4. OPERATION
WARNING! Before operating the bandsaw ensure that you read, understand and apply the safety instructions in Section 1.
NOTE: Before operating the machine certain checks and adjustments will need to be carried out. It is very important that
these instructions are followed carefully in order that the machine is set up safely and correctly.
WARNINg! The machine is designed for light metal cutting work in engineering workshops, garages, metal fabricators, etc.
The SM5.V3 must not be used to cut any other materials (including wood). To do so will invalidate your insurance cover and your
warranty and may cause damage and/or personal injury.
Note: The harder the material being cut, the slower the cutting speed should be. The use of a cutting oil is recommended with the higher
blade speeds.
4.1.
HORIZONTAL CUTTING
4.1.1. Ensure that the saw is
disconnected from the power
supply.
4.1.2. Adjust the blade speed to suit the
workpiece material (see para. 3.3).
4.1.3. Raise the saw arm to the vertical
position.
4.1.4. Adjust the stock stop to the desired
length.
4.1.5. Loosen the fixed vice plate bolts
(11 & 52) and adjust the vice to the
desired angle, see 0-to-450 scale
(39) on bed. Retighten bolts.
Loosen the moveable vice plate
bolt (36) and wind plate up to
fixed plate so that plates are fully
touching. Tighten bolt (36) to
maintain moveable plate parallel to
fixed plate.
4.1.6. Open vice, insert the workpiece
and clamp it securely.
4.1.7. Adjust the two blade guides, by slackening the clamp screws (56 & 66), so that they are close to the workpiece but will not foul it.
4.1.8. Gently lower the arm until the blade is just above the workpiece. Connect the saw to the power supply and start the saw.
DO NOT turn on machine until workpiece is secured and blade has been lowered to just above
workpiece.
4.1.9. Bring the blade into contact with the workpiece and then release the arm. If the blade jams and
the saw does not automatically shut off, immediately disconnect it from the power supply.
Refer to the 'Troubleshooting' section for common problems.
4.1.10. When sawing is completed disconnect from the power supply, raise blade and remove
workpiece.
WARNING! Never raise blade when machine is running and never run machine when
blade is raised (unless correctly set up for vertical cutting).
4.2.
VERTICAL CUTTING
4.2.1. Ensure that the saw is disconnected from the power supply.
4.2.2. Adjust the blade speed to suit the workpiece material (see para. 3.4).
4.2.3. Raise the saw arm to the vertical position and rotate the support plate (18) so that it
engages into the notch in the edge of the main body frame (see fig.2 -18)
4.2.4. Remove the two screws (68) from the end face of the lower blade guide, remove blade
guard (69) and replace with table (55) and its support (56). Loosen the lower blade
guide nut and washer sufficiently to allow the slotted end of the support to pass
between the washer and body frame and then retighten the nut. Retain table by
replacing screws (68) (see fig.2)
4.2.5. Adjust the upper blade guide so that no more blade is exposed than is required to cut the
workpiece.
4.2.6. When cutting keep hands well clear of the blade and always use a push stick for small
workpieces.
4.2.7. When cutting is complete immediately switch off saw.
WARNING! Refit blade guard (69) before using saw for horizontal cutting.
