1. DESCRIPTION
The BFS35 and BFS45 hand feed floor saws are designed for sawing expansion and
contraction joints, slots for the insertion of traffic control cables, outline cutting of
trenches etc in concrete and asphalt. The BFS35 uses a 350mm-diameter blade and
is powered by a 9-hp petrol engine; the BFS45 uses a 450mm blade and is fitted with
a 13-hp petrol engine. A 350mm blade may be fitted to a BFS45, but a 450mm
should not be fitted to a BFS35 as the engine has insufficient power. A water tank is
an integral part of the machines providing a water supply to both cool the blade and
damp down dust produced while cutting. A wheel brake is fitted to prevent the
machine running away if left unattended on a slope. A lifting eye is provided as part
of the machine.

3. SAFETY PRECAUTIONS AND INFORMATION
Read these operating and safety instructions before using the machine and operate
the machine in accordance with these instructions.
1. Inspect the machine for damage or improper function
2. Make sure the blade is securely fitted in the correct position and with the
correct blade clamping flanges.
3. Before use, visually examine blades for cracks and other damage. Do not use
if damage suspected. Ensure shaft and shaft bearings are not worn.
4. Before starting the machine make sure the blade is clear of the ground.
5. Never force the blade into the cut. Ease blade into the cut gently and push
machine forward with a constant force.
6. Press the stop button to stop the engine. After the engine has stopped turn the
engine switch to off (0).
7. Do not alter the hole in the blade - this will create an out-of-round condition
resulting in blade wobbling, pounding or cracking which could be hazardous.
8. Do not move the machine around the site with the engine running.
9. Before performing any cutting operations, let the tool run for a few seconds
without load. If blade wobble, vibration or unusual noise occurs, stop the tool
immediately. Inspect the blade for damage or incorrect mounting.
10. Do not use side pressure or grind with the side of the blade.
11. Ensure that the arrow on the blade corresponds with the direction of rotation of

M-BFS35-45ow.doc Issue 3225-Aug 01
3
the machine spindle as indicated by the arrow on the blade guard.
12. Ensure that the speed marked on the blade is not less than the no-load blade
speed of the machine.
13. Ensure that the blade is of the correct type for the material to be cut.
14. To prevent accidental starting of the machine the spark plug lead must be
removed before any maintenance or adjustments are carried out on the
machine.
15. Do not attempt to fill fuel tank or oil sump while the machine is running.
16. When operating machines in confined areas, the exhaust fumes must be
ventilated. Do not operate in an explosive atmosphere.
17. Always use blade guard and check for proper function of all guards. Never
defeat the purposes of guards by tying back or removing.
18. Keep bystanders and/or animals out of the work area, particularly at the front
of the machine.
19. Always allow a small amount of water to flow when cutting 'dry' to dampen
airborne dust.
20. Always wear ear protectors.
21. Always wear eye protection.
22. Always wear protective footwear.
23. Place guide arm in raised position when not in use.
24. Check area being cut has no live buried cables at depth being cut.
25. Do not smoke whilst refuelling. Wipe up spilt fuel. Dispose fuel contaminated
wipes safely
26. Ensure work area is well illuminated.
27. Always comply with site safety regulations.
28. This machine is to be used only for cutting concrete, reinforced concrete and
asphalt. It must not be used for cutting any other material or for any other
purpose.
29. This machine must not be modified in any way without written permission of
the manufacturer. Unauthorised modifications are likely to invalidate the
warranty and also result in the machine not conforming to safety regulations.

4. REMOVAL AND FITTING OF BLADES
Remove spark plug lead from petrol engine.
Raise the front of the saw to its maximum height.
Slacken front fixing of blade guard and pivot front of guard upward. It may be
supported in this position with the guide bar arm.
Fit the smaller of the two spanners over the flats in the middle of the drive shaft.
Remove the blade lock nut with the other spanner, turning clockwise. (Left hand
thread).
Remove the outer blade clamping flange and the blade from the drive shaft.
Check the clamping and backing flanges for damage and wear, replace where
necessary.
Ensure that tolerance between spindle and spindle hole in blade is not more than
0.1mm.
Ensure flanges are clean before mounting the blade.
Fit the blade onto the spindle making certain that the blade locates on the spindle
boss and is flush with the backing flange and the arrow on the blade points in the
same direction as arrow on blade guard. If the arrow is unreadable the direction of
rotation is clockwise looking onto the blade side of the machine.
Replace the clamping flange; check it fits snugly against blade.
Replace the blade nut and tighten securely (left hand thread).

Remove spanner holding the drive shaft.
Refit the blade guard and make secure.
Replace spark plug lead (petrol engines).
Check that the sawing guide is in alignment with the blade. Adjust guide if
necessary.
5. OPERATING INSTRUCTIONS
Draw a chalk line along the line of the cut to act as a guide.
Ensure blade is well clear of surface.
Fill the water tank.
Start the engine according to the engine manufacturer’s instructions.
Position the saw, lining up the guide plate (10) on the blade guard with the chalk line.
Move saw forward a few feet and back to check alignment with chalk mark.
Open valve (52) ensuring adequate water is hitting blade.
Loosen cutting depth control lock knob (38).
On full revs lower the blade slowly into the cut to desired depth, indicated on the
appropriate cutting depth scale (46), by rotating handle (44) counter clockwise.
Tighten lock knob (38).

Push saw forwards, gently but firmly following the chalk line.
At the end of the cut loosen lock knob and wind the blade out of the cut by turning
handle clockwise. Slow engine and reposition for subsequent pass.
Stop the engine by slowing to tick-over and pressing the stop button. Turn the
engine switch to off (0) when the engine has stopped.
6. HINTS ON CUTTING
Never plunge the blade harshly into the cut.
The machine can be used with dry and wet cutting blades. Water MUST be used with
wet cutting diamond blades. If using ‘dry’ cutting blades allow sufficient water to flow
to just damp down the dust.
Do not apply downward pressure; the weight of the machine is sufficient for efficient
cutting.
If there is a loss of cutting action check the blade for wear and that it is the correct
type for the material being cut or refer to blade supplier.
Always wear protective goggles, ear defenders, safety footwear and protective
clothing.
The blade is intended for straight line cutting only. Cutting curves can cause stress
cracks or fragmentation of the blade.
If water stops flowing stop cutting until adequate flow is restored.
7. MAINTENANCE
Carry out necessary checks and maintenance on the engine according to the engine
manufacturer's manual.
If cutting dry, due to the dusty conditions, the air filter will need cleaning/changing
much more often - check twice daily - and engine oil will need changing every 20
hours, however, see section 3, para. 19.
Grease blade spindle bearings and tilting yoke bearings weekly.
Check engine and guard nuts and bolts for tightness monthly.
Check drive belts monthly. Retighten if movement at centre of belt span is more than
4mm Replace all belts if any are worn or damaged. See full manual.
Monthly apply a few drops of oil to elevating screw thread.
