MAINTENANCE

CHANGING THE SAW BLADE

Fig. 13 

WARNING!

 Turn off the machine and disconnect the power supply before conducting any maintenance 

work or adjusting any settings.

Fig. 14 

WARNING!

 Band saw blades are extremely sharp! Always wear 

gloves when handling saw blades. Replace the band saw blade when 

it becomes dull. A sharp blade gives the best cuts and helps extend 

the life of your machine. Replacement blades (model no.

 3975-056 

and

 BB5650

) can be purchased from 

wenproducts.com.

1. Remove blade cover by unscrewing the six screws shown in Fig. 13. 
2. Relieve the blade tension by turning the blade tension adjustment 

knob counterclockwise (Fig. 14 - 1).
3. Carefully remove the blade, first from between the guide bearings 

and then from around the wheels.
4. Insert the new blade, first between the guide bearings and then 

around the wheels.

NOTE:

 Install the blade so that the teeth point in the direction of the 

saw’s rotation.
5. Turn the blade tension adjustment knob (Fig. 14 - 1) until the blade is 

taut. The blade is properly tensioned when pressing lightly on the side 

of the blade moves the blade about 1/8 in.

6. Replace the blade cover and install the six screws (Fig. 13).
7. Run the saw at no-load for 10 – 20 seconds to allow the blade to seat on the wheels.
8. Adjust the blade guide in preparation for the next cut.

GENERAL MACHINE CARE

1. Routinely check the condition of the power supply cords and replace them if they are broken, worn or if internal 

wires are showing.
2. Use a brush to remove chips and other debris from the machine. Wipe off any cutting oil or other processing 

residue from the blade, guide bearings, vise, and rest of the saw whenever necessary, and especially before storing 

the saw. 

TIP:

 Apply a light coat of good-quality paste wax to the ways of the vise to protect it against damage and 

rust, and to allow the movable jaw to slide more easily.
3. Keep the vise ways clean. Allowing chips to get under the movable vise jaw can cause damage to the vise.
4. Keep the machine’s hand grip clean in order to prevent accidental slippage during use.
5. If you do not intend to use the machine for longer than a week, clean it and store it in a cool, dry place out of the 

reach of children. Relieve blade tension; this will prolong the life of the blade and prevent warpage.
6. Check the blade condition daily. Replace the blade if it is dull, warped, or shows other signs of damage.
