Raise the blade in front of you, with the teeth pointed upward. (About 1/3 to 1/4 of the blade should be between your hands.) Hold your hands about shoulder-width apart. Place your thumbs on the outside of the blade and your fingers on the inside of the blade. Squeeze the blade inward, making it oval-shaped.



Keeping your wrists locked in position, turn your forearms upward and inward. (The teeth will rotate inward and the bottom of the blade will rotate outward.)



Bring your hands together. The blade will form three loops. Snap the bottom loop upward and catch the three-loop coil in your hands.



Take the three-loop coil in your right hand. Place the band against your palm with the blade teeth pointing outward toward your fingers. Slide the top loop off and let drop.



The remaining two loops of the blade will form a cross. Hold this crossed section out in front of you with the blade teeth pointing toward you. If the right side is crossed OVER the left, hold the crossed section with your right hand. (If the left side of the blade is crossed OVER the right, hold the crossed section with your left hand.)




Keeping the blade in its crossed position, take hold of the side crossed UNDER with your other hand. Use your right (or left) hand to hold only the side crossed OVER. Place your thumbs on the top side of the blade. Put your fingers on the underneath side of the blade.



Hold the blade out and away from you. Slowly move your hands apart while rotating your forearms down and outward.

Our Resharp blade technicians have spent years evaluating blades sent to us by our customers. The advice provided in these sections can help you avoid common mistakes and maximize sawing performance and blade life.

Following is a list of some of the most common preventable causes of premature blade breakage:
Action Result Solution
Sawing too long with a dull or
damaged blade 
Stress in the band  Change the blade at regular
intervals 
    Change the blade immediately
after striking a foreign object or
material.
Flat spots worn on blade guide
roller surface
Vibration and heat in blade Replace blade guide rollers as
necessary.
Grooves in blade guide roller
flange
Damage to back edge of blade Replace blade guide rollers as
necessary. Adjust for proper
clearance between flange and blade.
Frozen or worn blade guide
roller bearings
Heat buidup Lubricate or rebuild roller bearings
as necessary.
Chipped/broken blade guide
wear pads
Damage to blade surface Hone or replace wear pads as
necessary.
Misaligned blade guides Damage to blade surface Check blade guide alignment at
regular intervals and adjust as
necessary.
Blade guide wear pads adjusted
too close to blade
 Heat on blade surface Adjust wear pads for proper
clearance.
Worn blade wheel belts Heat caused by blade contacting
blade wheel
Replace blade wheel belts
Loose or damaged drive belts
Vibration
Adjust or replace drive belts
Sawdust between blade wheel
and blade wheel belts
Vibration, blade slippage Inspect blade wheels for sawdust
at regular intervals and
remove as necessary.
Improper blade tension Stress in band Regularly check blade tension
while sawing and adjust to recommended
range as necessary.
Dropping a tensioned blade
down on a log or cant
Kinks Replace the blade
Excessive sap buildup on blade
or blade wheel belts
Heat buildup
Use waterlube to prevent
buildup. Remove blade and
clean if necessary. Scrape
buildup from belts.
 Ramming blade into end of log
or other stationary objects
Kinks in blade
Replace the blade.
 Excessive pitch buildup on sides
of the teeth
Heat, wavy cuts
Clean or replace blade.
Burning gullet of blade during
sharpening
Breakage point Use coolant during grinding.
Use multiple passes through
sharpener, removing smaller
amounts of material each pass.
Large burrs created during
sharpening
Breakage point
Use coolant during grinding.
Use multiple passes through
sharpener, removing smaller
amounts of material each pass.
Too much or too little hook angle
in tooth
Vibration and/or stress in the
blade and slow cutting speed
Adjust sharpener to provide
proper hook angle for material to
be sawn.
Incomplete sharpening of tooth
profile
Dull blade, breakage point Sharpen complete profile.
Missing the outside corners (cutting
tip) of set teeth
Dull blade Sharpen complete profile.
Removing too little material from
gullet
Fails to remove stress fractures Adjust sharpener to take more
material from gullet of blade.
Worn grinding wheel Steel buildup in wheel reduces
its grinding ability
Replace grinding wheel.
Incorrect grinding wheel shape Redress grinding wheel with
proper profile.
 
Too much or too little set in blade Vibration and/or stress in the
blade and slow cutting speed
Adjust toothsetter to provide
proper set for material to be
sawn.
Toothsetter setting point strikes
tooth too low
Distorts blade body, creating a
place for fractures to occur
Adjust toothsetter so setting
point contacts tooth properly.
Stored blades allowed to rust
Wipe blades dry before storing.
Storing blades without removing
sawdust/sap residue
Oxides and acids can cause
mircroscopic damage to the
blade surface
Clean blade before storing.
