SAFETY INSTRUCTIONS IMPROPER USE OF GRINDING WHEEL MAY CAUSE BREAKAGE AND SERIOUS INJURY. Grinding is a safe operation if the few basic rules listed below are followed. These rules are based on material contained in the ANSI B7.1 Safety Code for "Use, Care and Protection of Abrasive Wheels". For your safety, we suggest you benefit from the experience of others and follow these rules.

GETTING TO KNOW YOUR GRINDER (Continued) CONTROL PANEL COMPONENT IDENTIFICATION Review the following control panel component descriptions before proceeding with the instructions SYSTEM START SWITCH Powers all control panel systems. Pulls in the main magnetic starter. GRIND SELECTOR SWITCH Variable speed spin Switch must be up to perform spin grinding operations.
Page 11
GETTING TO KNOW YOUR GRINDER (Continued) RELIEF TORQUE DIAL Adjusts the Spin Drive Motor torque (the torque holding the reel blade to the relief finger) when Grind Selector Switch is set at variable Torque Relief. GRINDING WHEEL MOTOR SWITCH On / Off Turn the Grinding Wheel Motor on and off.
GETTING TO KNOW YOUR GRINDER (Continued) TRAVERSE MOTOR SWITCH Turns the traverse drive motor ON/OFF. NOTE: When Grind Selector Switch is set at variable Torque Relief and the Right Proximity Switch is activated, the Indexing Finger Proximity Switch must be activated for the carriage to travel to the left.
Page 13
GETTING TO KNOW YOUR GRINDER (Continued) FRONT AND REAR MOWER MOUNTING The mowing unit is placed into the machine with the rear roller on the V rear clamp support bracket and front roller held with the front tooling clamps. The front tooling bar clamps can be moved from side to side along the tooling so they can be positioned as far apart as possible on varying widths of reels (loosen knob on lower...

GETTING TO KNOW YOUR GRINDER (Continued) TRAVESE LEFT LIMIT TRAVERSE PROXIMITY SENSORS PROXIMITY SENSOR The Traverse Proximity Sensors are used to change the traversing directions for the grinding carriage and are mounted in the Proximity Brackets located in front of the TRAVERSE RIGHT Traverse Base.
Page 15
GETTING TO KNOW YOUR GRINDER (Continued) STEP 2: With the down limit of the Index Finger properly set you may have to adjust the up limit of the Index Finger for 5" (127 mm) diameter reels with reverse helix blades. The up travel limit is restricted to keep the Index Finger in the reel blade index path.
Page 16
GETTING TO KNOW YOUR GRINDER (Continued) RELIEF ANGLE ADJUSTMENT You should always make sure the Reel Positioner Adjuster is at its mid point before you set up a reel to grind. This will allow to adjust the relief angle by approximately 8 degrees in both directions.
Page 17
OPERATING INSTRUCTIONS PREPARE MOWING UNIT FOR SHARPENING When preparing a cutting unit for sharpening, follow the cutting unit manufacturers recommendations for proper maintenance. It is recommended that the reel to be sharpened is thoroughly cleaned. Remove wheels and bed bar, if possible, from the reel. All bedknives must be ground when reels are sharpened.
Page 18
OPERATING INSTRUCTIONS (Continued) INSTALL REEL Move the reel to the approximate position, having the rear roller on the rear clamp support bracket, and front roller on front roller clamps. See FIG. 11. MAKE SURE GRINDING WHEEL IS LOW ENOUGH TO CLEAR THE REEL. YOU CAN LOWER THE GRINDING WHEEL BY DEPRESSING THE INFEED JOG BUTTON DOWN.
OPERATING INSTRUCTIONS (Continued) ALIGN THE REEL FORWARD & BACKWARD NOTE: When measuring to the reel center shaft always make sure you are contacting an area free of dirt and grass. MOUNTING HOLES HORIZONTAL ALIGNMENT Install the horizontal extension bracket onto the carriage front dowel pin and lock in place with knob.
OPERATING INSTRUCTIONS (Continued) VERTICAL ALIGNMENT Install the digital alignment gage vertically on the carriage front dowel pin and pointing at the center of the reel shaft. Lock into place with knob. See FIG. 20 First, measure the left side of the reel as far to the left as possible, set the gage to zero, then measure the right side, at the same distance from reel centerline as the left side.
Page 21
OPERATING INSTRUCTIONS (Continued) ATTACHING THE VARIABLE SPEED SPIN DRIVE UNIT TO THE REEL The spin drive unit attaches to the end of the reel shaft or a drive system component. Consult the cutting unit manufacturer for proper spin drive placement and attachment.
Page 22
OPERATING INSTRUCTIONS (Continued) The coupler/drive assembly includes: RUBBER SLEEVE COUPLER: This is placed in the corresponding flange coupler already mounted in the spin drive shaft. See FIG. 25. DRIVE COUPLER ADAPTER ASSEMBLY: This is mounted to the rubber coupler. ADAPTER SLEEVE: Connects the rubber coupler to the square drive adapter.
Page 23
OPERATING INSTRUCTIONS (Continued) REEL DRIVE ADAPTERS This grinder is equipped with an adapter that transfers the rotation from the spin drive gear box coupling to a 1/2"male square. To operate the grinder you need an adapter from this 1/2" male square to the reel shaft.
Page 24
OPERATING INSTRUCTIONS (Continued) SETUP PROCEDURE FOR SPIN DRIVE RPM VERSUS TRANSVERSE SPEED SPIN DRIVE RPM SPIN DRIVE RPM IS VERY IMPORTANT IN ACHIEVING A QUALITY GRIND. USE CARE IN ESTABLISHING THE SPIN DRIVE RPM, PER THE INSTRUCTIONS BELOW. Generally, the Spin Drive RPM will be between 180 RPM (45%) and 380 RPM (100%). The speed required to spin a specific reel is dependant on reel diameter, the number of reel blades, and reel hardness.
Page 25
OPERATING INSTRUCTIONS (Continued) VERIFY GRINDING WHEEL TO REEL END FRAME CLEARANCE Install the 5" (127 mm) x 1 " (25mm) grinding wheel. Adjust the relief finger with the front hand knob so it clears the grinding wheel diameter (about 1/32" [0.8 mm]).
Page 26
OPERATING INSTRUCTIONS (Continued) Turn on the Grinding Wheel Motor and the Spin Drive Motor. Set the Spin speed at approximately 200 rpm for 10" (254 mm) reels and 300 rpm for 5" (127 MM) reels. (Refer to Spin Drive Speed information on page 23). Make sure spin rotation is the same as the grinding wheel - clockwise (CW) looking from right end.
Page 27
OPERATING INSTRUCTIONS (Continued) RELIEF GRIND Replace the grinding wheel with the appropriate wheel for relief grinding. Generally a 5" (127 mm) Dia. x 3/8" (10 mm) wide, will be used. As the reel diameter gets smaller and the number of blades increases the relief grinding wheel diameter must get smaller.
Page 30
OPERATING INSTRUCTIONS (Continued) Reset the Traverse Limit Proximity Switch so the grinding wheel clears the reel at bot h ends by approximately 1/16" (1.5 mm). Pull the left side plunger pin and rotate the Finger and Body Assembly up (back, away from the operator) into the relief position until the left side plunger pin locks into position.
Page 31
OPERATING INSTRUCTIONS (Continued) Close and latch doors, then turn the Spin Drive motor on. NOTE: The spin drive will apply torque load against the fingers. Set the Relief Torque Potentiometer at approximately 15. NOTE: Free turning reels may need a lower value than 15. Stiff reels or reels with a drive train may need a higher torque than 15.
