7.3 Tracking the blade

Tracking position of the blade on the wheels 

There are different opinions on the position that 

the blade should be on the wheels. One group 

of people recommends that with large blades 

you should track the blade so that the teeth 

hang just over the front edge of the rubber. 

The second group recommends that all blades, 

regardless of their size, should run in the center 

of the wheel. The advantage of running the 

large blades with the teeth not contacting the 

rubber of the wheel is that they cannot damage 

the tire. The disadvantage is that the wheel is 

crowned and the blade is not tensioned in the 

center of the band, which gives the blade a 

tendency to wobble or flutter. The advantage 

of running large blades on the center of the 

wheels is that they are tensioned in the center 

of the band and have fewer tendencies to 

wobble and flutter. The disadvantage is that 

blades with a large set on the teeth have a 

tendency to damage the rubber of the tire. 

This does not have a great effect on the 

performance of the bandsaw, as all blades 

are running on the center section of the tire, 

which is not affected. We recommend that you 

balance all blades on the center of the wheels 

for optimum performance and a smoother cut.

1.

 To track the blade, start rotating the wheels 

by hand in the normal direction. As you do this, 

watch the blade to determine where the blade 

wants to track. If the blade is tracking too far 

forward or backward, make small adjustments 

with the tracking adjustment knob located at

the back of the bandsaw while still rotating the 

wheel. Once the blade is tracking in the correct 

position, fully tension the blade and re-track. 

Lock the tracking adjustment handle.

Note.

 Tensioning the blade is covered later in 

the manual.

2.

 Refit the plastic blanking block.

Note:

 The blade must be fully tensioned for 

final tracking.

Note:

 Never track the blade with the saw 

running.

Note.

 There is a window on the side of the 

bandsaw that

allows the blade on the upper flywheel to be 

viewed. This will

assist you while you are tracking the blade.

7.4 Tensioning the blade

There are a lot of opinions on how to tension 

a blade and if you should buy a blade tension 

gauge. Before you purchase a blade tension 

gauge, note the following points:

Most blade tension gauges are fitted to the 

blade and measure the amount the blade 

stretches when you tension it. Each blade 

manufacturer uses a different type of steel with 

different tensile strength. This means that each 

type of steel has a different rate of stretch. For 

example, if you buy a tension gauge from one 

blade manufacturer, it is designed for use on 

their blades, or range of blades, and will not 

necessarily give you accurate readings in lbs/

square inch on another manufacturer’s blades 

because their blades stretch at a different rate. 

In reality, there is nothing quite as quick or as 

accurate as experience. Your machine is fitted 

with a blade tension indicator, which measures 

the deflection of the tension spring on the upper 

flywheel. We recommend that you use it only 

as a general guide and use one of the following 

tensioning procedures to tension the blade.

Method 1

Looking at the top wheel, place your finger at 

the 9 o‘clock position. Move your finger down 

15cm, and, using moderate pressure with 

your thumb, press on the flat of the blade. 

You should get 4 to 6 of deflection. Refit all 

the guards and close the doors. Replace the 

table insert and check that the blade moves 

freely through the table insert. Check that all 

wrenches and loose parts are removed from the 

machine. 

Plug the machine into the power. Turn the 

machine on for a second and switch off. Watch 

how the blade runs. If the blade tracks well,  

then run the machine at full power. If the

Method 2

Tension the blade as described in method 1.

Close all the doors and ensure that all the 

guards are fitted.

Start the band saw and look at the blade from 

the front of the machine. Start to detension the

blade very slowly until the blade starts to flutter 

(wobble from side to side). Then start to tension 

the blade until the blade stops fluttering and is 

running true. Increase the tension on the blade 

by one complete turn on the tension handle. 

You may find that each size and type of blade 

will need more or less additional tension. 

For example, a 1,5mm blade will need less 

additional tension than a 19mm blade. Again, 

experience is the key, and with a little practice 

it will become second nature. The key to all 

tensioning is to get the blade to cut straight 

and true with the minimum amount of tension. 

The less tension that you put on the blade, the 

longer the blade and the machine will last.

Note.

 The upper flywheel has a spring that is 

used to keep a constant pressure on the blade

during use. As the blade cuts, heat is 

generated, which causes the blade length 

to expand. The spring compensates for the 

change in length, and you must never bottom 

out the spring while tensioning the blade.

Note.

 If you are not using the bandsaw for 

extended periods of time (overnight), remove 

the tension on the blade. This will increase 

the life of your blade and the machine. If 

tension is left on the machine, flats or grooves 

can be formed in the rubber of the wheels, 

which will detract from the performance of the 

machine and in extreme cases cause vibration. 

Removing the

tension will greatly enhance the life of the 

machine, bearings and tires. Label the machine 

“detensioned.” On the label, mark the number 

of turns that you detensioned; this way you will 

know how many turns that you have to put back 

on to have your blade correctly tensioned.

Removing the blade from the bandsaw

1. Disconnect the power to the bandsaw.

2. Remove the table split clamp that aligns the 

two table halves.

3. Remove all the guards.

4. Remove the table insert.

5. Remove the tension on the upper flywheel.

6. Open the doors and remove the blade from 

the wheels (use gloves and eye protection) and

gently slide the blade through the table slot.
