Airfield Models ( Miter/Cut-Off Saw instructions

These are my instructions for the Microlux Miter/Cut-Off machine.  I lost the original set of instructions but they weren't as good as these anyway.  I wrote these instructions because I was selling my machine and couldn't find the original set at the time.  The machine is sold but why waste a good web page?

There is very little to know about this machine.  There is a safety lever device to help prevent the head from lowering unintentionally and you will need to change the blade or cut-off wheel as needed.  These instructions will cover those items.

As always, be sure the saw is unplugged whenever changing blades.  I can not stress that enough.  The blades are razor thin and you do not want this machine to suddenly turn on while you are working on the blade.  Be sure to wear protective eyewear whenever using this tool.


Features and Use

The saw uses 2Ē blades and cut-off wheels.  As purchased from MicroMark, the saw comes with the bench clamp shown and one saw blade (MicroMark item #15220).  I believe it also comes with the hex keys.

The additional blade and cut-off wheels are accessory items I purchased separately.

The saw base has holes so that it can be mounted to your bench.  The saw also includes a bench clamp you can use for temporary mounting.  The saw must be mounted one way of the other or it will vibrate all over the bench when itís running.

Top Left is the On/Off switch.

To the right of the switch is the protective blade cover.  This cover must be removed to change blades.

To the right is the red safety lever that helps prevent the head from lowering accidentally.

The red safety lever shown in itís ďsafeĒ position.  It is spring loaded to return to this position when the saw head is lifted and the lever is released.

If the lever fails to return then the fastening screw may need to be adjusted slightly.

With the saw off and unplugged, place the item you wish to cut in the built-in vise.  Be sure the vise is tightened securely.

Plug in the saw and turn it on.

Use your right hand to lower the red safety lever.

Use your left hand to lower the saw head to cut the work.  The saw is low torque.  Work slowly and let the saw do the work.  Donít force the saw!

When you've completed the cut, turn off the saw and let the blade come to a complete stop before removing the work that was cut off and the piece left in the vice.


Changing Blades

Always unplug the saw before you remove or change a blade!

Changing the blade in this tool is very fast and simple.  These are the only tools needed to change the blade.

Again, be sure the saw is unplugged before you attempt to change or remove a blade.

Use the small Phillips screwdriver to remove the sheet metal screw that retains the protective blade cover.  If the screw falls off the end of the screwdriver it will land on the base of the tool where it is easily retrieved.

Removing and replacing this screw is easiest to accomplish by moving the safety lever out of the way.

This is a relatively small screw and is metric so donít lose it.
Slide the protective blade cover straight up to remove it.

There is a small hole near the center of the underside of the saw head.

Insert the small hex key into this hole.  Turn the saw blade slowly by hand until the hex key engages the drive shaft which will prevent the blade from turning when you loosen or tighten the blade retaining bolt.

When the hex key has engaged the shaft, use the larger hex key to remove the blade retaining bolt.
The blade, blade washer and retaining screw.  Again, this hardware is metric.  Donít lose it.  That doesn't mean to say that it's ok to lose hardware that's not metric.  The point being, don't lose parts to your stuff when you take it apart.
The drive washer has a shoulder on both sides.  This is important to note because all blades and cut-off wheels that can be used with this saw are not the same thickness.

This side of the drive washer has a taller shoulder and should be used for thicker blades.

When mounting a blade or cut-off wheel, always be sure that the shoulder does not come all the way through the blade which will prevent the blade washer from tightening the saw blade safely.

This side of the drive washer has a shorter shoulder and is for thinner blades.

After determining the proper side of the drive washer to use, put the drive washer back on the drive shaft.

Place the blade on the drive washer.  Note the direction of the blade teeth.

The teeth should throw saw dust toward the back of the saw away from you.

Ensure the blade remains on the drive washer with the shoulder positively engaged in the center hole of the blade.

Place the blade washer over the bolt.  Hand thread the bolt in place while holding the blade.

Use the small hex key again to engage the drive shaft through the bottom of the saw head.

Tighten the blade securely.

Slide the protective blade cover back into place.  Be sure it is fully seated so that the hole for the retaining screw is aligned with the hole in the saw head.

The best way to replace this screw is to use a Phillips screwdriver that fits the screw head well enough that the screw doesnít fall off easily.

Itís also easiest to replace the screw with the safety lever moved down and out of the way.

Thread the screw and driver through the outer hole and start the screw in the inner hole.  If youíre as uncoordinated as I am you may drop the screw a half dozen times before youíre successful.

You can hold the saw over you head sideways so you can put the screw straight into place, but thatís not as much fun as all the swearing you get to do after youíve dropped it for the seventh time.

Thread the safety cover retaining screw until it is just snug.  Donít over-tighten this screw or you will strip the plastic in the saw head.

The saw is now fully assembled and ready to use.
