension. Check the tracking again, adjust if necessary. Check that the drive belt is tensioned correctly. If it is slack, apply tension as follows:- loosen the pivot bolt on motor mounting flange plate and turn the motor away from the saw wheel pulley.

When the belt is under tension, tighten the pivot clamping bolt to hold the motor in position, see fig

18. Do not overtighten.

Connect the power to the machine. Stand clear and start the saw, check that the saw is running smoothly,

(no thumps, bumps,knocking or excessive vibration) and the blade appears to be tracking correctly (in one place). You can check this by holding a marker, e.g. a pencil, close to the back of the blade (approach from the back of the blade only) and check that the gap remains constant. If it doesn’t, adjust the tracking until it does. If you adjust the tracking with the saw

that the blade is perpendicular to the table. If it is not, try resetting the table.

If it is still not correct, loosen the locking nut and adjust the bolt until perpendicularity is achieved, see fig 19. Tighten the lock nut and then re-check. When you are satisfied that the table is set correctly, check that the pointer of the tilt gauge reads zero, if not, adjust it, see fig 21.

Fig 21

Checking the table is square

If the preset table stop has been fitted, proceed as follows:-

Loosen the butterfly nut clamping the tilt mechanism, see fig 04, and turn the table hard against its stop. This is a bolt with a lock nut screwed into the underside of the table, see fig 19, the head of the bolt has a rubber foot that acts as a stop when it strikes the machine frame. Tighten the butterfly nut.

When all adjustments have been made, recheck that when the blade is pressed back against the thrust bearing, both the upper and lower side guides are still behind the teeth of the saw. When all adjustments are complete replace the table insert.

Re-connect the power, switch the saw on, allow to run for several minutes, check that the blade is still tracking correctly, there is no excessive vibration, etc.

Switch off. The saw is ready to be used.

Operating Instructions

1. Make sure you have read and fully understood the general instructions and safety precautions that are printed in the preceding pages of this manual.

embedded in the material you are about to cut.

5. Check that all accessories, tools etc., that have been used to set the machine up, are removed and set carefully aside or stowed away correctly.

2. Before connecting the machine to the supply; check the tool for obvious signs of damage, paying particular attention to the plug and the power cable.

Rectify or have rectified any damage you discover.

Check that the blade you are using is the correct one for the job in hand. Change the blade if necessary.

Check the blade is not damaged; is clean, sharp, tracks properly and is correctly tensioned.

6. Ensure the machine is switched off. Plug the power cable into a correctly rated switched socket outlet.

If extension leads are being used, check these for damage, do not use if damaged; if you are working outside, check that any extension cables in use are rated for outside work. Switch on. Allow the saw to run up to speed.

3. Set the upper blade guide to approximately 12mm

(1/2”) above the height of the work piece.

4. Check, especially on site, that there are no foreign objects e.g. old nails, screws, small stones etc.

21

7. Make sure that the material you are about to cut is within the machine capacity, and the cut you are about to make is within the blades’ capabilities. e.g.

Do not try to cut a 1” radius curve using a 5/8” blade.

Continues Over...

Operating Instructions

8. Make sure the blade is not in contact with the material when you start the saw. Start the cutting operation.

Do not try to cut too quickly; the correct cutting speed, if one could be so precise, would never see the blade pushed back against the thrust bearing.

The saw would cut and clear the saw line at the rate the work piece was fed into it. If you notice that you require more and more pressure to effect the cut, and the blade is in continual contact with the thrust bearing, the chances are the blade is becoming blunt.

Check and change if necessary.

Do not let go of the work piece; if you have to change your grip, make sure one hand is holding the material at all times.

9. If you are cutting long pieces of material think about sawing cutouts (i.e. a saw cut from the edge of the material to the saw line) along the saw line so that you can discard the off cuts as you progress down the saw line. find something to use as a sacrificial carrier and mount the work piece on it with double sided tape, or similar.

12. Remember to check the blade tension after a new blade has been ‘working’ for 30-60 mins. The blade will ‘stretch’ slightly when new.

13. Do not release the tension on the saw blade when work is complete. The blades and the main saw frame do not respond kindly to frequent large changes in stress and tension. Only release the tension to change the blade or if the blade is to be removed because the machine is to be ‘mothballed’ for a lengthy time period. The blade in tension over a long period of non-use will cause the tyres to develop ‘flat’ spots. Open the saw cut, either by pulling apart or driving a wedge in close to the back

WARNING! IF THE SAW JAMS!

SWITCH OFF IMMEDIATELY.

10. Observe the old woodworkers’ adage of never allowing your hand/fingers within one handbreadth of the blade.

11. If you have to cut very small pieces of material, arrange or manufacture some form of ‘shoe’ to carry the timber. If the work piece is exceptionally small,

Changing the Saw Blade

of the blade. Try to “wriggle” the blade free of the saw.

If this is not possible; check that the saw is free in the cut, start the saw, allow it to run up to speed and

‘cut out’ as quickly as possible. The removal of the ‘off cut’ may well prevent the saw jamming again if you resume the original cut.

DISCONNECT THE SAW

FROM THE MAINS SUPPLY!

Put the table back to the level position if it has been tilted. Set the upper blade guide assembly approximately midway in the throat. Open the top and bottom covering doors. Remove the fence and guide rail and place safely aside. Slacken the blade tension by turning the blade tensioning wheel anti-clockwise, until the blade can be easily slipped off the wheels, see fig 30.

Remove the blade carefully, “wriggling” it clear of the upper blade guard and out through the slot in the table. NOW is an excellent time to clean out the interior of the machine; remove the impacted ‘crud’

22 from the tyres, apply a little light oil to the screw threads of the blade tensioner and the tracking control. The pivots and the slides of the top wheel mounting assembly could likewise be lightly oiled.

Changing the Saw Blade

If you are fitting a new blade; it will have been supplied to you “folded”, bound together in this configuration with tape or tie wrap. Also check the blade did not “unfold” inside out. i.e. looking at the right side front of the loop, the teeth should be on the front of the blade, and pointing down. If you can’t arrive at this view, turn the blade inside out from its current position and look again.

Ease the blade over the wheels and locate the blade in both the upper and lower blade guides, see fig 31. Apply some tension to the blade.

Turn the top wheel by hand to ensure the blade will not skip off the wheels and the blade is travelling in the blade guides, see fig 32. Apply a little more tension and check by once again spinning the upper saw wheel by hand.

Loosen the upper blade guide clamp and set the upper blade guide assembly so that the top of the blade guide is level with the centre of the top drive wheel, see fig 33. Re-tighten the clamp.

When you are sure that the blade is “ON” and stable, re-fit the fence rail and fence. Now carry out the procedures as detailed in “Setting up the Saw”.
