This instruction booklet will get you "up-and-running" with the most basic usage of your MAGNA-MATIC balancer. For more complete information on how to service a lawn mower blade refer to the publication "Magna-Matic Guide to Proper Lawn mower Blade Service." 1 Unpack the Balancer Be sure all items listed here were included with your balancer. 1 - Blade Balancer 2 - Instruction Booklet (this booklet) 2 2 Mounting the Balancer You can mount the balancer on a wall, the MAG-10200 Service Center Stand (with your Magna-Matic Lawn mower Blade Sharpener), or the MAG-103 Balancer Test Stand/Mounting Bracket. (see these various ways below) Mounting Conditions: A - Wall must be vertical ± 5º B - Make sure there is enough clearance around the balancer to allow the blade to freely rotate without interference. C - Balancer mounting location should not be subjected to air ow (fans, wind, etc.). Balancer reading accuracy can be compromised by wind/air movement. D - Use (2) bolts 5/16 inch to mount the balancer in its (2) mounting holes. E - See MAG-10200 or MAG-103 Instructions for stand mounting instructions. MAG-10200 Service Center Stand Mounting MAG-103 Test Stand/ Mounting Bracket shown mounted on a work bench Wall Mounting 3 3 Inspecting the Balancer Inspect the balancer for proper function. The balancer must be rst mounted before inspection can be done. A - The Magnet sleeve should slide smoothly over the cone. Manual (hand) force is necessary to move the magnet. With use, the sliding force will decrease - warmer room temperatures will also make the slide move more easily. SEE BELOW IMAGES B - Rotate the balancer - one revolution to assure the bearings are free to rotate. Only a 1/2 of a revolution is necessary to check the balance of a blade.

Lawn mower blade knives have sharp, cutting edges. Wear protective clothing recommended by the blade manufacturer. DO NOT BE INJURED By The Cutting Edges !DO NOT BE INJURED! !SAFETY FIRST! MAGNA-MATIC magnets have a magnetic pull in excess of 120 LBS (using a test place 3.5" x .25" x 3.5".) Magnetic PULL is DRASTICALLY reduced by surface dirt, rust, paint, thin metal, and irregular shapes. DO NOT BE INJURED By a FALLING BLADE !DO NOT BE INJURED! !SAFETY FIRST! ADDITIONAL SAFETY NOTES - READ MAGNA-MATIC balancers use a magnet to hold the lawn mower blade. Blades made of non-magnetic materials will not be held by the magnet. Blades that do not have a CLEAN FLAT STEEL SURFACE and at least 3" in diameter around the center hole; shall not be mounted on the balancer. These blades may not be held by the magnet and may fall. 5 5 Mounting the Blade This will guide you through the process to properly mount a blade on the balancer. 1 - Clean the blade of all dirt and vegetable material. Make sure that the blade is clean down to the steel at the mounting hole, where the magnet will contact the blade. This will greatly improve the magnetic "holding force" of the balancer, and the accuracy of the reading. Use a hand wire brush or the MAG-12000 lawn mower blade cleaning machine to clean a lawn mower blade. 2- Hold the blade with two hands, and locate the center hole of the lawn mower blade on the cone. Now with your index ngers, pull the sliding magnetic chuck towards the blade. The result should be that the blade is now securely located on the cone, and held there by the magnet. SEE BELOW the overhead view of the balancer and blade 3 - Slowly remove your hands and check that the blade is held rmly before completely removing your hands. 1 3 NOTE: Always wear protective gloves when handling lawn mower blades - gloves were not worn in photos to show maximum detail of hand positions. 2 4 5 6 6 Check Blade Straightness This will guide you through the process to see if a blade has become bent from use damage. 1 - While the blade is mounted on the balancer. Turn the blade on the balancer so that it is vertical on the balancer (have one cutting edge pointing to the sky, and one to the ground. 2 - Now position the gauge rod to almost touch the backside of the blade SEE IMAGES TO THE RIGHT 3 - Rotate the blade to compare the distances of one end of the blade to the other. If they are the same - the blade is "at" or "straight." 4 - See your blade manufactures tolerance requirements to determine if the blade should be discarded. NOTE about BLADE STRAIGHTNESS The longer the blade, the greater the deviation that can be allowed between the two blade ends. Conversely, the shorter the blade, the lesser the deviation that can be allowed between the two blade ends. WARNING Do Not attempt to straighten a hardened blade. You may create fractures not visible to the eye. REPLACE ALL BENT BLADES 7 6 Check Blade Straightness General Guide: 18" - 24" long blades can allow up to 3/8" deviation 24" - 28" long blades can allow up to 1/2" deviation 28" - and larger blade can allow up to 5/8" deviation WARNING Do Not attempt to straighten a hardened blade. You may create fractures not visible to the eye. REPLACE ALL BENT BLADES 8 7 Check Blade Balance This will guide you through the process to gauge a blade's out-of-balance condition. 1 - Have the blade mounted on the balancer. 