  Saw with an adjustable frame  

Some saws (usually hacksaws) have adjustable frames to accommodate two different blade lengths.

 

How you adjust the frame will vary depending on the make and model of your hacksaw. One method is shown below:

 
         
  Wing nut on saw  

Step 1 – Loosen wingnut

Remove the blade by turning the wingnut on the side of the frame in an anti-clockwise direction. 

 

This pushes forward a little metal bar on the frame and allows you to unhook the blade from the metal pins.

 
         
  Screw on saw  

Step 2 – Loosen screw 

The frame is held in place by a screw on the top of the hacksaw’s handle.

 

On the top bar of the frame are two holes, one positioned near the handle, and another slightly further down.

 
         
 

Loosen screw with screwdriver

 

The frame is held in place by a screw which tightens into these holes.

 

Use a screwdriver to loosen the screw until you can move the frame back and forth freely.

 
         
  Adjust frame  

Step 3 – Adjust frame

Once the screw is loosened, you can move the frame in or out of the handle, depending on whether you want to shorten or lengthen it.

 

To use a 300mm blade in the saw, slide the frame out of the handle, until the screw is aligned with the second hole.

 
         
  Shorten frame  

To accommodate a 250mm blade, shorten the length of the saw by sliding the frame back into the handle until the screw is aligned with the first hole.

 
         
  Tighten screw  

Step 4 – Tighten screw

Once the screw is aligned with the hole you want, tighten the screw to stop the frame sliding. 

 
         
  insert blade and tighten by turning wing nut.  

Step 5 – Insert blade and tighten wingnut

You can now insert the blade and tighten it by turning the wing nut in a clockwise direction. 

 

When installing a hacksaw blade, ensure the teeth are on the outside of the frame, and are facing away from the handle. This is to ensure the hacksaw cuts on the push stroke
