adJusting blade sPeed
Adjust the blade speed to suit the metal to be cut. the
recommended pulley selections are shown in the chart to
the right.
4.3.1.
disconnect saw from power supply and open the pulley
cover (52).
4.3.2.
loosen the motor securing nuts (12) on the motor plate
to slacken the belt.
4.3.3.
move the belt to the required pulley grooves (see chart).
4.3.4.
tension belt and tighten nuts (12), close and secure the
pulley cover using screw (30) and washer (7).
5. 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 the cutting of light metal in engineering workshops, garages, metal fabricators, etc.
‰
The SM65.V2 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.

5.1.1.
Adjust the blade speed to suit the workpiece (see section 4.3).
5.1.2.
raise the saw arm as far as possible.
5.1.3.
Adjust the stock stop rod (104) to the desired length.
5.1.4.
Raise the handle of quick grip vice (103) to unlock and slide back vice jaw. Insert workpiece against fixed jaw. Slide vice jaw up to
workpiece and firmly press down vice handle to clamp it securely.
5.1.5.
If an angled cut is required slacken lever nut (36). Rotate bevel holder (31) and saw arm to angle required and tighten lever nut (36).
5.1.6.
Adjust the two blade guides, by slackening the knob (99) and the screw (43), so that they are close to the workpiece but will not foul it.
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 the machine until the workpiece is secured and the blade has been lowered to just above workpiece.
5.1.7.
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.
5.1.8.
When sawing is completed disconnect from the power supply, raise blade and remove workpiece.

blade tensiOn
6.1.1.
disconnect the machine from the power supply and then remove blade cover.
6.1.2. `
Adjust the blade tension with knob (95) (fig.2.A), so that light thumb pressure on the blade midway
between the blade wheels produces a deflection of approximately 1mm. dO nOt over tighten.
6.1.3.
replace blade cover, reconnect to power source and run for two to three minutes to seat the blade.
6.1.4.
disconnect saw from the power source, remove blade cover and recheck tension. replace blade cover.
6.2.
blade guide bearing adJustment
6.2.1.
Correct guide bearing (fig.2.B) adjustment is important so that the blade runs smoothly and evenly
without twisting or snagging anywhere. each of the outer guide bearings is mounted on an adjustable
eccentric bush.
6.2.2.
disconnect the machine from the power supply.
6.2.3.
loosen the bearing pivot (59) lock nut (12) while holding the pivot, immediately above the bearing, with
an open ended spanner.
6.2.4.
Turn the pivot to adjust the bearing. The bearing should barely touch the blade (0.001" clearance).
6.2.5.
tighten the lock nut when satisfied with the bearing adjustment.
6.2.6.
Adjust both outer guide bearings.
6.2.7.
When satisfied that the adjustment is accurate, carefully turn the blade wheels by hand to see if the
blade snags or rubs at any point. readjust bearing(s) if necessary.

6.3.2.
loosen hex bolt (fig.3.e) and pivot blade adjustment bracket (fig.3.f) until blade is perpendicular to
vice bed (103).