2 - Rotate the blade to a horizontal attitude. SEE BELOW. Then remove your hands and allow the blade to freely rotate. 3 - If the blade remains HORIZONTAL the blade is "HORIZONTALLY IN-BALANCE." 4 - If one end of the blade rotates to the 6 o'clock position of the clock face - THIS IS THE HEAVY END. Material will need to be removed from this end to bring the blade "IN-BALANCE." Remove material from the cutting edge during sharpening - USE a MAGNA-MATIC [MAG-8000 or MAG-9000] to properly sharpen a lawn mower blade. NOTE: The blade will still be "IN-BALANCE-TOLARANCE" if it moves slightly from the horizontal position. ALL MAGNAMATIC Balancers are delicate instruments that are to be operated with manual force only. Do not misuse the balancer. 1 3 2 NOTE: Always wear protective gloves when handling lawn mower blades gloves were not worn in photos to show maximum detail of hand positions. 9 7 Check Blade Balance (cont) This will guide you through the process to gauge a blade's out-of-balance condition. RE-EXPLAINED - (clock face example) Think of a "scale," "balance," or "see-saw." As with any of these, when there is an IMBALANCE of weight on one end it will rotate toward the ground, because of gravity. This is the same way MAGNA-MATIC Precision Static Balancers work. After you have the blade mounted on the balancer, look at the blade on the balancer and think of a CLOCK FACE. With your hand rotate the blade so that it is horizontal, with one end pointing at 3 o'clock and the other end pointing at 9 o'clock. Now let go of the blade, so that it will freely rotate or remain stationary. When a blade is "out-of-balance" the "heavy end" will rotate to 6 o'clock. Take note of which end of the blade falls to 6 o'clock AND how fast it falls. These two factors will indicate which end of the blade is the "heavy end," and how "out-of-balance" the blade is. With experience you will be able to quickly determine how much steel you will need to grind off, by recognizing the speed at which the "heavy end" rotates downward. NOTE: Always wear protective gloves when handling lawn mower blades - gloves were not worn in photos to show maximum detail of hand positions. 10 8 Blade Removal This will guide you how to remove a blade from your MAGNA-MATIC balancer. After you have checked the straightness and the balance of the blade you will need to remove the blade from the balancer. The best way to remove a blade from the balancer without damaging the balancer is to twist the blade. This will release the blade from the magnetic pull with the least amount of force, preventing injury to the operator or damage to the balancer. See BELOW showing the twisting motion. Use the blade as a lever to remove it from the balancer's magnet. NOTE: Always wear protective gloves when handling lawn mower blades - gloves were not worn in photos to show maximum detail of hand positions. 11 9 Balancer CARE This will guide you through the proper care of your MAGNA-MATIC balancer. CARE of your MAGNA-MATIC BALANCER All MAGNA-MATIC balancers are precision, highly accurate measuring instruments to measure the balance condition of rotary blades, hub products, impellers, and the atness/ straightness between the cutting edges of lawn mower blades. Note: run-out gauges can be attached to the guage rod to get run-out readings. !DO NOT DROP OR MISUSE! FOR ALL BALACNERS WITH magnetic sliding chucks BE SURE to always push the magnet (chuck) to the base bracket after you are nished using it. IF DIRT and DUST collect on the slide surface it will damage the slide. This will signicantly reduce the usability of the balancer. If possible cover the balancer with a plastic bag when not in use. DO NOT attempt to clean the greased slide surface. It is greased with an engineered grease that will last the life of the balancer. Using any other grease with damage/reduce the usability of the balancer. FOR ALL BALANCERS DO NOT hit - hammer - drop or cause any other impact to the balancer, it will denitely damage the balancer. DO NOT attempt to replace the bearings. MAGNA-MATIC balancers - if cared for properly will last a lifetime under normal use. 12 10 Balancer Calibration TEST This will guide you through how can test the calibration of your balancer. 1 - Balancer must be mounted to test this. 2 - Make a mark on the face or magnet ring of the balancer (use a felt marker). 3 - Rotate the mark to every position of the clock face (1 o'clock - 2 o'clock - etc.) then let go of the balancer at every position very carefully - to see if it will rotate on its own. Your mark should not move at any position, this shows that the balancer itself is in balance. 4 - Be sure your hand or the mounted surface is not moving, the balancer will pick up the slightest vibration or motion. Air ow/wind will also affect this reading, be sure you are indoors and not near a fan or open window/door. Also make sure the magnet does not have any metal chips in it to throw off the reading. If the unit does not meet any of these requirements return the unit to us for evaluation. RECONDITIONING SERVICE MAGNA-MATIC can recondition your balancer if it has become damaged.
