How to fit Urethane tyres

Following these instructions will give you improved band saw performance with better tracking control and eliminating blade
slippage.

CAUTION: ALWAYS unplug your saw while installing these tyres or performing any other maintenance. Use common sense
precautions including wearing eye protection and gloves especially when removing and handling blades. Always follow the
safety instructions in your owner’s manual. If something doesn’t seem safe it is probably not.

1. If possible, it is easier to replace the tyres if the wheels are removed from the saw.
2. Remove the old tyres and clean any debris and adhesive from the wheel. If you are balancing the wheel it should be done at this time.
3. The tyres are undersized and need to be stretched on. Pre-stretch a tyre by pulling on it while it is hooked on a stationary object such as a bench vice. Be sure to avoid sharp edges.
4. Secure the wheel to your work bench for easier installation being careful not to damage the wheel.
5. Place the weld of the tyre on the far side of the wheel and begin stretching the tyre around the wheel in both directions. Use clamps to secure your progress. You may need to use a pry tool to help the tyre onto the wheel. Be sure to avoid sharp edges.
6. Even out the stretch. Do this by inserting a round object such as a dowel rod between the tyre and the wheel and rotating it around the wheel a couple times.
7. Re-assemble your saw and set it up according to your saw’s owner’s manual.

NOTES:

1. Trimming – These tyres can be trimmed. If the tyres you have are too wide they can be trimmed with a quality pair of scissors or sharp utility knife.
2. Adhesives – Adhesive is not required for these tyres. However, in some rare cases for larger sizes, it may be needed. If you need adhesive, we recommend using ‘3MTM Super Weatherstrip Adhesive’.
   a. This can be messy. You may want to protect your work area and hands.
   b. With the tyre already installed reinsert the round object (dowel) between the wheel and tyre.
   c. Apply a small amount of adhesive to the wheel on one side of the dowel. Don’t wait for the adhesive to get tacky.
   d. Move the dowel around the wheel away from the adhesive to expose more of the wheel and repeat the previous step.
   until you have covered most of the wheel.
   e. Rub the tyre as you go to press out any excess adhesive and prevent lumps. Wipe of the excess with a mild solvent
   cleaner and dry.
3. Warm water installations – A common practice installing a band saw tyre is to warm it up before stretching it on. It does
   make it easier but can also cause unwanted problems. If the urethane gets too hot it can alter the characteristics of the
   tyre which keeps it tight to the wheel. You then may need adhesive. If you choose to warm your tyres this way use hot
   tap water DO NOT USE BOILING WATER.
